It didn't, but initial concerns about the economy, and mistrust generated by the Enron scandal, began to give way to relief, as signs of an economic rebound grew stronger. The Dow Jones Industrial Average, with its blue chip roster of stocks, actually gained ground in the first three months of 2002, returning 4.29%. The broader Standard & Poor's 500 Index was essentially flat, at 0.28%, while the tech-heavy Nasdaq Composite Index continued to reflect the technology and telecommunications sectors' woes, losing 5.30% through March 31, 2002. Bond results were more muted than last year. These last two years couldn't have provided a more vivid example of the importance of being well diversified, not only among different asset classes, such as stocks, bonds and cash, but also among various types of each, such as growth or value stocks of different capitalizations. Two disappointing years of stock performance could also be a reason to re-evaluate with your investment professional whether you are still on track to meet your long-term financial goals. It's possible that downsized results, and modified expectations, could foster some changes in your investing strategies. And now is certainly a good time to perform this review, given the increased opportunities for retirement and college savings offered in President Bush's major tax-cut legislation enacted in June 2001. While the stock market is still digesting the latest economic data, and trying to determine its impact on earnings, it is becoming increasingly clear that the economic and corporate profit cycles have begun to turn. So we remain encouraged, and confident in the resilience of the economy, the financial markets and the nation. Sincerely, /S/ MAUREEN R. FORD Maureen R. Ford, Chairman and Chief Executive Officer YOUR FUND AT A GLANCE The Fund seeks to provide high current income, consistent with modest growth in capital, by investing in a diversified portfolio of dividend-paying preferred and common equity securities. Over the last six months * Changing expectations about the economy and the direction of interest rates prompted stock and bond market volatility. * Fears of rising interest rates pressured preferred stocks. * The Fund's energy-related holdings performed well as oil and natural gas prices skyrocketed.

MANAGERS' REPORT BY GREGORY K. PHELPS, FOR THE PORTFOLIO MANAGEMENT TEAM John Hancock Patriot Premium Dividend Fund I Preferred stocks -- one of the two primary areas of focus for John Hancock Patriot Premium Dividend Fund I -- struggled during the past six months amid post--September 11 jitters and fears of rising interest rates. Because of their relatively high dividends, preferred stocks tend to rise in value like bonds when interest rates fall, and fall in value when rates are on the upswing. In October and November, the Federal Reserve Board aggressively cut interest rates in an attempt to steady global financial markets and prevent an economic slowdown from worsening. Preferred stocks rallied along with the overall bond market. But from December through March, preferreds went into a funk. An evolving consensus that an economic rebound was just around the corner, and strong indications that the Fed was at the end of its current cycle of cutting rates, prompted investors to gravitate from the more defensive segments of the market -- like preferreds -- into more economically sensitive groups. "Utility common stocks ...spent the first half of the period in a valiant struggle against the many elements that were stacked against them." UTILITY COMMON STOCKS BRIGHTEN Utility common stocks -- the Fund's other primary investment focus -- spent the first half of the period in a valiant struggle against the many elements that were stacked against them. The same gravitation toward growth stocks that muted preferred stocks' returns in October and November hurt utility common stocks as well. The collapse of energy-trading company Enron also was a major drag on utility stocks -- both common and preferred -- in the final weeks of 2001. The company, once one of the nation's largest companies and a major component of the Dow Jones Utility Average, filed for bankruptcy in December as investors lost confidence in the company's financial reporting. Fears of "Enronitis" spread across the utility sector, causing it to post losses during January. But then conditions turned more favorable in February and March. Despite a warmer-than-normal winter, electricity, oil and natural gas prices rose dramatically in response to stronger industrial demand and heightened tensions in the Middle East. Furthermore, there was growing confidence that most utilities weren't subject to the types of problems that brought down Enron. "Thanks to our focus on high-quality investments ...we completely avoided the collapse of Enron..." FUND PERFORMANCE For the six months ended March 31, 2002, John Hancock Patriot