Boat Wash Brush

[Dino]

Any recommendations for a good brush for washing the decks and superstructure of fibreglass boats. I always seem to break the cheap car wash brushes. I recently bought a Swobbit Soft Flagged Brush and handle but I’m not sure if it fell of the back of my boat while cruising or whether someone swiped it.
Was thinking of going for another Swobbit brush with maybe a soft and medium head. Or is there anything else out there?
Also, what’s your favourite boat wash?

I know this is not what you wish for but I have one of these and find it very useful on the boat.
