The difference in "de-motion" between sail and
trawler is elevation. On our 49 DeFever sitting in the PH my
head is 13 ft above sea level. We removed our FB which added another 7 or 8 ft (nose bleed elevation). Never been sea sick sailors have felt the worm turn while onboard in aft quarting seas with paravanes deployed because of the difference in elevation. Would advise some form of stablization for extended nearshore cruising,
bahamas. I think the mainships have high hp eng or engs., but you can get a KK with lugger (JD) run at 1500
RPM do 5.5 knots burning 1.50 gal /hr. More than your sailbote but a
fuel sipper for a powerboat. Most
single eng prop shafts are parallel to the
water surface and are more efficient than twin eng slanted shafts which helps a lot. I am not real fond of the GBs no flare plumb bow, I've seen them bury instead of riding up and over. Good luck
