Hi Pepin,
You are correct as I kind of mixed your two sentences together in your first post. But I'm not sure if a new or re-cut jib would be reguired for the installation of a roller furler.
Your advice about when having your jib secured w/ a tie strap when furled is exactly how I leave my TheMightyHobie18 over-night at a regatta ... but I do remove my jib if I'm not sailing the next day. Note I've lost count of how many times I've had to secure someone elses jib flapping in the breeze ... of course you have to remember to UNTIE the strap before leaving the beach (Don't ask me how I know ....)
I could find nothing in the background of the H16 to indicate where the picture was taken ... the custom sails and all-aluminum mast (and your european location) lead me to believe that the picture was from Europe. But my comments about the comptip/spinacker are sound I believe.
I could tell from the cars in the background that the H14's were located in the USA (also the lack of a front license plate indicates to me that one of the cars maybe from Pennsylvania, there are only 2-3 states that do not require both a front and back license plates) Do we know "where" those two H14's are from??? Virginia Beach area??? ... Dan Berger??? .... Dan had organized a nice little fleet of H14's w/ Hooters/Screechers racing in Va Beach several years ago.
I don't think the installation of "Adjustable Spreaders" would be to difficult on a N5.2. They are availible through Annapolis Performance Sailing ie: APS at
