17' Boston Whaler "Blown bottom" project
I was given this 17' Whaler last week. 15' & 17' Whalers are very popular up here. I have two people that want it when it's done and will pay $4,000.00 for just the hull. I decided to take pictures and post to show how easy this "junk pile boat" will be to repair and make a nice profit to boot!!.
I REALLY want this one done and sold in two weeks.I'll be spending 2-3 hours per evening on this project.
A few bad repairs by the owner came off and the water pressure tore out what you can see here and delaminated the other side about the same area that's missing plus the whole keel area. I drilled 25 holes and syringed in 10 pints of foaming polyurethane glue (Gorilla glue type). After that I bought some
empty caulking tubes and pumped in 1 1/2 gallons of West Systems epoxy through
the holes to fill the voids the glue didn't fill. I had to make some saw cuts in a couple
areas to get the fiberglass to "relax" as it was bulged slightly. These pictures were
taken after two evenings work. You can see the glue and epoxy where it oozed out
of the delaminated areas. Tonight I'll spray foam the voids and over the weekend
shape the foam and bevel back the edges of the repair area and start laying it back
up. I think I'll add a pad to the last 4' to see if it helps lift and stabilize the hull. More to come.

#5 This is the front corner where the rubrail attaches. Like the snazzy paint job?? Thank goodness 90% of it is flaked off. A putty knife scrapes it off easily. See the old repairs?? Nasty!!! The surface wasn't ground so the old patches just peel off with a putty knife. Saves on grinding!!

Interesting project...
maybe you'll be alot better at estimating time to complete projects than I am...if I think 2-3 hrs per day for two weeks is enough I just multiply by 2 and I start getting close...

Well Reese, you're a fellow "glass man" and I DO know how prodjects run "over". I do several Whaler jobs per year and am pretty good (and fast) at putting these back together. I'll get photo's on Monday to show what was done over the weekend.
BTW, I will be foaming over the epoxy "drizzles" so the resin won't be on top (which we all know is a "no-no")
I layed these decks up in 4 hours. (The first one took 6 hours) The more you do ,... the faster you get.

Very nice, more project than I would have taken on, lots of damage. The funny part is that the whaler's are tough boats. Thats alot of damage. Carless drive I would guess.

Put in 4 hours today. Got it layed up!! I used a combination of resin, chopped glass, milled fibers, cabosil, and microballoons to make a putty. I spread this over the exposed foam to bring it up to the level of the underside of the boats origional fiberglass. I then laid two layers of mat, a cloth and two more layers of mat. I got the front corner foamed and puttied and will lay it up Monday. Tomorrow is family day (Sunday) so I HAVE to take the day off. More to come..................

On the picture above you can see a piece of stainless I screwed to each end of the damaged outer sponson right at the ridge. By squishing the putty up to the edge then removing it, you create a straight edge to work off of. I did this to the lifting strake corner as well. This saved time on "eyeballing" and having to spend more time sanding.

I took a few minutes and laid up a wear strip down the keel and out to the edges of the lifting strakes. (great place to cut a clean edge) I used two layers of mat, a woven roving, and a double bias. These Whalers take 4 wheelers to logging roads on nearby islands. The beaches are sharp rocks and a wear strip is a must.
