Here is a humble bike with a boaty connection.

I bought an old frame on FB Marketplace to be cut up to start a pedal power project for my boat, but when I got it home I realised that my sons old bike had a much more suitable frame, so I cut that up instead. Then I moved wheels, brakes etc. to the old frame and added an old mans saddle, and cowhorns to remind me of my teenage years. It's very comfy and a bit too big for me.
