To buy the boat you are looking at over 150k For a used boat. Brand new, over 200k. Fuel is 350+ to fill the tank depending on if you fill at a gas station while traillering or if you fill at a marina. As for speed, maybe about 40mph full out. These boats are purpose built for water sports with bladders that fill with water to help with making big wakes for wakeboarding and wakesurfing. I wouldn’t use it for fishing, the interiors are pretty nice, getting fish slime all over and dirt from worms and bait would trash it pretty fast. Lots of things to damage and break as well. You can probably charge big $$$ to rent it but you would need big $$$ for security and damage deposit. They are expensive to run and own.
