hull bracing

Been looking at the various strengthening methods employed in rib hulls, seems there are two main choices, wood or foam?? am i right, are there anymore?? Some boats seem to have alot less bulkheads than others, i presume its the trade off between weight and rigidity is it?? Some also seem to stretch full height to deck and others are almost flat with chine edges. Can anyone shed any light and or pics on the pros and cons

Thanks gt

..so what's the option? Properly “glassed in”, high quality marine ply for transoms... does it have a rival?

I was hoping that someone would know it's origin... as far as I know, it's Mark Pascoe.

Many F1 powerboats are still made from marine ply!!! Most yachts have balsa cored decks - and teak looks pretty good on top as well.

In fact with modern epoxies wood is making a big comeback!!!
