Most production boat builders who build boats with wood cores, use the squares instead of single sheet. As Strick alluded to, the reason is that each little square will adhere better...much more so than one large piece. Another advantage is that if you fully encapsulate each piece in resin, you are less likely to have water creep through the entire coring causing it to rot as is commonly the case with a single piece of wood coring.

Finally, the little pieces...mean less wood is thrown out as scrap....which can add up to a lot if you are building a couple of thousand boats a year.
