Date Posted: 15 Oct 05 at 4:32pm
Just been out sailing in my 14 again after it being out of action for 3 months. Great fun but I'm still having major issues righting her after a capsize. I sail with my sister and our combined weight is around 21.5 stone so righting it is never going to be easy. The boat always lies with the hull upwind of the rig across the wind, when we try and right it the boat does not turn up into the wind at all making the fully batterned main power up a bit. Ditching the kicker doesn't help either.
We tried swimming the bow into the wind but when we then tried to right it it started to bear away again. I'm going to try righting the the rig upwind of the hull and having my sister hand onto the trapeze handle next! Nothing else seems to work. I've never had any issues with righting RS800's or 29er's.
Any advice guys?

Jib sheet eased? If the boat has a self tacker, it may be that there isn't enought throw to the cascade and so the jib is pulling the bow down. Add length somehow.
Anoher possibility is that the tiller is not staying on center. SOmetimes the heavy double tiller extensions are enough move the tiller and rudder around, can cause the boat to beart away or tack on top of you as you are comming up. A good bungee to keep the helm centered often helps keep things normal while you fracas.

Some other suggestions:
Try hanging onto the centreboard as the boat rights and go under water with it for a few seconds, this should stabalise the righting. You could also try scoping your crew in as the boat rights so you have some weight that can balance the boat. The crew hanging onto the bow might also work combined with going under with the CB. Tie some floatation to the masthead and practice until you find something that works.

If its really windy
This was written by well known Australian designer and sailor Frank Bethwaite, it applies to all two handed dinghies, not just the Tasar he mentions. I have permission to reproduce it on http:.//www.islandbarn.org.uk/training/try-index.html - my club website so here should be OK.
About 1983 the Australian Navy purchased the first eighty of what are now about 160 Tasars, and I worked with their coaches to develop safety drills specifically for the Tasar. This took the form of sailing in extreme conditions (25 to 30 knots) and deliberately capsizing and recovering to prove what worked, and to learn what didn't work, when the chips were down.
We learned that in strong winds even a strong young man cannot swim an Inverted Tasar head to wind. The windage force is too great, and all the crew does is to exhaust himself or herself. So lesson one is to accept that the boat will lie crosswind, and don't try to do anything about it.
Lesson two was that in winds exceeding about 20 knots even two strong men could not right a Tasar "to windward" ie. with the mast downwind. The windage on the inverted hull and the two crew drove the boat downwind at about ¼ to ½ a knot, and the force of this flow of water onto the sails was simply too great for the crew to oppose. Conversely, the slightest righting effort the other way, ie. with the mast breaking out to windward, rolled the boat upright very quickly.
Obviously, any boat righted with the mast to windward in strong winds will flip straight over the other way as soon as the wind gets under the sails unless you do something about it. What to do about it is that in extreme conditions one crew mounts the hull and, when ready, pulls the centreboard to leeward. The other goes first to the bow; then as the mast approaches horizontal moves aft under the jib and grasps the shrouds, and hangs on. As the boat rights this crew member is lifted out of the water outside the hull, and this weight prevents the boat from capsizing again.
This crew member then acts as a sea anchor and the boat is stable even in extreme conditions for as long as he/she hangs on. This gives time for the other crew member to board. He/she can ride the centreboard under the hull and emerge to windward, or board over the low gunwale from leeward, or swim around to windward and get in from there. The trap here is that when you are on the leeward side in extreme conditions the drift speed of the boat drags your legs and lower body under the boat. Even young sailors proud of their strength could not get in from the lee side in winds stronger than about 20 kts, so in the interests of avoiding exhaustion we recommended swimming around the transom and mounting from the windward side. The person in the boat cleans up as necessary. When ready, the boat can be rolled to windward to lower the windward gunwale for easy boarding of the second crew member.
My final tip comes from Air Force training with inflatable dinghies. The easiest way to board any raft is to kick your legs horizontal, lunge, and go in head down like a fish. If you try to get in with your spine vertical all that happens is that your legs go under the raft, and you become exhausted.

What about sinking the bow to get the boat head to wind, think that's part of capsize recovery on cats?

what about one of u holding the bow as it is righted so that it turns head to wind?

Hey first of all do you have an aluminium mast? if you do then you will
find it very hard work, the older 14s with aly masts are a sod to right!
The technique you mention has been adopted by alot of us because the
carbon mast boats will sit with the sails to windward - free all
sheets, then one gets on the board and the other sits in the crewing
position holding the (going to be) windward wire and the mainsheet - as
the boat comes up u sheet on ever so slighty trapezing into the boat
while the person on the centreboard hops in keeping their head low -
that way you can both end up in the boat it looks cool and one of you
can grab the helm!

The mast is carbon luckily. I'll give the mast to windward righting method a go and see what happens.
The boat came with pretty thick elastic around the tiller but I'll replace it since it's in a bad state. I've put twin tillers on (2 rs600 extensions) which are failry heavy so this might also be an issue.
A few other thinks to try here too, cheers guys.

