Thanks...it's my neighbors supra on lake wa and here's his blurb from last year:
"I bought a 2002 model year Supra. Awesome wake, PerfectPass, heater, shower, integrated ballast (1000 lbs), tower (w/ lights and speakers), dual battery. Some pictures here: http://www.supraboats.com
And here's a little info about how they tend to weight their boats down too:
You wanted to know what we're doing with all that lead you sold us. I've loaded 16 bars (about 900 lbs) into the back corner of the boat. I also have another 200 lbs of water ballast in the corner, with 600 lbs in the center of the boat. The result - a wake big enough to surf on.
P.S. Anyone wanting to purchase lead ballast for your boat - Fred will deliver to your home and has great prices: www.robbinsmetal.com
of course this is in the seattle area but i'm sure they could ship or suggest other places to get the lead bars.
it's a pretty sweet wave and my other neighbor has a mastercraft that's weighted similairly...they like to out do each other's wakes but there are other factors too...like speed, keeping the boat curved to the direction of the rider and everyone (including driver) on that side of the boat too.
