I have a similar problem on my HT, I havnt dealt with it yet as I will be bringing her round to west Wales in about 6-8 wks time where I will be putting her on the yard and doing a complete refit, paint and overhaul. I must say It looks very tight in the fwd starboard bulkhead so I cant say Ime looking forward to it, I may have to cut the access hatches larger to suit my girth lol, but I will do some pics and progress reports as I go. It looks like the water entered via the pulpit or stanchion fastenings. Sorry this doesnt help you now, atb Ken