Premium Dividend Fund I returned 4.16% at net asset value. By comparison, the average income and preferred closed-end fund returned 6.89%, according to Lipper, Inc. The Fund had a larger-than-average stake in utility common stocks, which accounted for its underperformance relative to its peers. The Dow Jones Utility Average -- which tracks the performance of 15 electric and natural gas utilities -- returned 3.47%, and the broader stock market, as measured by the Standard & Poor's 500 Index, returned 10.99%. Thanks to our focus on high-quality investments -- which is driven by our research process and emphasis on good company fundamentals -- we completely avoided the collapse of Enron, never having held any of its securities in the Fund. We also avoided other stocks that came under pressure due to Enron-like concerns, including companies with energy-trading operations such as Williams Company, Calpine and AES. But our best performers during the six-month period were companies involved in the production and distribution of oil and natural gas. Anadarko Petroleum and Devon Energy, for example, each posted strong gains as energy prices shot higher. Our long-term commitment to well-managed, regionally based electric transmission and distribution companies served us well. Progress Energy, for example, performed reasonably well, thanks in part to its enjoying one of the country's fastest growing customer bases. Other good regional performers included those with higher-than-average dividends, such as NSTAR (the former Boston Edison) and OGE, one of the lowest-cost electric generators in the country. [Table at top left-hand side of page entitled "Top five industry groups." The first listing is Utilities 72%, the second is Oil & Gas 9%, the third Broker services 6%, the fourth Media 4%, and the fifth Finance 2%.] One of our biggest detractors during the period was the common stock of electric provider Western Resources, which performed poorly when a couple of regulatory rulings went against the company and put in jeopardy the company's planned merger with Public Service of New Mexico. [Pie chart in middle of page with heading "Portfolio diversification As a percentage of net assets on 3-31-02." The chart is divided into three sections (from top to left): Preferred stocks 63%, Common stocks 33% and Short-term investments & other 4%.] OUTLOOK At its most recent meeting in March 2002, the Fed decided not to raise interest rates. Since then, Fed Chairman Alan Greenspan seems to have grown more optimistic by the week that the economy is in the midst of a recovery. Given that, it appears unlikely that interest rates are going to decline any time soon. On the other hand, we don't think that economic growth for 2002 will be so robust that it forces the Fed to substantially raise rates either, given what we believe is a rather anemic economy. With this backdrop in mind, we don't think that preferreds will appreciate in price as much as they did during 2001 when interest rates fell dramatically. So we're likely to focus on preferred stocks that are selling below par and on high-coupon cushion preferreds, both of which should help immunize the portfolio from rising interest rates as the economy strengthens. [Table at top of page entitled "SCORECARD." The header for the left column is "INVESTMENT" and the header for the right column is "RECENT PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is Anadarko Petroleum followed by an up arrow with the phrase "Rising energy prices boost earnings prospects." The second listing is Progress Energy followed by an up arrow with the phrase "Rate settlement in Florida; growth lifts earnings." The third listing is Western Resources followed by a down arrow with the phrase "Unfriendly regulatory actions cast doubt about planned merger."] "...it appears unlikely that interest rates are going to decline any time soon." In contrast, we believe utility stocks can perform better than they have during previous economic upturns, which typically favor faster-growing stocks. Our belief is based on the fact that most utilities have attractive earnings growth prospects and their stocks are priced lower than they have been in decades from a price-to-earnings perspective. So the sector looks cheap relative to other industry sectors. In our view, "Enronitis" has unfairly tainted the entire utility sector, with high-quality companies selling at very cheap prices. Furthermore, we believe that 2001 served as a useful reminder for shareholders about the importance of diversification. Because of that, we don't think that utility stocks will be left out in the cold even if the economy were to enjoy a quick and sharp rebound. This commentary reflects the views of the portfolio management team through the end of the Fund's period discussed in this report. Of course, the team's views are subject to change as market and other conditions warrant.

