The standard 6 hour day charter is £540 for 8 people.
If you want to stay on Zen Dog the night after your charter, that's just £50 extra - £590. There are only 4 beds but the sofa can convert to a lumpy double for a further 2 guests.
You can start your 6 hour trip from 11.30 onwards. I recommend stopping off somewhere ashore for something to eat -6 hours onboard is quite a long time particularly if the weather isn't suitable for swimming etc.
Most people book a lunch somewhere (The George in Yarmouth and The Hut Colwell Bay are favourites). We then meet on Zen Dog an hour before your booking and, assuming 2 hours for lunch, you'll have 2 hours for seeing the sights and anchoring somewhere lovely - ideally with the option of a swim or go on our Paddle Board. I'll then bring you safely back to Lymington.
So, here's a typical itinerary:
1pm Meet on Zen Dog
230pm Arrive at Yarmouth Harbour OR The Hut for lunch
430pm sightseeing cruise
530pm anchor for a swim
7pm arrive back in Lymington
