No problem. I assume you're coming from the north. If so, take 24 south through Tiverton into Portsmouth, and then follow the signs for 114 South ('west main road' in local parlance, but not labeled as such). After going up the hill from the exit ramp, keep your eyes open for Dunkin' Donuts; take a right at that light (there will also be a gas station and package store at that intersection). You'll go maybe a mile, heading towards the Melville marina area; as you come down the hill and it curves to the right, take a left. This is 'Burma road' or the Defense highway. Weaver cove is maybe a mile on the right. Lots of parking, fairly new ramp in great shape (near as I can tell).
