Sailed today. Less than 10 knots of breeze, most of the deep reefed main wasn't working due to halyard slippage and or lack of boom snotter tension, top speed 6 knots.  Nothing cracked, creaked or groaned,  steered well, shunted easily and turns on a dime with both rudders.  The bow stays up, at one stage was lifting, giving hope for planing.  

Everything worked apart from the tiller extensions which have to be twisted as well as flipped (eventually broke one of them), because the rotation axis is horizontal instead of vertical (silly of me,) the main halyard or telescoping line which slipped and all the temporary strings and attachments which now need to be made permanent.  Also need some more purchases on the control lines.  

The sail lashings to the mast, stub mast and beam mounted rudders all work well enough to continue with them.  

All in all, it was closer to my wildest dreams than it was to my worst nightmare, but still a way to go to be the boat in the video.  

Pictures and videos on  builders blog and Facebook tomorrow.
