dagger board vs keel
i want to convert my strider catamaran dagger board boat to a shallow long keel variety.
the wetted surface area of each board is .5x.5 meters, the whole boat weighs 1000kg.
i suggest two shallow keels, each 3.0m x 0.07m, i.e. same surface area as the daggers.
all your sugestions are most welcome.
