KVH Industries, Inc.
50 Enterprise Center
Middletown, Rhode Island 02842
Ladies and Gentlemen:


       We have acted as counsel for KVH Industries, Inc., a Delaware corporation
(the "Company"), in connection with the preparation and filing with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
of a Registration Statement on Form S-8 (the "Registration Statement") relating
to the offering by the Company of up to 1,000,000 shares (the "Shares") of its
common stock, $.01 par value, issuable pursuant to the KVH Industries, Inc. 2003
Incentive and Nonqualified Stock Option Plan (the "Plan").

       In arriving at the opinions expressed below, we have examined and relied
on the following documents:

       (i)    the Registration Statement;

       (ii)   a copy of the Plan;

       (iii)  the Certificate of Incorporation of the Company, as amended as of
              the date hereof;

       (iv)   the By-Laws of the Company, as amended as of the date hereof; and

       (v)    the records of meetings and consents of the Board of Directors and
              stockholders of the Company provided to us by the Company.

       In addition, we have examined and relied on the originals or copies
certified or otherwise identified to our satisfaction of all such other records,
documents and instruments of the Company and such other persons, and we have
made such investigations of law, as we have deemed appropriate as a basis for
the opinions expressed below. We have assumed the genuineness of all signatures
and the authenticity of all documents submitted to us as originals and the
conformity to the original documents of all documents submitted to us as
certified or photostatic copies.

       We express no opinion other than as to the General Corporation Law of the
State of Delaware.

       Based upon the foregoing, we are of the opinion that:

       1.     The Company has the corporate power necessary for the issuance of
              the Shares under the Plan, as contemplated by the Registration
              Statement.

       2.     The Shares have been duly authorized and, when issued against
              payment of the agreed consideration therefor in accordance with
              the respective exercise prices therefor as described in the Plan,
              will be validly issued, fully paid and non-assessable.

       We consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement.

                                                 Very truly yours,


                                                 FOLEY HOAG llp
