FAQ

Do you need my exact measurements?

Yes — the dimensions above are typical values. Masts are often modified over decades of ownership, so we always confirm luff, foot and leech measurements with you before cutting. We send a simple measurement guide.

How long does a custom sail take?

Typical production time is 2–3 weeks, plus shipping. Every sail is cut and built to order in our partner loft.

Can I get my sail number or logo on it?

Yes — sail numbers, class insignia and your logo can be added to any sail.
