It's not that you don't loose,it's just that it's an acceptable tradeoff.In my installment on aft-body/boat tails I mentioned an "embryonic transom hull"attempted on a racing yacht.It was basically a truncated boat tail,as Kamm recommends for cars,but the design blew up in the boat-builders face.By chopping the tail off where they did,they were attempting to "prune the wetted area",the most significant aspect of a boats drag(friction drag).But the cut off created so much turbulence behind the transom,the rudder was rendered useless.They couldn't steer the boat! So it appears that for boats, there is a limit as to how much of the tail can be removed,before diminishing returns.Bear in mind that this was a racing yacht,built for the America's Cup,built for high-performance,with no pretense as to practicality if used as a pleasure yacht.
