Pratt reported ownership of 1,400,000 shares of Gander Mountain Company Common Stock pursuant to a Schedule 13 G filed on February 22, 2005. Such shares were and remain beneficially owned by the David C. Pratt Irrevocable Grantor Retained Annuity Trust dated 12/1/92 (the "Trust") rather than by David C. Pratt individually. Although David C. Pratt individually is a current beneficiary of the Trust, he has no participation in the investment decisions with respect to trust assets or to the voting of interests held by the Trust. For purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, securities held by the Trust are deemed to be beneficially owned by Mark R. Gale (as the sole owner and controlling person of Calco, Inc. which is the sole trustee of the Trust). This Schedule 13 D supercedes the Schedule 13 G previously filed by Mr. Pratt and reflects the transactions and events which occurred on August 16, 2005, announced by the Registrant, Gander Mountain Company on August 17, 2005, and reported by the Registrant in its Current Report on Form 8-K filed with the SEC on August 17, 2005 (including the election of Mr. Pratt as a director of the Registrant). Although Mr. Pratt has no voting or investment power over the shares or assets held by the Trust, Mr. Pratt and Mr. Gale acknowledge, without so admitting, that they could be deemed to constitute a "group" with respect to the Trust's respective investments in the Registrant and accordingly jointly file this Schedule 13 D. Mr. Pratt and Mr. Gale are not related by blood or marriage. ITEM 1. SECURITY AND ISSUER. This Schedule 13 D relates to the Common Stock, par value $.01 per share, of Gander Mountain Company (the "Registrant") whose principal executive offices are at 180 East Fifth Street, Suite 1300 St. Paul, Minnesota 55101 ITEM 2.

(e) not a party to any such proceedings. (f) United States. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. On August 16, 2005, the Trust purchased from the Registrant a Floating Rate Convertible Subordinated Note (the "Note") in the principal amount of $20,000,000 for cash in an amount equal to the face value. Funding for the purchase of the convertible debt instrument giving rise to such deemed ownership was provided from the Trust's own funds (as was funding for the purchases of shares of Common Stock previously held by the Trust). The Note matures on August 16, 2010 and is subject to prepayment by the Company, without penalty, at any time after August 16, 2007. The Note is initially convertible into Common Stock at $16.00 per share (equivalent to 1,250,000 shares in the aggregate) subject to anti-dilution adjustments. The Note bears interest at 7.0% per annum for two years after which it will float in relation to the federal funds rate subject to a maximum of 8.5% per annum. The terms of the note are more fully described in the Registrant's Form 8-K Current Report filed with the SEC on August 17, 2005 (the "Company 8-K"). The form of the Note and the Purchase Agreement between the Registrant and the Trust, including exhibits thereto, are filed as exhibits to the Company 8-K and any description herein is qualified in its entirety to the full text of such instruments. ITEM 4. PURPOSE OF THE TRANSACTION. The acquisition of the Stock and the purchase of the Note by the Trust were in each case undertaken for general investment purposes. Either Mr. Pratt or the Trust may, from time to time, acquire additional shares of stock or participate in financing transactions relating to the Registrant or may determine to sell portions or all of the investments currently held. No transactions undertaken by Mr. Pratt or by the Trust were undertaken with a view to changing or effecting any of the events listed or described in items (a) through (j) of Item 4, notwithstanding the fact as reported above that Mr. Pratt was elected to a newly-created vacancy on the board of directors of the Registrant coincident with the investment made by the Trust. Although Mr. Pratt does not join the board of directors with a specific transactional agenda, it is his expressed and current intention to work with the Registrant's management team to assist in realizing the growth potential he perceives in the Registrant. 5 -------------------------------------------------------------------------------- CUSIP No. 36471 P 10 8 13D Page 6 of 7 Pages -------------------------------------------------------------------------------- ITEM 5.

As a director of the Registrant, Mr. Pratt may be entitled to indemnification in accordance with applicable law and the Registrant's by-laws. The Note Purchase Agreement between the Registrant and the Trust includes provisions limiting or restricting (i) the ability of the Trust to participate in any proxy contest or solicitation relating to shareholder proposals, (ii) convening a meeting of the shareholders of the Registrant, (iii) to acquire additional securities which would result in the Trust and its affiliates (including Mr. Pratt) holding in excess of 20% of the 6 -------------------------------------------------------------------------------- CUSIP No. 36471 P 10 8 13D Page 7 of 7 Pages -------------------------------------------------------------------------------- outstanding stock of the Registrant (assuming conversion of the Note), (iv) depositing shares of the Registrant's stock into a voting trust or otherwise entering a voting agreement with respect to such shares, (v) making a tender offer for securities of the Registrant or proposing a merger, business combination, sale of assets, liquidation or other extraordinary corporate transaction, (vi) engaging in a short sale or other hedging transaction relating to the Registrant's common stock, (vii) making any public announcement or advise, assist or encourage any other party to propose any such transaction, or (viii) requesting that the Registrant waive any of the foregoing restrictions. The Note Purchase Agreement also restricts sales, transfers or pledges of securities of the Registrant held by the Trust for a three year period. Such agreement is subject to waiver by the Registrant's independent directors, does not apply to sales, if any, in accordance with the limitations of Rule 144 and is subject to expiration before the end of the three year period upon the occurrence of certain events or conditions. A request by the Trust to waive any such provisions creates a right in the Registrant to purchase the Note or the shares of stock into which it has been converted. The Registrant has agreed with the Trust to file a Registration Statement under the Securities Act of 1933, as amended, to permit the resale of the shares of Common Stock into which the Note is convertible. The Note Purchase Agreement also contains cross-indemnification provisions between the Trust and the Registrant and usual and customary terms relating to participation in certain underwritten offerings. As indicated in Item 3 above, any description herein of provisions of the Note Purchase Agreement is qualified in its entirety by reference to the full text and terms of such agreement. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.
