The Sigma 36 is a signature David Thomas design evolved from the ever-successful 33 with the intention of providing more spacious accommodation whilst retaining the cruiser-racer ethos of the sigma's. The large double aft berth, extra beam and length ensure that the Sigma 36 can be cruised more extensively and today provides excellent value for money.

This is a much-upgraded example of the Sigma 36 from 1984, benefiting from full new B&G electronics from 2020, new sprayhood, recent standing rigging, upgraded primary winches plus much more. Read further for details and get in touch to book your viewing.
