Aw man it always freaks me out when I agree with Poly!
Do you want to take 6 people to the CIs or have capacity to take 6 people say on local beach hops etc and be able to take less to the CIs?
You'd pick up a decent enough SR5.4 for that money. That should be able to offer you seating for 2 minimum but would be rated to carry far more.
No matter what you will need the right weather window. That is always a problem with group trips. The right weather for Andre to take his big Parker and Whisper to take one of his cabins may not suit you...
Are you looking for an old[er] boat to do up or something modern that you can just push straight in the water? Modern will have to be smaller for the ££ and I think you will be struggling to get something for that money that would go the distance. £8k might if you are lucky and can be patient get you a 4 year old Xpro 420 which have certainly been to the CIs, probably with seats for 2, but rated to carry 7. I certainly wouldnt go to the CIs with 7 on board... But I'd expect a 4 year old boat with no obvious issues to be up to the job with 2 on board in the right conditions.
