Don,
I ended up putting a second set of oar sockets forward. I sit on the cuddy top and row from there. Not the best, but it gets the job done, I guess. I find I want to extend the oars out too far, so need to fight that urge. I need to take shorter, less strenuous strokes. I made oars 10.5 feet long. My crew handled the rudder.
Rowing from the cuddy top worked well enough to get through an adverse tide in the Everglades Challenge a couple years ago, but it is tiring. If anything got in the way, it was my life jacket, as I'd be pulling in and then dropping hands to make the recovery. My hands got caught in the front of the jacket.
I did try rowing from the mizzen seat once, to see what it was like. I left the masts on shore and headed out rowing from the middle seat. I think I felt it was kind of low, as I remember propping myself up on a cushion. My verdict was that it rowed like a 400 pound boat. That is, not that swell. I had left the outboard on, and people kept stopping by, assuming I had engine trouble and was using the oars as Plan B. I guess no one rows in Wisconsin any more.
Lately I've been using a canoe paddle from the side seat near the stern. In calmer water it works great. (Lock the rudder.) I haven't tried it against a full blown headwind. All in all, I have decided the best option is the outboard, even for a short haul. (I aso found the outboard works far better for steering with the rudder blade pulled up out of the water.)
Maybe I should try rowing from a standup position, standing just in front of the mizzen and using the front oar sockets. But the last few trips, I haven't even brought the oars along. They are hard to store.
