Just pulled the bow pulpit off the M17 in the yard. There is a soft spot in the deck just aft of one of the deck flanges connected to the pipes that make up the pulpit. After cleaning the bolt hole out I notice that there is about an eighth inch of space between the underside of the deck and the top of the v-berth liner. I don't think I am going to get all the rot out with a nail on a drill bit. Am I looking at cutting out the liner below decks or removing the deck and cracked gelcoat right over the soft spot? I plan on painting the deck anyway as there are lots of stress cracks and crazing in the gelcoat. Seems like it would be easier to open the problem from the deck side. Any advice would be appreciated. Thanks, Tom B. M-17#258, 1977
Hi Tom, I have the same issue with my deck. The approach used by the shop that is going to repair mine was to take a moisture meter and figure out how much the moisture/rot has spread. That way you have an idea how much balsa core to replace. The folks repairing mine are using Coosa Bluewater 26 to replace the Balsa but I am going to talk to them about just replacing it with Balsa in sheets. I am going to recoat my non skid so we are opening it from the deck side, not cabin side. Going from the cabin side means you have to hold the repair in place using supports which can be avoided by opening the deck side. A good reference is Don Caseys hull and deck repair book (I am paraphrasing the title). Robbin On 4/7/2014 5:00 PM, Thomas Buzzi wrote:

Thanks, Robbin. Don't much care to work with epoxy but going in from the top seems the easiest. I am lucky that is the only place I have found any rot. Got most of the wood and deck hardware off the hull today. Gotta use a mold bomb tomorrow though as the v-berth head liner has some bad looking stuff growing on it. fair winds, Tom B On Mon, Apr 7, 2014 at 6:20 PM, Robbin Roddewig <robbin.roddewig@verizon.net
