I was in a regatta this weekend and the rest of the pack kept pulling away from me beating to wind unless I headed off slightly (about 5-8 degrees) to power up the sails. As soon as I was up to speed I would try to get on course with them and I started pinching again loosing speed.
I’m wondering if I do not have my boat setup as best as can be and if anyone has any tips I can try?
Thanks in advance!

My thoughts, in order of importance:
1) Put telltales on your jib at 1/3 and 2/3 height about one telltale length back from the luff (front). Set up the boat before the start so that both telltales break at the same time (constant angle of attack). Concentrate on keeping the leeward telltale streaming and the windward telltale just breaking. You should spend 85% of your time watching the telltales.
2) Sheet in the main slightly. Unless it's really blowing you want the traveller right up.
3) How much do you weigh? Minimum weight is 295 pounds. If you are much heavier than this you must sail lower to make more power to push the extra water out of the way.
4) Change the mast rake, depending on your answer to question 3. More rake (2 or three holes on forestay) makes the boat point higher for equal weight, less rake (2 or 4 holes) powers the boat up for heavier teams.
5) We always used to set the side stay tension tight. Put somebody sizeable on the wire, on land, and lower the pin. We used to have that person "bounce" and the pin person pop the pin in at the bottom of the bounce.
6) Set the downhaul tight. Get right up by the mast and lunge downwards and then cleat it off.
7) Make sure the outhaul is quite tight for upwind. "Bowstring" it by cleating it, pulling sideways in the middle, then taking the slack out and cleating it. Repeat as necessary.
When you are just sailing, if you have a reliable training partner, point the same direction as them and then set the:
traveller
jib sheet tension
main sheet tension
downhaul
outhaul
go back to shore and reset the rake (repeat as necessary)
At a regatta you might ask somebody to come out ten minutes early and go through all that to make sure you know what your settings are going to be. A mark on the jib sheet and mainsheet is handy, particularly the jib sheet since you want your crew to reset it exactly after each tack.
Concentrate on keeping the leeward telltale streaming and the windward telltale just breaking. You should spend 85% of your time watching the telltales. I'm pretty sure this is your issue. You have to sail the boat down the groove as it shifts and wanders. The groove is only about 5 degrees wide.
Good luck! I just love sailboat racing. -

want to point higher, go faster and have more responsive controls without improving your sailing skills at all?
get new sails
epoxy and fair your boards (center/rudder) if needed
drop 15-25 lbs
put concrete in your competitors hulls

Ron,
First thing is WHO was pointing higher? Was it other Hobie 18's?
If so, then the advice above is good especially new sails.Make sure your rotation limiter is aligned with the boom as much as possible upwind.
If it was more modern boats with the newer extremely high aspect daggers and rudders and sail shapes then you shouldn't try to point with them.

Great info here guys! Thanks! I'll consider all the above while learn and look over my boat and compare notes.
Damon, yes they were walking away from me! Got my boat from someone who used it on the ocean only so boat was setup for heavy winds I'm finding out. Loose stays & diamond wires etc...

go over all the basics.
- rudder trim and alignment
- mast rake for weight, waves
- compare to another well sailed hobie 18
- need a good jib to point.... then it's got to be trimmed correctly..but not overtrimmed.
- main, trimmed too.
- faces down, rears up... more up... more... get it?
- less weight, better pointing.
you should be able to stay in or with the fleet (including new boats) to the "A" mark...
but after they launch the spin and go downwind..that's the last you'll see of them.

Do not pull the outhaul in "bow string" tight. You want to maintain draft in the bottom of your sail. I would recommend allowing the foot of the sail to blow off the boom about 4-6" at it's deepest point as a good all around upwind setting. Also, do not point the rotator in line with the boom. That is WAY under-rotated. The rotator arm should point somewhere between the outboard corner of the rear crossbar and the shroud.
If you're having trouble pointing and maintaining the same speed as your competitors, my first guess, without seeing you sail, would be that you are under-sheeted. Place a set of telltails on your mainsail in the second and third panel from the top. These telltails will tell you how much twist you have in the top of your main and if you can sheet in more.

