That's awesome!

It was so cool to see this.

[@branestormer1]

@6:13 put fins in the drawings to make them easier to read! nice work. mahalo!

[@jpwookie22]

I’ve felt too much single concave and like you’ve pointed out it was fast but tracked way too much. If double concave helps with lift and maneuverability why not run it up further on the board set inside a mellow single concave? Great and very informative video BTW. 🤙🏻

What would a deep single to deep double do, compared to a slight single to slight double concave?

[@wcc1212]

what is Billy riding in those 2 end clips?

[@TandCSurf]

I believe that may be our HRT model but a little difficult to tell

Hello brother, what do you think about the exchange of material, do you know a vegetable resin applied to EPS?

[@TandCSurf]

Thank you so much for your question! I'm Devin, the marketing and content specialist for T&C surf. We go out and film with Glenn in order to create these tutorials and other content but Glenn doesn't see these comments directly as he works at our surfboard factory in the shaping bay making world class boards! I didn't want you to feel let down if you didn't get an answer to your question but I have your question written dow and I'll ask Glenn the next time I see him 🤙🏼

[@marioferminio1]

@@TandCSurf Yes brother, ask him if he knows about this very important change for the sport. vegetable resin.

[@JohnCarrFitness]

Does anyone do triple concave anymore? I used to do them on my Florida boards back in the day

[@MichaelMiller-td5wm]

What's the difference in the handling of the board if you put the fins forward or more to the tail of the board? Better swing of the nose? I have been going to and brought up around auto racing since 1960. Understanding aerodynamics in auto racing helps me understand fluid dynamics when you explain surfboard design. It gives me ideas and makes me think about shaping. Like massaging the left front fender of a race car to pin the nose down going in to turn 1 at Talladega for more speed. One day I will shape a board. Thank you Glen for your explanation of fluid dynamics and how a surfboard works. At 66 years young, I Love to learn. Keep the informational videos coming. Mahalo and Aloha

[@TandCSurf]

Aloha Michael! If you have fins more forward, the board will pivot more and feel looser. If the fins are set further back, the board will be more drivey and feel more locked in a bit throughout your turns.

[@Pseudosurfer]

Thankful for this great informative video.

[@TandCSurf]

Our pleasure!

[@nickhlawka7073]

Hello. Im an amatuer backyard shaper but Ive been told Im pretty good. Im happy with that. You displayed the concave on the blue board. Does the concave end (flatten out) as it nears the rear thruster fin? Thanks

[@TandCSurf]

Aloha Nick! There is no right or wrong way to change the concave as it goes down the board, but what has worked for many of our boards is that the single concave transitions to a double concave towards the tail in order to allow the board to go more rail to rail in the tail of the board. Hope that helps!

[@nickhlawka7073]

Thank You@@TandCSurf

[@tokyomassa22]

Do these same principals apply to wide, swallow tail, twin keel fin fish designs?

[@topdeckdog]

yes
