My honest opinion is go and look at more boats and get a better gauge of what you want. Take the dogs with you
The boats you have posted are
57ft upto 70 ft.
2 berth upto 7 berth
Cruiser, Trads and Semi Trads
Some quite different boats here, and I do feel you need to establish whats important to you
For me the Barry Hawkins is the best hands down, but if you don't need 7 berths, not being able to cruise the Pennines, increased costs, and not much space at the back for your dogs are an issue....then it rules this boat out.
Miss Mollie, isn't a patch on the BH boat, but it's smaller and may be more suited to you.
I'm looking for a boat too, and I have looked at all the 57-60ft boats you have posted....but none of them fit my personal requirements.
