Bristol? Sabre? Sabre? Bristo?
Both are vary well biult boats and the choice should be decieded by comparing what each has to offer in terms of layout and ease of handling. You should go to a marina near you and look for these boats, speak to the owners and ask what they think.
Heavier displacment = a more comfortable motion in a seaway were lighter displacment could = a more lively motion and more demanding atention to handling. Also a heavyer hull can take more weight on without sacrificing performance as much.
As far as Bristol v Saber I would take either of these boats offshore.
Using a Broker will help you find the vessel you are looking for much faster as they usually have a large listing nation wide.
Which ever way you go you must get a profesional survey of the boat of your dreams to protect you. The price you pay is the price you agree on the Broker is there only to help you, I know for one that it has helped me very much and I would definitely use one again. You could also consider chartering to see what you realy want v need.
Good luck and have fun!
