Would recommend the King's Head in Yarmouth Peter J. But other pubs are good too.
(If you want to blow the budget The George is historic and the view is verrry expensive

)
A trip upriver in Yarmouth is well worth it. The berthing masters/ mistresses

in Yarmouth are a mine of useful information as regards tidal tips and places to go.
Worth going to Yarmouth in calmer conditions and Cowes if a bit choppier as you're coming from Southampton.
Have to say we've never regretted a trip to Yarmouth yet!
If we're planning on going that way Sunday, we'll send a pm,
