1960 Whaler 13 project: "The Holey Whaler"

Postby Kenb » Fri Jan 10, 2025 12:02 am

I've started another whaler project, a 1960 13-footer my buddy anointed "The Holey Whaler".

THE GOOD
I found this boat in Marblehead. It came with a decent trailer, a period correct Evinrude 35-HP engine, and the original interior. The seller was in poor health, and he asked me to promise to do a good job on restoring the boat. Then he added a couple of tool boxes filled with good old tools, and that means I can't get too grumpy about what's under the hood

The topsides are in reasonably good shape. The original serial number (2415) is visible. There is crazing everywhere, but no stress cracks in the obvious places like the transom corners). I sold the engine to a guy who was happy to find one.

THE BAD
I flipped over the hull and found bad gelcoat cracks, which aremore serious than crazing. I knew some repair work had been done, but that work was pretty extensive. My [foiled] plan was to make sure the repairs were solid, then barrier coat everything, paint it, and flip it back over.

THE UGLY
Hitting the repaired areas with a rubber mallet shattered almost all of the repairs. They were too thin. Even worse, the foam under the repairs was wet. At this point, I realized that the sections of the bottom with the bad spidering might be wet too. I think the wet foam froze and flexed the gelcoat, cracking it. Lots of folks cut out the deck from the top and refoam that way, so no worries--except this bottom had huge sections that need to be replaced, so that won't work!

THE NEW PLAN
    -I started with the holesaw (which was in one of the tool boxes that came with the boat), and I found that not all the foam was wet, I'll get out the wet foam and pour in new foam in. Then replace the hole saw divots (I kept then).
    - Next I will apply two layers of 1708 [probably refers to a particular type of biaxial fiberglass cloth - yes, 17 oz cloth backed with mat, pretty standard boat building glass] over all the repaired sections.
    - Followed by [new allover topcoat paint using ...well... 545 primer/barrier coat THEN topcoat] AWLGRIP.
    - Some vinegar and salt to get the green off the old Norman pins.
    - I'm looking at a new Tohatsu-Mercury 25-HP engine with a 15-inch shaft and tilt-trim, and hydraulic steering. The new merc-hatsu is the first time you can get tilt/trim on a 15 inch shaft, and the hydrolic steering fits the curved transom. eg with hydraulic steering, there is no need to modify the 15-inch transom, or add extra parts.

In the meantime, it looks like I might lose a little bit of that famous Boston Whaler hook. (if you know, you know!)

No sane person would continue, but I did make a promise, and I do love old Boston Whaler boats.

The project should keep you busy for awhile. It's a heroic task you're taking on. Good luck.

You must like to spend a lot of time working in cold temperatures. I hope your sander has a really good dust management system with a HEPA filter at the vacuum.

Thanks for the comments! To answer the specific comments, questions:
- if by heroic you mean idiotic, then I agree!
- I made a stimson bowshed, gets to 55 with electric heat. 75 or 80 with Mr Heater. I double-walled the sides so it stays pretty warm.
- I tried the bosch hepa sander/vaccuum but returned it because on the curves of a boat hull, I wasn't getting enough suction to keep the dust down. For a few days, I was very confused as to why my 25 year old shopvac set up was working way better than the new $1500 kit... it was the stupid hepa filter! My setup is a shopvac with a cyclone filter, a hose on the outgoing air which vents outside, and a wen 3410 air cleaner thing. I also wear a regular 3m mask, too. I've used the festool stuff and its great, but not worth the price; not everyone has a bow shed! I recently discovered that the cheap electric leafblower I use for dust clean up also works as a leaf blower.

Anyway, first round of foam worked! Im going to try taping my divots in place and let the foam expand up to them. There seems to be a 10 minute period where the foam is hardening, but still pliable enough to move stuff around. If you don't get to the foam at the exact right moment, there's no going back. Also did some more glasswork!

Thanks to whomever updated and titled my figures! Im not sure how to do it for this post, but fig1 foam filled holes fig2 vinylester and 1708 for a handsome transom fig3 weekend progress!

Great project that should yield great satisfaction when complete. Thank you for keeping us updated and the pictures as there are many of us that are vicariously doing the work along side of you......
