1805.0. "Rig for Spinnaker" by STAR::PROULX () Wed Oct 16 1991 23:26

    After several years of racing in cruising divisions and watching the
    racing classes get knocked down, wind their spinnakers around their
    forestays, get them sucked under the boat and other adventures we
    decided it looked like so much fun we'd try it.  My husband, Larry,
    bought a second-hand spinnaker and we actually used it once,
    successfully, with just a two-man crew, but now we have some quetions
    as to the proper way to rig the boat for its use.  The trial was with
    sort of a jury rig (i.e., went up mast and pop-riveted padeye to face
    of mast above forestay to hold temporary halyard block.
    
    The boat is a 26-foot, 7/8 fractional rig.  We use a hank-on jib and
    presently have only one jib halyard, although there is a second sheave
    in the mast.  Halyards are internal.
    
    First qustion:  The spinnaker halyard has to terminate above the
    forestay.  We could cut a hole in the mast and install an exit 
    sheave for the halyard and run the tail inside the mast with the
    others.  But - the top of the mast takes a lot of stress when the
    permanent backstay is cranked on and cutting another 1" X3" hole 
    for another sheave box is a little scary.  Also, the lead is never
    very fair - both when hoisting and sailing the halyard is pulled
    to one side.  Would my should I just stick with my padeye and
    block and external halyard?
    
    Second:  regarding the foreguy;  Some diagrams I have seen show it
    being run to a point near the tack fitting on the stemhead;  
    others show it led to a block in the center of the foredeck, right
    where you will trip over it or be stabbed in the back sunbathing.  A
    friend who sails a small one-design boat says run it to the base of the
    mast so you can play the pole without constantly readjusting the
    foreguy, but doing that makes it so it only pulls down, not forward,
    which I gather is supposed to be part of its function.
    
    About the topping lift - could I use the spare jib halyard sheave?  It
    would hve to be wire.  If not, how is it usually done?
    
    Lastly, how about suggestions on where and how to terminate the new
    control lines for best function and convenience.
    
    My winter project will be to install this stuff so we can go out and
    compete for a Sailing World Embarassing Moment photo next year.  Any
    suggestions would be most appreciated.

1805.1CRATE::BARKERNow @NEW, ex. RYO,UCG,SBP,RES & REOThu Oct 17 1991 06:0740
    Welcome to the world of multi coloured Nylon.
    
    The choice of how to rig the pole depends on how you are going to gybe
    the kite. The best way to do it on a 26ft fractional rig boat, would be
    to end-for-end it, that is, when you gybe, you first disconnect the
    pole end from the mast, then attach that end to the old sheet, you then
    disconnect the other end from the old guy, and attach it to the mast.
    
    If you do this, you will need to attach the uphaul and downhaul/foreguy
    to the centre of the pole ( or to the centre of a wire going from one
    end of the pole to the other ). You also need a symmetrical pole. The
    downhaul should be lead somewhere on the foredeck, the further aft the
    better. I have sailed on a boat where it runs through a jamming block fixed
    to the front of the coachroof, which is about 3 feet in front of the
    mast.
    
    If you attach the foreguy/uphaul to the end of the pole, then this end 
    has to be attached to guy, and the only way to gybe is dip-pole, which
    needs more gear, and more crew.
    
    Regarding halyards, there is nothing wrong with leading the halyards
    externally, although one possiblity dependeding on the exact design of
    the sheaves, would be to run the halyard though the second jib halyard
    sleeve, and then though your block above the forestay. You should only
    do this if there would be no friction.
    
    A second possibility, which is how our Scampi is rigged, is to cut a
    slot in the mast, about 2 feet BELOW the forestay, (fitting an insert to 
    stop the sharp edges rubbing ), and then take it through the block
    above. I would agree with you about not cutting the mast above the forestay.
    
    The pole uphaul needs only go 3/4 of the way up the mast, and can
    easily be led externally or internally. Lead all the ropes aft if you
    are serious about your racing, otherwise just have cleats on the mast.
    
