Hi Group. Could someone please tell me the thickness of the marine plywood required for the hull and deck of the Shearwater 17. I work in Cambodia and the full kit freight to here is quite expensive and am looking at buying the marine plywood locally, if it's available. My guess is that it's 3 or 4 mm. I realise that this info will be in the Construction Manual and Plans, but am keen to see if the plywood is available here before getting them. Thanks everyone.
