Put together a few clips showing the boat moving along. We were taking it very carefully in case it exploded/fell apart/sank/whatever as it was stupidly cold and we are hopeless.
Shallow water so we could mostly have walked back in but that made it really painful as we couldn't get the daggerboard down and coming back in we had almost no rudder and centreboard and with the strong current wanting to drag us out into the channel t was tedious in the extreme.
We felt it went very well and it proves the basic dimensions are about right. I will make the next float slightly deeper at the back and slightly shorter I think. I will also extend the front vertical support to the float by a few inches as I think the balance isn't quite right.
Once all sorted and able to sail for the summer I will then get on with replacing the main hull with a similar size/shape but designed to be a trimarna from the outset although it will alos be sailable as a true dinghy as well with just some extension wings for hiking/trapezing if we want to.
I've uploaded a video to youtube, link here: https://www.youtube.com/watch?v=y79a5qejTFY
so you can see how it goes.
We probably won't get out for a while now, but hopefully we will take the trapeze harness and give it more of a thrashing.
