Catamaran Converter 21

With a 30hp 2 stroke outboard the Converter 21 will achieve approx. 20 knots while a 4hp will push it along at 6 to 7 knots.

Performance under sail depends upon the catamaran hulls and rig used. Large high buoyancy hulls and big rig will create a very fast boat but even with standard 16 foot hulls and rig the Converter 21 sails very well.

The boat is fast and very responsive. Due to the lift forward and the flare of the hull this boat is very dry. It planes readily and the fine entry slices effortlessly through the chop, while the large flat planing surface aft effectively damps out pitching.

Designed to be launched, rigged and sailed single-handed.

Beams: 6061 T6 marine/structural grade aluminium

Cabin and deck: Foam cored fibreglass/polyester.

Hull: Solid fibreglass/polyester resin, made from female moulds.

The Converter 21 has been designed as a very family-friendly boat with a large, rope-free cockpit. There is a covered 'cuddy' cabin, which can be further enlarged by enclosing the entire cockpit with a custom tent which rests on aluminium poles, the boom, and the targa bar. This big space allows daysailing, weekend trips or extended coastal cruising.

Assembly: the cat hulls are unbolted from their cross beams and re-bolted onto the Converter's lateral beam. The stays from the cat are lengthened slightly using short lengths of spectra or other low-stretch rope. This is all very simple. Any beach catamaran can be used.

The Converter 21 consists of the main trimaran hull and a sliding beam system (which includes the nets). These components are to be used in conjunction with the hulls and rig of a 16 foot to 21 foot catamaran (which the owner purchases separately) to create a folding trimaran. This is a very cost effective way to own a trailerable trimaran.
