“Dan Leech was chosen to undertake the design work for our OK dinghy update programme. This was a twofold programme of both update of the existing design and also producing plans and cut files to enable plywood kit set construction.

Dan’s knowledge of small yacht design and performance allowed us to quickly identify the areas where small gains could be made in performance which he seamlessly incorporated into the new design, and his back ground in boat building together with his naval architecture skills meant his eye for the details of the kit set boat construction meant every small detail for ease of construction was taken care of.

Once constructed, the first 3 boats delivered the expected performance gains with them taking 1st, 2nd and 3rd places in one of the highly competitive New Zealand raking regattas, and two of the boats going on to take 1st and 2nd place at the 2014 worlds and 3rd place at the 2017 worlds to also go with 4 New Zealand titles so far.

Dan’s talents as a national champion winning sailor, boat builder and naval architect, along with his enthusiasm for boating in general make him the new generation of top draw New Zealand designer and we have since commissioned Leech Boats to undertake the re design work on our 40ft performance cruiser of which the work so far has been top notch”.
