On Styrene vs. Fibreglass or wood.
A matter of personal preference but I have noted over the years that styrene Is great for smaller hulls, very malleable and welded joints seem to be forever. Easy to repair and even to rebuild If required.
GRP/fibreglass In larger hulls Is essentially self supporting (apart from transverse struts across the beam) and gloss coat can be finished coat. Have never used on smaller hulls, perhaps a prejudice but It doesn't appeal. Structural repairs are easy but gel coat repairs less so.
I prefer wood for 'proper' plank on frame but can achieve same In styrene, especially on small hulls. Personally I think styrene and wood/plywood are Interchangeable for chined hulls large(ish) or small.
For scratch built round bilge hulls there Isn't, In my view, an alternative to wood (I don't want to make a 'plug' and then a fibreglass mould - I only want one!)
Sorry for the ramble but hope you can see where I'm coming from even If It doesn't really Inform!
