Offshore Racing Boat - Best to build light weight or heavy?
MPM:
Ive had this chat with a few customers over the last few months about this...
light boats tend to jump over the chop.. Building an overhaul heavy boat makes the boat cut through the chop alot better because you have the weight in the boat... the kenetic energy has been loaded into that heavy boat keeping the boat prop in the water... jumping out the water you loose power.

Couldnt have said it better myself,also having your stinger slightly up from the keel line by quite some way keeps the transom planted which really helps,some have them exiting as near the keel as possible which can make the boat ride too high in the water in my experience but thats another subject lol.

If you ask 10 people you will get 7-8 dif answers.you gotta decide which bits of info will help you.Theres not always a right or wrong way to do things just different ways that will give you similar results but thats what makes it fun :} .If we all did things the same way life would be pretty boring so why not experiment and come to your own conclusioins ,you never know you might find a way of doing things that give you that edge over others.

light offshore looks bit silly when it gets choppy.
youl will never see a lightweight offshore boat in the real world.
too light and it will flip up back and over and also chinewalk like mad.
and dont forget to balance it both ways. left right and forwards backwards. centre of gravity for offshore needs to be
1/3rd of waterline from the rear of boat, not rear of anything over hanging..
I run my boat in the sea 60 inch boat and its around 15 to 18 pounds all up when tanks are full. if realy rough I might add a pound or 2
