why can't both sports be involved in the Olympics ?
The Finn class of sailing is beloved by ahem how do you say it, husky males in the sailing world that got their start as large "rail meat" lads, and they won't give it up for some skinny guys with a pole and surfboard. Same goes for the two person dinghy the 470, an over elaborate and over technical sailboat, the 49er, a fairly fast skiff for a monohull. Not to say the old classes aren't fun but they are incredibly obsolete.
There are only three decent sailing events in 2016,
1) laser -- fun and easy to relate to <--- should be the only monohull event
2) kiteboarding -- best sport ever
3) mixed two person multihull nacra 17, a very nimble and fast catamaran, lot of fun to sail, pretty advanced boat
Every other event should be cut for more cats and windsurfing.
