I was browsing TORC's website the other day and found this...
MiniCat
Ages 9+
Similar to above but using 15hp stock motors. Driver must be between 9 and 15 and the co-pilot has to be over 9.I believe the idea was to use a small aquarius boat?
Anyways, I bought a cheap Saturn 9'6" Mini Cat in the summer as a tender for our old Chris Craft cruiser.
The boat costs about $600 plus shipping brand new. I am very impressed with the quality of these boats! We run a 9.9 Johnson on it and it runs just over 20mph. We tried a Merc 15 on it as well. When running solo, I just about flipped it over! LOL! I actually had to sit on the opposite side of the boat to counter torque steer. With myself and one kid, it was perfect. We ran 26mph with a stock 9p prop. It doesn't have high jackers and rides on a running surface glued to the tubes. It rolls up easily and fits in a bag that comes with it. I wish I had a picture of us running it, but Here is a picture I found online.
This might be a super cheap junior Thundercat Class! With a boat and motor that fits in your trunk! If not, I thought you guys might like the info if you are shopping for a dinghy.
