Heinz,
Crew member - same as me. In the tuning guide, they recommend shroud and forestay lengths to conservatively rake your mast backwards. When you do this, the tendency to pitchpole is greatly reduced. When you do this, you'll probably need to rake your rudders forward a little due to the increased weather helm you'll now experience from the mast being raked back. Other "musts" - carpet or other non-slip on your sidebars and foot stays/holder on your side bar and one on the aft-most hull (for your aft foot on a screamning high wind reach)
Re solo righting, I wrote a paragraph or two in the H16 forum about how I use a right bag, I'll go try and locate if for you if I can.
Other ideas. I have my jib sheet as two separate lines with a plastic snap on the free end that I snap to my trapeze shock cord (so it's always available to you when on the trapeze.
You'll probably want to rig your jib traveller so that it can be adjusted (explained in most all H16 guides, hardware available from Rick White's store and others). The line from the jib traveller I have shock corded to the aft most foot holder so it also is within easy reach when trapped out.
Also- if you're sailing alone, you'll be getting tired sheeting in/out your main so I purchased a nice Harken 8:1 low profile block - easier on the arms.
Cheers
Ron
