Hi Eric, the boat is running at its fully surfaced trim , having the model ballasted higher in the water as per the tv programme , well the boat just rolls over, the model has a small worlds gas wtc with twin motors, the model has a tendancy to stand on its nose as power is increased this is caused by the manta fins and hull form at the bow, a reduction in speed and full up on rear planes cure,s this , because of the triple rudder, the boat tends to lean in the turn, underwater this is a quick boat, there are forward planes marked on the manta fins but i havent used them , i tried to use the fairwater planes on the sail but again if your tearing along they work otherwise at normal speed the effect is nominal, ive added a couple of pics of the larger seaview currently waiting for its 3rd rebuild the de boer seaview has given me alot of pointers on how to improve the hull.
