Less expensive than the boats, but as beautiful, are the hand-made wooden propellers that David, now 84, still crafts in his workshop. They were born out of a need to find exactly the right gearing for his pedal boats.
“If I wanted to experiment with cadence rather than change gears, which I didn’t know how to do, I’d just make another propeller with a different pitch and that would do the job for me,” he says. He makes them painstakingly, joining pieces of wood to create a rough shape and then using his craftsman’s eye to sculpt the propeller by hand using simple tools and sandpaper.
You can buy propellers from dadsboats.com and prices start at £149.
