Add Strength to the Transom  The hulls transom holds many driveline parts including the rudder, drive strut, turn fins and trim tabs. All of this hardware needs a solid mounting surface to mount on to. This surface must also bee strong since a majority of the load will be placed on this part.
The best way to get this strength is before joining your hull together. First make a paper or cardboard template of the transom shape. After getting the paper cutout to fit properly in the boat transfer the outline on to a piece of 3/32 or 1/16 inch plywood.
Once I have the plywood fitting well I coat both sides and all the edges with a spit coat of epoxy. The epoxy serves two purposes, first it helps to water proof the wood and prevent it from rotting, second it adds additional strength to the wood. Once the epoxy has cured you can either CA or epoxy it to the inside of the transom (see picture). After all the glue has dried you can join your hull pieces and mount your hardware. |
