At those speeds you still have a hell of a lot of aerodynamic drag. I seem to recall increasing speed from 60mph - 75mph (25% increase) Aero drag increases 56%, 70mph - 75mph (7% increase)aero drag increases 14%. If you can reduce speed to 55-60 you should see big benefits. Next thing is to reduce gross weight, remove unnecessary junk from RV and sailbox. Good vehicle maintenance goes without saying.

What do you mean by "unnecessary junk"? <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> Your junk may be our treasure, and we have a lot of junk and we never know when it might become "necessary."
To me, the "unnecessary" junk in the RV includes the bed, the couch, the chair, the TV, the stove, the refrigerator, and that stupid washer-dryer. If we got rid of all that, we would have a lot more room for sailing junk. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
