Looks like exactly what you want for rivers and confined waters, where you want more sail area up high to catch wi d that isn't blocked by surrounding topography/obstacles. Also gives excellent visibility down low: another plus for sailing in tight spaces. And the fact that it doubles as an awning? *Chef's 😘
whoa, this small piece of rope at the end, instead of an attachment to the boat as in chinese Yulohs, nice, I need to try that, and much better than getting the twist just out or your wrist.
Technically the yuloh is more efficient, since thrust is generated during both motions of the stroke, where an oar is only thrusting during half of its movement. The oar's relative inefficiency is compensated by other factors such as using two of them simultaneously. Other advantages of the Yuloh are that you can face forward to see where you are going, and your profile is slim in narrow or congested waterways.
Is the yuloh the same as the one in the Wooden boat magazine article a few years back? What's the music by the way. I'd like to listen to it while I plane wood.
Hi Tom, the spreader is connected to the mast using 3/8" polyester line. The mast cap is made of 2" hardwood ball, and a half of lacrosse ball (rubber) is under spreader. The rubber ball has some wear and tear after the season, would probably replace it with hardwood ball next year. Similar "universal joint" was also tested on a smaller sail (kayak in other video) and it works reasonably well for sunfish sail as well. I've just uploaded some photos, link in description. Happy sailing!
Great video. I have a Sunfish sail that I want to rig just as you have done. I cannot though make out the detail of connection of the mast to the yard. I have seen the simple rope method shown in the 16' Trilobyte plans, but I have been told of using a rubber ball as part of the connection. I just cannot see it in small detail in imagination. Could you please post a picture? Your video would be of interest, I think, it sent to Duckworksmagazine. com Thanks. TomAndrews36@gmai.com
