Hi Joe,
I'm dealing with age (61+) and Post Polio Syndrome which has robbed me of leg strength to the point where I walk with a cane at all times (sometimes two canes if a bad day). Once I'm in the boat, I'm good to go - upper body strength is still there.
So
Handling boats and getting them to the water:
The GII requires a cart and / or help.
The Kodiak I can just barely handle alone. Help is nice.
Citibot is a piece of cake.
With all three, entering from a shore launch is easy - straddle the boat, sit, let feet drip for a bit and pull legs inside.
But
From a dock it's a different story. I've entered my GII from a dock in a controlled fall several times.
When I do it right it actually looks almost graceful. I sit on the dock, drop my feet into the boat, then lean forward until I can get a hand on either coaming (washboard), swivel my butt off the dock and lower myself into the boat. This requires arm strength adequate to support my whole weight. Getting out is "simply" the reverse but is much harder as I'm lifting my weight up onto the dock. If I'm really tired, I throw grace to the winds. I flop my upper body onto the dock and roll over, pulling my legs out of the boat. It entertains the onlookers.
In all these maneuvers, be sure the boat is tied up to the dock securely or you will push it away from the dock and either fall in the water on entry or lose the boat to the winds on exit. Both are embarrassing.
If you don't have the arm strength then I'm thinking docks are not for you. Anybody else have a method for entry/exit using something other than arm strength?
Actually, for me, getting OUT of the boat on shore (no dock) is the hardest for me. In my GII and Kodiak, I place both hands on the washboards and lift my body until I can get my legs under me and kneel in the bottom of the boat. From there I take the two halves of my Folbot paddle like they were canes and jam them into the sand on either side of the boat. Using them for support, I can get my feet under me and stand up. Then I just step out of the boat.
With the Citibot, I put my feet over the sides and, using the two paddle halves, stand up on the sand, straddling the boat. It's a little easier depending on what the shore is like.
None of these exits is graceful, nor are they easy. I'm sure I'll have to develop better ways as 70 creeps up on me.
