Common Questions
After you complete your purchase this is what will happen:
- We prepare your Build Details — the measurements and sail construction — and send them to you to confirm.
- Once confirmed, the information goes to our sail designer, who creates a detailed design plan.
- The design is sent to you for review and approval.
- Once approved, we proceed with making the sail.
Pricing for ERICSON 39 sails is calculated from the stored dimensions for this model, the selected sail type, the chosen build, and any relevant optional extras. Final quotations should still be checked against the actual rig, hardware, and fit of the boat before production.
Cross-cut construction is typically the more straightforward cruising option, with strong day-to-day durability and simpler panel layout. Radial-cut construction uses load-aligned paneling where available, which generally improves shape retention and performance.
Yes. Optional extras are tied to the selected sail family and sail type, so only relevant options are shown in the configurator. Hardware, reefs, UV treatments, bags, ropes, and reinforcement packages appear only where they apply.
Published specifications are the starting point, not the final production sign-off. If your spar, furler, hardware, or previous sail measurements differ, use the quotation flow so the specification can be reviewed before an order is confirmed.

We tore ours while in remote Indonesia so they had to work with our measurements and tight time line to get a new one sorted / shipped for us.
