Will this fit my board?

Most likely, yes. Check the fin system on your board's centre box or side bites — US Box, Futures-style, or FCS I-style. Each product page lists exactly which system it fits. If you're not sure, our Fit & shipping guide will narrow it down in 30 seconds.

How long does it take to ship?

In-stock and made-on-demand orders ship in 7–14 business days. Preorders ship with the next batch — typically 4–8 weeks. Each product page shows the current stock state and batch progress. We email you when the order moves through each stage.

What if I don't like the feel?

Unused fins in original condition can be returned within 30 days for a full refund or exchange. Tried them in the water and they're not for you? Email us — we'll figure something out.

Are these proper fibreglass fins?

They are proper fibreglass fins with visible weave, clean colour, and hardware where the system needs it. The point is simple: quality fins should feel good, look good, and not be priced like jewellery.

Why are some fins priced lower than others?

Some fins are in stock, some are made on demand, and some colours/templates may open as preorders. The product page shows the current lead time before you buy. Read the full Feel Guide for context.

Twin fin a log

How a fin change transforms the board you already own.

A twin fin set on a longboard isn't a mistake. It's one of the most under-rated setups on alt-surf logs. Drop the centre fin, slot a pair of small twins or side-bites just ahead of the tail, and watch the board come alive.

The drift you feel in a fish — that loose, skating sensation — translates straight to a 9-foot single. The board still glides like a longboard. It just turns like a fish too. Everything you used to muscle through, you'll trim into.

This isn't a hack. Mid-century logs ran twin keels and side fins long before the centre-fin orthodoxy locked in. We're just bringing it back, in colour.

Why it works

The mechanics behind the feel

Looser through turns — twins drift, they don't pivot Faster off the bottom — less rake, more release Mid-length feel without buying a mid-length Fits any longboard with a 10.5" centre box Best on logs 8'0"–9'6"; not built for performance shortboards
