My other sailboat is a Hobie. It has a similar glass/foam/glass sandwich construction. Hobie's tend to delaminate in an area (right in front of the pylons) that is structurally important. So it is necessary to fix delam in that area.

This is a very bad idea, unless you like smoke and fire. Most computer
fans are DC fans, especially the ones with "funny plugs." Never plug a
DC motor into an AC line.

Yes that would work. The sum of the forces (weight) equals the total
weight. It's a simple physics problem.
The only caveats are that the error in the measurements is also additive,
and that you need to subtract the weight of the other objects (wood
blocks in this case)...
What about MarineTex epoxy putty? This would seem to be an ideal application for it.

I have never tried it. Any experiences pro or con?
There are a number of threads that discuss applying epoxy to fair the
daggerboard. Search for "laser blade repair".
If the shape is correct, I think you could just paint it.
Has anyone tried using epoxy appliance paint for this? Seems like it would
be ideal.
Changes I'd like to see...anything that makes it faster/easier to rig and de-rig.
It takes time to assemble the parts and tie all those knots.
The laser is better than most, but I'd like to get out on the water faster.
I thought I'd pass along some advice from the Hobie Cat forum:
If you're ever shooting gelcoat, I found the homeowners secret. For $9.99 at Kragen auto you can buy a cheap touch up gun that shoots gel pefectly!! If the pot hardens, toss it and go get another one. It's way better than thrashing...
Since the laser was invented in 1970, any patent for it must have expired many years ago. Patents are only good for 20 years (in the US and most WTO countries).

We could have a much better rudder.
My other boat is a Hobie 16. It has EPO rudders. AIUI these are foam core with
an outer epoxy-fiberglass layer. They are stiff and won't melt in your car. The
rudders for the H16 are larger than the laser rudder, and they cost $250.
The easy solution...
I recently did a similar job replacing the metal mainsheet strap with plastic.
I used a large (1/4" or 3/8") cobalt drill bit and cutting fluid. I went to a
specialty tools store to get the cutting fluid (Rapid Tap).
Given that you broke a drill bit, try using a larger sized one at least 1/4".
Gouv: What problem(s) are you trying to solve? If you have some specific gripes, others can propose solutions.
Incremental improvements are generally preferred to more extensive improvements. Lower risk. Easier and faster to implement.
The suggested springs sound to me like an excellent...
That hole looks very similar to one I recently fixed in the deck of my boat.
Have a look. I got lots of helpful advice on this thread and there are
photos.

I just finished a repair with West epoxy. I think it is probably the best
way to go for your repair.
As Geoff said, you can vary the viscosity by adding (or not) filler. More
filler makes the resin more viscous (thicker). You can adjust its density
trading off weight vs strength by the...
