Concave depth

Looks super fun to me. I've never surfed a board with those design combinations - a wider tail with a diamond to retain volume by going shorter, and to shorten the release point. I'd love to hear how it goes!

[Little]

Why don't you just buy one off the rack instead of fcking it up yourself?

[Davros]

Would a deep double concave work with 20" width with a longer board (say 6'2-4) with swallow/pulled in tail/tri fin and a medium rocker work,slight fished up but not super fish ?or would the same issues occur e.g. slow transitions etc...any opinions (have I described a Webber?)

Davros, A double can assist rail to rail as it creates a V in the middle of each concave. Again Im not sure of the purpose of wanting to go deep with the concave? Deeper concave = more chance of a board that doesn't work so well.

Most wider boards these days have either a Double in the combo, a V or a combination with both. This all assists in helping the board rail to rail, esp when going wider.

Mical, I've got a derivation of the WD shaped by Mark P.
mines 5'10" by 2" 1/2 by 20" 1/2.
Single to double with a slight vee out the back.
Really, really fun board to ride.

My biggest factor was dialing in the fins to suit.
At first I didn't have enough fin area...eventually got a set of foam core fins in that I reckon are at least M7's.

It's easy to overpower such a small platform.....depends how u surf though.

Natho, thought the deeper concave may provide a bit more life than subtle but with hold through turns for the slightly fished up thruster. Just thinking out loud.

Reworked the design last night, dropped it to around 191/8" and a bees dick under 5'8".

Going to run a slight single out to vee after the back fin.

Box of blanks ordered today, will post a pic of the template/ proper dims tonight.

A deeper concave would cause more trouble in bumpy and weak waves right? My understanding of concaves is that you need a bit of juice or speed to get them generating the lift

I have a small wave shape with a subtle single concave (1/6") to vee near the tail, and that goes unreal.

Couldnt you whack on some Futures Vector series for lift....ah f@ck I dont know. Thanks for the advice/info guys I'm off to ride some demos.

Heres a review of the Webber Almond by Nick Carroll, which uses a very deep single concave (I think their server is down at the moment though).

Greg Webber does a lot of deep doubles on small wave boards too, my guess is that a deep double with a bit of vee as Natho was talking about would be more user friendly.

[Cpt.Caveman]

Deep anything is not user friendly. Those deep twins of webbers are very specific boards, like his deep concave banana board of 12 or more years ago. Subtlety in surfboard design is where the true craft is. Of course webber is a true craftsman even an artist maybe. His more extreme designs, like the one you mentioned can often be seen as prototypes. Something to wake people up to new ideas. They are eventually dialed down to suit and make them more user friendly. Which doesn't mean boring, just functional.

So you think that his strong use of deep concaves is part of a push that will be dialed back soon?

He seems to use them on almost all of his current range, whether its a deep single or a deep double. The deep doubles seem to be used more with his huge raked twin fins (the mini fish, the twin-fin all-rounder, the twin-fin semi-gun), and the deep single is being used with his current HPS and the Almond Quad.

I have to admit, I haven't heard many people raving about any of them, except for the Mini Fish (but I think 3" of foam and the speed of a twin-fin could have something to do with that).

New template:

Will post rocker dims tomorrow, also considering NC's suggestion now ... with very little shaping experience:

v slight single concave under the wide point dropping back to subtle double concave through the fins and a v slight vee just behind the back fin.

Got a couple of blanks coming for this one, just in case.

Was originally thinking of a flat bottom

[mical]

In relation to concave depth, the following about right as a guide?

Slight = 1/16"
Moderate = 1/8"
Deep = 1/4"
Extreme = 3/8"
Maurice = 1"+

I have to admit, I haven't heard many people raving about any of them

I will rave all arvo about the 5'11" super concave Greg made me following that ASL board test.

The four fin setup worried me a bit, it just didn't allow for much turn modification and focused your turn too much on the rail (yes there is such a thing). Made the superconc a bit sticky.

So I got him to make me a thruster version with fcs plugs and stuck in a set of 3 template Phil Way hand foils. The board continues to amaze me with its outrageous turn of speed through and out the end of turns, its versatility and sturdiness in a range of conditions, and its sheer willingness to do things on the spur of the moment.

Thing is I don't think Webber has made any others like it.
