Sigma 36

  • £29,950 inc Vat
  • Helensburgh, United Kingdom


    The Sigma 36 "Full Circle" is a very well maintained example of a classic David Thomas design. Having been cruised by her current owner, she now boasts a long list of upgrades, including instrumentation, headsail furling and heating.

    A great boat to sail with with the ability to either cruise and race, a viewing is highly recommended.
