Looking at an old thread it seems they were trying to match the 2 lbs density foam
used by the manufacture. One person used a hacksaw to put a gap between the top and
bottom of the foam then sprayed in medium density foam, not "Great Stuff." There is discussion
over whether the expanding...
It was something I picked up at Ace Hardware. The tub had holes in it
but you can easily reach it from the inspection port. The hull under the
tub is only supported on the outside edges. If you hear a "Brattttttttt. . ."
with the boat is planing out that's usually the cause. Push on the hull...
So why would yellow expanding foam in a can not work. It's just a more recent
development since the 2 part foam instructions were written. I've used in under
the cockpit to keep the hull from oil-canning. As for soaking up water the
original foam used by the manufacture has the water...
The chance of a mid 70's Sunfish not leaking is small to none. They were never
expected to be in service for so long. I just use a 50 cc syringe to suck the water
out after sailing. With both ports open the deck heats up in the Sun and convection drys
out the hull.
If the dagger board trunk was badly damaged you would peel up the front deck
to do repairs from the inside. You could use the Shore Line method to remove
the whole trunk but that's making twice, nay three times the work for no real gain. Once the
deck is popped you get to fix other things as...
When the bailer is in the boat it's rare anything works. Now that it's out of the boat
you have a chance. Soak the thing in PB Blaster for a week. Then put the plug end
in a vice. Heat the bailer for 30 sec and try turning it with a pipe wrench. I've had
real good luck using PB Blaster and...
A Sunfish in the weeds is music to my ears, it's
called a 'free' boat. That's how I got my last 3 Sunfish.
Tell the owner that it will take you $50 of you time and
gas to haul away a boat that can't be used. You'll do him
a solid and haul it away for free just this time. As boat people
Well give the seller your number and wait for a better
offer when they don't sell. You should be able to get
a no problem/no fix Sunfish and Trailer for $600. I get
small used trailers off craigslist for $150 - $200 range.
Spring is not a good time for boat buying anyway, fall is much
Just a different type of purchase. Offer $100 for the whole rig then strip the hardware and
throw the hardware in the corner of the shed for some future project. Spars/Mast/Bailer Cap
is worth that much. I have seen nice hulls for sale with no hardware, it's just one of those
You'll have to remove a bit of the foam block in the stern but that's not
a problem. You will not have to replace it and there is plenty left to
support the deck. The ports are well worth it and you can store your
lines and junk like keys and wallet in them. They far outweigh the
Well, thats the trick. Tapering slightly over the bottom lip of the transom
without destroying the lip. If the lip is ground away then you have to bend
the backing patch. Really does not look like you will have to go more than
just around the corner. You want the taper ground so your patch...
Grind down to the fiberglass so you can see the extent of the damage, i.e. grind off all gelcoat in damaged area till you have just clear fiberglass. If there are no spider webs/cracks in the fiberglass you may just have a sand/fill/re-gel coat project. I'm thinking I can see some...
Sunfish is not sandwich core but just woven roving and resin. Opposite side the backing plate
you'll bevel the 12% bonding area down to the hole edge. Each of you're 3 matt/cloth groups
will be bigger than the one under it so it will sort of be like building a inverted pyramid over
Not sure what you mean by exact patch. You have to grind away the gelcoat around the damaged area
to an area the is about 12 percent the total of the damaged area. The good thing about fiberglass is that
it's very easy to repair compared to other materials. Most of the time is spent sanding...
If the patch was put on with polyester resin you can remove it with a heat gun and a putty
knife. If that's not possible grind off the patch with a sanding disk. Cut around the edge of the damaged
area to clean up the edges. Put a inspection port on the deck and you can install a
