To Shareholders of the Fund:

The purpose of this Notice is to advise you that an Annual Meeting of the
Shareholders of Narragansett Insured Tax-Free Income Fund (the "Fund") will be
held:

Place:       (a)    at the Rhode Island Convention Center

                    Providence, Rhode Island;


Time:        (b)    on October 28, 2005
                    at 9:00 a.m. Eastern Daylight Time;


Purposes:    (c)    for the following purposes:

                     (i) to elect eight Trustees; each Trustee
                     elected will hold office until the next
                     annual meeting of the Fund's shareholders or
                     until his or her successor is duly elected
                     (Proposal No. 1);

                     (ii) to ratify (that is, to approve) or
                     reject the selection of Tait, Weller & Baker
                     as the Fund's independent registered public

Who Can
Vote What
Shares:      (d)    To vote at the Meeting, you must have
                    been a shareholder on the Fund's records at
                    the close of business on August 1, 2005 (the
                    "record date"). Also, the number of shares
                    of each of the Fund's outstanding classes of
                    shares that you held at that time and the
                    respective net asset values of each class of
                    shares at that time determine the number of
                    votes you may cast at the Meeting (or any
                    adjourned meeting or meetings).

                                By order of the Board of Trustees,

                                 Proxy Statement

                                  Introduction

     The purpose of the Notice preceding this Proxy Statement is to advise you
of the time, place and purposes of an Annual Meeting of the Shareholders of
Narragansett Insured Tax-Free Income Fund (the "Fund"). The purpose of this
Proxy Statement is to give you information on which you may base your decisions
as to the choices, if any, you make in voting.

     The Fund's Manager (the "Manager") is Aquila Investment Management LLC, 380
Madison Avenue, Suite 2300, New York, NY 10017, a subsidiary of the Fund's
founder, Aquila Management Corporation. The Fund's principal underwriter (the
"Distributor") is Aquila Distributors, Inc., 380 Madison Avenue, Suite 2300, New
York, NY 10017. The Fund's Investment Sub-Adviser is Citizens Investment
Advisors, a department of Citizens Bank of Rhode Island (the "Sub-Adviser"), One
Citizens Plaza, Providence, RI 02903.

     A copy of the Fund's most recent annual report will be sent to you without
charge upon written request to the Distributor, at the above address, or by
calling 800-437-1020 toll-free or 212-697-6666.

     This Notice and Proxy Statement are first being mailed on or about
September 22, 2005.

     You should read this Proxy Statement prior to voting. If your shares are
registered in the name of your broker or someone other than yourself, you may
authorize that person to vote your shares. If your shares are registered in your
name, then you may vote in one of three ways:

         (1) Proxy Card

     The enclosed proxy card authorizes the persons named (or their substitutes)
to vote your shares; the Fund calls these persons the "proxy holders." As to the
election of Trustees you may authorize the proxy holders to vote your shares for
the entire slate indicated below by marking the appropriate box on the proxy
card or by merely signing and returning your proxy card with no instructions. Or
you may withhold the authority of the proxy holders to vote on the election of
Trustees by marking the appropriate box. Also, you may withhold that authority
as to any particular nominee by following the instructions on the proxy card.

     As to the other matter listed on the proxy card, you may direct the proxy
holders to vote your shares on this proposal by marking the appropriate box
"For" or "Against" or instruct them not to vote your shares on the proposal by
marking the "Abstain" box. If you return your signed proxy card and do not mark
a box on the proposal, the proxy holders will vote your shares for that
proposal.

         (2) Telephone Voting

     To vote your shares by telephone, call the toll-free number on your proxy
card. You will be prompted to enter the control number on your proxy card.
Follow the recorded instructions using your proxy card as a guide. If you vote
by phone, you need not return the proxy card by mail.

         (3) Internet Voting

     To vote your shares by the Internet, please contact the Fund at the
Internet address shown on your proxy card. You will be prompted to enter the
control number on your proxy card. Follow the instructions on the screen, using
your proxy card as a guide. If you vote by the Internet, you need not return the
proxy card by mail.

         General Information

     You may end the power of the proxy holders to vote your shares by: (i) so
notifying the Fund in writing; (ii) signing a new and different proxy card (if
the Fund receives it before the old one is used); (iii) voting your shares at
the meeting in person or by your duly appointed agent; or (iv) calling the toll
free number provided or contacting the Fund's Internet address, both of which
are detailed on your proxy card, entering your control number and revoking your
previous vote.

     Proxies for shares held by brokers in "street name" and not voted or marked
as abstentions will be counted for purposes of determining a quorum. They will
be counted as present in determining voting results, and will therefore have the
same effect as negative votes.

     The Fund is sending you this Notice and Proxy Statement in connection with
the solicitation by its Trustees of proxies to be used at the Annual Meeting to
be held at the time and place and for the purposes indicated in the Notice or
any adjourned meeting or meetings. Whenever it is stated in this Proxy Statement
that a matter is to be acted on at the Meeting, this means the Meeting held at
the scheduled time or any adjourned meeting or meetings.

