Guys 'n Girl lets continue weight discussion here. Otherwise the arguments will be spread over the forumboard and very difficult to look up later when the vote is put on.
As the discussion seems to partially to focus on the gennaker gear I would like to present the following link as background information.
http://www.geocities.com/f16hpclass/Tech_weight_and_cost_spi_setup.htmlAlso an update :
I just weight new (on-off) ratchet blocks+shackles of a lesser known and cheaper brand and they came out at 80 grams each. This in comparison to the 156 gram each of the ronstan blocks I used on my P18. A total gain of about 150 grams over two blocks. With the smaller blocks for the halyards the gain will be 200 grams. Ergo the option listed as inexpensive homebuild option with trampoline bag comes out at 4,7 kg's for the whole package.
I have my own comments on minimum weight but I will post them after the others have had their say, just like as was done in the mast height thread.
