Mini-Brig Project: Hull Construction - Step 5

 

Applying Resin:
 
Now that the internal seams have all been taped, and resin applied, it is a good time to flip the hull and tape the outside seams.
 
Apply epoxy and tape to the outside
Apply resin and tape to all the seams. Then coat the wood with resin.
 
Doublecoat:
 
After a quick light sanding we applied a second coat of resin over the seams and sides. You need to make sure that you apply tape and resin inside the daggerboard trunk.
 
Applying resin and tape over the seams
We applied a coat of polyurethane resin on all the outside seams and sides. 
Making sure we place tape over the daggerboard opening and seam.
 
After a quick light sanding we applied a second coat of resin over the seams and sides. You need to make sure that you apply tape and resin inside the daggerboard trunk.
 
We fibreglassed the daggerboard trunk through the opening. To get any rough edges and wrinkles we used a file to make sure we had a clean "edge" inside the trunk slot. We then applied several coats of resin to where the trunk mates with the hull and filled any gaps and/or imperfections so we had a "smooth" surface.
 
You may also want to form a small skeg in the stern, which can be at first caulked into place, and then a layer of tape and resin to hold it firm.

A small skeg at the stern of the boat: cut to size, caulk in place, and reinforce with tape and resin

We also applied several coats of resin on the bow, we applied  approximately five coats of resin. All-in-all we used about a gallon of resin, and about 18-20 yards of 4" fibreglass tape to cover all the seams.

Once the hull is fully covered in resin, before we can complete the finishing we will need to make sure that everything is properly attached.
