hello there.......i would wait til something else pops up on boats and outboards, because none of the ones you have selected are excellent boats, however some would do sufficient, for the occasional venture offshore, like the avon 620, which although not a true offshore rib, will handle its own in moderate stuff, i would suggest holding on, and you will find a large selection for your budget!!!!! personnally i can recommend a humber, we have a 6.3m ocean pro, and cant fault it. the bombard you list, looks OK, but i reckon you could do allot better, selva, wouldnt bother with it, how about.....
as a good smaller boat
slightly underpowered, and doesnt say what seating, but looks good on surface!
This zodiac isnt the ultimate 4x4 of the sea, but its a good boat, and is a good all rounder, not a great offshore boat, but if its just the occassional venture, may do!?!?!
Good small boat
others currently for sale on there would go a bit beyond your .....extended budget haha, which believe me, even when you buy the boat will end up gathering extra costs too, haha
p.s. for that money you can almost get a new humber of 6m size with decent suzuki!