     The Fund pays the costs of the solicitation. Proxies are being solicited by
the use of the mails; they may also be solicited by telephone, facsimile and
personal interviews. Brokerage firms, banks and others may be requested to
forward this Notice and Proxy Statement to beneficial owners of the Fund's
shares so that these owners may authorize the voting of their shares. The Fund
will pay these firms their out-of-pocket expenses for doing so.

     On the record date, the Fund had four classes of shares outstanding. All
shareholders of the Fund are entitled to vote at the meeting. Each shareholder
on the record date is entitled to one vote for each dollar (and a proportionate
fractional vote for each fraction of a dollar) of net asset value (determined as
of the record date) represented by full and fractional shares of any class held
on the record date. On the record date, the net asset value per share of each of
the Fund's outstanding classes of shares was as follows: Class A Shares, $10.66;
Class C Shares, $10.66; Class Y Shares, $10.66; and Class I Shares, $10.65. The
meeting is expected to act only upon matters that affect the Fund as a whole:
the election of Trustees and the selection of an independent registered public
accounting firm. On matters that affect the Fund as a whole, all shareholders of
the Fund, including the shareholders of all classes of shares of the Fund, are
entitled to vote at the meeting.

     On the record date, the total number of shares outstanding for each class
of shares was as follows: Class A Shares, 9,709,732; Class C Shares, 1,748,841;
Class Y Shares, 2,840,929; and Class I Shares, 97,336.

     On the record date, the following holders held 5% or more of a class of the
Fund's outstanding shares. On the basis of information received from the
institutional holders, the Fund's management believes that all of the shares
indicated are held by them for the benefit of clients.

     The Fund does not currently pay fees to any of the Fund's officers or to
Trustees affiliated with the Manager or the Sub-Adviser. For its fiscal year
ended June 30, 2005 the Fund paid a total of $105,874 in compensation and
reimbursement of expenses to the Trustees. No other compensation or remuneration
of any type, direct or contingent, was paid by the Fund to its Trustees.

     The Fund is one of the 11 funds in the Aquilasm Group of Funds, which
consist of tax-free municipal bond funds, money-market funds and an equity fund.
The following table lists the compensation of all nominees for Trustee who
received compensation from the Fund or from other funds in the Aquilasm Group of

     Class A Shares may be purchased without a sales charge by the Fund's
Trustees and officers.

     The Fund's Manager is a wholly-owned subsidiary of Aquila Management
Corporation ("AMC"), founder of each fund in the Aquilasm Group of Funds. As of
August 31, 2005, these funds had aggregate assets of approximately $4.3 billion,
of which approximately $2.5 billion consisted of assets of the tax-free
municipal bond funds. AMC's address is the same as that of the Manager. AMC is
controlled by Mr. Lacy B. Herrmann, through share ownership directly, through
two trusts and by his wife. During the fiscal year ended June 30, 2005, the Fund
incurred $753,282 in management fees, of which $579,069 was waived, $22,277 was
paid to the Manager, and the balance was paid to the Sub-Adviser.

     During the fiscal year ended June 30, 2005, $157,240 was paid under Part I
of the Fund's Distribution Plan to Qualified Recipients with respect to the
Class A Shares, of which $4,011 was retained by the Distributor. With respect to
Class C Shares, during the same period $141,377 was paid under Part II of the
Plan and $47,126 was paid under the Shareholder Services Plan. Of the total
payments under Parts I and II of the Plan of $188,503, the Distributor received
$45,058. All of such payments were for compensation. With respect to Class I
Shares, during the same period $433 was paid under Part III of the Plan and
$1,298 was paid under the Shareholder Services Plan.

     The Distributor currently handles the distribution of the shares of the
funds in the Aquilasm Group of Funds, including the Fund. Under the Distribution
Agreement, the Distributor is responsible for the payment of certain printing
and distribution costs relating to prospectuses and reports as well as the costs
of supplemental sales literature, advertising and other promotional activities.
The shares of the Distributor are owned 24% by Diana P. Herrmann, 72% by Mr.
Herrmann and other members of his immediate family and the balance by current
and former employees of Aquila Investment Management LLC.

Other Information on Trustees

     The Trustees have appointed a standing Audit Committee consisting of all of
the Trustees who are "independent" and are not "interested persons" of the Fund,
as that term is defined in the Investment Company Act of 1940. The members of
the Audit Committee are Vernon R. Alden, Timothy J. Leach, William J.
Nightingale, James R. Ramsey and J. William Weeks. The Committee (i) selects the
Fund's independent registered public accounting firm (subject to shareholder
ratification); (ii) reviews the methods, scope and result of audits and the fees
charged; and (iii) reviews the adequacy of the Fund's internal accounting
procedures and controls. Selection of the independent registered public
accounting firm is also ratified by the Board of Trustees. The Audit Committee
held one meeting during the Fund's last fiscal year. The Board of Trustees has
adopted a written charter for the Audit Committee.

     During the Fund's last fiscal year, the Board of Trustees held five
meetings. Each current Trustee was present for at least 75% of the total number
of Board meetings and Audit Committee meetings (if such Trustee was a member of
that committee).

