VOLT VS. HERO
Battle of the giants
Draft forward or pull on both hands. Which wave sail fits to me best, my sailing style and my board? The latest (board-) developments make it necessary to offer more than one radical wave sail. To understand the differences, the fundamental aspects will be highlighted.
VOLT - single-fin
When going down the line a single-fin wave board wants to be “carved” mainly over your front foot and the rail. This requires high speed, full commitment and a very high skill level. Also you need to stand quite upright over the rail during the bottom turn. Therefore you need a sail with a slightly higher draft position to “force” you into an upright position. In addition the sail needs to go completely neutral during the turn. To achieve this the draft is positioned quite far forward. As a result the sail develops nearly no pull on the backhand and remains completely unaffected when sheeting in or out. On the other hand such sails are more sophisticated to sail, as the sailor does not get back any “feedback” (e.g. when over-sheeting). Also you simply have less to “hold on to”.
HERO - multi-fin
With the trend moving towards multi-fin wave boards the down the line surfing style has remarkably changed. In contrary to single-fin wave boards, multi-fin wave boards don’t get “carved” over the rail but instead get much more turned through the fins. The angular momentum for the bottom turn is now initiated through sheeting in your sail. To do this you need a sail that gives the rider a certain “feedback” triggering the turn. This means a sail with a draft position being further back and therefore pull on both hands. This pull on both hands has further advantages: As an advantage this pull on both hands means you have something to “hold on to” giving you extra balance/stability (which also counts for flat water sailing on single-fin boards). Also you can rig one size smaller as the further draft back profile produces more low-end power. Another advantage of this new sailing style is that the bottom turn is initiated at much lower speeds which makes it much easier especially for entry level wave sailors. On the other hand pros now can surf much closer to the impact zone. During the bottom turn you do not have to stand upright over the rail anymore but can remain in a natural slightly tucked position. Therefore compared to the VOLT our 4-batten wave sail HERO not only has a slightly further back but also lower draft position, which helps the high-end control.
