in my opinion these are the makes to consider
when you want to do offshore runs + waterskiing with a 5.5 meter boat.. 75 HP would be the minimum .. better go for a 90 or something..
Ok then, i have a few problems with that...
Yes Humber, Tornado and ribcraft are well built boats but they are VERY heavy, which is not what hixxxy says he wants.
If you want to take 5 people across the channel then they really all have to be seated and finding a humber with seating for more than 2 is quite a rareity.
I would not buy:
Zodiac (unless military)
Valliant Vanquard (DR and Patrol are OK though)
Explain yourself.....if any boat is suited to waterskiing wake boarding and the odd cross channel run then it could be either one of the boats you have listed as a no.
Now then, Zodiac open pro 5m or 5.5m - Great boats, well built, deep v hull, and they are quite common on the second hand market, infact there is a 5.5m with suzuki 115 4/s on sale at the moment.
Bombard - very very similar to zodiacs.
Valiant - I had a valiant vanguard 490 and loved it, it had a yamaha 60hp 2/s and did about 40mph, it was perfect for water sports and i would have nothing against taking it to france in just about nay weather. Its ws used on the solent a lot on the rougher days and was a joy to drive, landings were soft and it handeld like a dream. (wishing he haden't sold it)
Back to your original comment, the Vanguard and the DR are the SAME boat. Maybe different tubes but the same hull.
Valiant patrols are very expensive and ive never seen one smaller than 7m second hand.
Id have a look for pretty much all the boats mervyn said not too.
No offence meant to mervyn at all, but if a guy is after a family boat for water sports and having fun then a Ribcraft, Humber, Tornado is not best suited.