Here’s a shot somewhere in-between a close reach and being close hauled. To me it looks like I have too much twist and am spilling wind. I was going to try to lessen the rake a notch and see if I get a better sail shape and hopefully it makes a difference.

Ps, I know about the wrinkles in the luff. The downhaul won't synch all the way because the boltrope near the foot keeps jamming up against the helper and this time I didn't catch it. Most times I do though.

Here's some reading material. if the link doesn't work, search "Hobie University"
http://www.hobieclass.com…nloads/hobieu/HobieU.pdf
I can't see the tell-tails in the photo but you are under sheeted for close hauled.
Downhaul.

Are you using the stock 3-1 downhaul with the cleat on the mast? The easiest way to vastly improve your downhaul is with the "Power Downhaul" 5:1 system, it can be added without any modifications to the boat.
http://www.murrays.com/07-2087.html
What condition is your sail compared to the boats that were pointing higher?
Fix whatever it is that's giving you problems at the foot of the sail, not sure what the "helper" is, crew?
The thoughts on amount of mast rotation upwind have changed over the years. When catamaran sailing in the '90's we pointed the H18 limiter at the shroud, but later the Australians started rotating the mast to be more in line with the boom. This makes perfect sense if you think about how that produces a smoother entry and lets the wing shape of the mast contribute to the sail area.

The boat came with a really nice Harken 6:1 DH.
The sail feels really stiff so I'm assuming not much use on it. No repairs, fading, or loose threads anywhere. Really nice condition! Probably more so than the 1980's boats I was trying to catch.
Sorry, "helper" couldn't think of the word "sail feeder" http://www.murrays.com/50-80100501.html
The boltrope clears the "feeder" by 8" then you have to pull it back down through the feeder and this is where it catches and usually bunches up. These things aren't really everything they're cut out to be...
I played with the mast rotation a little bit and didn't notice a whole lot. If anything I felt there was a happy medium somewhere between all the way out and all the way in.

I agree, you might want to lose that, no need to cause yourself problems. I've never had one, so can't judge, but I know you can raise the sail without one.
Realized that you aren't going to be able to tell a difference on any particular small adjustment like that unless you are racing side by side with another stock well-sailed Hobie 18. Even then we are talking about a a 2 or three boat lengths to windward at A mark, which is enough to win a race but probably not enough to "feel".
Tuning your boat without a match race partner is very difficult. Try having your crew read your speed from a GPS while you point as high as you think is correct. You may find you are pinching, footing, or over trimming sails more than you think.

Ron, WE will have three P-18's and three H-18's on the beach in Big Bear next year for a 7 Regatta series with 2 throw outs. Sol Cat 18's & Nacra 5.2 invited also--everybody racing even. Plenty of opportunity to tune! Pete -

That thing is worse than useless. Take it off, throw it away, and use the mounting screws with silicone to seal the mast back up.

Have you tried putting decals on your boat? Get an "R" pr "V-TEC" sticker and slap it on. I put a "Harken" sticker on my trailer, and picked up 33.2 hp.

WAY under-sheeted. This is far and away the primary problem. Again, put two pair of telltails in the upper panels of your main sail. They will tell you tons about how much more you can or can not sheet in.
You are also sailing the boat too flat. You want to try to keep the windward hull skimming if possible or at least have the leeward hull significantly lower than the windward hull. In light air, the crew will sit on the leeward hull or right at the edge of the tramp where it meets the hull and right up against the front crossbar. Skipper will sit either on the tramp just to windward of the mast or on the hull. In that picture, it looks like there would have been enough wind for you to fly the hull if you were sheeted in more heavily. Also, as you noted, the down haul is not tight enough. A couple little wrinkles in the leading edge are ok in light wind, but you've got some large wrinkles that need to be taken out. As said above, remove the sail feeder - it does more harm than good.

Dogboy is right. Way under sheeted. No where near enough down haul. Get forward, get crew leeward and it looks like you have little to no batten tension. Been sailing a Hobie 18 since 1992 so I know a little, not a lot. that is out of whack by a bunch. HTH, Richard.
