I agree. How the boat is constructed is vital, but this is often glossed over. Vinyl-ester resins are a lot better than polyester (but not as good as epoxy) in terms of resistance to osmosis (and most other properties).
However, many manufacturers use a small amount of vinyl-ester, but cleverly word their brochure to suggest upon casual reading that the full hull layup
is vinyl-ester. Even salesmen get this wrong, so do your homework.
My impression is that Lagoon is one of the brands that suffers few osmosis problems, but comparing the detail of the hull layup
and construction methods with competing brands will give you a better idea of the long term susceptibility.
