I've been seeing these little cutaways in a lot of boards lately, specifically minisimmons-esque boards. What is the function or does it just look cool? It's my understanding that a fish's pointed tail will allow for more hold in a steeper wave while taking advantage of a wider tail. These cut outs seem too small to have that affect. Anyone ride one or know the idea behind it?
I think it's intended to give your junk a place to dangle instead of being pressed against the deck. It really only works for tall dudes.
^ yes. It really lets your dangle flow free in the water, ultimately increasing the amount of planing your board will have during take off. You should see how deep the V is on my longboard.
In all seriousness its for exactly what you described. It allows boards with wide tails to hold in steeper waves. More rail line = more hold.
I'm just concerned with ball drag, it seems as though when the coefficient equals x to the 2nd power is multiplied by 2, the rate of loss of speed would be extremely noticable.
it also works to reduce the overall tail area in wide tailed boards. more performance, more hold, easier to get up on rail...a little less "skatey" & slidey.
Daniel Thomson (Tomo Surfboards) has been doing these for a while now. It's not a new concept but seems to really be becoming a fad since Tomo's been getting a lot of exposure recently. A good friend of mine should be receiving delivery of the V4 he ordered any day now. www.tomosurfboards.com
NJ and Erock, thank you for your responses, I was about to check out for a couple weeks again until I saw them. I've definitely felt the skatey/slidiness and don't mind that. On bigger waves I've actually felt like a skipping stone when I didn't have a rail dug in. I'm thinking this may help eliminate that feeling.
w/ all due respect, people were doing this type of split arc tail long before tomo...& really, tomo's tail shape is more of a double or split diamond than a split arc. it may seem like splitting hairs, but the subtleties are significant.
You guys are all stupid. What you want are parallel profile rails, 11ft of board, with an ego of about the same size. Any other discussions about board design are useless and should be directed towards this site.. www.sonfollowersministry.com/
i thought the split was supposed to help with the loss of flex on wider tail boards. i read that in the stuff rusty has been putting out about surfboard design
it does that, too, as part of the effects of reducing the overall area. whether it's clearly noticeable to the average surfer is probably debatable.
That's why I said it's not a new concept I will still maintain that Tomo's explosion in popularity has garnered attention from tons of shapers who are experimenting with their own versions of the design on their own shapes. That's why we're seeing more and more boards using it (anyone remember the chitstorm between Tomo and Biolos earlier this year?). They are all based in the original "old" concept, though--the basic idea holds.
