| Post subject: | Sweet 17 Article from HOTLINE |
I am working on a project for the next HOTLINE and I came across this article written in 1988 by Wick Smith. Part 1 is here Part 2 is here PDF format - scans are not the best, but it keeps the file sizes down. |

Matt, Thanks for posting this! I just replaced my 16 with a 17 and this is helping me out a lot. My only question is when was this written? Not that it matters. |

It appeared in two issues of the HOTLINE in 1988. I haven't read through it all, but I did notice a couple of things that weren't 100% up to date. For example, most everybody now uses a self-tacking positive mast rotation device, not the single hook thing shown in the diagram. |

Matt, Thanks. I would like to find out more about the mast rotation device you are talking about. I'm curious about your project too. Is the Hotline making a comeback? P.S. Congratulations on taking Nationals! Doug, Thanks for the offer. I will e-mail you. I have Rick White's book and have read the section on 17's. |

| Post subject: | Mast Rotation |
I bought a mast rotator arm for a boomess from Murrays that is Like a V going out from the mast and straight across the back. I use the system for a Hobie 20 with two snaps rings, three pieces of line and shock cord. Tie the line across the bridle conncetors at front of beams. Then with line tied to holes in mast rotator I clip one end of shock cord to rings and loop it around front line and back to rings. This pulls mast forward for downwind to 110 degrees. For mast rotation I have a small pulley system with cleat that attches one end to boomand other to mast rotator. This sets mast rotation. Hope this make sense? If not call me.

The HOTLINE has made a comeback: 
It's in the mail now. Doug is describing the full set-up from a 17 Sport point of view. The Sport, being boomless, does not come with a mast rotation control. The 17SE (racing version) has a boom and the mast roation arm, with the control line to a cleat on the boom. The self-tacking setup is shown below: 
The system is made up of an 8' length of 1/4" elastomer (like solid surgical tubing available at http://www.apsltd.com), with eyes formed in each end using hog rings (the stuff will not hold a knot). Arrow 3 points to the elastomer. Put a Harken micro block on the elasomer. (Arrow 2) Each end of the elastomer is pinned to the bottom hole in each forestay adjuster, so that it stretches across the boat. (Arrow 1) Take a piece of thin (2 mm or less), low stretch line, tie one end to the vertex of the mast rotator arm, lead it out to the micro block (centered on the elastomer) and back to the other side of the mast and tie it off to the vertex, pulling a lot of stretch in the elastomer in the process. You can see how much the elastomer is deflected in the photo. Because of the difference in lever arms of the small line pulling on the vertex, the mast will always stay fully rotated to one side or the other. Mast rotation when jibing is not a problem - upwind, you usually have to give the boom a shove to get it to rotate to the other side in medium to light air. |

| Post subject: | Great Photo |
Matt: Thanks for photo. I just reccomend they get the mast rotator shaped like a V for a boomless. It works so much better than the stock one.

You misunderstood Doug - the H-17SE comes with the V-shaped rotation arm - in fact it's the only one allowed for racing. BTW, you may not want to put your phone number and e-mail directly in your posts (use (at) instead of @). There are software bots that harvest those things from forums like this. You'll have more spam than an Hawaiian! (Where Spam is still a breakfast favorite.  )

Matt: Thanks for tip on email address. I bought a 86. Guess the old ones had a different shaped arm. I had to buy new one. Doug |

Yeah, the early 17 Sports were . . . different. After a year or two, they made them more like the 17SE. More common parts. |

| Post subject: | 86 SE |
Matt: Mine was a SE, just a 86.. I bought Sport Sport system so I could add a reacher. 190 sq ft to go with squaretop. Both Pentex. use to race Portsmouth. Know anyone who needs a 14? One on Ebay. No reserve. Doug |

Gahh! That one looks rough. I smell shenanigans with those inspection ports. A no title in Texas? Good luck - I've heard what a horror story it is to get a title on a boat in Texas. A 1980 (if it is an 80) is probably heavy. You could fix it up and give it to the kids. |

Matt, Thanks for taking the time to explain this to me! The picture makes it perfectly clear what you are doing. I happen to have a piece of elastomer the right length for this. I'll have it on there today. The new issue of Hotline looks great! I hope it's more than just a name change for the class magazine, but that it also follows the format of the old Hotline... full of tips, tricks and feature articles. I look forward to sailing with you some day. J.P. |
