Hola!
Jag såg just bilden nedan som föreställer en Naish Fish 2011. Vad gör kanaler för beteendet hos en kitevågis?

Det måste få den att gå mer som på räls. Men allra viktigast så koncentras sprutet i lipcarven så det blir dubbelt så snygga bilder.

Det har funnits på en del vågbrädor sedan länge men jag har aldrig testat någon. Osäker på hur detta påverkar. Läser man på nätet ska det tydligen ge mer fart framåt och mer lift men också öka risken för tracking.

Channels: The channel surfboard bottom consists of flat planes that are designed in a concave configuration. They typically number from 4 to 8 channels and direct water flow down the length of the channel. Since the channels sit side by side to each other the water is not being compressed as it is in a full concave. These concave configurations of each channel propel water down the back underbelly of the surfboard and convert this into forward thrust. Longer and deeper channels give a more pronounced effect.

Quote:

Channels are more of an experimental bottom contour and, like the Vee shape, are employed towards the tail of the surfboard. Channels work best in clean surf and are designed to create extra speed.

Quote:

Channels that are shaped into the bottom of the surfboard allow the water to flow through to the fins and tail, the surfboard can tend to ride higher in the water than with those surfboards without channels.

Quote:

Channel bottom design can have up to 8 channels running along the bottom of a surfboard and there are a number of variations. Their basic purpose is similar to a concave bottom i.e. To direct the water from nose to tail giving increased lift and speed. If they are deep, long and have hard edges they may do this too well and make the surfboard prone to tracking.

Ungefär så förklarade Alex från Vikingsurfboards deras kanaler oxå. Skall testa deras bräda med kanaler senare idag om vinden lägger sig lite. Sen vet jag inte om jag vill ha en bräda som går med på räls. Jag gillar lite mer loose. Men skall bli kul att testa…
