I dont think you are going to get many ribs at 45 knots in diesel with a 45k budget, your going to have to pay more , anyway running at 45knots in the alantic , i think you body will give up the abuse after 1hr anyway , unless you go redbay 11m with airsupenssion seats . they have a top speed of 42knots and cruise at 30-35knots, but dubble your budget, and you wont be close to paying for one of these amazing Ribs, !!!!!!
Bravo 3 or 3 X's are a ticking time bomb in a rib , to be avoided at all costs !!!!!!
GO to the redbay Boat yard its is bloody amazing
