Kelly Peterson 44 Refit

Hey guys,

My girlfriend and me have bought a Kelly Peterson 44 last August with which we intend to go cruising. She currently sits in Cabrales Boatyard in Mexico, where we'll do the refit from approx. next January on. We're both refit noobs, so there will be a lot to learn.

We'll most likely have a million questions along the way, so I thought it would sense to just open a thread to post them all instead of spamming the forum.

First question:
When the boat was pressure washed, a big brownish spot around the sink thruhull and the raw water intake of the engine appeared, which was not there when surveying the boat last year. Looks like the (very) old antifouling has been eaten away by sth. Also the SSB anode that sits in the same spot looks pretty beaten.

Since we're most likely going to peel due to Osmosis issues, I was looking into youtube and I found a video of someone peeling his hull with the same issue (well visible in the thumbnail or from 1:44 on).


A shot of our hull:


Does anyone have a clue what that could be? We have a couple of theories (years of stuff going down the sink, bad prep work before anitfouling, stray current etc.) but I wanted to ask around anyway.

Thanks for any hints!

Re: Kelly Peterson 44 Refit

It was there while the boat was in the water, and it originated at the through hull closer to the keel. What came out of that one? Gentle sanding is going to reveal whether there is damage to the hull, but it doesn't look like it.

The peeling of all the gelcoat seems rather drastic. If you've got blisters, the usual route is to sand out each one individually and then refill the depression with either gelcoat or if very deep cloth.

You've got a very big job ahead of you - refits have a way of expanding to twice the available time and money. Consider not making the job worse than it has to be.

Good luck, and do post your progress.

That's the the thruhull of the sink, where all the stuff from the galley goes through. It wasn't there a year ago when we did the haul-out for the survey. It's two layers of black Antifouling that look bad. Below is a layer of blue Antifouling that looks fine. There's some small parts that have chipped off to Fibreglass, which looks like its in very good condition.

We've got a ton of really small Osmosis blisters going on, adding to that the gelcoat above the waterline seems to be crazed. Overall, the entire boat is in desperate need of a new paintjob. We'll try to sand everywhere first of course, to see how bad it is.

Well aware, we're hoping for the best.
