A couple of tricks I've done to my P19MX:
I have Trap Loops made of Wire Rope, not "Dogbones" ... as some pointed out metal dogbones can cause injuries when they fly around. Very cheap to make.
For stoppers I use the small plastic pieces but I use TWO per trap (back to back) as I've had several break in half while I'm hanging on the trap.
How is your bungie run??? From the line W/ the loop/dogbone down through the hull ... Straight over to the other hull ... through that hull to the line???? You will find you will be fighting the pull of the bungie as you try to trap out at the rear crossbar ... when your crew traps out and tries to get that far aft they will not be able to comfortably do it at all (thats required when you are flying a Chute!!!) So here is the trick install a double Harken Micro or Air block at each corner of the underside if the tramp at the rear crossbar. Run the bungie through the hull back diagonally to the opposite corner ... through the block ... across to the other block ...then diagonally to the other hulland through it as usual. This almost triples the length of the bungie cord and the stretch availible so you can move around fore & aft to a much greater degree.
Now you can enjoy a screaming reach ... The P19 makes pretty rainbows with the bow spray from the leeward hull!!!
Do you have the "origonal" short stock rudder blades ??? If so upgrade to the new rudder blades that are much longer w/ eliptical tips ... or find a set of used P18 blades w/ square tips ... they are also longer. On a screaming reach the bow drives down slightly, the stern rises ... the rudders start running through the disturbed water/wake and loose attachment ... no stearing/helm ... she will go straight as a rocket but you can not turn ... You ned to pop the main slightly to release the pressure and regain stearing.
Enjoy your P19 it is an awesome boat!!!!!