NOTES TO STATEMENTS Unaudited NOTE A Accounting policies John Hancock Patriot Premium Dividend Fund I (the "Fund") is a diversified, closed-end management investment company registered under the Investment Company Act of 1940. Significant accounting policies of the Fund are as follows: Valuation of investments Securities in the Fund's portfolio are valued on the basis of market quotations, valuations provided by independent pricing services or at fair value as determined in good faith in accordance with procedures approved by the Trustees. Short-term debt investments maturing within 60 days are valued at amortized cost, which approximates market value. The Fund determines the net asset value of the common shares each business day. Investment transactions Investment transactions are recorded as of the date of purchase, sale or maturity. Net realized gains and losses on sales of investments are determined on the identified cost basis. Federal income taxes The Fund qualifies as a "regulated investment company" by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required. Net capital losses of $260,189 that are attributable to security transactions incurred after October 31, 2000 are treated as arising on October 1, 2001, the first day of the Fund's next taxable year. Dividends, interest and distributions Dividend income on investment securities is recorded on the ex-dividend date or, in the case of some foreign securities, on the date thereafter when the Fund identifies the dividend. Interest income on investment securities is recorded on the accrual basis. Foreign income may be subject to foreign withholding taxes, which are accrued as applicable. The Fund records distributions to shareholders from net investment income and realized gains on the ex-dividend date. Such distributions are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Use of estimates The preparation of these financial statements, in accordance with accounting principles generally accepted in the United States of America, incorporates estimates made by management in determining the reported amount of assets, liabilities, revenues and expenses of the Fund. Actual results could differ from these estimates. Dutch Auction Rate Transferable Securities (DARTS) preferred stock Series A Dividends on the DARTS, which accrue daily, are cumulative at a rate which was established at the offering of the DARTS and have been reset every 49 days thereafter by auction. Dividend rates ranged from 1.50% to 2.89% during the period ended March 31, 2002. The DARTS are redeemable, at the option of the Fund, at a redemption price equal to $100,000 per share, plus accumulated and unpaid dividends on any dividend payment date. The DARTS are also subject to mandatory redemption at a redemption price equal to $100,000 per share, plus accumulated and unpaid dividends, if the Fund is in default on its asset coverage requirements with respect to the DARTS. If the dividend on the DARTS shall remain unpaid in an amount equal to two full years' dividends, the holders of the DARTS, as a class, have the right to elect a majority of the Board of Trustees. In general, the holders of the DARTS and the common shares have equal voting rights of one vote per share, except that the holders of the DARTS, as a class, vote to elect two members of the Board of Trustees, and separate class votes are required on certain matters that affect the respective interests of the DARTS and common shares. The DARTS have a liquidation preference of $100,000 per share, plus accumulated and unpaid dividends. The Fund is required to maintain certain asset coverage with respect to the DARTS, as defined in the Fund's by-laws. NOTE B Management fee and transactions with affiliates and others The Fund has an investment management contract with John Hancock Advisers, LLC (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group, LLC. Under the investment management contract, the Fund pays a monthly management fee to the Adviser at an annual rate of 0.50% of the Fund's average weekly net assets plus 5.00% of the Fund's weekly gross income. The Adviser's total fee is limited to a maximum amount equal to 1.00% annually of the Fund's average weekly net assets. For the period ended March 31, 2002, the advisory fee incurred did not exceed the maximum advisory fee allowed. The Fund has an administrative agreement with the Adviser under which the Adviser oversees the custodial, auditing, valuation, accounting, legal, stock transfer and dividend disbursing services and maintains Fund communications with the shareholders. The Fund pays the Adviser a monthly administration fee at an annual rate of 0.10% of the Fund's average weekly net assets. Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors and/or officers of the Adviser and/or its affiliates, as well as Trustees of the Fund. The compensation of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer for tax purposes their receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments into other John Hancock funds, as applicable, to cover its liability for the deferred compensation. Investments to cover the Fund's deferred compensation liability are recorded on the Fund's books as an other asset. The deferred compensation liability and the related other asset are always equal and are marked to market on a periodic basis to reflect any income earned by the investment as well as any unrealized gains or losses. The Deferred Compensation Plan investments had no impact on the operations of the Fund.

