Replacing the Hog
Prior to fitting the new hog I had twice run warm epoxy into the area of the hog / hull join to ensure any unseen damage was thoroughly glued back together.
The rest was quiet an easy job. I bought a piece of Utile pre cut to width, and the maximum depth it would need to go to. I then cut the slot out, and shaped the underside to the angle of the hull. I then screwed through from the bottom of the boat to the forward piece, and clamped the parts I could get access to. I used lots of epoxy to ensure there were no air gaps. Finished result:
A couple of days later (after lots of boring varnish removing and sanding )I put a small fillet down each side of the hog for added strength.
