Are you talking about state retirement benefit or additional paymanys like housing benafit, winter fuel payments and the enhancements to meet garenteed min pension provision. As far as I am aware the only possible problem withe state retirement pension ifor ex-pats is that under some circumstances the can be frozen at the level at wich they where paid when you left UK but presumably not if you then reside in an RU state. The additional benifits may well have time limits for travel. For advide I would initialy aproach either citizens advice or help the aged, either should be able to advise you on the best way to maximise pension income whill also maximising sailing time.
