The plan is to get my mum into sailing. Racings not her thing so the Merlin idea did not go down well. I think she has seen a photo or two of me swimming beside one.

Mums idea of sailing is potting around on a lake or the sea, in light breezes on a sunny day.
We would not be looking to break the bank Of Dad so under £1500 would be ideal, cheaper even better. I don't mind doing some work but not total restoration.
What boats would fit the bill? It needs to be stable, big enough for 3 or 4 adults and easy to sail.
I was thinking wafarer but I'm not sure which versions the best one. I know one type has lots of storage which would be useful. My only concern is the weight of the boat.
Or is there a better option?
Any advice would be well appreciated and gratefully received.
