I have a 24ft carvel boat. Has a lifting plate going through a long cast iron ballast keel and this is where the problem lies. I am having problems around the base of the lifting plate box inside the cabin. The wood is soaked and becoming damaged, thankfully it is seawater and the wood is iroko so damage minimal SO FAR!!! The boat is used in shallow water for very light sailing and I have to say have not used the lifting plate since I have had the boat. The boat has small iroko bilge keels. Can I remove the lifting plate and seal the hole in the cast iorn keel so removing the lifting plate housing in the cabin? This would mean the wood in this area would then be dry. I know my class of boat ( a Finesse) was produced without a lifting plate and with bilge keels. Is this going to be a major undertaking?