    Good luck,
    
    Chris
    
    
1805.2Suggestions from a cruising sailorACTHUB::RYANThu Oct 17 1991 15:2840
    Having just done this for my cruising boat, a Catalina, here are some
    suggestions:
    
    1.  It costs more than you think - even if you do it yourself.
    
    2.  You don't need all the fancy racing extras even if you do some PHRF
        racing.
    
    3.  Use an external halyard or go through the extra jib halyard. 
      
    4.  Run the guy from the base of your mast: I didn't do this, and on my
        small boat, the padeye and block always get in the way.  Maybe you have
        better control of the guy but I doubt it. 
    
    5.  Use your jib halyard for a topping lift as long its not in the way
        of the halyard.  If it's wire you should change to nylon
        line to eliminate any chance of fraying coming in contact with the
        chute.
    
    6.  For #3,4,5 - the layout to the cockpit is more important than the
        internal halyards, extra topping lifts, etc.  Use color coded lines
        if possible to minimize confusion.  Spend the extra dollars here.
        Use 'deck organizers' to channel your lines to the cockpit.  Think 
        about this carefully.  
    
    7.  An inexpensive way to mount sheet blocks is with fittings that
        attach to your stern pulpit stanchions.  Using the genoa blocks
        works pretty good (some binding).
    
    8.  Buy a turtle bag for the chute.
    
    
    I single hand the boat (with a tiller tender) or minimally short-hand
    sail the spinnaker with a crew working just the tiller.  The only
    things I'd change would be COLOR coded line (not just speckled colors)
    and moving the guy to the mast foot's bridle.  Spinnakers for cruising
    aren't all that hard to fly as long as the boat is intelligently layed
    out and you stuffed the chute correctly the first time.

1805.3topper adviceAKOCOA::DJOHNSTONThu Oct 17 1991 15:598
    If racing, you absolutely need a separate topping lift from the jib
    halyard.  Otherwise you need to lower the jib  everytime you raise the
    chute.  This is not good practice.  It is slow if you are racing and
    hard to control the chute even if cruising.  Take downs without a jib
    up to blanket the chute are even harder.  The topping lift can be wire
    and will not chafe the spin anymore than braid.

1805.4This will Complicate things further!NZOMIS::MITCHELLGlen M. - The Kiwi ConnectionFri Oct 18 1991 09:3049
    I have a 25' Trailer yacht used exclusively for racing.. we carry a
    crew of four and always sail with maximum sail area available with a
    choice of two kites. 
    
    My rig is also fractional, but with swept spreaders and no backstay,
    and we have the option to use running backs which I rig for long
    distance races, and remove for round the bouys stuff.
    
    A couple of other points you may wish to consider:
    
    1)	you wont have much room to store your pole... we used to keep ours
    on the boom in largeish rings, and this seems quite common with both the
    topper and down haul left attached... this often caused problems on the
    beating leg with the attached lines sometimes catching on cabin top
    fittings such as winches or "open" clutches. We did away with the Boom
    idea, and have far more success stowing the pole on the deck running it
    fore and aft from the base of the mast.. 
    This system also has its pitfalls, but when racing with a reasonably
    experienced crew works better for us.
    
    2)	As an additional feature to add to the complexity of tuning and
    performance options, our spinnaker halyard actually exits above the hounds,
    and travels up to the mast head, where it passes through an external block,
    and is then tweaked down to a position just above the original exit
    point. The tweaker can then be eased to fly the spinnaker from the mast
    head, or taken in to fly the kite fractionally... Our mast was
    therefore designed to have two exit holes above the forestay (and in
    the tapered area), one for the halyard exit, the other for the tweaker.
    
    3)	When racing, I also believe its useful to have spinnaker sheet and
    brace long enough so that they go right around the boat. This means
    that if you cannot, or elect not to, ping the snap shackle on the brace
    when dropping the kite at the leeward mark, under pressure you can
    always safely run the brace instead.
    
    
    4)	 Do you have tweakers on your sheet and brace?
    
    Complicated options eh? but keep it simple at first... we learnt to
    sail by racing, and were thrown in at the deep end in conditions where
    the normal wind strength is 20+ knots.. and in those conditions
    spinnaker work can be pretty exhilerating for the novice to say the
    least.
    
