We are looking at 2 different 18Ft. I/O bowriders.<br />One weighs 1950lbs. and the other 2600lbs.<br />Our family weighs 600lbs.<br />If we bring freinds add another 600lbs.<br />Will we be able to ski with the 3.0 with both families in the boat or will we need the 4.3?<br />Would the 3.0 perform well enough with just one famliy?<br />The manufacturer of the heavier boat says its all in the hull design.I can't beleive anybody really has an advantage in hulls.They all claim to have the best design!! All opionions would be apreciated.<br />Note most skiers will be under 150lbs.<br />Also how about tubing.<br />Thank you
