I have a continuing leak problem on the portside of my Mistral. I have redone the Sikaflex throughout, reseated the stanchions, checked everything possible, had various experts investigate, but still it persists. The charttable and quarter berth get wet in either a) heavy rainfall or b) we're beating on starboard tack and heeled over so the port toerail is close to or on the water line. I must be missing something - any ideas ?
