assume you haven't seen this, it's literally the truth.
Size of boat has a big impact on cost, I have heard 10% p.a of the purchase price is a rough figure, that holds true for me, but the majority of that is in marina fees. Getting close to moving onto the boat, then it will turn around because I will rent the house, retire and go sailing.
Saw another Meme on FB yesterday " Boats are like strippers, they stop working when you stop paying out the $100 bills"
