Nacra 5.2 Spinnaker Questions  Bottom

  • Good day fellow hull flyers. I have a couple of questions regarding a spinnaker setup that I would like to install on my 79 5.2.

    Currently I still have the single spreader bar on my mast. Spoke with Mark at the Cathouse about an upgrade and all is well there.

    So my questions are:

    What type system should would be best to run; Front end or midpole snuffer system, also where do I locate the items. I have spoke with a friend on Catsailor forum and he said he installed a setup from a Inter 17 and works great does anyone know where I can just buy a complete system (hardware and such, not sail itself;purchasing a sail from Whirlwind)?

    How does the bottom of the spinnaker go from the midpole ring to the tip of the pole during launching? Also when returning the spi to the sock how do you keep your halyard cleet from grabbing while pulling on your retrieval line?

    How far down do you mount your spinnaker tab on the top of your mast?


    Any pictures and the process of how all this works would be great. I will not be racing so class legalities are not my concern just something for my wife and I to have fun with while downwind. We have been sailing for almost 3yrs now and love it.

    Here is a picture showing my Cat and how it is setup now.

    Here is the system I have in mind.

    this is the set-up I put on our nacra 5.5 - pretty close to what vernon "gree" has on his 5.2

    works really well and is simple for crew to put up and down

  • Can you tell me where you got your Front End pole from or where to locate one.

    Thanks

    this is a good link to a 5.2 set-up

    all the parts you can get from murrays

    I found our pole and snuffer system on ebay

    Good Luck

  • Bringing this post back from the dead! I was wondering if there was a more complete set of pictures of the setup?
  • I'll check my 'archives' tonight for you.
    What specifically do you need. I have some diagrams of my setup and can probably answer most of your questions based on my boat. I only added my spinn this year so its still fresh.

    Hi dennis! I have only gained a conceptual understanding of it all. Pictures showing line routes, block locations, snuffer specifics, I guess any measurements would be helpful as well. If more specific questions will make your answering easier I can post some soon! Thanks again!
  • Turns out I don't have any decent pictures of the setup. I do have my spinnaker pole and such in the house so I can take measurements if you need them.
    I uploaded a detailed schematic of my setup.

    I have a small spinnaker, I believe it is15.3m2. The sheet blocks are simply attached to the shrouds and are not auto ratcheting. This works, but auto ratchets would be better, especially in light weather because they allow the slack sheet to feed out properly. Now I reset the ratchet if I think of it or just yank it through the block by hand (the slack end, that is). The sheet turning blocks on the front beam are simple blocks with no ratchets. You may need auto ratchets there too if you end up fitting a huge spinnaker or want to fly the kite when its howling...
    The snuffer is a mid-pole system with the hoop just about a foot ( 25cm) in front of the forestay bridle and jib roller. The pole is an old windsurfer carbon mast which had a broken foot. I got it on the cheap years ago, it works very well, is lighter than aluminum and looks gorgeous!!
    The snuffer and pole are all held up by oversize (4mm) dyneema lines. That made it much easier to set up and change stuff around. It also hurts less when you accidentally scrape against those nasty bridle wires.

    The spinnaker pole is stayed from the tip to the existing bridle attachment points on the bow. I didn't fit any new bow attachment points for the pole but simply rigged the tip of the pole to the existing toggles using a couple of extra "D" shackles. There is also a pre-tensioner line that pulls the pole up to the jib furler drum and this force is balanced against a couple of mid-pole stays that also go to the bridle attachment points. This makes the pole assembly so rigid that I can actually lift the boat up by the spinnaker pole without the pole inverting or anything breaking. Apparently this is non-standard, so be careful when trying this out on any other boat as something may break. Kudos to the old and thick-walled windsurfer mast!

    The other interesting bit is that this is a single line system which allows you to pull up and douse the spinnaker using the same line. There is also no tack line and I don't miss it either. Ihave three rings in my spinn and this allows it to fold into the snuffer bag with nothing sticking out under the tramp. I don't have any turning blocks under the beam. The halyard/retreival line exits the back of the snuffer bag under the beam and is only slightly deflected by the beam. There is one eye I made in the tramp just beside the tramp pocket about 4" (10cm) in from the beam, the dousing side of the halyard surfaces there, goes on to the carabiner and back to a new cleat (oversize harken) with a big fairlead over it to allow the dousing line to slip back over it without catching while dousing. When raising this clamp is used to keep the spinnaker hoisted.

    I won't walk you through the whole thing now, I gotta go. If you have any more questions then just ask.

    Dennis
