          required  to be  identified  in the report but who is not a  reporting

     (2)  If any of the shares beneficially owned by a reporting person are held
          as a member  of a group  and the  membership  is  expressly  affirmed,
          please check row 2(a). If the reporting person disclaims membership in
          a group or describes a  relationship  with other  persons but does not
          affirm the existence of a group, please check row 2(b) [unless it is a
          joint filing pursuant to Rule  13d-1(k)(1) in which case it may not be
          necessary to check row 2(b)].

     (3)  The 3rd row is for SEC internal use; please leave blank.

     (4)  Classify the source of funds or other consideration used or to be used

     (5)  If disclosure of legal  proceedings or actions is required pursuant to

          named reporting person is a natural person.  Otherwise,  furnish place
          of  organization.  (See Item 2 of Schedule 13D.)

          accordance  with  the  provisions  of

     (13) Item 5 of  Schedule  13D.  All  percentages  are to be rounded  off to
          nearest  tenth  (one place  after  decimal  point).

          (12) Check if the aggregate  amount reported as beneficially  owned in
               row (11)  does not  include  shares  which the  reporting  person
               discloses in the report but as to which  beneficial  ownership is
               disclaimed  pursuant  to Rule 13d4 [17 CFR  240.13d-4]  under the
               Securities Exchange Act of 1934.

               appropriate  symbol  (or  symbols,  i.e.,  if  more  than  one is
               applicable,  insert all applicable symbols) on the form:

Notes: Attach as many copies of the second part of the cover page as are needed,
     one  reporting  person  per page.

     Filing persons may, in order to avoid unnecessary duplication, answer items
     on  the  schedules  (Schedule  13D,  13G or  14D-1)  by  appropriate  cross
     references to an item or items on the cover page(s). This approach may only
     be used  where the  cover  page item or items  provide  all the  disclosure
     required by the schedule  item.  Moreover,  such a use of a cover page item
     will result in the item  becoming a part of the  schedule  and  accordingly
     being  considered  as "filed" for purposes of Section 18 of the  Securities
     Exchange Act or otherwise subject to the liabilities of that section of the
     Act.

     Reporting  persons may comply with their cover page filing  requirements by
     filing  either  completed  copies of the  blank  forms  available  from the
     Commission,  printed or typed facsimiles,  or computer printed  facsimiles,
     provided the documents filed have identical formats to the forms prescribed
     in the Commission's  regulations and meet existing  Securities Exchange Act
     rules as to such matters as clarity and size (Securities  Exchange Act Rule
     12b12).

              SPECIAL INSTRUCTIONS FOR COMPLYING WITH SCHEDULE 13D


Under Sections 13(d) and 23 of the Securities Exchange Act of 1934 and the rules
and  regulations  thereunder,  the  Commission  is  authorized  to  solicit  the
information required to be supplied by this schedule by certain security holders
of certain issuers.

Disclosure of the  information  specified in this schedule is mandatory,  except
for  I.R.S.  identification  numbers,  disclosure  of  which is  voluntary.  The
information  will be used for the primary  purpose of determining and disclosing
the holdings of certain  beneficial  owners of certain equity  securities.  This
statement will be made a matter of public  record.  Therefore,  any  information
given will be available for inspection by any member of the public.

Because of the public nature of the  information,  the Commission can utilize it
for a variety of purposes,  including referral to other governmental authorities
or securities  self-regulatory  organizations for  investigatory  purposes or in
connection with litigation involving the Federal securities laws or other civil,
criminal or regulatory statutes or provisions. I.R.S. identification numbers, if
furnished,  will assist the  Commission  in  identifying  security  holders and,
therefore,   in  promptly  processing  statements  of  beneficial  ownership  of
securities.  Failure to disclose the  information  requested  by this  schedule,
except for I.R.S. identification numbers, may result in civil or criminal action
against the persons  involved for violation of the Federal  securities  laws and
rules promulgated thereunder.

