Yesterday I went with Cathi out to buy a support boat. It's a 14 foot aluminum boat with a trolling motor. It looks to be in decent shape. I'm hoping that with this purchase that I can rely on my support team to not have to worry so much about rowing and steering with paddles.
I'll still keep the tandem kayak for shorter swims, but for those long swims, this new boat should do the trick. Especially for the Bear Lake swim. In fact, I'll have to try out the motor and see how long it lasts on a single battery charge. I may have to get another battery or two for that swim in July.
