Thanks for the appreciation folks...
Martin, your cosmonauts had me laughing
Here's what I've written on Flickr about it..
This stretch of beach has become heavily silted up, and as you can see, it's covered in sea grass...when the tide is sufficiently high enough it gets covered in water several feet deep, deeper still in the gully's. That lifeboat is in one of them.
I'd say it's someones long-term project that's broken free from its mooring and ended up here. It looks a bit bizarre to be honest. It's like the mystery prize on the old TV quiz show Bullseye where the contestants had to score a hundred 'n' one or more with six darts...which was invariably a speedboat stuffed with bikini clad blondes when the contestants lost, or this when they won
The platform in the distance is a survey platform for the power company, National Grid - there's to be a new high voltage cable coming down from the proposed new nuclear power station located at Moorside, which is up the north-west coast (Lake-district National Park) and it'll be getting tunneled under the sands of Morecambe Bay and into the existing power network at Heysham.
