Should see my bro-in-law; he would live full time on water if he could.
They left for the Scillies ten days ago for a long weekend in an ex-coastguard cutter they have bought, one cabin and shower, a reasonable galley and eats area, a huge open deck towards the stern.
They are still there.....friends who went with them in their boat came back to the mainland and have gone out to join them again.....what they are doing re clothing and stocks, who knows, but I suspect the little (and very expensive) supermarket on Tresco has been emptied by them.