                              General Instructions

A.   The item  numbers and  captions of the items shall be included but the text
     of the  items  is to be  omitted.  The  answers  to the  items  shall be so
     prepared as to indicate clearly the coverage of the items without referring
     to the text of the items.  Answer every item. If an item is inapplicable or
     the answer is in the negative, so state.

B.   Information  contained in exhibits to the statements may be incorporated by
     reference  in  answer or  partial  answer  to any item or  sub-item  of the
     statement  unless  it would  render  such  answer  misleading,  incomplete,
     unclear or confusing.  Material  incorporated by reference shall be clearly
     identified in the reference by page,  paragraph,  caption or otherwise.  An
     express  statement that the specified  matter is  incorporated by reference
     shall  be  made  at  the  particular  place  in  the  statement  where  the
     information  is  required.  A copy  of  any  information  or a copy  of the
     pertinent  pages  of  a  document  containing  such  information  which  is
     incorporated  by  reference  shall be submitted  with this  statement as an
     exhibit  and  shall be  deemed  to be filed  with  the  Commission  for all
     purposes of the Act.

C.   If the statement is filed by a general or limited  partnership,  syndicate,
     or other group, the information called for by Items 2-6,  inclusive,  shall
     be given with respect to (i) each partner of such general partnership; (ii)
     each partner who is denominated as a general  partner or who functions as a
     general  partner of such  limited  partnership;  (iii) each  member of such
     syndicate  or group;  and (iv) each  person  controlling  such  partner  or
     member.  If the statement is filed by a corporation or if a person referred
     to in (i), (ii),  (iii) or (iv) of this  Instruction is a corporation,  the
     information  called for by the above  mentioned  items  shall be given with
     respect to (a) each executive officer and director of such corporation; (b)
     each person  controlling such  corporation;  and (c) each executive officer
     and director of any  corporation  or other person  ultimately in control of
     such corporation.

Item 1.   Security and Issuer

This  Amendment  No. 13 to Schedule 13D on the Class A Common Stock of Spinnaker
Industries,  Inc. (the "Issuer") is being filed on behalf of the  undersigned to
amend the Schedule 13D, as amended (the  "Schedule  13D"),  which was originally
filed December 10, 1987. Unless otherwise indicated,  all capitalized terms used
herein but not defined  herein  shall have the same  meaning as set forth in the
Schedule 13D. This  Amendment is filed to reflect the reduction in the amount of
shares of the Issuer's Class A Common Stock  beneficially owned by the reporting
persons  resulting from the  transaction  described at Item 5(c) below.

Item 2. Identity and Background

Items 2 is amended:

(a)  To reflect that reporting  person M-tron  Industries,  Inc., a South Dakota
     corporation,  changed  its name to "Lynch  Systems,  Inc."  incident to the
     merger of Lynch Systems, Inc., a Delaware corporation, with and into M-tron
     Industries,  Inc. on December 5, 2000. M-tron Industries, Inc. survived the
     merger and,  upon the merger,  changed  its name to "Lynch  Systems,  Inc."
     (hereinafter  "Lynch  Systems").

(b)  To reflect that the address of the principal place of business of reporting
     person  Lynch  Systems  has  been  changed  to  601   Independent   Street,
     Bainbridge, Georgia 31717.

(c)  To reflect that the address of the principal place of business of reporting
     person Lynch Corporation, an Indiana corporation ("Lynch Corporation"), has
     been changed to 50 Kennedy Plaza, Suite 1250, Providence, RI 02903.

The Reporting Persons do not admit that they constitute a Group.

During the last five years, none of the Reporting Persons has been convicted in
a criminal proceeding (excluding traffic violations or similar misdemeanors),
and no such person was a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which he was or is
subject to a judgment, decree or final order enjoining future violations of, or
prohibiting or mandating activities subject to, federal or state securities laws
or finding any violation with respect to such laws.

