As an owner of that boat i would say around 15k. 12knots is dream. comfortable at 8-10. fuel is accurate . I run tour company with mine and I barely burn anything w/6 passengers 5 or 6 times a day. what size is the engine? weight is a factor with bigger diesels in those. I run a 4cyl westerbeke. if you dont buy it pm the owner I know someone looking for one.
