Hi Dave,
Welcome to the group.
I don't know of any kit-makers for Eun na Mara, but you could ask Duckflat Woodenboats in Australia.
The new book about Iain Oughtred refers to an alternative cutter rig for Eun na Mara, but I think this is a mistake, as is the index reference to page 152, which should be 155, and the reference to "Avery Brice" on page 93, which should be Brice Avery. The alternative rig that came with my plans is for a sloop, i.e., one head-sail, no bowsprit, so it loses much of its character. I haven't heard of a sloop version being built. A cutter rig would be more interesting. It takes us about four hours to rig and unrig ours (the red one called "Islesburgh"), including the mizzen . She's definitely a cruiser, not a day-sailer. However, once she's set up, I really like her, including the mizzen.

Hi Everybody,
We got back last week from a tour of our friends and relations in the North Island.
This weekend just gone we have taken our boat in a local race from Port Chalmers, which is about halfway up the Otago Harbour here, to Warrington, which is along the coast to the north of Dunedin, a total distance of about 23 nautical miles. We had to go there and rig the boat on Friday, and stay the night in her, to sail on Saturday. We had a fair southerly wind out of the harbour and a good reach along to Warrington, and back to the harbour entrance, which is fairly narrow, but then a strong southerly front came through and we failed to tack against it, so we rolled around quite safely outside the entrance while we took the sails down, then we radioed race control and motored back to Port Chalmers, the last boat back. Our GPS recorded our moving average speed as 3.9 knots. We stayed another night, hosed the boat and trailer and unrigged her, and came home on Sunday. It was good, but it's quite a big effort just to go sailing for one day. Regards to all,
Ian
