Evening all, The last few weekends have been spent re decking Simon Bone's 1763 as the rear decks have flattened out and cracked around the centrecases. The original [AJ] construction method was longitudinal stringers set into foam stations with ply only at the beams and centrecases. Over time the foam had compressed under the decks separating from the stringers/deck undersides/hull sides. The deck hull join was still intact but the deck was flexing downwards spreading at the foam /hullsides join.A trip up to Duck Flat Wooden Boats for 4mm Gaboon Marine ply/glass/ Bote Cote epoxy, rollers, and some expert advice. We routered the decks off and cut some ply stations [7 per hull] to add strength and ripped up some stringers from some cedar.The port hull was in better shape than starboard with the stringers [5] reasonably intact, the starboard stringers were all broken aft of the centrecase.Scribing in the 100 mm deep stringers to the hull sides/stringers was time consuming but essential. Today we fitted the decks with epoxy/ temporary stringers in what was reasonable temperature with the last couple of weekends being a less than ideal epoxy temp of 12 degrees, Cheers, Roy, 1770 Rebel Without a Clew