I own a laser 5000 and my helm is fairly light what we do is start righting the boat and as it comes up he hops in and i grab the trapeeze loop and use that to bring the boat up (it also helps you get back in too!) This seems to work for us .

To depower a fully battened main I would pull the Kicker and Cunningham max on.

You think kicker on would make capsize recovery easier? My experience with fully battened dinghy sails isn't that extensive, but I know that on a Merlin with a full-length top batten, kicker off definitely helps during capsize recovery. You want a soft leech to make it easier for the water to stream off.

Kicker off can save your mast if it its the ground in wavy condition.
If you got a VANG it doesn't change that much to pull or let the kicker and sten iq right you will never depower your sail enough.
If you got a simple GNAV putting it off is a good idea.
On my old Morrison 8 I could capsize and recover in less than 30 sec. Now that I have a Bieker 3 it's another story. I missed a race just because I was exhausted righting back my boat in 15 knts but wavy conditions. The self tacker was so short that the jib was always filling in .
It's really important that the first person in jump on the tiller and head to wind eventually by also pulling the main .

Coming form a 12' skiff background, with a bit of I14 and 16 experience just for good measure, we do it as follows
First of all me and my driver are 85kg each(approx 13 stone)
- pack kite away
- make sure jib is uncleated \ eased
- in a bit of breeze let the Vang off
- don't worry about the cunno
- put heaviest person furtherest away from the hull hanging onto the harness of the person in front
- as the boat comes up is it sitting away from the breeze or into the breeze
- if it away(mast on the Leeward side) keep pulling front person should try to put a leg (back on works best for me) over gunwale and almost can step in without getting wet holding onto the trapline.
- If mast is to the breeze GENTLY pull on the boat hope fully you can keep the mast tip a foot or so above the water( not enough to lift the boat and send you under and up the other side(Russian roll?)) but just enough to blow the rig around and then reread 7
- once ONE of you is in the boat try to get things sorted by grabbing main sheet and jib sheet to get the boat moving and for balance driving gets in grabs tiller and of we go once more.
We don't have shock cord(elastic) on the tiller you can steer by heel and sail pressure. We do have a LIGHT tiller, with twin extensions and a light rudder
I hope this helps.

I'm not too sure if it would be class legal on a 14, should be as its a development class but maybe attaching righting lines might help. We had them on the 5000 and if it wasn't for them we wouldn't have been able to right the boat in most cases. Seen a few 9ers with them too. Basically what they are, are lines which run along under the gunnels or parallel to them attached to shock chord. When not in use they sit tight against the hull. When the boat is on its side you use them to extend your weight further along the dagger board and set at the right length you can basically hang off the tip of your board (standing on it), enhancing the leverage you have to right the boat.

Righting lines like you describe are on the Laser 2000s where I work, think
they're standard. I can't imagine any class association is going to ban
them, if they did and there was an incident with someone not being able
to right the boat there might be some questions asked these days. Also
I don't see any major advantages (in racing terms) of having them.

Had to mention the class legal thing because I don't want to get anybody in trouble if their not. But it is a 14 so they should be okay

Actually on the 14 you just need to grab the spinnaker sheet on both side from the block and you have a wonderful righting line.
Unless you are more than 100 kg combined crew it's really easy to right back a 14 (I do it alone with 70 kg). The problem is to keep the boat right after.

That is what I've been using as a righting line. Even doing this, the tip of the mast will hardly leave the water without the crew on the daggerboard and I'm 70kg.

That's with the mainsheet off is it? That sounds more like the main
being full of water, cos if the hull's upwind and the masthead is only
just clear of the water the main should be in the lee of the hull
anyway. When the mast head's just clear, what position is the main in?

Could be. With the masthead just clear, the main is just floating on top of the water.
Tomorrow I'm going out again and have a few goes at righting the boat different ways with a rib next to us and see what works.

Ah, if the main is actually on top of the water it could be the surface
tension of the water holding it down, try lifting the main on its own,
and if that's hard try sinking part of the main, might help. If the
main is on the water it can't be a depowering issue, cos it won't have
any airflow round both sides (it's an aerofoil) so at worst it would be
like being on a dead run, which the hull will shelter.

A quick update for anyone this may help. I tipped the boat in over a sand bar today so we could stand and have a play at righting it. With my sister holding the boat into wind I could right it by myself.
I tried righting it without her holding it at all and she watched the rudder. As the boat starts to come up it is moving forwards a bit and the rudder is all the way over, making the boat bear off and power up.
Mystery solved. I guess bigger/tighter elastic round the tiller may help this.

Since the problem is solved ive got a question:
Why do all the 14s ive seen seem to have really long kite chutes, with
a kite that big wouldnt it be easier to bag it? do they get in the way
of feet etc?

On our boat the kite doesn't use up anywhere near all the kite chute. It mostly just keeps the halyard from getting tangled really. Seems to work ok, I've never tripped over it (yet).
