You're right, you need pro advice
Small sails won't do much to either get you home or save fuel
and probably the hull
won't be happy with big sails. A 100% foresail and the mizzen will not be very big and to get anything out of it you'll need to put a mainsail
with a boom on it.
Issues to resolve:
Where to put a boom? The high bimini
(plus your head) will limit the position of the boom and size of any mainsail
What is the underbody of the vessel? Probably there is no keel
to speak of, and rudder(s) probably small. So sailing might be problematic.
I recommend getting drawings of the hull/keel/rudder plus of course the house structures and asking an experienced naval architect to design you a sail plan, then ask a sailmaker/rigger to build and install it, but don't expect it to do much or be cheap
Sailing is a sport, an athletic activity, not a sedentary one.
