Rocker #'s
« on: February 29, 2012, 08:12:47 PM »
I am just starting to shape some SUPs and was wondering for surfing if somone could give me a ball park rocker # for nose, 12in nose, tail 12 in tail?
for a:
SImmons style 8ft

10 ft longboard laird pearson arrow style

short ripper style

Not trying to get any secrets just some ballpark # so I dont totally wast these blanks. I have been shaping for 6 years and am just starting to do SUPs for myself and wife but prob not for the shops bc everyone here buys cheap china stuff.

Cheers, David

I measure every SUP I can get my hands on to create my own database.

The average for an 8 footer is about 3.25 tail and 5.75 nose. Probably flatter for a Simmons. Maybe 3" tail and 5.5 nose.

Hi DW
I remember seeing one of your blog with a list of measurements on all your boards.  Can you link it here?  thanks

Well I think I had some luck its a little differnt for my first sup. I did a simmons inspired board since small funky boards are kind of my niche. I ended up with 4 7/8 nose I think and just under 3 for tail. Since my normal simms is 3 and 3/4 I think going lower than most is ok since I ride such low rockered boards. It ended up 7'11 x 30 x 4 1/4. Its has a hull entry to deep single to deep spiral vee. I also stepped the rails to be the same size as my HP long boards for big guys. I may have completley ruined a blank or it may end up ok so  we will see you can check a pic at my blog.

I went with low rocker since its based on a Mini simmons. I did a hull entry into single to spiral vee out the tail... Going to ride it soon hopefully we will see. I have only suped once on a 9 foot board and cought on quick. I have been surfing for a long time short and longboards so I enjoy the new challenge. I think I will make a 9'8 nose rider next. Thanks fo rthe help and sugestions.

The amount of rocker really depends on the type of waves being ridden, the style of board, the outline of the board and the surfing preferences of the rider. At King's Paddle Sports we run 6.25" in the nose and about 3.75 to 4" in the tail of our 9' Crossover models. The more rocker we use; the more the board hunts for wave geometry where the rocker fits. While extra rocker makes the board turn easily, it also scrubs off speed. When we build boards with extra rocker we build the speed back into the boards by placing fairly deep concaves in the bottom. We run a deep single into double vee concave. Keep in mind that here at King's "we build surfboards that you stand up paddle vs. stand up boards you might be able to surf." It is a mindset that we carry into the shaping room  ;)

Thanks Kings, I took the board out finally for a surf and it was fun. I thiink somone not used to riding low rockered boards would be having a hard time but I loved it. Got a fun little barrell on it and the tail held so I am stoked and cant wait to shape my next one.
