    It depends. If it is overloaded enough, the maximum speed is 0.00 knots, at equilibrium.

    00.0 knots of course with no wind.

    Does the hull speed s/l ratio work for a long slender hull. My longest canoe is faster than my shortest kayak. Can they beat 8 knots in a 16knot wind with a 200 sqft sail

    Your posts are way too cryptic.

    However I think you are saying, can a beach cat sail at 8 knots in 16 knots of wind

    yes of course it can!! Check out some youtube videos for proof

    Why are you asking

    Why do both hulls in the water mean it is overloaded?

    cat hulls

    My old ama were canoes. Lightly loaded they would almost plane. Top speed was 10 mph. However loaded to the point of drafting 4" in the same wind top speed was maybe 4 mph. I am thinking a cat hull would still hold to a higher speed. When loaded with camping gear.

    I looked at your gallery photos. Clearly you would have a faster, more manouverable and much safer boat if you had a real catamaran or trimaran instead of two open canoes lashed together

    is that what you were asking?

    I've noticed on a medium/light wind day, the 81' Hobie 16 I sail had this little bit of a speed hump around 6 or 7 mph, so for a regular beach cat, the more you load it up, the more its going to be affected by the hull-speed bump. For canoes, I would look at it as two individual canoes that happen to be sailing next to each other.