         The Fund's policy is that all Trustees who can do so attend the Annual
Meeting.

         The Fund has a Nominating Committee, consisting of all of the
Independent Trustees. The Nominating Committee held one meeting during the last
fiscal year. The committee will consider nominees recommended by the
shareholders who may send recommendations to the committee in care of the
Manager at 380 Madison Avenue, New York, NY 10017. The charter of the Nominating
Committee is available on the Fund's website at www.aquilafunds.com.

         Since the beginning of the Fund's most recently completed fiscal year,
no Trustee purchased or sold more than 1% of the outstanding shares of any class
of shares of the Manager.

Vote Required

    To be elected, each nominee must receive the affirmative votes of a majority
of the shares present.

                            Ratification or Rejection
                                 of Selection of
                  Independent Registered Public Accounting Firm
                                (Proposal No. 2)

         Tait, Weller & Baker ("TWB") has been preliminarily selected as the
Fund's independent registered public accounting firm for the fiscal year ending
June 30, 2006 by the Fund's Audit Committee, after requesting from the Manager
and receiving the results of interviews and evaluations of a number of possible
firms. The selection has been preliminarily ratified by the Board of Trustees,
including a majority of the Independent Trustees. TWB has concentrated its
accounting practice primarily in the mutual fund industry for more than 40 years
and is one of the industry's largest providers. It is anticipated that
immediately prior to the Annual Meeting of Shareholders, selection of TWB by the
Audit Committee and ratification by the Board of Trustees will be formally
confirmed at meetings attended in person by members of the Audit Committee and
Board, respectively.

         KPMG LLP ("KPMG") has served as the Fund's independent registered
public accounting firm for all of the Fund's fiscal years from its inception
through its fiscal year ended June 30, 2005. Throughout that period, KPMG's
reports on the Fund's financial statements, including those for the Fund's two
most recent fiscal years, contained no adverse opinion or disclaimer of opinion.
No reports were qualified or modified as to uncertainty, audit scope, or
accounting principles. Since inception and including the last two fiscal years
and the subsequent period through the date of this proxy statement, there have
been no disagreements with KPMG on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure, and
there were no reportable events of the kinds required to be disclosed under
regulations applicable to proxy statements.

         The following table represents fees for professional audit services
rendered by KPMG for the audit of the Fund's annual financial statements for the
fiscal years ended June 30, 2004 and 2005, and fees billed for other services
rendered by KPMG.

All other fees                           0               0
                                    ------          ------

    Total                          $23,275         $25,005
                                    ======          ======

 (1) Tax fees consisted of fees for tax consultation and tax compliance
services.

         KPMG did not perform any services during the fiscal year for the Fund's
investment adviser (the Manager) or any entity controlling, controlled by or
under common control with the Manager that provides services to the Fund.

         All audit and non-audit services performed by KPMG on behalf of the
Fund or non-audit services performed on behalf of affiliated entities within the
investment company complex where such engagement relates directly to the
operations and financial reporting of the Fund are pre-approved by the Audit
Committee. Services to be considered between meetings of the Committee are
pre-approved by a selected member of the Committee in accordance with applicable
regulations and subject to additional procedures established by the Committee.

         The Audit Committee has reviewed all services performed and fees
charged by KPMG and has accepted its representation that it is independent. The
Audit Committee has reviewed all services to be performed and fees to be charged
by TWB and in recommending appointment of TWB for the fiscal year ending June
30, 2006 has accepted its representation that it is independent.

         It is expected that representatives of neither firm will be present at
the meeting but representatives of each firm will be available should any matter
arise requiring their presence.

                                  Vote Required

         Approval requires the affirmative votes of a majority of the shares
present.


                                   Receipt of
                              Shareholder Proposals

         Under the proxy rules of the Securities and Exchange Commission,
shareholder proposals meeting tests contained in those rules may, under certain
conditions, be included in the Fund's proxy statement and proxy card for a
particular annual meeting. One of these conditions relates to the timely receipt
by the Fund of any such proposal. Under these rules, proposals submitted for
inclusion in the proxy material for the Fund's next annual meeting after the
meeting to which this Proxy Statement relates must be received by the Fund not
less than 120 days before the anniversary of the date stated in this Proxy
Statement for the first mailing of this Proxy Statement. The date for such
submission could change, depending on the scheduled date for the next annual
meeting; if so, shareholders will be notified.

         The fact that the Fund receives a shareholder proposal in a timely
manner does not insure its inclusion in the Fund's proxy material, since there
are other requirements in the proxy rules relating to such inclusion.

                                 Other Business

         The Fund does not know of any other matter which will come up for
action at the Meeting. If any other matter or matters properly come up for
action at the Meeting, including any adjournment of the Meeting, the proxy
holders will vote the shares which your proxy card, telephone or Internet vote
entitles them to vote, in accordance with their judgment on such matter or
matters, except as noted. That is, by signing and returning your proxy card or
by voting by telephone or the Internet, you give the proxy holders discretionary
authority as to any such matter or matters.
