landfills will take them, but if they are whole then they will likely charge you a bulldozer charge, its around $100 in this area. So when I throuhg away and old power boat that I needed the trailer from I used a sawzall to cut it into pices, load it into the back of my truck, then i was able to drive it out to the landfill and dump it for the normal $10 fee. A sawzall will make VERY short work of a catamaran hull, so this is deffinately worth it in my book.

Incedentily, what type of boat are you parting?
