You can fabricate a keel out of wood. Use the Bombard Commando for inspiration.
In order to properly custom make a floorboard set for your boat, you will need to take some exact measurements of your particular boat.
The floorboard should be made to be at LEAST 55mm oversized from the total length, optimum is 65mm oversize, 75mm maximum.
- Inflate the boat to 240 mb and leave to settle for 4 hr
- Before measuring, check pressure and top off as ncessary
- Measure between the rear of the fixed floorboard (the thrustboard in the bow) and the transom where the stern floorboard section rests against it
The idea is the extra length stretches the boat out and locks the floorboards in place.
You will need some stringers that lock the floor in place and lock them from flexing up and down. They are triangle shaped blocks that fit over the floorboard "joints", and fit snug in between the joint for the tube / bottom of the boat.
