Largest is a Sealine S24 then 6 Fletchers 2 Ribs 2 net skis and several sibs most have 2 strokes the largest outboard being 200hp the smallest being 2.5
I manage to look after them all ok
If you think that is a lot I have over 220 RC planes and 10 plus drones
Each to their own
We have a bloke at work who is into his rc planes big time, I have no idea how many he owns.
Not sure if it still the case, but smalllish boats have been selling really well as people cannot go on hols.
