| Post subject: | Hobie 18 SX |
I have a Hobie 18SX. It has a comp tip, I don't want a comp tip, does anybody have an 18SX mast with out a comptip that they want to trade off for one that does? |

Was an 18 SX ever made without a comp tip? |

I'm not the Matt you're looking for, but I do know that the SX was introduced in 1989 - 4 years after boats came standard with the Comptip. Short answer - no. The SX never came with a solid aluminum mast. |

I was afraid of that. Does any body know who supplies Hobie with their mast. I may have to bight the bullet and buy a new one. The whole reaso for the mess is that I want to be able to control prebend and I don't think I can do that with a comptip. |

If you have a section of the mast and know the material, you can contact a custom aluminum extrusion house. It will not be cheap but you can get pretty much whatever you want in the constraints of thier capabilities (and your wallet). Maybe someone in Euorpe has an SX mast without the comptip? |

It would make no sense money wise to try to swap mast with someone across the sea. If Hobie has there mast extruded in the US then maybe I could get a bare extrusion for about a grand or so and just transfer all my parts. |

| Post subject: | Hobie Extrusions |
We do not sell bare extrusions for many reasons. We also do not have extrusions of that length. We run them to the cut length only. I have never heard a problem with the CompTip on an 18, 18SX or 20 related to prebending the mast. The tip is above the hounds, so even with an all aluminum mast you are not going to get bend up there any different than with the CompTip. |

http://www.hobiecat.com/community/viewt ... highlight= This old link may be of help, talks about spreader, diamond and rake settings. There obviously is not as much info (tuning) for the SX, but is very similar to the H18. We've found it relatively easy to flatten the main with downhaul (rules allow 8:1). Prebend, in theory, is useful (to keep the mast out of the slot, and main flat) if you move the spreaders aft and tighten diamonds to create fore and aft bending. We keep our mast upright (no rake), diamonds just tight (with spreaders forward) and flatten with downhaul. Your main is mylar, ours is dacron, and we weigh 305, may not work for you, but hope this and old link may give you some ideas to test out. Merry Christmas to all. |

| Post subject: | GONE CUSTOM |
Since a fleet of SX's will never form I am going to race portsmouth. As a result there is only a small penalty for aftermarket sails so I am having Ullman cut me a Pentex main and jib. There are the ones that said having an all aluminum extrusion was better. Since one is not going to be available they are going to design the sail with that in mind. I agree with what Matt is saying about the comptip being above the hounds but I guess they are figureing on some flex. It must make some kind of difference or the Tiger would have a comptip as well. Obviously if money were no object for me, I would have just bought the new Tiger that I really want. Oh well, maybe in a couple of years. |

Agreed, I think all you'll possibly see due to the comp tip (above the hounds) is some additional twist (compared to all aluminum). That is to say, a better way to bleed off the extra power you don't need in high winds. If it's a square top cut you're buying the advantage there is in light and medium winds and IMO the potential for flex/twist of the comp tip will not be significant in those conditions. |
