Lift

Can somebody explain why I want lift in my surfboard?  What does it do?  Should it be in the tail?  The nose?  Lot's of people I know talk about it and none of them can give me a solid explanation.  Thanks for any input.  peace.

a 19" wide shortboard  without the addition of lift

on the bottom through concave and without the fins which are cant’ed out  makes for a pretty poor board

even for Kelly Slater.

 

Take that shortboard make it wider and more thicker/buoyant then issues of lift are not so stark.

Take that original 19" inch board and make it 18" wide  and you"ll have to increase lift to compensate

 

Toe-in on fins creates lift, but is not a primary variable for increasing your lift as it effects the turning radius explicitly.

 

Comprende’

You make a little bit of sense but fall short of a cohesive answer.  Maybe the oven was on or something.  If toe-in is part of what creates lift but not the "primary variable" maybe you could expand on your answer and enlighten this ignorant noob.  Also "more thicker" is redundant.  redundant.  A google searchbox is pretty one-dimensional...  sort of the same as your answer.  Thanks anyways guy.  peace.

You might want to work harder to decipher the answer. There’s a lot of stuff there, and he could have just answered your “why would I want lift?” question, by saying “Because it will keep you from sinking.” It could be that you’re asking something like “How do I get a board to go fast?” The problem is that there are many answers that all depend on the board, rider, conditions, mindset, etc.

Bad manners is redundant. redundant. You post a very vague question, get a response, and attack? Look it up yourself if that's how you show gratitude for help.

 

hmm, berating my answer and playing the grammar card…

over and out here!

try the archives to learn surfboard theory

Lift is good when going slow.

 

Do you mean the lift created by floatation, or lift created by planing and speed over the water, or the design term used referring to rocker?

 

Typical english language eh...... one word meaning many things, and many words meaning one thing!!!

Toe-in itself doesn’t create lift, it creates drag. Cant helps create lift. A narower board goes rail to rail easier, but lest stability, less floatation (generally), and less planing/lift. Concaves tend to channel water. It depends on the shape, and hundreds of other details, where you want to channel that water, or if you want to channel it at all. It’s not something that someone can say always do this here or do that there. There are far to many variables and varying wave speeds and conditions.

 

Crafty has a good short version of an explanation.

 

 

Here’s as solid an explaination I can muster…

You want lift to compensate for a lack of speed that helps you plane on the surface. So creating lift through design (concaves, ect.) is most critical in performance boards meant for small or weak surf, and progressively less important as the wave energy increases, when the wave provides more than enough speed to keep you planing. You can compensate for a lack of lift through increased volume (flotation), but that only gets you so far in terms of performance. So as somebody already said here, lift keeps you from bogging, keeps you planing, and so keeps your speed up.

With that in mind, where do you want to create lift? The short answer is, under your center of gravity to help compensate for the bogging effect of your weight. So on most boards, the deepest part of the concave(s) is/are between your feet. On a noserider, it might be under the nose, because that’s where you’ll be perched. Fin cant creates lift in a similar way as an airplane wing, and since they’re located very close to your back foot, they work well with modern performance oriented, back-footed surfing.

This is all oversimplified stuff, and there’s much, much more to it than I can begin to grasp. Do check the archives. There was a great thread or two not too long ago on concaves that really got some good discussions going.

The 'why' is for ease of motion, what surfers like to call 'speed'.

[quote="$1"]

What does it do?  [/quote]

The 'what' is it reduces the amount of water in contact with the board, reducing resistance to motion, increasing speed.

Should it be in the tail?  [/quote]

Generally yes but sometimes no. Its either good or bad depending on what you want out of it. Many modern boards dont have tail lift naturally. I wouldnt want a lot of tail lift at Pipe.

The nose?  [/quote]

YES. Rocker and width is your main source.

Solid?

 The "lift " is what I use , when I don't feel like walking up 6 flights of stairs...........................sometimes

Thank you nj surfer and crafty for your time and helping me start to understand this concept.  I knew going into this that it was more than a one sentence explanation.  Otis I think you really take yourself too seriously.  If your butt hurts try preparation H.  I'm  all for serious discussion but it is hard to trust an answer when the writer doesn't have a clear grasp of how to write, just trying to have a little fun too.  See you in the water...  or will I?

p.(m).s.  I did check the arcives and I will check them again thanks for all your comments.  Laugh, live, learn and seriously lighten up.  peace.

You don’t not need lift for surfing a surfboard.  Hope that helps.

Good waves always gives my surfing a lift!!!

Hope you get few deejer3000.
