Re: Oars for 12' Alumacraft
Good point, Bob. His 12' Alumicraft would call for 8' oars or even 8' 6", according to that chart. However, unless he's going to be rowing a lot, those are going to be a bit unwieldy to stow in that tinny.
For use as emergency propulsion, I find the 6' oars work just fine on my 12' aluminum boat. They're not as efficient, of course, but I often row troll with them, and can pull for the dock when my engine quits OK, if needed. I rowed it almost 2 miles one time back to the dock.
Still, as you say, if he's going to use oars as the main propulsion, then it's another story. I hope his alumicraft is one of those with a rounded bottom. They're better rowboats than the flatter tinnies.
