Spider sails are carefully made to meet the requirements of the Soling One meter Class rule 6.0.
Each sail is cut to shape using our custom made aluminum templates that have been precisely produced to a tolerance of plus / minus .002, following the measurements shown on the Official Sail Control Drawing Revised Feb.14 / 2005.
After cutting, each sail is individually measured to ensure compliance with the rules. A production number is applied and the sail is signed to show compliance.
The production numbers are recorded on the Certificate of Guarantee which is signed and dated, to provide our guarantee of compliance. The Certificate of Guarantee is included with the sails when shipped.
