Pryde X7 slalom boom, 190 to 240, excellent condition. I used this with 8.4 sail and has mostly sat in the garage for years but is actually a really nice boom. X7 booms were made before booms became thick and heavy. It is very light and stiff, with narrow diameter arms and although the tail is unfashionably skinny it is very wide in the middle, where the harness lines are. That width gives better leverage than many modern booms and the the low weight combines to make a very nice boom. The grip has been redone and the tail has the 3 pulley setup. Boom furniture not included.
Also a Severne 240 to 290 Formula boom. This is the one with the weird kink in the arms, designed to allow a massively wide mid section and very wide rear end. The arms are thin diameter with a v shape at the front for comfort. The width gives maximum leverage over big sails and allows them to be really full without touching the boom. Unused for a few years, in excellent condition having been re-gripped and the dodgy severne front end replaced with a Maui Sails front end. $700 ono.
