What is continuous rocker?
Why are boards with single concave better for surfing on the rail?
Would most surfers notice the difference between a single concave and single to double?
What is the deal with big wave guns that have quad setup? I always thought a big center fin was key in larger surf.
Just a bunch of stuff I've wondered about. Any answers would be appreciated.
cheekobonavista , hi a lot of your questions are in this part of the site http://www.surfing-waves.com/surfboard.htm
there is an amazing amount of information on the site that can be accessed by using the search button, I invite you to try it!
I'll answer your questions.
50/50 rails are where the mid point of curve of the rail is in the centre of the rail between the deck and the bottom hence 50/50 not 60/40.
continuous rocker means that the board has a slight continuous curve along the full length of the board.
The next one is contextual and based on a surfers individual skills and preferences so it ain't necessarily so, only thought here is that some concave shapes either two or one enhance the rail function where they connect.
The better you surf the more you notice subtle differences, beginners notice gross difference and learn more as they go. Again there are different shaped concaves straight , inward curving, reverse concaves, narrowing concaves.
As for big wave guns as quads, it's to balance the three Cahones that the really big wave riders carry.
Some have three indentations in their deck to match the spacing
It's all about preferences in what they choose to ride obviously fine tuned as they worked their way up into that realm.
Big wave performance has gone from make the drop set you line and out run the wave to performance carving, the same board wouldn't make the cut
