I rang David today but he's pretty tied up, so no chance to use his skill as a secret weapon.
It seems the hull and deck join on my Hartley is a problem area. So I'm exploring options to haul out sometime not yet for at least a week. I want to strip the gunwale beltings, toe rails and paint down to the first chine. Do whatever needs to be replaced/repaired and then fibreglass from gunwale to chine. With glass covering the hull and deck join. Just have to find a boatyard that won't require a mortgage and doesn't require days of sailing to get to. I'm talking to Boatworks but they want me to do all my sanding in a shed and that would mean pulling the mast out and I don't want to do that.
