you will need a one piece board to go from the transom up to where the thrust board was ,,,do away with it altogether .or to where the bow starts to rise and then you can either make another bow board to go from the main board right up into the top corner of the bow or make a smaller triangular bow board to go right into the bow end and then use bottle screws to make it ridgid ,,,,as long as you round off the edges of the boards where they touch the rubber you shouldent have any problems ,, as you said ,,in replacing the thrust board with a one piece the engine thrust is distributed into the bow,, and the inflatable keels upward thrust is just about distrubuted throughout the one piece floorboard unlike the original thrust board system where it is nearly all taken on the fabric flaps,,only problem with either system is its best to leave the boat inflated ,,,well ,easier .,,,instead of bottle screws you could make a couple of pieces of wood slotted or forked at each end, to fit the main board and bow board ,locate them at an angle then tap them tight into position .,,good luck mart
