Mark, Leaks in the hull/deck joint are not uncommon. However, one must consider whether the leak is from under the rub rail due to excessive heeling and wave action or from water ingress through the deck/toe rail interface or from the fasteners. Don't think that because it doesn't leak except when sailing that the deck/toe rail interface isn't the source. The deck/toe rail interface may well leak as the boat flexes while sailing but does not leak while the boat is at rest.
Your solution may be correct with one very significant caveat. Tightening the bolts will compress the butyl sealant and sailing the boat may result in additional leakage. A few iterations of this may result in no sealant remaining. I tightened the bolts once when first got Touche' later deciding it may not be the best practice. Now I use multiple applications of Captain Tolley's Creeping Crack Cure along the deck/toe rail interface. Capt Tolley's "creeps" into the joint and cures forming a seal. I repeat applications every 2-3 years. While I may get some leakage due to extreme heeling, I'd be content to let that happen and either sponge out the compartments or drill limber holes to let the water drain to the bilge. Just my 2 cents worth. Dennis C.
