Re: New Trimaran build
Why aluminium ? Composite works for all your other boats ?
Such a dissimilar material seems incongruous ?
That design is 20 years old, if I redesigned it now I would have the frames built from fibreglass as the later design are. I wanted to get a consistent result for amateur builders and as the aluminium would have to be TIG welded it would have to be built by an aluminium fabricator, hopefully with consistent results.
