Over the past few years wavesailing boards have progressed, and grown more and more fin boxes. First there were twins, then quads, now thrusters and trailers (both three fin boards).
Many think that the quad is now the go to waveboard, used by the majority of wavesailors and, whilst many do go for four fins, it’s not for everyone in all conditions.
For example Philip Koster (and most of the Gran Canarians) still use twin fins in the Canaries and similar conditions. Whilst they might switch to quads for down-the-line conditions, it just goes to show you don’t necessarily need a down-the-line board unless you’re actually in those conditions. You’re far better looking at a board that actually works in the conditions you will be sailing in and for what you want to do, that just going for the most radical wave board on the market.
