I use Force Fins in my 9 foot Water Skeeter and can spin round and round in place. My boat does have a rocker design to the pontoons but I don't think that makes much difference. I think the short V shape of the Force Fins makes them more suited to maneuvering than the longer scuba fins. They cost a little more but are well worth it in my opinion. Get a Versa Vessel and some Force Fins and you will be a happy kickboater. :-)
