It depends...

Solid fibreglass with sprayed on chopped strand mat is a far inferior construction material than plywood. However if the boat is heavy enough it probably doesn't matter that much. Few dinghies are that heavy though.

Foam sandwich with reasonably quality glass or better is superior to plywood if the materials are used correctly. However quite a few class rules make it very difficult to use the materials to best advantage, and for those classes wood will probably still be better.

Again it depends on the class - some classes seem to be faster in wood.

In the Contender the jury is out over whether the all wood Bonezzis are faster than the composite or all glass boats.

For looks the Bonezzi wins hands down - those of you at the dinghy show will know that.

In Merlin Rockets plastic and wood are equally quick, which is precisely what the rules are intended to achieve. Wood for new designs (it is a development class after all), plastic to allow low-maintenance copies for those who want it.

I know less about Solos, but from what I've heard plastic and wood perform much the same there too.

In scorps plasic and wood compete on equal terms but wood stays competitive for far longer hence why most the fleet have wooden boats

it does depend on the classes and the exact materials used. In cadets it is thought that wood is faster but it is not known why, tho some of the wooden and lastic boats have different designsfor example the boyancy tanks are in different places.

Some classes were designed to be made from plywood, for instance the Wayfarer and Scorpion.  The chances are that boats in that class made from wood will be faster.  Other boats are designed to be made from fibre glass and are difficult to make any other way ie Laser - notice the round bilges.  There are a few classes that were designed to be made were the laminations of wood are formed in a mould.  They look beautifull in wood but can be expensive and their shape makes it easy to also mould in fibre glass - there's probably not much difference in perfomance - just maintenance; Fireflys, Albacors and that beautiful Contender fall in this category.  Then there's a question of resin.  Epoxy is more expensive but better in many ways, and then there's the type of fibre, glass is cheap but not as strong as carbon, kevlar and others. 

So like everything in engineering its a compromise between price and performance.
