The ride will depend on the props for sure. I have had a lot of luck with labbed props but even that will depend on who did them. I have tried Throttle Up, Mercury, and BBlades all the same pitch and different results. You can expect some bow lift out of the whole unless you use the tabs The tanks are two 70 gallon like many said. I would take the sonic all day over the 311 sr1. The cabin and finish is much better. Just look at the wiring on each and you can see a big difference. You will be very happy with the Sonic but don't expect to be the fastest unless you are in some nice chop. The 31 crushes waves and is loads of fun when everyone else turns back.

I looked at one here in ohio and liked it but found my self likeing the 33 more butn was still a grate boat.

Thanks for the advice. I had a 311 in the past. Cant really compare them totally different boats. I was surprised with how big the 31 was for a 31 with an integrated platform.

How did things go with the 31 you looked at ?
