Hoist Safety….!!

Hi again

Sorry to totally bore you with rules and regs but this one is worth considering, if you lift a boat on slings then you should either attach the slings to a set of brothers (long chains which mean that the angle created by the slings is 90 degs or less as loads increase inwardly onto the hull exponentially the further you go above 90 degs.) or you fit a set of spreader beams just above deck level to take the compression load. If this is greater than 90 degs you risk damaging your boat due to compression loading.

Again I must say I would not work under a slung load whether it is suspended by hydraulics or by mechanical lifting device such as a chain block or pull lift as the slings can easily slip espescially forward due to the hull shape.

Believe it or not lifting is the biggest killer in the north sea and should not be fooled around with if you are unsure then you should seek professional advice.

Hopefully not bored everyone to tears


FF Crane at Freshwater Bay – The Plan…!!

Starting to wonder which UK Clubs could gather up the resources to try building a Freshwater Bay type crane?? No more wading in up to your armpits at Hayling!!??  Richard Blaquiere kindly also made a quick drawing that we can see.  You’ll find an example of the £200 electric motor in the blog a few days ago.

FF Cranes at Freshwater Bay…..!!

So now you’ve had the news about the Cricket, then I forced you to look at the amazing cranes at South of Perth YC. There’ll be a few brits choking on their porridge now…..

So is there a kind of “next level down” approach with lighter, cheaper cranes tuned to the needs of the FF??  Richard Blaquiere has kindly also sent us some photos from Royal Freshwater Bay YC in Perth.  Take a look at this !!  This is still motorised – see the motor mounted on the boom…

Now that’s a bit more… well, British, don’t you think !!??!!

Here’s a few detail shots

FF Cranes at South of Perth YC…..!!

Since the blog chatter started off by Helen Hepworth in Hong Kong pointing out that the Aussies all launch FFs by crane, we had additional contributions on cranes from Andy Murphy and Richard Taylor (South Cerney).

Now we suddenly have a flurry of FF crane photos and diagrams to show you!!

The first is from the home of the largest FF fleet in the world (any comment from HISC members??!!) at South Perth, WA.  It’s a pretty stunning and well capitalised setup there, but if there are any UK Commodores reading this you had better sit down….

This is pretty industrial scale craning, and reminds me of the setup at Medway YC.  You can see though that some of the cranes have both large and small cranes built in.

Uk readers should try to ignore all that blue water, cloudless sky etc.

Now you might be thinking, “That’ll take a while – how you cope trying to launch a whole fleet quickly?”

Answer – lots of cranes!!

Thanks to Richard Blaquiere for the fabulous photos!

Craning a Launching Alternative for Some Clubs….??

Corby craneWe had some chatter on the Blog recently about the attraction that cranes might have over slipways at some Clubs.  Indeed, to my surprise, we did find a few UK Clubs who crane already.

For Dragon craning, we had pretty big bits of crane which cost serious money – and would be too much for many FF Clubs to consider.  And so I was delighted when Richard Blaquiere wrote in from Perth W.A. ….

I’ll try and get a picture of the FF crane at Freshwater Bay. I’ll also get some basic measurements. Height of the boom of the ground, and its length. I did a design of a small ff15 crane for our club, before they built the new facilty.  It was very simple, similar to the small cranes they use to lift dingys off large boats. Remember a heavy 15 is 350 kgs. on weight 15 is about 315 kgs. Have a look on EBay for a small material lift, that has SWL (safe working load) of about 750 – 1000 kgs. The material lifts need 240v single phase power. ie stand power point. They all usually have a hand held pendant that controls the up / down of the hook. They are very cheap in Aust. I would think they also quiete cheap in the UK. The design I had done used one of these material lifts.  The gantry was made from 150 x 50 x 3 RHS, and the base swivelled on a Wheel hub and a stub axel. All hot dip gal after fabrication. 

I’ll see if i can find the sketch that i did.

cheers, Richard Blaquiere

Richard also pointed me at the type of motor that an FF crane would need.  I was amazed to see that we’re only talking a couple of hundred pounds. This is what they look like… not large at all.

Launching Fifteens by Crane……!!

Did you notice that the poster for the Broxbourne Open says they have launching by crane??  I think that Torbay used to crane as well. As does Dinard I think.

I used to be fine about craning my Dragon – it’s dry and convenient once you have it set up.  Andy Murphy had his FF built with craning points  – basically two eyes screwed on to the keel bolts most over the centre of gravity.  That’s where your sling attaches.  When the boat is up in the crane, the next issue is how to steer it in the air, or at least control its spinning. You do this with a pair of lines – one at the bow and one attached to the stern. You can obviously use the painter in its normal position at the bow, but ideally you have little loops at the gunwhale near the stern to attach a rear control line. Then you’re done!!

On my 2012 boat I decided like Andy to have it fitted from new. You never know when a trip to Dinard might arise!! Or Broxbourne !!!

Flying Fifteens in France….

The FF members in France have their own website… in French. Dinard is the central fleet and their French Open Championship comes up later in May. (Andy Murphy wants to go…)

To launch, they crane their FF’s at Dinard. If you browse the website, Andy, you can get some idea of how their craning routine works…. (nice photos on the website…)
