I didn’t want the center board to be hanging on the uphaul line as I bounced down the road trailering Shackleton. So, I looked things over and decided to build a center board support to take the weight off the uphaul line.I took a left over piece of 3/4″ okoume plywood and made a few notch outs to better fit the trailer.Then I found some old leather I had laying around. I made a 6″ x 8″ cut out.This is approximately where I want the leather to fit over the wood.I used stainless bolts to secure the support to the back trailer cross member. I used fender washers for a good purchase. The notch outs allows to board to fit flat and rest on the trailer side member. I then screwed the leather to the top of the plywood support with smooth pan head screws.This photo shows the center board in the down, unweighted position, resting on the leather pad (I could have positioned the pad even further forward, but it picks up the center board just fine).
I plan to drop the center board down onto this pad when trailering with Shackleton. Note that even if I forget to raise the center board when launching Shackleton, the boat will still slide right off the trailer, as the board rest on top of the trailer cross member and butts up to the roller. Not a hard modification and makes me feel a lot better about the highway miles I’ll be traveling.
