                        (i) to elect seven Trustees; each Trustee

                        (ii) to ratify (that is, to approve) or

               "record date"). Also, the number of shares of each of the Fund's

                    Narragansett Insured Tax-Free Income Fund
               380 Madison Avenue, Suite 2300, New York, NY 10017
                                 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 voting
decisions.

     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 Sub-Adviser is Citizens Investment Advisors, a
department of RBS Citizens, N.A. (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 4, 2007.

     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) 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.

         (3) 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.

         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, $10.39;
Class C Shares, $10.39; Class Y Shares, $10.39; and Class I Shares, $10.39. 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, 9,614,173; Class C Shares, 1,338,830;
Class Y Shares, 3,340,231; and Class I Shares, 79,709.

     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.

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 Timothy J. Leach, William J. Nightingale, James R.
Ramsey, J. William Weeks and Laureen L. White. 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 four
meetings. Each current Trustee was present for at least 75% of the total number
of Board meetings and meetings of which such Trustee was a member.

         The Fund's policy is that all Trustees who can do so attend the Annual
Meeting. At the last Annual Meeting all of the Trustees were present.

         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. Recommendations of nominees
from shareholders are not treated differently than proposals from other sources.
The charter of the Nominating Committee is available on the Fund's website at
www.aquilafunds.com.

         Shareholder communications intended for the Board of Trustees (or one
or more specified Trustees) may be sent to them in care of the Manager at the
above address.

         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, Sub-Adviser or the parents or subsidiaries of either.

                                  Vote Required

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

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

         Tait, Weller & Baker LLP ("TWB"), which is currently serving as the
Fund's independent registered public accounting firm, has been selected by the
Fund's Audit Committee and ratified by the Board of Trustees, including a
majority of the Independent Trustees, as the Fund's independent registered
public accounting firm for the fiscal year ending June 30, 2008. Such selection
is submitted to the shareholders for ratification or rejection.

         The following table represents fees for professional audit services
rendered by TWB for the audit of the Fund's annual financial statements, and
fees billed for other services rendered by TWB for the fiscal years ended June
30, 2006 and 2007.

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

         TWB did not perform any services during the last 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 TWB 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 TWB and has accepted TWB's representation that it is independent in
recommending re-appointment of it for the fiscal year ending June 30, 2008.

         TWB has no direct or indirect financial interest in the Fund, the
Manager or the Sub-Adviser. It is expected that representatives of TWB will not
be present at the meeting but will be available should any matter arise
requiring their presence.


                                  Vote Required

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


                              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 of this Proxy Statement.
Accordingly, a shareholder proposal intended to be presented at the Fund's 2008
annual meeting must be received by the Fund by May 6, 2008 in order to be
included in the Fund's proxy material relating to that meeting. 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.

         A shareholder wishing to provide notice of a proposal in the manner
prescribed by Rule 14a-4 (c)(1) under the Securities Exchange Act of 1934 must
submit written notice of the proposal to the Fund by July 18, 2008.


                                 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, Internet or telephone 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 the Internet or telephone, you give the proxy holders discretionary
authority as to any such matter or matters.
