would the best way be:
to take the wave at a slight angle if your boat doesnt have the sufficient hull length to bridge the wave properly?
i suggest this as once the boat is lifted beyond its length, there is nothing at the back pushing the back of the boat upwards, only, (in rlni's case) two heavy engines at rear to weigh down the stern!
although there is the risk of rolling, a slight angle into tthe wave should be better i would have tyhought, depending on the steepness of the wave, as the toobs provide good lateral stability.
or....i think to push everyone forward, hold on tight as possible, tilt engine fully in, then at a slow speed ease the boat over the wave. it seems from the video that the main thing which caused the boat to capsize rather thann return to its normal position when it becomes airborne is that the whole boat looses contact with the water, and the forward motion, with the angle of the wave caused it to take off, so surely to apply slow forard motion would be best, to crawl over the wave, and maintain contact of hull and water.............
