Posts: 170 Australia | Hey
On the weekend we finnaly had wind(30+) where i live and the first day (saturday) i took a kid out who weighed next to nothing say about 30kg and i weight 62kg. We capsized only once in 2hours which i felt was an acheivement since it was the first time this kid has ever sailed a hobie 16. We capsized on a close haul with the travelor all the way off and only the jib on and me still bering into the wind an we went over. The second day i went out with a person who weighed around the same as me and well we wen over 4 times in 30mins in the exact situation. I know i set th boat up different but dont know how i depowered my boat for the lighter kid. My question is how do you depower your boat and not lose too much speed and is there any thing i should look for when sailing in these winds. By the way im only 16years only and the crew was about 12 on satursay and 15 on sunday.Thanks
Jules

Posts: 123 Santa Fe, New Mexico | Dear Jules, I am not an expert, but over the past year I have finally come to realize that the powering down the jib sail in high winds is the trick. It sounds from your post that you powered down the main but not the jib. I have learned that the crew has an important job controlling the jib sheet. I used to think that I would tell the crew where to cleat the jib and that was it. Now, I know that I was wrong. They have half the power in their hands, and they need to adjust according to conditions.  Greg H14, H16 | | | Re: speed and power

Posts: 170 Australia | Thats for all the help. ONe last thing is, alot of people are talking about the jib halid tentioning of a way to de power your boat. How effective is it since i feel i allways need to have it on real tight.

Posts: 493 Minnesota | I agree with giving experienced crew near total control of the jib. I like to sail by consensus. I started sailing by crewing with a friend who had only a little more experience than me. I experimented with the jib, and soon was in total control with my "little" sail. I was more adventurous and I was the first to suggest we sail wing on wing. Sure its the slowest point of sail, but it was beautiful... oh, boy, that was years ago... Now, we just ask, "Do you want to run jib or main?"
I like to think of the jib as the 'turbocharger', and the mainsail as the 'motor'. Sure, all the power is in the motor, but when you kick in the turbocharger, all hell breaks loose. The jib, instead of forcing fuel/air in to the motor,... it forces more air to flow across the main. More air across the main...more power! When you are sailing up wind, try leaving the mail set to one position, ...then tighten and loosen the jib. You will see the difference. Of course, the situation gets a little more complicated at different points of sail. Get a sailing book from the library, and read about air flow.

Posts: 170 Australia | thanks but ive still got th problem of not being able to adjust the joib tention since thats the only thing the others have on me i need to know how to do it better? The other thing is if you have the side stays tight and the mast raked heaps back ive heard its not always the best since it slows your tack down heaps. in terms of nose diving im not too worryed since the only times i really have to worry is when the wind pushes above 25. No offence at all but i think a few people are showing their age and this is coming from me  but then again im only 16 so every one is old to me. Jules

Posts: 106 West Texas | Jules,
We sail heavy on my boat, around 350 lbs. I rarely ever have my crew on the wire, because I weigh 220, and she is a little timid when the winds "scream". In West Texas, we sail winds of 25+ knots frequently, so I have a lot of experience.
I agree with what everyone's advice.
Here is what I do:
I rarely ever travel out very far--6 to 8 inches on the main and 2 to 3 inches on the jib. I try to keep my travelers as close to the centerline as possible. It is critical that you tighten your jib halyard and downhaul as much as possible. The jib halyard keeps the angle of entry of your jib as straight and as flat as possible. If your jib sags, it cups...this catches the wind, and will dump you over. The downhaul on the main helps flatten the sail...depowers the sail.
The big trick is learning how to drive off a little (accelerate) before a gust hits, then pinching up with the gust to take the bite out of the gust. Once you learn how to depower your rig, the rest is helmsmanship. Good crew is critical in tacking and helping manage your jib.
Now that I said we sail heavy. I often sail my boat in extreme winds solo. I will travel my jib out further, because I have a hard time working both sails. Tacking is a bear solo, but it can be done.
Keep on practicing, Young people have the advantage of quick reflexes and agility,

Posts: 123 Santa Fe, New Mexico | Jules, 2.2 pounds = 1 kilogram. Please now answer this for me. In Australia are your next three months called the Fall or Springtime of the year? Old folks are sometimes pretty ignorant.  Greg H14, H16 | | | Re: speed and power

Posts: 170 Australia | ok i get that but the major thing is we're kind of light (120kg)so when th winds come in around 25+ the jib is enough to capsize us. If we have the travelor at the hiking straps and if we get hit by and BIG gust should i let the travelor out and pull it back in because i've heard a YES/NO answer.

Posts: 106 West Texas | Jules,
When I cannot get my boat to settle down; that is, I cannot keep it with the windward hull just touching the water a large percentabe of the time. I will travel out a little, until I feel like I have control of my boat. Going upwind, you will always want your traveler as close inboard as possible. When you travel out it changes the angle of attack of your sails to the wind; therefore, you cannot point as high. You have to learn to watch the gust and drive up into them; this is tricky, because if you drive to high, you will kill your power or tack un-expectedly.
With time, you will notice that usually before a big gust, the wind will lull a little. This makes boat handling tricky. I always drive off in the lull, to keep my boat speed up, wait for the leading edge of the gust; if it is a lift, then drive up to find the grove; if it is a header, then you are in the position to drive off with it.
When the winds are gusty, learn to sail with your traveler in as close inboard as possible. I will ease my main, when I miss read a gust, and it starts taking advantage of me. I never work the traveler going up wind, except when I need to let it out a little to help me handle my boat better.
When I sail my boat solo, I will travel my jib way out and sail on the main only. I will keep my main traveled in close and adjust for the gust by easing the sheet.
You should keep in mind that sailing a Hobie 16 is like sailing a mono sail boat. The jib is most useful when it come to tacking. If you sail too far off wind, it can flip you over.

Posts: 170 Australia | I think ive got the magor idea but its still the small bits that puzzel me. Like isn't it quicker if you use your travelor that the main sheet. I saw alot of people doing that in melbourn commenwealths.
