I'm interested in some more comments around the north's 3Di products, specifically around shape retention, durability and expect life of the sail (especially shape retention over the life of the sail).
Looking at a new main for a 37 ft cruiser / club racer.
To replace a like for like cross cut dacron from a local loft (whom I've used before) is circa $3,500
A tri-radial laminate from the same local loft is circa $5k
A 3Di Nordac circa $8k, or a 3Di race circa $13k - made in Sri Lanka
To compare with the local loft cross cut dacron, a Norths cross cut dacron is $6k
Based on the cost difference of the cross cut dacron, it would appear the label in the front corner of the sail is worth a lot. However I understand the 3Di products are good sails. I'm trying to quantify how good, as there is a substantial price difference.
For that price difference, I almost be expecting a sail that can pour cold drinks and put the kids to bed... but maybe my expectations are unrealistic.
