Beaching legs imput please

I was chatting to Born free and he gave me a link to atom beaching legs and then Bubble emailed me and had been thinking about beaching legs so I thought I might throw it up here for discussion and thought on how to and anything else that some one might brain storm
www.atomvoyages.com/articles/improvement-projects/261-giving-your-boat-some-legs.html
Being an up and coming tony abbott pension I'm looking at cheap ways of doing things over the next 10 to 20 years and Id say are many others as well
Even Mangrove frog is interested also

From memory a little while ago Practical Boat Owner magazine had a article on how to make and install them

If you want me to I can find it and scan and email it to you

yeah hayden if you can forward me a copy that would be great.. thanks donk the more info I have the better..

will do Bubble

I would be too scared to try it with my boat. A lack of tide range in most of Oz must limit the usefulness.

They dont have to take to much weight the keel does that and the best thing is it extends the cruising ground you can get in there with the catamarans

Yep, seen them do it. Also seen photos where they fell over, usually into soft mud. They have 5 or more metre tides more than we do which allows a long time to dry out.
I could picture my boat falling over onto hard sand with broken mast etc. just me, scaredy cat.

I helped a old German guy in Muddy bay seal up his old wooden yacht we just used wooden poles lashed to the sides worked for weeks I was good to see when the tide came in and it didn't get above floor level in the cabin and the yacht floated took a lot of chalking

you could set an anchor on both sides in the articular his boat fell over

Legs are really only suitable for long keel yachts or moulded keel yachts.

Using them on a fin keel yacht I think is inviting disaster. If a fin keeler falls over there is going to be some serious damage. Apart from that, when a fin keeler is standing on it's fin the load on the hull is reversed from when it is floating. You have the weight of the yacht trying to push the keel up through the hull.

This is why you have so many Acroprops under a fin keeler when it is on the hard stand.

Surely the Acroprops only stop the boat from falling to the side and either forwards or backwards, but don't actually carry the weight of the boat. On a long keel boat, as you say they are there to provide side support, whereas with a fin keel you need to provide fore and aft support as well.

I did notice when I had my walker out as I had not used a cradle lift out before being a keel kick I pull the hull in to tight on the cradles side supports and marked the rub rail a little so when I notice this while on the hard I released the pressure between the cradle and the boat she sat there OK so being a long keel she should be reasonable stable with beaching legs




What I need to work out is where should the beach legs be located along the side of the hull the main mast side stay appear to me to be to far forward to support a beaching leg and where the cleat is, where I think it should be
Or even below the forward port light

rear chain plate support

Just too much effort!

What you need is a good mate who has TWIN keels and just lean on him!

Trouble with that NSW I could see a hangover coming

Another idea that I'll try to describe.
A heavy plank of timber or steel on the ground, sit keel on it and fix chains from stay plates down to plank ends.
Use turn buckles to tighten.
After beaching my 12 ton yacht many times I find as long as you keep that mast vertical then there is little weight
On the supports.
Happy sailing.

Dezman in my photo above see my kleat could I possible use that and how wide a plank would be used lets say with a beam of 10 feet 2.5 to 3 meter beam.
With the atom props you can dismantle then into half size and maybe store them in a forward cabin for a plank Id have to make it similar some how

Storage is a problem for one off use, my friend used a plank of 8+2 for his small yacht and had one side always connected
And the other end he would walk around and fix onto plate. Having worked out length and a weight on the board to sink it.
Now with a heavier boat it needs to be strong enough not to break in two with the keel on it, you could laminate extra in the middle.
Maybe someone could workout what's needed on your yacht by saying if you stuffed up and had say a 15 degree lean on it how much
Pull would there be on the board!
I know the middle has to be strong as the sand can give way a little under the board, but gee try and break a railway sleeper.
You can place it along the gunwale ready to use every time you see a nice beach in Queensland North of Fraser Island with bigger
Tides.
Iv tied halyards of the mast to mangroves to hold up my big girl and its easy once you've done it, never liked paying that Hugh bill
On the slipway for a quick anti fowl.

Really interesting topic. I keeled over once, see profile pic. Since then, a few times I've found myself on a mud bank, I am jumping from portside to starboard and back that's actually driving the keel into the mud until stable. I'm shallow draft with 3.5 m beam.
Methinks, a few set anchors tied firm to stanchions,,, until possibly shoveling sand against hull, inflating a tractor tyre or two also sounds good. This way ive got more reasons to keep spare anchors, extra rope and some awesome skiing equipment... >.>

Magrove maybe I should fit these babies might be able to bare foot then lets get the boat of yours planning mate

Many thanks Donk am looking forward to this read so was Bubble

I also notice inside your forward cabin is a little different to Don I have ribs showing you your do not

Took this photo first day after I bought her you can see I have ribs along the hull side I did see a photo of yours a while ago when you were looking at her and noticed a difference there as well

Your is in better shape than mine is Ill bring her back

I think my main mast is around 11 to 12 meters Id be interested to know height your mast is don as a sloop against a Ketch
