2nd to None — Build Specifications

STOCK DIMENSIONS

Customer-facing catalog runs 4'9"–6'7" at 1" increments (23 sizes). Per-length width / thickness / volume / nose rocker / tail rocker are linearly interpolated from the 5 master Shape3D sizes (4'9" Small, 5'4" Small-mid, 5'10" Mid, 6'2" Mid-large, 6'7" Large) per Daniel Workflow §4. Built boards measure to within 1/16" of stock at every length. Custom orders outside the 5 masters scale within ~3" of the nearest master. The 6'7" Large is a linear extrapolation from the True Dimensions PDF cap of 6'6" — handled with Daniel during the Batch 1 round-trip.

OUTLINE

Wide point

center

Wide point (in)

Centered with slight forward pull (~34" from tail at 5'10" Mid master) per Album Insanity outline reference

Parallel section length

~24" through the wide-point zone at 5'10" Mid master

Nose width range

11.75"–12.25" at 12" from nose across the 4'9"–6'7" stock catalog

Tail width range

14.0"–15.0" at 12" from tail across the catalog (squash default; swallow tail width measured before Jack hand-cuts the notch)

ROCKER

Entry

low

Exit

medium

Flat (LOW) nose rocker is the everyday-quad signature — 4.03" at 5'10" Mid master = 5.76% of length per Lundquist's calibrated scale. Speed maintenance through fattier sections is the design intent; do not drift up to step-up territory. Tail rocker is medium (2.32" at 5'10" = 3.32%) for release-and-drive balance without sacrificing drive through the back third. Per Daniel Refinement Spec (Batch 1 May 2026): preserve LOW nose rocker across all 5 master sizes — the speed-maintenance hydrodynamics depend on it.

BOTTOM CONTOUR

Family: Single concave through the front 2/3 → vee-blended double through the back 1/3 (quad-friendly)

• ~3/16" single concave depth at deepest through the front two-thirds
• Vee component through last 1/3 — ~1/8" panel vee centered on the stringer
• Slight double concave (~1/16" depth) splitting the vee through the rear quad-fin cluster
• Blends to flat at the very tail (last ~3")

Single concave loads cleanly off the front foot through the wide point, then transitions into a vee-blended double through the back third — the vee spreads water outward toward the rear quad fins, which is what gives quads their sustained-drive feel through fattier wave faces. Album Insanity outline + this contour = the everyday-quad recipe per the Daniel Refinement Spec.

RAILS

Profile: 60/40 mid → hard-down through the last 12" of tail

• 60/40 rails through the midsection per House Style §3
• Hardened down through the last 12" of tail — quad drive priority; releases water cleanly off the back foot at speed
• Foil-forward foam distribution per House Style §4 — paddle support without violating the thin-tail signature
• Thin-tail signature preserved through the back third per House Style §2 — foam-from-tail trims meaningfully in the last 12"
• Apex sits at house-style consistent position — same relative placement on a 4'9" Small as a 6'7" Large per House Style §5

GLASS SCHEDULE

Deck

4oz S-cloth + 4oz warp

Bottom

4oz S-cloth

Finish

sanded

Standard everyday-quad spec — light enough for performance, durable enough for SoCal everyday use. Heavier deck schedules (4oz S-cloth + 6oz, or 4oz + 4oz + 2oz tail patch) available on request for surfers committing to overhead reef. Tier upgrades to resin-tint sanded ($900) or resin-tint gloss + polish ($1,100) per `custom-pricing.ts` `twin-fin-shortboard-stepup` size category.
