Hi
weight issues is of much importance for boat trailing in Europe , the data below is from my 312 excalibur 1980
The total boat weight is 3668 kg (mesured on trailer)
With 2 x7.4 mercruiser engines and merctrans tranny (=2x550kg)
With 2 axl trailer (=580kg)
Without 2 front seats (2x23kg)
Without exhausts (4x15kg)
Without TRS drives (2x63kg)
Without engine hatch 45kg
Without rear seats 40 kg
Without battery (2x22kg)
without the interior upholstery (all the cabin stuff)
without the toilet seat (13kg
without cabin closets and refrigerator (24kg)
without cords, anker (10kg)
The result is that this boat is the max in trailing weight 3500kg/ height / length (10meter) in europe , and it is the only 10 meter boat with 2 engines that legally can be trailed on european roads
I have read somewhere that the naked hull is around 1995kg. For my 312 excalibur , i think that is correct
