Replacement tillers
I don't know what the original looked like, but I replaced a non-original tiller on my Oday 23 with a laminated curved tiller I got at West Marine. The non-original tiller I inherited from the previous owner was a very nice straight stick of oak (rounded sides, etc.), beautifully finished. However, it was uncomfortable to have to reach down to steer, and when put hard over, it would invariably bump the knees of the person across from me in the cockpit. This new tiller has a broad, upward curve and is MUCH more comfortable to use. It also looks really cool. I highly recommend a curved tiller. The one I bought is made by H&L who made the original tillers for a lot of popular boats. Both West Marine and BoatUS (and I think Defender too) carry them. I bought model 112F, which is listed as the direct replacement for a lot of boats from 25 to 29 feet long. This tiller turned out to be the exact same length as my "original" non-original tiller. If you are a skilled woodworker, I would strongly suggest you make your replacement a curved model.