    Good luck.
    
    
    3)	
    
1805.5Downhaul placementPOBOX::DBERRYThu Oct 24 1991 17:097
    I would not attach my downhaul to the base of the mast unless I were
    only gooing to fly the chute in very light air.  The load on a downhaul
    under some conditions can be considerable and would be aggravated by
    the attachment to the base of the mast.  People don't put those blocks
    in the middle of the foredeck (right in the way) just so they can spoil
    the sunbathing.
    
1805.6dual downhaulMDCLAM::WARSHAWThu Nov 14 1991 17:457
    As a crew member working the main, I am sometimes required to help with
    the chute lines. I found that the dual foreguy (port - through block on
    pole- to starboard) saved me lots of time travelling port to starboard.
    
    It's worth the extra bucks  without full crew.

--------------------------------------------------------------------------------
    
    
    I've developed a case of "spinnak-a-phobia."   I wonder if anyone out
    there reading this shares this dreaded disease.
    
    Being cruising (not racing) sailors, a few years back we got ourselves 
    a Cape Dory 28...full keel...etc.
    
    It came equipped with a spinnaker, spinnaker halyard, pole, block in
    the middle of the foredeck (for I foreguy, excuse if I use the wrong
    names), blocks for the sheet and afterguy...etc.
    
    I've flow it perhaps 3 times...the last time about a week ago.  In the
    past, I lowered my jib, and then spent 20 min on the foredeck getting
    everything arranged, and never felt like I was "in control."  
    Now, this time, having watched the America's cup mark roundings, 
    I knew just what to do?  I set everything up, and successfully raised 
    the spinnaker behind the genoa.  Dropped the genoa, and IT WORKED!
    It filled up and looked right (to me).
    
    But this lasted only 3-4 min.  It took me about this long at the helm
    to manage to wrap it hopelessly around the forestay.  Spent the next
    20 min working this out.  Lowered the spinnaker and headed for the
    barn.
    
    Now "spinnak-a-phobia" has settled in.  SPINNAK-A-PHOBIA:  a fear of
    flying chutes.    
    
    Any suggested cures?   
    
    Maybe the first step is to admit your a "spinnak-a-phobic."????
    Am I alone...should we form a support group?  What should we call
    ourselves?    
    
    
    Seriously, your suggestions on how to go up the learning curve with
    minimum pain are welcome.

    The only cure that I know of is ... practice.  Try to do it on a day
    when there's moderate wind (over 5 kt, less than 15 kt).  If possible
    take an extra crew or two along ... preferably someone who knows how to
    raise and douse a chute.

--------------------------------------------------------------------------------
    Here's an exercise to build awareness of how the wind and chute
    interact.  Launch as you are accustomed to doing.  Position the pole
    halfway between the forestay and shroud at a height that puts the two
    clews on the same level.  If the pole tends to bounce, put a snatch
    block on the guy at the widest part of the boat.  Trim or ease the
    sheet so the chute looks "right", i.e. not collapsed or wrapped. Then
    cleat both sheet and guy down.
    
    Make sure there are telltales on both shrouds.  Then, pretend the chute
    is a big jib.  Head upwind till the chute's leading edge starts to
    flutter and then, fall off to refill it.  Fall way off and watch the
    chute wrap neatly arond the forestay.  Using the telltales note what
    the wind is doing W/R/T the chute.  It will become apparent that wind
    hitting the backside of the chute, whether from heading too high or too
    low is bad.  
    
    The big trick in chute handling is too keep wind flowing into the belly
    of the sail and away from the backside.  Just manipulate everything to
    make that happen and you'll do fine.

    Can't resist a story here- back a couple notes someone mentioned the
    foreguy -or whatever its called.
    
    I crewed on a Concordia Yawl in college days. On one race there was a
    lot of confusion on a jibe, and several different names were called
    out- foreguy, pole downhaul, etc. The skipper, in a bit of a fit said 
    "I dont care if you call the damn thing George, just someone pull on it"
    From that minute on that line was called George, and it was the one
    line on the boat everyone knew.