For  information  required by  Instruction C to Schedule 13D with respect to the
executive  officers and  directors of the  foregoing  entities and other related
persons  (collectively,  "Covered  Persons"),  reference  is made to  Schedule I
annexed hereto and incorporated herein by reference.

Item 4.   Purpose of Transaction

The  purpose  of the  transaction  described  in Item 5(c) was to  permit  Lynch
Corporation, effective September 30, 2001, to deconsolidate Issuer for financial
reporting  purposes and prospectively  account for its ownership of Issuer using
the equity method of accounting.

Prior to September 30, 2001, Lynch Corporation (through Lynch Systems) owned 48%
of the equity of Issuer (60% voting  control)(both  calculated with reference to
the  Issuer's  Class A Common Stock and Common  Stock on a combined  basis);  as
such, under generally  accepted  accounting  principles,  Lynch  Corporation was
required  to record all of the losses of Issuer  since the  non-Lynch  interests
were not  required  to  absorb  their  share of the  losses  (52%)  after  their
investment was fully absorbed by losses.

On September 30, 2001, Lynch Corporation's ownership interest and voting control
of Issuer  were  reduced to 42% and 49%,  respectively,  (both  calculated  with
reference  to the  Issuer's  Class A Common Stock and Common Stock on a combined
basis) due to the disposition of shares of Issuer  described in Item 5(c) below.
As a result,  effective September 30, 2001, Lynch Corporation has deconsolidated
Issuer and will  prospectively  account for its  ownership  of Issuer  using the
equity method of accounting..

Item 5.   Interest in Securities of the Issuer

(a)  The  aggregate  number and  percentage of Securities to which this Schedule
     13D relates is 1,829,063 shares, representing 51.3% of the 3,566,067 shares
     of Class A Common Stock outstanding as reported by the Issuer's most recent
     form 10-Q for the  quarter  ended  June 30,  2001.  The  Reporting  Persons
     beneficially own those Securities as follows:


                                               Shares of         % of

     Mario J.  Gabelli  and Lynch  Corporation  are  deemed  to have  beneficial
     ownership of the Securities  beneficially owned by Lynch Systems.  Mario J.
     Gabelli  disclaims  beneficial  ownership  of the  1,829,063  shares of the
     Issuer's stock owned by Lynch Systems.

(b)  Each of Lynch Systems and Lynch  Corporation  has the sole power to vote or
     direct the vote and sole power to dispose or direct the  disposition of the
     subject  1,829,063 shares of the Issuer's stock.

(c)  On September  26, 2001,  Lynch  Systems made a charitable  contribution  of
     430,000  shares  of  Issuer's  Class  A  Common  Stock  to  Roger  Williams
     University of Bristol,  Rhode Island. The purpose of the transaction was to
     permit Lynch  Corporation,  effective  September 30, 2001, to deconsolidate
     Issuer for financial  reporting purposes and prospectively  account for its
     ownership  of Issuer  using the  equity  method  of  accounting.

     Prior to September 30, 2001,  Lynch  Corporation  (through  Lynch  Systems)
     owned 48% of the equity of Issuer (60% voting control)(both calculated with
     reference  to the  Issuer's  Class A Common  Stock  and  Common  Stock on a
     combined basis); as such, under generally accepted  accounting  principles,
     Lynch  Corporation was required to record all of the losses of Issuer since
     the  non-Lynch  interests  were not  required to absorb  their share of the
     losses (52%) after their investment was fully absorbed by losses.

     As a result  of the  subject  transaction,  Lynch  Corporation's  ownership
     interest  and  voting  control  of  Issuer  were  reduced  to 42% and  49%,
     respectively (both calculated with reference to the Issuer's Class A Common
     Stock  and  Common  Stock on a  combined  basis).  As a  result,  effective
     September 30, 2001, Lynch  Corporation has  deconsolidated  Issuer and will
     prospectively  account for its  ownership of Issuer using the equity method
     of  accounting.

After  reasonable  inquiry and to the best of my knowledge and belief, I certify
