I've got a similar sized boat and it could reasonably fit 4 adults - but it will be quite cosy. Its certainly ok for the occassional trip across the solent in nice weather, and would make it round the island in reasonable conditions.

I suppose thats quite a good way of make or breaking them! If their are "adventurous" and dry suited up then they might love that. Otherwise they'll hate it and ensure you get the boat to yourself from then on! I'd suggest if the OP is looking at a 3000 budget and using it with the family in anything other than ideal conditions he needs to spend about 1/3rd of his budget on drysuits, possibly geckos, good gloves, etc - to keep the family happy.
Personally i'd rather my family were sitting on seats inside a solent 6.5 (even if at displacement speed for some bizzare reason) than bouncing over waves perched on top of the tubes of a 4m boat.
I don't think mollers was criticising the SR4, having towed his dead Vipermax home with one - just questioning whether it was enjoyable 4up in poor conditions - I think you'd definitely want to take a look and preferably a trip in one with the family and canvas their honest opinions. As one person's adventure is another's near death experience!
For the budget involved you are probably looking at something small or something old and tired.
