[StartQuote] Found some interesting information on sea sleds including a proposal from Sep 1936 for a 57 ft sea sled six engine motor torpedo boat with three 18 torpedoes. Also, I believe I uncovered why there seems to be such extreme variation with the reported ability of the sea sled to handle rough seas. On the one hand we have significant designers, sea sled owners such as the owner of the magazine MotorBoating, and boat racers strongly supporting the sea keeping of the sea sled design, but we then have instances of the Navy saying how horrible they are. Two sea sleds that were tested and specifically evaluated by the Navy and mentioned as the reason not to buy sea sleds are the 32' crash boat in Pensacola 1916 and the 45' crash boat in Hampton, VA in 1935-6. Both of these vessels had extremely high beam to length ratios, in fact the highest (by a significant factor) from the 40 some models of large sea sleds I've been able to find information on. This would probably mean that the angle in the forward part of the vessels was probably way too shallow and would have had a significant role in increasing the slamming affect in any sort of chop. It seems that Hickman was trying to provide a very stable platform from which to facilitate personnel rescue for these crash boats. A narrower beam for the sea sled would have increased the hull angle at the point of entry and would have greatly helped the ride, just as this does for V bottom boats. A sea sled the navy was happy with, the C-378 motor torpedo boat that CAPT Mustin evaluated in 1918, had narrower beam, a greater hull angle and was felt to have great sea keeping capability despite the navy insisting on using overweight engines which greatly affected trim. CAPT Mustin employed light weight engines on the aircraft sea sleds C-1558 and C-1559. [EndQuote]
