  • traphappy90 inches. BTW Catfan57 loved every second of our Peter Pan rendezvous at the front of the boat!


    Yeah, I'd say the "rendezous" at the $17 bare aluminum spin pole verified it was/is in fine shape and not corroded in the least, considering it came out completely unscathed. But my 195 lbs, hitting it at full force, probably would have been enough to prove the point - not so sure the pole, or my shins, needed an extra 225 lbs (being generous here) slamming in right behind to verify the experiment. But sure glad to know you're meticulous about testing out your equipment - so you can report the results on thebeachcats. icon_wink

  • Hey dssaak. While I haven't spoken directly to any of the club officers about it, recent emails from them say that they hope, and in fact are planning, for the club to be back to functioning normally this year, with full sailing activities. So they have posted the club's calendar (see here: http://www.fleet250.org/cgi-bin/calendar.cgi) with full activities, including that they are showing the 2021 Statue race scheduled for 7/4/2021, with a makeup date of 7/5/2021. So I think the best I can say is that the club officers are planning for the race, along with all other planned activities. But obviously that assumes we don't get "the man" coming down on us and disrupting plans based on some covid crap. I hope that answers the question as best as possible. Basically, I'd say plan on it, but stay in touch in case some douche bag in authority brings down the hammer beyond our control.

  • So I've made some progress on getting a Carbon Windsurfing Mast Setup as the a side pole snuffer. I tried to use most of the same hardware from the stock pole, but I'm looking for a couple more details, images and advise on the following:

    1. Any good advice on how setup the tack/halyard line pully at the end of the pole. With the stock pole the sail is just shackled right to the stainless hoop on the end of the pole, but in a lot of the F18 pictures I've found there is a separate tack line that is also continuous to the halyard with bungies that take up the slack? I'm trying really hard to figure out how all the works and where the lines all run.

    In the pictures below, if you click on the pic, it will show you the full size image.

    One option for the hardware at the end of the new pole?

    2. What angle should the snuffer hoop set at relative to the horizon? (Red lines in the pic Pic)
    https://www.thebeachcats.com/gallery2/main.php?g2_view=core.DownloadItem&g2_itemId=134552&g2_serialNumber=4

    3. On some of the newer F18 boats I see a little support line that supports the snuffer hoop. Is that typically used (blue line in the above pic) How does the blue line attach to the snuffer pole? Currently the side hoop sock has no attach points to receive a line.

    4. Does the Spin sock rear attach via bungies to the dolphin striker? Obviously I need to repair the top bungy that has previously snapped with the original owner

    After looking at all my current setup and fit check pics, if anyone sees something totally wrong or dumb, please let me know or point me to a picture of the right way to setup/rig a side pole hoop. The album of photos is uploaded to the Beachcat Photos page here:

  • I found this picture in the Nacra F18 Assembly Manual that shows a support line that goes from the bridle tang to the side snuffer hoop, but no details or close up on how the side snuffer hoop is attached to the line. Anyone got a close up shot of how the line attaches to the hoop?

  • Here is how I have the new Spin pole supported under the old style bridle bracket. Does anyone have a more elegant solution then this, or is this good with enough pre-load on the bridle lines to keep pole snugged up against the "soft loop"?

  • Hoop angle is correct. You may attach support line in one of two ways: 1) tie to pole just forward of hoop and tuck line into hoop groove. 2) drill hole in hoop and secure line by tying a knot inside.

    The spin pole should run through the bridle ring. The correct elevation at the tack, and steadiness in the pole, is achieved by applying tension to bridle lines and bend into the pole.

    The fittings at the end of the pole should be clean to avoid ripping the spin.

    The the loop in the back of the spin sock is not for attachment to the dolphin striker. It is for the spin retrieval line to pass through. This prevents the spin from being pulled out the back of the sock. Sock attaches to boat via grommets in rear corners.

    There are multiple ways to rig the tack and retrieval lines. You can rig it so the tack comes out or snuffs automatically. An advantage of this setup is that if line lengths are correct, the retrieval line does not need to loop to the back of the trampoline. Much cleaner tramp.

  • I am updating the pole on my I20 to have a bit less pre-bend. The hardware used on the current Nacra 18 and 20 work nicely. I will provide part numbers if you message me. 5/8 aluminum rod is used. The pole will be tied to the bridle mounts for additional stability.https://www.thebeachcats.com/pictures?g2_itemId=134598 https://www.thebeachcats.com/pictures?g2_itemId=134595

  • Hello, like you I’m restoring an Inter 20 (in Scotland) having owned one ages ago (fantastic boats). Would anyone by any chance know what the length of the spinnaker pole is supposed to be? The boat I have purchased has half a pole, which in my experience is a common phenomenon! Thank you, Jamie

    Jamie! They are sweet boats! They can float me and a bunch of kids, its great.

    I cut my new windsurfer mast to match the length of the original end-pole snuffer setup. The Spin pole is 143 inches long, and the spinnaker tack pully is mounted 1.5 inches from the end of the pole, so its at 141.5" from the cross beam.

    What all are you doing to "restore" your I20?
