All the liveaboards I know or know off do a great job of keeping their boats and surroundings in good order, apart from a well known one in the stalham/sutton area who treats it like a dump, don't think I need to say any more!
A great pub about 30 mins walk across the fields from Stalham is Lessingham star, great food and great beer, all social distancing in place, can not recommended highly enough.
I'm not talking of legalities, I have seen the water below the freeboard of that vessel on more than 1 occasion, and when it is it would make refloating much easier.
So is the water always this high then, check this page https://flood-warning-information.service.gov.uk/station/6216?direction=u
You will see it rises and falls.
I never said I had the funds or kit to do it, why the hostile response, just saying how it could be done, have seen it with low tides with the freeboard above the water, it's not an impossible job.
Or on a low tide 2 or 3 high power fire pumps, board over any obvious holes, would soon rise, seen broads boats deeper than that raised using that method. Drag to Richardson's or sutton and crane out.
They couldn't build the 42 fast enough a few years ago, for the size probably the best sea going boat out there, the RNLI had 2 of them for training which says something. What changed?
Oyster and windboats parted company about 7 years ago, that's when they took over hardy's after Mark Funnels death. Len does own the land in wroxham now after windboats moved to the more practical site in North Walsham in 2018!
Yes, they bought Hardys after the unfortunate death of Mark Funnell, still launch all their boats at foxes in Ipswich, have a full order book at the moment!
