Last year when the boat was out of the water
for it's yearly antifoul job I noticed a slight leak from the garboard plank and appeared to be patched some years back before I had the boat - it was patched with a peice of wood 3 feet long, 1 inch with and 1/4 inch thick. This year I removed the old wood dried the wood with a heat gun the filled it with sikaflex 291 and a capenter screwed a peice of wood slightly thicker than the one aforementioned.
The boat now leaks
worse than ever - bilge
kicks in every 48 hours
Any ideas what went wrong and what can I do to rectify - I am prepaired to slip the boat again if I have to - PLEASE HELP
Boat is a wooden hull
28 foot long built in 1951 and is in pretty good shape
