The Pro 420 or Pro 7-man are basically the same boat. It's lightweight, Strongan Duotex tubes (Thermo-bonded PVC). Uses slide on rail system that the tube collar can fit onto. Attaches at bow and stern with webbing straps. I never removed the tubes, but if you deflate them, then you can clean along the rail system to get rid of sand and other marine debris. To remove, undo the straps and haul back towards the bow. To refit, lube the rail system with Fairy Liquid (other washing up detergents are available
), align on the rail and feed towards the stern.
I have fond memories of mine. Perfectly suited for 40hp 2-stroke engine, but is rated for 50hp if you can find one.
It's got a shallow V hull so will tend to slap in the rough stuff, but we were out in the North Sea and Atlantic coastal and never felt compromised. I even managed to squeeze a Tohatsu 3.5hp auxilliary on, hence the reason a 2-stroke engine is perfect match as it has a fairly narrow cowl.
Zodiac have a pretty extensive dealer network, so plenty accessories, including bench seats, bow seat cushions, consoles, etc. We had 25 litre fuel tank under console, and another under the rear bench seat.
