Take a look at the wood locating diagrams here:

The hull itself should weigh about 320 and weighing it is the best way to find out if the foam has water in it (there are no stringers as Matt says, just wood in the transom and in various locations to facilitate better fastening). A quick way to check is to try and lift a corner of the boat. If it feels super heavy, it could well be waterlogged.
