Posts: 297 | 30 years ago I flew for a charter company out of Boston. The owner wanted to buy a Lear Jet. Well, nobody puts "names" on their Lear Jet, (this ain't WW2) so instead he put their wedding anniversary date on the tail as the official FAA Registered Tail Number: 856JB, which stood for Aug. 1956, John and Bernice. Nacra F18 #856 Where's my matching Lear Jet? It was not delivered with my F18. (I could use it this weekend at the Statue of Liberty Race; it is the only way we will ever go fast enough to win!

Posts: 39 Dallas, TX | I will copy the e-mail Skip Elliot sent me when I asked for this info. But it relates to the MX sailplan.
In Rick's book there is a whole chapter on the original sail plan by Randy Smyth. I think he said he put the rake at 8" in front of the rear beam using the trapeze wire to measure. Then the rudder rake is set to provide desired weather helm.
As I said before I sailed it for years with original equipment using only the guidance in the owner's manual which is still available on the performance cat web site. With all due respect to Mr. Murphey, I would buy a different boat if it were necessary to do all he has done with his. I have been too lazy to reinforce my main beam or my rudders.
Hi Robert,
The way I set up The Prindle 19 mainsail with the mast. Start by setting the spreader back behind the mast 2" This is with a straight edge set from wire to wire and measuring the distance to the mast groove. The next is to set the tension on the wire so the mast has a perbend of 1" measure at the spreader with the mast set side way so the line from the top of the mast to the gooseneck will sag only to the ground and not to the mast. The line need to be tie to the groove at the top and bottom.
This is where I would start and from. If you are sailing light and need to flatting the sail start first by putting on more tension or the wire. so that you have more prebend
Now if you are sailing with more weight you may take out some prebend with looser wire tension. or you could take out some spreader down to 1.5" When it come to the spreader rake be carefully of putting in too much in This will make the mast bend too much in the middle and make the upper part fall off and the boat will not point up wind very well. This will start start to happen when you get past 3"
Keep a record of what you set the mast too and only change on think at a time. In this way you will know if the change was good or not and will be able to go back and try another setting.
Good sailing.

Posts: 699 SE Pa. or Chesapeak Bay | Hi Derrick,
The fixes/improvements I done haven't cost much in $$$$s but have just taken a little thought and some time. It gives me something to do after dinner in the evenings, also I was using the P19(MX) for doing point-to-point distance races here on the Chesapeake Bay .... no safety boats ... rough conditions sometime ... so when something important broke I fixed it and tried to strengthen/improve it. I had heard of previously of front crossbars failures on NACRA's and some Prindles ... when mine failed after I had up-graded to a MX rig and 25sqM spin I thought ... you've increased the loading from increasing the sailplan ... what did you do to increase the strenght of the platform itself to handle the increased loads???? Hence the reinforcing of the front crossbar and actually it was easy to do requiring the old broken crossbar for material, a Bosch Jigsaw, a 13lb sledgehammer, couple blocks of wood and a solid backstop (concrete curb).
And I did most of these, one improvement at a time ... over the years as I fixed what broke.
As for the rudder blades my first "elipitical" set split in approximently 40hrs of sailing ... the replacement set (of the replacement set) followed suit after the same amount of sailing. So I wasn't going to buy a third set and I couldn't locate a set of P18 Blades .... into the garage after dinner I went ... again not much $$$$, just some 3/8" dowel stock, a 3/8" drill bit, a little Epoxy&cloth, sandpaper and elbow greese(cold beer?).
I'll try and locate that thread where I reviewed how I strengthened the front crossbar.
Enjoy the process of rebuilding your P19 .... it makes sailing her all that much sweeter .....

Posts: 699 SE Pa. or Chesapeak Bay | Oh, I forgot or am I mixing threads ... the mast rake for my origonal Smythe "pinhead" sailplan was 12-14" in FRONT of the rear crossbar .... Smythes MX Sailplan; 12" behind the transom.