    	I've never tried one, but how about those chute-scoops? It's
    	a long sock you pull up and down over the chute with some simple
    	mechanics- probably not too expensive- and you can operate the 
    	thing from the cockpit.
    	It won't prevent wraps altogether tho. Not even a full crew can

re   .7  Spinnak-a-phobia


While you are still learning to use the spinnaker, leave a working jib/yankee/
whatever, hoisted high (strop if necessary) and sheeted hard in. That way the 
spinnaker will not wrap so easily and its MUCH easier to unwrap because its not
tight round the tight around forestay wire . The jib doesn't cause too many 
problems with the air flow while you learn to set it.

The other useful thing to try is to use the forces that wrapped it to un-wrap 
it. (You see I'm a lazy sailor as well as a bad one!)  Let's assume you
launched the chute and got it up clean, pole set etc. Then a moments inattention puts a
twist in it. Before it wraps around 66 times, jybe the main asap and leave the 
pole on the wrong side (tell your crew before you leave the dock that this is 
what you will be doing IF the spinny wraps) . Steer to re-fill both halves of 
1805.14a few hintsBTOVT::HILTON_Gthe light at the end of the tunnel is an Oncomming..(crunch)Sat Sep 05 1992 03:02102
    
    hi,
    first off DON'T PANIC. It's ok to worry but don't let
    your fears run your life.
    
    I race semi-professionally and cruise quite often.
    I LOVE MY 'CHUTE... It's really not hard to fly.
    It's hard to fly right. But you don't need to be
    great at it to have fun and use the beast.
    
    A few hints:
    As stated, get 2 people who have done spinnaker
    sets, take-downs, jibes and straight flying. 
    (if your in the new Elgland area I'd be happy to
    drag my fore deck crew and spend a day with you)
    Pick a nice light air (NOT to light) day.
    
    Pick a spot for a nice long run. (a 20 , 30 run
    would be nice)
    
    lock the pole to the mast about shoulder height
    Keep the JIB flying until the spinnaker is full!
    level the pole by adjusting the fore-guy and 
    topping lift. 
    
    make sure the chute has been packed correctly
    (I assume it is)
    
    Set a single set of line (sheet and guy) don't
    bother with lazy guys
    
    set the guy and prefeed the guy so that the spinnaker
    is pulled up to the pole.
    
    keep the sheet tigher than it normally should be and
    raise the chute quickly.
    as the chute fills ease the sheet until the sail is full.
    
    drop the jib and make final adjustments
    
    ******
    
    When flying the spinnaker don't keep it too tight.
    most beginners tend to fly a spinnaker tight.
    this is ont goodness.
    Fly the chute 'open' let it have enough sheet.
    Keep the pole around 90 degrees to the wind until
    you get a bit better at tuning.
    Let the outside edges lightly flutter.
    
    If the upwind side begins to flutter or droop
    then bring the pole forward a bit.(if the wind
    has shifted) otherwise... tighten slightly
    on the sheet. Also if you get a puff let the chute have
    some room by releaseing a bit and then tightening the sheet
    as the puff drops off.
    
    Normally let the sheet out until the chute flutters and then
    bring it in just a bit. (remember , not to tight)
    
    As for crew, you should have three people for best results
    one to fly the chute (handle the sheet and call adjustments)
    one to handle the guy
    one to winch

    Take downs.  (THIS can get nasty)
    Normally, again this is pretty strainght forward
    if done correctly.
    
    Get a crew member not doing anything to grap the
    sheet between the sail and the after block.
    
    make sure the haylard is clear and not tangled
    
    as you release the haylard pull in on the sheet and
    pull like mad. At the same time have the person on the
    sheet (the person who was flying the chute) drop the
    sheet and assist in sucking in the chute into the
    cockpit or even down the hatch below. Have the person
    on the guy fees the guy around until its lose and the
    chute is being dumped. Then have them feed the haylard 
    until the chute in inboard.
    
    Ta DA!!!!
    
    you have set, flown, and dumped the chute,....!!!
