« Part 3: Planing the Gunnels Part 4 of Building a KARA Hummer Layout Duck Boat series Part 5: Fitting the Plywood Hull Panels »


An option during the build is to install anchor pole through-hull brackets. Anchor poles are pushed through the hull and into the marsh bottom to hold the layout boat in place in shallow water. I figured that if one was good, two would be even better to hold the bow and stern in place during crosswind set-ups of a decoy spread. Anchor poles are quicker and won’t get snagged in decoy lines like a regular anchor and line could.

I installed braces of 8/4 stock, leftover from my nose pieces, between the keel and the main deck support; carefully matching the shape and ensuring the braces were perpendicular to the waterline. I used screws and epoxy to fasten them.

These brackets are fabricated from leftover 5/4 stock and 1 1/2” PVC pipe.

Batch Production

I used a batch production to make the four brackets. It was safer drilling 2” holes in a board that was 15” long rather than a 3 1/2” long board.

I marked all the cuts to avoid confusion during boring.

Boring the 2” holes.

Boring the 1/4” holes for the bolts that hold the bracket in place.

Ripping the brackets in half.

Boring holes for the lower bracket. NOTE: The extra deck ribs hindered drilling the upper bracket holes. I will install the brackets on the brace before gluing the brace into the frame on the next two boats!

I used the PVC pipe as an alignment guide to be sure the upper and lower brackets were aligned to each other.

The outer diameter of the pipe was 1 7/8” and the hole saw was 2”, so I used some leftover UHMW material as a shim to ensure the bracket would tighten evenly around the pipe.

I’ll apply epoxy between the bracket and the brace to keep it in place.

NOTE: I’ll show my sealing strategy to avoid leaks through the hull when I get to that stage in the build.

In the next installment I’ll start to apply plywood to the hull.
