TRITIUM is designed as a fast, exciting little trimaran, equally suitable for multihull "speed freaks" and for family outings and coastal cruising.

Tritium is designed for amateur construction.  

The hulls are in lightweight sandwich of PVC foam core and GRP skins.      

Throughout the construction process, attention is given to simplicity - high-tech building techniques are avoided.     A limited amount of Carbon fibre is employed only in the cross-beams, where its higher strength make it even economical.

The boat is not foldable to preserve simplicity of construction, but can be disassembled for wintering or transport.

A complete set of construction drawings, with full-scale patterns of all framing panels, and building sequence instructions, is available for sale.