INVESTMENT OBJECTIVE AND POLICY The Fund's investment objective is to provide high current income, consistent with modest growth of capital, for holders of its common shares. The Fund will pursue its objective by investing in a diversified portfolio of dividend- paying preferred and common equity securities. The Fund's non-fundamental investment policy, with respect to the quality of ratings of its portfolio investments, was changed by a vote of the Fund's Trustees on September 13, 1994. The new policy, which became effective October 15, 1994, stipulates that preferred stocks and debt obligations in which the Fund will invest will be rated investment grade (at least "BBB" by S&P or "Baa" by Moody's) at the time of investment or will be preferred stocks of issuers of investment-grade senior debt, some of which may have speculative characteristics, or, if not rated, will be of comparable quality as determined by the Adviser. The Fund will invest in common stocks of issuers whose senior debt is rated investment grade or, in the case of issuers who have no rated senior debt outstanding, whose senior debt is considered by the Adviser to be of comparable quality. On November 20, 2001, the Trustees approved the following investment policy change effective 12-15-01: Under normal circumstances the Fund will invest at least 80% of its net assets in dividend-paying securities. "Net assets" is defined as Fund's net assets plus borrowings for investment purposes. In addition, the Fund will notify shareholders at least 60 days prior to any change in this 80% investment policy. DIVIDEND REINVESTMENT PLAN The Fund provides shareholders with a Dividend Reinvestment Plan ("the Plan") which offers the opportunity to earn compounded yields. Each holder of common shares will automatically have all distributions of dividends and capital gains reinvested by State Street Bank and Trust Company, 225 Franklin Street, Boston, Massachusetts 02210, as agent for the common shareholders, unless an election is made to receive cash. Holders of common shares who elect not to participate in the Plan will receive all distributions in cash, paid by check, mailed directly to the shareholder of record (or, if the common shares are held in street or other nominee name, then to the nominee) by the Plan Agent, as dividend disbursing agent. Shareholders whose shares are held in the name of a broker or nominee should contact the broker or nominee to determine whether and how they may participate in the Plan. If the Fund declares a dividend payable either in common shares or in cash, nonparticipants will receive cash and participants in the Plan will receive the equivalent in common shares. If the market price of the common shares on the payment date for the dividend is equal to or exceeds their net asset value as determined on the payment date, participants will be issued common shares (out of authorized but unissued shares) at a value equal to the higher of net asset value or 95% of the market price. If the net asset value exceeds the market price of the common shares at such time, or if the Board of Trustees declares a dividend payable only in cash, the Plan Agent will, as agent for Plan participants, buy shares in the open market, on the New York Stock Exchange or elsewhere, for the participant's accounts. Such purchases will be made promptly after the payable date for such dividend and, in any event, prior to the next ex- dividend date, after such date except where necessary to comply with federal securities laws. If, before the Plan Agent has completed its purchases, the market price exceeds the net asset value of the common shares, the average per share purchase price paid by the Plan Agent may exceed the net asset value of the common shares, resulting in the acquisition of fewer shares than if the dividend had been paid in shares issued by the Fund. Participants in the Plan may withdraw from the Plan upon written notice to the Plan Agent. Such withdrawal will be effective immediately if received not less than ten days prior to a dividend record date; otherwise, it will be effective for all subsequent dividend record dates. When a participant withdraws from the Plan or upon termination of the Plan as provided below, certificates for whole common shares credited to his or her account under the Plan will be issued and a cash payment will be made for any fraction of a share credited to such account. The Plan Agent maintains each shareholder's account in the Plan and furnishes monthly written confirmations of all transactions in the accounts, including information needed by the shareholders for personal and tax records. Common shares in the account of each Plan participant will be held by the Plan Agent in non-certificated form in the name of the participant. Proxy material relating to the shareholder's meetings of the Fund will include those shares purchased as well as shares held pursuant to the Plan. There will be no brokerage charges with respect to common shares issued directly by the Fund. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open market purchases in connection with the reinvestment of dividends and distributions. In each case, the cost per share of the shares purchased for each participant's account will be the average cost, including brokerage commissions, of any shares purchased on the open market plus the cost of any shares issued by the Fund. There are no other charges to participants for reinvesting dividends or capital gain distributions, except for certain brokerage commissions, as described above. The automatic reinvestment of dividends and distributions will not relieve participants of any federal income tax that may be payable or required to be withheld on such dividends or distributions. Participants under the Plan will receive tax information annually. The amount of dividend to be reported on Form 1099-DIV should be (1) in the case of shares issued by the Fund, the fair market value of such shares on the dividend payment date and (2) in the case of shares purchased by the Plan Agent in the open market, the amount of cash used to purchase them (including the amount of cash allocated to brokerage commissions paid on such purchases). Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan as applied to any dividend or distribution paid subsequent to written notice of the change sent to all shareholders of the Fund at least 90 days before the record date for the dividend or distribution. The Plan may be amended or terminated by the Plan Agent after at least 90 days written notice to all shareholders of the Fund. All correspondence or additional information concerning the Plan should be directed to the Plan Agent, State Street Bank and Trust Company, at P.O. Box 8209, Boston, Massachusetts 02266-8209 (telephone 1-800-426-5523).
