Had a really good look at the MkII GT today. It is in good shape overall but the thrust board will need reattaching soon, not much of the keel tube is attached to the bottom anymore, and there are a few small warn spots that could use a patch. All items that can be fixed before next year.
Setting up the MkII is much easier than the C3. The intercommunicating valves are very nice to use compared to the three Boston valves on the C3, you only have to hook the pump up to one side or the other of the MkII and the whole boat is inflated to an even pressure. Each of the three valves on the C3 have to be pumped and it is a bit tricky to get the pressures even. Also the floor of the MkII is easy to install. The C3 flour is of the same basic design but the wooden keel makes it more difficult to set up.
I like the C3 but I'm used to the layout of the MkII because I've had a MkI for over 35 years and the wooden keel just might be too much of a pita for me, I'll be packing the boat down between uses and not putting it on a trailer.
Was going to put them on the water today but the wind has been blowing up to 60kph so that didn't seem like a good idea for a first time use of used boats and motor
