Seacracker 33 / Tufglas 33 / Trintella IIA


Brief details



Tylers/ Lifeline Ltd.

A fast cruiser-racer from the 1970s/80s, the Seacracker 33 was also known as a Trintella IIA and Tyler Tufglas 33. Like all Van de Stadt designs, they have an excellent reputation for performance and seaworthiness. Externally, they resemble Contessa 32s and S&S 34s, with moderate beam, long overhangs, and a wineglass section fin and skeg hull with an excellent ballast ratio, all these characteristics producing good seagoing performance with high ultimate stability.

The Seacracker 33 and Trintella IIA designs are essentially the same boat, designed by Van de Stadt in 1965 as a fast seaworthy cruiser-racer. The Trintellas were originally built in Holland by Anne Wever, and in the early 1970s the design was taken up by Tylers of Rochester in Kent, the UK-built boats being very slightly more heavily constructed than the Dutch versions. Just 12 Seacracker 33s were built by Tylers before they changed the name to the Tufglas 33 in 1976. Production of these continued until 1978 when a fire at the factory destroyed the moulds. Tyler hulls were sold to many yards for fit-out, so both standards of fit-out and layout will vary.


As is common with hulls sold both to a number of boatbuilders and to home builders, there can be sometimes significant variation in fitout. A substantial engine box under the companionways seems to be common.

Seacracker 33

On a 'standard' Seacracker 33 there would be a smaller chart table, with an additional quarter berth behind it. On this yacht a much larger outboard facing chart table has been fitted, and the lack of a quarter berth allows an extra cockpit locker on the starboard side
