|sailaway21||Hull speed and hull design mean far more than displacement. For instance: 30,000SHP is sufficient to push your 1000' containership along at something over 20 knots, while it takes upwards of 120,000SHP, and another screw, to push the same vessel at speeds over 30 knots. Speed costs money, how fast do you want to go?|

|sailingdog||LOL.... would seem that TB's a bit sensitive about his motorsailor's sailing abilities... BTW, I never said it didn't sail well... just that it was a motorsailor.|

"Best-built motorsailer in the world" they say.

If the original question was speed through the water then current is irrelevant. (not counting the waves of course) If you just had a knot meter and no way of seeing land, the stars and no GPS, only your hand dragging through the water you would have no idea there even was a current. Now speed across the ground, current would matter but it is still a performance question. Same as a aircraft through the air....

|sailingdog||That's why your boat is considered a motorsailor...not a true sailboat...|

|sailingdog||There are way too many variables... engine size, gearing, prop diameter and pitch, hull design, etc. The best resource would be something like Dave Gerr's The Propellor Handbook.|
