Important Note: You need at least 4 of these gudgeons (2 pairs) To mount a rudder to a boat. We offer them singly or in pairs with the pin options shown below.
Above are three sets. The top example has a clevis pin and ring, the middle one has a quick-release pin and the bottom one has a bolt, washers and nut. Choose one of the options when ordering or just buy the gudgeons without pins. Keep in mind that you will need at least two pairs for a complete rudder installation.
Here are the general dimensions of this item:
The photo below shows the gudgeons in use on a kayak (my design) built in a high school student program on launching day.
Rudder made from 6mm ply with 4mm cheeks, and strongly supported by two pair of your gudgeon sets. I trimmed the tangs as you can see, but the whole set-up is much better supported than the often seen arrangement using a single pair.
These were our initial efforts (Wenonah Rendezvous and OT Penobscot canoes)
I’ve sailed the Penobscot off the NC coast and it works just fine, but it would be better with longer verticals on the control arm to help stiffen the oversized canoe rudder. I came in against a new moon outgoing tide (bad timing) with the sail up, the rudder down and a 10 mph tailwind and what would have been a tough slog was mostly a sit and foot steer.
We are going to try to approximate the Dr. Suess shape of the rudder control arm on the Kruger Sea Wind to enhance the stability of the that massive DIY rudder.
It’s a work in progress, but we’re getting there.
An easily removable drop in and pin rudder assembly on a canoe would be a godsend, especially when paddling in the wind or when sailing.
