Posts: 22 New Jersey | I sail P19MX too. I sailed my boat with a spinnaker before upgrading the sails. I have come to the conclusion that if You want to sail the MX rig with a spinnaker forget about the big Jib and go back to your old jib or sail it without a jib. With The MX jib the tack is so close to the deck that the pole could dip in the water when you were sailing

My crew and I just set up a snuffer rig on his P19MX. Have only been out with it one time and it worked great. After a lot of measuring and trying to figure out the best way to do this, we finally decided to "trim" the MX jib. We basically took a slice off the bottom. Held the clew where it was, (in fact didn't even have to replace the grommet) and shortened the luff by raising the tack about 12-13 inches. Yes, you lose a little sail area (about 3 sq. ft.), but have the advantage of the snuffer spinnaker. By doing this we held the location of the pole up out of the water (where they recommend it) and not subject to dipping it as badly as if you lowered it to the same spot as the bowsprit. This seemed like the best way to do it. Be glad to send you some pictures when we take it out next time.
I asked Randy Smyth the best way to do this. He has used a spinnaker with his MX, but it wasn't a snuffer rig. He pretty much replace the bowsprit with the pole and used it like that. Of course he was launching the spinnaker off the deck. One suggestion was to offset the pole on the front crossbeam, but hold the tack end in place. This looked like it would work, but sure wouldn't have been pretty. There is something to be said for being symmetrical.
I know exactly what you're going through trying to figure it out. Be glad to share the info anytime.
Let me know if you want to discuss.

Posts: 3,116 Annapolis, MD | I have been helping Harry Murphey with his MX conversion to a chute. He has the max mast rake he can get as per Randy. Then he had Randy build a smaller jib with the chute in mind. he uses a Nacra 6.0 bridle foil to stiffen the boat His pole will attach just under his foil and be sufficently high enough off the water for using a bag and later on a snuffer of some kind.
His thinking is that he will have optimized his upwind, reaching and down wind performance by loosing some of the jib. He also noticed that the Nacra 6.0's were not furling their jib with a Smyth chute so he ought to be able to carry all three sails.
Let me know what you decide so that I can pass your solution on to him.
take care

Posts: 364 | That's how I run mine. I have a two-piece carbon pole which I run about 6" below the forestay bridle, and bend the tip down several inches with spectra lines back to the bows. I have a 12' pole and run an F18 chute sheeted to the main beam. Not surprisingly, I'm looking for a slightly larger chute. I plan to be at the Galveston Bay Chute Out on October 12 that Scott Tuma is organizing. He's the P-19 guru for the area, and may even have his boat there. I am running the halyard a lot like the new Tornado rig, with an eye almost at the masthead and a block on a 20" spectra leash which is free to run on another line attached thru the luff track to both sides of the mast. This forces the mast to rotate when the chute is up and solves the main problem with the typical spinn tangs, which try to de-rotate the mast.
anyway, good luck, and hope to see you at the Chute Out.

Posts: 3,224 Roanoke Island ,N.C. | I ran a 15 foot pole with a 460 sq. ft chute on my P-19MX. I used a strut under the bridle to hold the pole down and then tied the jib off to the pole. The pole was carbon with spreaders under it. It was low to the water, snapped it once in a post hurricane swell during a New England 100. After that I ran a piece of Spectra from almost the end of the pole to the highest point under the jib luff and tied it off to form a preventer. The extra sail area is awesome ,it's a shame to reduce it.
