Right now the biggest difference between a SVL and a SS is money. A good used SS boat will run you about 100,000-150,000 where as an SVL can be bought for 75,000 , I would say you can race either of these boats for about $5,000.00 per race including all expenses. The biggest difference is the up keep. On an SVL you change the oil in the motor and drive then rebuild the drive. On the SS you need to rebuild both powerheads at least once a year which cost about 8-10 grand to do it right plus rebuilding the gearcases for a couple more. I would LOVE to have more SS boats but believe someone would be better off getting some cat time or race time in something else before racing a cat. Being a competitive SVL ain't no cake walk either.....no matter what class you choose there is a bunch of people at the races that will help you out and get you going. It is the greatest sport around on and off the race course. No matter what you do or where you race be safe and have fun.
