Hi,I purchased a 1998 H340 last fall and just recently found that the rub rail on the port side from the middle of the boat to the arch has pulled away about a 1/2 inch. I noticed some white calking in the crack so I am thinking it was a quick fix.I tried hitting it with a rubber hammer but it didn't work. It is very loose. Any suggestions on how to fix this? I had the boat professionally surveyed but he didn't spot this.I am now concerned that the port wall inside the stateroom which has a type of insulation material glued to it to maybe there to hide damage. Hope I am wrong.Ken
