I have a Zodiac Medline II, it's my 4th Zodiac and the largest/best I've had thus far.
The Med II is a superb bit of kit - admittedly it's not a Humber or other such rugged utilitarian (I mean that in the nicest way Humber owners) RIB, however, it is just as capable given that one does not purposely launch in a GF 9, however, if caught out in one, you'd be as safe as the rest of them.
The difference - dare I say advantage - over many other makes / styles of RIB manufacturers comes when one seeks something suitable for all the family. i.e. Sunbathing - Picnicing - Swimming etc. The Medline comes with optional picnic table and sunbathing cushion set, the Med II has these as standard with an extended sunbathing platform at the stern.
Therefore, you have the best of both worlds, size (6 mtrs), power (150hp max), comfort (lots of bench seating/sunbathing and dining area) as well as a top brand with associated craftmanship / warranties and xudos etc.
Anyway, there are plenty of pictures on here of mine and more than adequate amounts of information on the web. However, if you'd like a trial I would be more than pleased to extend an invitation to you and your family for a day out on mine.
Unfortunately, for the next two week I am travelling around the Middle East and Russia, however, I would be free over the weekend of 12/13 March.
I am based in Abersoch N.W. If you fancy a spin and could be bothered with the haul that far north, feel free to advise.
In the meantime, good luck........
If you buy one of these, you always have beautiful, scantily clad babes aboard.
Buy it & Use it, then sell it and buy something bigger
