I am convinced that some boaties like working on their boats almost more than being out on the water.
My brother has taken more time building his canoe than he will be using it and he just loves his old Stuart Turner engine for his 23 foot yacht, even though it is most unreliable piece of equipment he has (apart from his Seagull outboard) - but the joy of fixing it is clear.
Just listen to an old Stuart Turner R3M go https://www.youtube.com/watch?v=2Sqmks0W87I and you will see his point.
For PicoMicroYacht getting the job done and being out rowing as quickly as possible is the priority.
But it is a bank holiday and a tyre of PicoMicroYacht's trailer need replacing and the replacement turns out to be the wrong size. And the WaterRower I use to train on is in bits because the tank has just sprung a leak and the temporary repair didn't fix it.
Even though the WaterRower is the best bit of kit I have bought, it has a flaw - the drum that contains the paddle that provides the resistance to the rowing action is joined together by a central seam that is prone to leaking.
