I cant believe how flippant some posters on this board get, when one asks a serious question one at least expects the decency of a serious answer. So with that I shall try to oblige.
The idea of airbags to at least try and stop the boat from flipping over is sound but as some who have replied seriously have said the weight and deployment speed could be their undoing. So IMHO what is required is pneumatic floating devices which when not in use sit snugly either side of the boat, these will double up as fenders.
If the boat should exceed the manufacturers recommended lean angle these fenders/floating devices will be extended at great speed out about 5mtrs thus bring the boat back up to within the manufacturers lean specifications.
Very little mechanical devices will be required just a couple of old fairground pneumatic rams, a couple of compressed gas cylinders and the inflatable bits of a RIB. All can be easily installed over a couple of weekends.
The only down side I can see is if accidental deployment of these devices occured whilst in a marina, although I'm sure most would give you a wide berth just in case???
we're at last converging on a realistic and workable solution. The inflatable balloon seems much better, and still offers the no-mooring fees advantage. I would imagine that a larger anchor will be needed: if there's one thing worse than being in a boat heading to the shore in a storm, it's heading towards the shore in a boat which will hit it fifty feet up the cliff.
I would indeed like to borrow your bath for another project of mine, the MattS "perpetual farm": A hutch with a gridded floor is placed over the bath and is home to some rabbits which live on a diet of weeds and grass clippings. Trout swim in the bath underneath, living on a diet on rabbi pooh, and their water freshened by a hose pipe with the overflow open but the plug shut. the rabbits and the trout can be either eaten, or sold, or fed to some nearby mink and the mink then sold for their skins, the carcasses being fed to a dog which i will permit my son to keep provided that he mows the lawn and feeds the cuttings to the rabbits. The experimental stage will allow me to balance the correct numbers of mink, trout and rabbits. Do you have a hutch I can borrow too?
Now - all you lot are so worried about how to right the boat if it gets tipped. Now surely we should be advising the guy how NOT TO GET INTO THE SITUATION in the first place.
Right so causes :--
1) Big Waves -
Solution (a) Stick to rivers (except the severn with the Severn Bore - which is actually a big wave that goes right up the river - big and scarey - people surf on it you know)
Solution (b) Dont go out when it is rough. Use a new technique called "listen to the weather forecast". Along with "ask a fisherman" - both seem to have a really good handle on how big the waves could get.
2) Point at the swell.
(a) Now assume (if you are that stupid) you get caught out in say force 3 or maybe even bigger, have TWO engines then if 1 packs up you still have the other.
(3) If the Boat does get full of water
(a) Buy a Liferaft - put the liferaft in a very safe place but accessible so that you can pull the cord, inflate it and jump in. Hey bingo not only are you say but if attached to the side of your boat may even right it - in which case jump back into the boat and off you go.
(b) Buy an ex RNLI Lifeboat.
Well I,d be interested in the legs Matt. If only for.
Instant. Free, DIY. Marina base.
Or perfect for fishing trips.
Stopping for tea, half way across the chanel.
Antifouling.
You could park anywhere!
Order me a set please. Visa No 435678 879543132
What the bloody hell are you doing out there with seas that can turn the boat over. Why not get a brain installed and leave the RNLI to sit quietly in the pub rather than risking their necks rescuing foolhardy prats with overactive ego's.
I'm shocked to read that you have assumed my postings to be lacking in seriousness. I can assure that having spent at least 35 minutes researching my novel theories, they are in deadly earnest. They laughed at Newton you know.
Your alternative, and possibly competitive solution interests me. I've searched my local fairground looking for inflatable sheep, but to know avail. But I did find a spare rib at the Lotus garden last night. Will this do?
Great plan Arthur - trouble is don't these things have a hole in the middle so the as a boat the mini-rig is not good. I'm still thinking that the ability to walk ashore on 12m legs could be quite amusing. And ever so safety orientated.
