Slalom Ski Sizing

Your choice of ski size must take into consideration many factors. Weight and Boat Speed are considered the most important factors. Recreational skiers will likely have a few more factors thrown into the equation than would a tournament skier. You may have to consider a larger ski if you ski behind an underpowered boat that has trouble getting you out of the water during a slalom deepwater start. Also depending on boat horse power, you may have to consider larger sizing if you plan on using double high wrap bindings, which can require more HP during deepwater starts. DIfferent brands of skis are sized differently as well. Some manufacturers sell 65", 67", 69" while others sell 66", 68", 70". As well, individual models of skis may require different sizing due to unusual shapes or characteristics. Tournament skiers that are about to change divisions might want to keep in mind any speed changes that go along with the division changes.
