If there is, I inherited it from my father, who like to spend time in small boats on Wisconsin lakes fishing for muskies.
Maybe there is. I took every chance to be on a boat growing up. (Well, except one, which I still regret to this day: in high school, I had the opportunity to crew on a sloop in the Mackinac Island race; I declined due to homework. Stupid.) You might think college would have been a distraction... but then there was the Purdue Sailing Club.
Our kids grew up on sailboats - Cal 21, Catalina 22, and finally the O'Day 25. The movement of the boat became second nature to them while they were babies.
So... Is there a marine gene?
Erica (Trace Metals Chemist, King County Environmental) and son-in-law Ken (Analytical Chemist, Amgen) have a 17' Larson runabout named Firecracker which seems to get wet nearly every weekend during the Seattle summer. It spends most days in Lake Union or Lake Washington, but sees salt water occasionally as well. They also have a canoe hanging in their carport.
Adam (Lead Design Engineer, PACCAR/Kenworth) went in a slightly different direction. He *built* his boat, a kayak - stitch and glue construction - from Chesapeake Light Craft. It is gorgeous. Green Lake and Lake Union are his favorite haunts. And he introduced Jane to kayaking for Mothers' Day this year.
What do you think? Is there a marine gene? If there is, it must mutate when passing from one generation to the next, since no one has a sailboat... yet. A father can always hope.
(I do know that there is a beer brewing gene - it is on the Y chromosome.)
