My P19MX is in the backyard ... mast down ... but if my memory serves me, my mast (when set up) is approimently 12" BEHIND the transom as measured using the trap wire or halyard. you'll need to hold a straight edge along the shear line (upper edge of deck/hull) of the hull. Somewhere around here I have a Randy Smythe Tuning Guide, don't know where though. Basically Randy raked the mast until it would just miss hitting the mast base on the crossbar when the mast rotated. Note you will nead to really loosen the rig to get the step pin in and raise the mast.
My D-Wire Tension is in the same range ... Randy spec'd 2" of mast pre-bend. I replaced my stock D-Wires w/ DieForm wire to help w/ the increased loading
Hope this helps
HarryMurphey TheMightyHobie18(Mag), P19(MX) Thanks for the info. I had that same tuning guide but can't find mine either. The 18-2 guide (I have this one) won't work for rake on the 19 since sail plan and mast are different. If you run across your 19 guide i would love to grab a copy if possible. I was out this weekend in 12-15kts and was getting some weather helm, not too bad, but after 2hrs could feel it in my arms. Thanks again. | | | Re: Prindle owners - has anyone tried this
