If a man buys a boat, he's going to spend a lot of time working on it.
Then, he's going to need a vehicle with enough power to pull it to the water.
When he gets the vehicle, he'll probably ask you to sew an anchor rode bag for some rope.
When you've finished the anchor rode bag, he'll think it a good idea that you know how to drive the boat as well. So you'll take weeks of lessons on Boating Essentials and learn all about charts and plotting and buoys and daybeacons and how to avoid the chunky bits that litter the ocean waters.
He'll want to eat well out on the boat, so he'll give you some boating cook books for Christmas (at your request).
If you give a man a boat.
