If they can make a car go 70mph with an electric motor, why not an
electric motor asist for large yachts,(50-60 ft) run off batteries
that are charged off a solar array situated on the canopy.

Seems like any assist would be worth while considering large yachts go
thru 1000's of gallons of fuel.

If you want a yacht assist that runs off of solar power, the cheapest,
best tried and true method is called sails.

I thought sails used wind.

Wind is solar energy, it's the product of the sun heating air.

Given that the sun puts down about 800 watts /m2 (1HP/sq yd of surface
area) there's plenty of power "available" & it can keep the wind blowing
even when in darkness, because of the aggregate huge amounts of energy
that are deposited every 24 hrs.
