UPDATE: Since this seemed to be a popular subject I thought I'd provide an update. More to come but my dad posted this in the L40 facebook group.
"I just sailed with my son Kurt and his love Rennee on their new L40 from Fort Lauderdale
Pond in Virginia. I am 92 years old and have bad legs from 28 years in military. I had no trouble getting in or out of the aft port bunk. I made sure I knew where my next hand hold would be when I moved about the boat
, remember one hand for the sailor and one hand for the boat
. As a result I have no black and blue marks. Loved every minute. Stood watch with Rennee 2 on and 4 off. Worked well with my bad legs and she a new sail boat person."
Thanks again everyone for all the opinions and advice!
