I went from a 1983 Grady White (worth about 15-16 K )
to my brand new 2003 Parker (worth close to 60 k)
Same ins co, ins cost for new Parker went down about $100.00
Figure that one out!!!
Ins co told me , it's cheaper to insure a new boat than and older one!!!
My guess, an older boat can cause more liability!!!
leaking gas tanks, sinking, ect...
