Is there any consensus on righting line rigging for the Blade?
Where attached, stored, deployed? How long a line?
At this time, I just have a 3/8" line stuffed in the forward tramp pocket. That will probably take to long to deploy.
Thanks

I've got a 10mm line, about 5m long, I think. I store it in the tramp pocket, and on the first capsize of the day tie it round the dolphin striker and then chuck it over the top hull.

I used to leave it tied round the dolphin striker, but the bowlines kept undoing themselves as they got pounded by the waves. I lost one rope this way.

I'm sure you could go thinner for weight reasons, but I'm not a big fan of putting fine lines over the hulls and then putting all my weight on them.

I use an 8mm line, about 4m long, tied AND TAPED around the dolphin striker. The key thing is, it's kept in a pocket that closes with velcro, and it's on the UNDERSIDE of my trampoline just behind the main beam. It's protected from wave bashing by the mainbeam itself and is instantly and easily accessible once the boat's gone over.

It also doesn't take long to stuff the line back in once the boat's 'pointy stick up'.

You can also attach a couple of padeyes to the front crossbeam one each side for a 8mm line (non-abrasive) with a bead on each end and a small block at the rear center of the tramp for a bungee to hold the line in place. I’ve seen several Taipans set-up this way and for the lighter platforms its working well and saves time. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

That is actually a very neat trick. We must add this one to the open-source F16 design.

Any pictures of that setup? I am interested to see how it looks.

JJD,
If you are new to the boat and expect to be using the line a little its good to have one that is quick to use.

I use 8mm silver rope. A real cheap synthetic rope that to me seems a bit like flax. It does not seem to absorb water. I tie a knot in it every 12 or 18 inches.
Attached it to either each side of the front beam by popping on saddles undeneath. So the line goes from one side to near the centre of the back beam and then to the other side in the shape of a "V".
This line is kept tight by a 6mm shock chord that goes from the middle of the righting line to a pulley in the middle of the rear beam and forward to the striker post.

This will get you up the quickest because the line is continuous you can grab the lower section and pull in the slack and use it to pull yourself up onto the hull.

So when righting the boat you put the line under your trap hook to take the load.The knots stop the line from slipping when they hit your trap hook.
Lower arm holds up some tension and upper arm pulls in slack to move up to the next knot as the boat starts to come up keeping you at the optimum angle and not lying in the water.
If you need more weight outwards you can put the uper arm out past your head and bounce a little to get the thing moving.
Another way is same type of rope with knots but two of them. Going from front to rear beam with two pulleys and shock cords going forward to the saddle the rope is attached to each side. You have pretty good rear beam clearance on the Blade so you don't drag the "V" line in the water at all but some people just rather two lines.

Anyway there is often more than one good sollution to any given problem and over the years these have worked well for me, on a number of different boats, including the Blade.

Hope this helps.

Regards,
Phill

OK here is what it looks like.. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

Red line is bungee - white/blue line is the righting line.

Thanks for the quick responses guys.
I appreciate all the help and advice I get.
Saw a similar setup to these on a local A cat but wasn't sure it would adapt to a Blade.
I'll try it.with Phill's knots.

John,

I have the same system as Buccaneer. I works great but would be a pain with the periodic knots Phill uses because they will catch on the bungeed ring.

Eric,
In my system there is no bungee ring with the knots.
Not needed as the bungee is not supposed to slide along the line. It is a bungee and stretches. In the beginning I had it without knots but found it much better with them.

Regards,
Phill

I have a slight vairation to this setup.
The bungee and the A section of rope is the same but my rope doesn't end at the front beam with a bead, it continues to the rear beam on both sides hugging the hull before its TIED OFF. You can then grab the line anywhere between the front and rear beam on the raised hull to manover your wieght to the best angles required and for 2 up there is room for both to grab the line.

Good point maybe good for doubles but this will also move your balance point considerably more towards the aft. For solo righting with the Taipan system wrap the line with bead around your trap hook twice sit back and she'll normally come over first try. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

Does pulling from the upper beam rather than throwing the line over the hull produce less righting force?

No, but it will increase the amount of tension on the rope needed to lower your body to any given angle. So, if you use knots and your trapeze hook, it's probably not a big issue. If you're trying to hold the rope by hand, you may find that you can't get your body as low.

What sort of crew weight per platform weight ratio is needed to get the boat on its feet from either a complete turtle or floating on its side?

I generally go with getting on trap while on the beach : if the hull lifts, it will come up if turtled. But there was a post detailing a method where all the weight is shifted to one corner, sinking it and allowing the opposing end to come up.

I've never had any trouble getting the Blade back up on my own, and I'm about 85kg. I've only ever capsized the Blade in a fairly decent wind, and I think I'd have trouble in very light wind.

I've not turtled the Blade, but I've had done with other boats. The only technique I know for righting (without a powerboat) is to sit on very back of the leeward hull, so that the bow of the windward hull lifts. The boat will (eventually) end up on its side.

Paul you and me are the same weight. If there is no wind, do not plan on bringing your blade up singlehanded. Been there done that too many times.
