Just bought from Marinescene who have lowest prices for Marjoni fenders. Size 1 would be OK for general use but if you moor alongside regularly size 2 might be better. Total of 6 is enough. Good sorce of reel ends of rope as well.
A beatiful large fender in a lovely deep blue velvet cover drifted past our boat in the marina a few weeks ago. My Son grabbed it as I thought great, I can use that. Then SWMBO said that there was a large Italian mobo at the other end of the pontoon and their fenders looked similar. Next time I walked past I had a look and could see four identical fenders with covers on one side and three on the other. He even had lovely deep blue matching mooring lines.
There was no-one on board that time but next time we walked past I handed it to him. He was very pleased as he clearly thought it had gone forever. Ciao!
All fenders look bigger when you buy them than they do on your boat. Corollary: buy fenders which look a bit too bit and they'll be just a bit too small. Note: it's almost impossible to have a fender which is too big for use, if not for storage.
I got a couple of the 9" chubby ones cheap at Ardfern this summer - from a cancelled order - and they are excellent. I never attach anything to the eyes at the bottom of my other fenders, so that end is just wasted storage space.
It's particularly useful to have a couple of fenders bigger in diameter than the others when one has a boat which is pointy at both ends.
