You can get newer 'less spendy' boats by using owner's time at the major players. We had done that a few times and were pleased. sometimes it is 30 to 50% off the regular charter fee.
Basically it is like renting someone's time share week at a resort. A lot of boat owners can't get down 4-6 weeks a year so they 'rent' out their time to you. You pay the owner directly but you are treated like any other charterer at the marina. A win-win for everyone.
