Hi Harry, Welcome to the group. You raise some interesting points for an off season discussion. I have been pondering a post I read here (I think) recently about the difficulty of using a single oar as an Oriental yuloh. I believe the geometry is wrong for efficient use of oars with our small boats. Our boats have a narrow beam, short cockpit and high freeboard. If you place an oarlock on the top of the coaming or transom, you have poor leverage for seated rowing or use of a yuloh (yulohing?). Some people stand up, which increases the angle of the blade in the water, and improves the leverage situation by allowing use of a shorter oar. I would be comfortable standing in calm water, but not in extreme conditions. So…if I HAD to use an oar I would think about installing oar ports. The ports would be located about waist high along the sides if I wanted to row or in the transom for a yuloh. Bolger has used oar ports as did the Dovekie. In extreme weather the ports could also function as cockpit scuppers or be closed off if necessary. Ports would also have the advantage of allowing the use of shorter oars. Or..I would consider using some sort of an arm that would locate the oar lock several feet outboard. The leverage situation would be improved, although longer oars would be needed. Modern racing shells often have oar locks mounted outboard. And..I would give a lot of thought to a sliding seat with a pivoting brace for the feet. steve Steve R. M-15 #119 Lexington, KY ************************************************ Greetings from N. shore of L. Superior: -15F,snow& wind last couple of nights but at least my M15 is safely tucked away in its dome shelter! Bob Eeg's tale of the specially equipped M17 that he constructed for the Austrian man was fascinating and raised a couple of questions about the M15: (1) Has anyone tried rowing one, and if so how was it? and (2) What were the worst conditions a M15 has survived intact (wind, waves) with all sails down and only motor power? Pardon me if these questions have been asked before- I joined just last year. If they have please point me in the right direction and I'll check it out. Thanks and safe sailing to the lucky souls in the south. Harry Elmslie
