When building a cata-canoe, everyone suggests that the canoes should be lashed together with the bows "tow-in". It is said that this will enhance performance and decrease splashing between the hulls. I know that almost all cata-raft frames are built to hold the sponsons parallel to each other and that motors are only used on an occasional basis. So, I doubt anyone would go to all the effort to reconfigure their frame every time they started the motor. But, maybe someone motors their cata-raft A LOT, and uses it more like a sport-boat than a raft.
Has anyone ever experimented with building a frame for a dedicated motorized cata-raft and used a "toe-in" design?
If so, how did it work out for you? Any downside when drifting downstream and using the oars?
What kinda speed have ya'll been able to achieve with your motorized cata-rafts (either parrallel or tow-in)?
(please include your specific: raft model, engine model, approximate load, etc.)
