Boat Weight & Performance Curves
Posted: Sat Jul 14, 2018 6:38 am
Something to consider:
The published dry boat weight for a 10 meter is 12,000 lbs.
That's the number I used when we calculated the first set of props for the new diesel engines in 2005
Those diesels are a bit lighter than the 454 Crusaders they replaced
Filled the boat with 242 gallons of fuel, 17 gallons of genny tank fuel and 40 gallons of water for her first test run with those diesels, and loaded her back with all the tools, spares, dishes, etc.
Put her on the travelift - SURPRISE - SHE WEIGHS IN AT nearly 18,000 lbs !!!!!
It is my own guess that the published dry weight is for the base boat, with zero options.
Once you add in the generator, additional sound insulation, wetbar, the L bench seat, the aft bench seat, windlass, microwave, anchor, anchor chain, tools, spares, icemaker, refrigerator, has grill, full fridges of drinks, sodas, beer, and other assorted stuff you get to that actual travellift weight.
My point here is that the performance claims are likely made for naked boats, with little or no options low fuel and probably one operator on board.
In this case even after adding in a full tank of fuel and water, the additional weight is well over 20% of the original published number.
Bottom line - one cannot expect to attain factory performance numbers with a heavily optioned boat.
