..somehow 'glad' to hear some else has recognised the same problem as well.
Most prof's will tell you to fine-tune things like weight, engine height, cav fin's etc. But with this problem on your hands, those things will only do jack & shit.
Now; to further adress to the problem of a 'overstretched hull'
My progress so far;
I proceeded with lengtening the 'thrustboard', by adding more pieces of wood, adjusting them to fit the rest of the floor. To counter these adjusments, I also had to alter the shape of the forward-thrustboard, (small one,which lies in front of the big thrustboard)
For most inflatables, I think this might very well do the trick.
However, due to both the (awkward) design of this vessel and the intensity of the stretched hull, adjusting the floor alone won't do the job.
To make up for the stretch I tested and finally glued some length of rubber (the black stuff) to the hypalon floor in the exact center of the floor near the transom.
The other place I glued some, is the section just in front of the 'point where the V-shaped floorboards meet'. (see my previous postings&photo to explain) Fully inflated, the floor-tube will push the hull down on this point, avoiding getting myself a stepped-hull-the-wrong-way.
Flipping the boat and looking at the hull, tells me I might have succeeded at this point.
Getting the boat appart everytime to alter the floor is certainly wreaking havoc on one's spare time, so the afore mentioned improvements are yet to be tested....
Next up; mounting some 60 angry horses on the transom and see how it works... will post the results, hopefully next weekend.
