I am planning on building a plane that is towed behind a boat. Because
of the low speed (25mph stall) I am planning on using a high lift
airfoil. Some airfoils with high coefficients of lift a FX72150B
(2.0), FX73CL3(2.25), GOE225(1.9), GOE226(1.9), GOE234(2.0), GOE243
(2.0), GOE244(2.0), S1210(2.25), S1221(2.2), S1223(2.3), S1223RTL
(2.5). This is a link to the airfoils and polars:

I know some of these airfoils are for model airplanes and might not be
suitable. Some also have very thin trailing edges which may be hard to
build. I don't know very much about aerodynamics so I was wondering if
anyone has any opinions.

Popular Mechanics had plans for a tow behind biplane in the early 70's late
60's - fwiw...
