Half-Moon

A moon-tail twin built for the surf you actually get.

TWIN FINTWINCHEST-HIGH TO SHOULDER-HIGH SHAPED SURFFROM $750

The Half-Moon is built around a moon tail — the crescent shape that sits between a swallow and a round, with the wings opened up so the tail breaks loose at the top of a turn the way a fish does but holds through the bottom the way a round-pin would. The bottom runs single concave through the belly into a double concave behind the fins: speed through the middle, drive on the exit. Medium rocker keeps the board paddling cleanly and tracking on the open face. 60/40 down rails through the midsection feel forgiving at twin-fin speeds; the rail hardens through the last twelve inches to release water cleanly off the moon-tail wings.

WHAT IT WANTS

Clean waist-to-head surf with shape — beach break, point, or reef with some push. Twin fins want a face to drive off; dead-flat mush won't bring the shape alive. Punches above its weight at Lowers, Salt Creek, and the smaller-day Mentawais.

SKILL LEVEL

Intermediates and advanced surfers wanting twinzer hold with a moon-tail outline.

WHAT IT'S NOT

Not a flat-day groveler — for knee-high mush, a wider and flatter shape will paddle and plane better. Not a hollow-reef board either; when the surf gets big and heavy, a dedicated shortboard or step-up will give you more control.

WHERE IT WORKS

The everyday twin in our scope: built for the surf SoCal hands you most months of the year, not the once-a-month dream session. Think a soft south at Lowers, an organized morning at San Onofre point, T-Street with shape, Salt Creek on a chest-high day. The Half-Moon paddles into peelers without grovel-board volume and draws clean lines through the open face. Push the tail and it releases; commit through a turn and the moon wings catch and hold. Travel use: mainland Mexico point surf (Saladita, La Ticla), Scorpion Bay, Baja peelers, Indo on a softer day.

WHO IT'S FOR

Intermediates comfortable on a twin who want a forgiving daily driver, and advanced surfers who want a twin that holds through a deeper bottom turn than a swallow-tail fish allows. Not a beginner board — without a center fin you're committing to twin-fin feel. Not a grovel board — when the surf goes flat, a wider, flatter retro fish will plane and paddle better. Not a step-up — when the surf is overhead and up, reach for a different shape.

THE DESIGN

A twin fin trades the all-conditions versatility of a thruster for speed off the bottom and looseness through turns. Wider plan-shapes than a shortboard at the same length pull the wide point forward, with a fast back third built around the fin cluster.

THE RAILS

Forgiving rail-to-rail feel with hard tail rails for clean release at speed. Mid-rails stay soft for trim hold; rail thickness flexes by length and rider intent.

Custom builds are tuned to your dims and surfing style. Talk to Blake about specifics.

FIN SETUP

Twinzer setup. Futures boxes. Two larger main twin fins plus two small canard fins ahead of the mains — four fins total, twinzer geometry. The canards add hold and drive without the full footprint of a thruster. Twin-only setup also available if you want the simpler config.

Need help picking templates? Read the fin guide, then start a conversation — Blake's happy to talk it through before you lock the build.

Recommended Fins

Twin fins live mid-rake to rake-leaning. Drive and looseness both want side fins to hold a long arc rather than pivot tight. Lean rake for fattier point break and longer carves; sit nearer mid-rake for punchier beach break. V4 Part B: 2 picks per brand spanning mid-rake (modern keel for punchier surf) and rake-leaning (classic keel for fattier walls).

RAKE SPECTRUM

Where each recommended fin sits between drawn-out rake (heavier arcs, more hold) and tight pivot (vertical release, modern shortboard turning). Mid-rake (neutral) is the balanced default.

On a twin fin, the spectrum reads: rake = sustained drive and trim speed in fattier waves; mid-rake = the everyday pick that still releases off the top. Pivot-leaning twins exist but are rare.

WHAT TO PICK

Twin fins live mid-rake to rake-leaning. Drive and looseness both want the side fins to hold a long arc rather than pivot tight. Lean rake for fattier, drawn-out point break and longer carves; sit nearer mid-rake when you want a touch more release on punchy beach break.

FREQUENTLY ASKED QUESTIONS

What size Half-Moon should I order for my weight and the surf I ride?

Pick the length and width that puts you in the 26–35L band for your weight and skill. The featured stock-dim band on the page is tuned to the everyday-twin window — that's where the moon tail does its best work. Sizes outside the band (smaller groms, heavier riders) are available via the All Sizes toggle. Between sizes? Size up in volume for softer surf, down for overhead with push.

Why a moon tail instead of a swallow or a round-pin?

A swallow releases water early — looser, more pivot, great for small-wave fish feel. A round-pin holds tighter through a deep bottom turn but feels less alive in mid-range surf. The moon tail sits between them on purpose: the wings open up enough to break loose at the top of a turn but catch enough to hold through the bottom. It's the middle-ground twin.

Can I order the Half-Moon as a thruster, quad, or twin-plus-trailer?

No. The Half-Moon is twin-only. The moon tail and bottom contour are tuned around two fins specifically — the way the wings release water and the way the double concave drives behind the fins both depend on the twin setup. A thruster, quad, or 2+1 conversion would fight the shape. If you want a quad, look at the shortboard models; if you want a twin+trailer, look at other Lundquist twins.

What kind of waves does the Half-Moon want?

Chest-to-shoulder shaped surf — the daily SoCal window. Soft south at Lowers, organized morning at San Onofre point, T-Street with shape, Salt Creek chest-high. Travel use: mainland Mexico point surf (Saladita, La Ticla), Scorpion Bay, Baja peelers, Indo on a softer day. Not a knee-high mush board, not a step-up for overhead-and-up — those days reach for a different shape.

Is the Half-Moon a beginner board?

Not really. Without a center fin you're committing to twin-fin feel — the board breaks loose differently than a thruster, and the moon tail rewards a rider who knows how to load the back foot. Intermediates comfortable on a twin will get along with it; advanced surfers who want a twin that holds through a deeper bottom turn than a swallow allows will too. Beginners are better on a wider, flatter board with a thruster or 2+1 setup.

How long does a custom Half-Moon take to build?

Turnaround depends on the finish:

  • Clear resin sanded — 4–6 weeks
  • Tint gloss + polish — 6–8 weeks
  • Resin tint sanded — 8–10 weeks

Timeline reflects the current queue and is confirmed at order. A 25% deposit locks the build slot.

How does the Half-Moon compare to a CI Two Happy Twin or an Album Twinsman?

Same modern-twin family — single-into-double concave bottom, medium rocker, twin-only intent. The divergence is the tail: the Two Happy runs a squash, the Twinsman varies, and the Half-Moon commits to the moon shape specifically. The moon gives a slightly wider working volume range than a pin tail and slightly more hold than a swallow. Pick on tail preference more than on hydrodynamic feel.

Can I try a Half-Moon before ordering one?

Sometimes. We keep a small number of display boards in the shop in Carlsbad so you can hold one, check the moon-tail outline, see the finish. Message us to confirm what's currently available — stock rotates as boards sell. There are no in-stock Half-Moon boards right now (April 2026) but we'll flag when one lands.
