Reinforced cup for Optimist mast root. This version has been improved on several points to increase its durability:
- The base and the rounded part of the cup are thicker, going from 1.5 mm to 2 mm.
- The weld between the cup and the threaded part has been reinforced.
Note: This reinforced cup weighs 30g more than the existing version.
Good news: the new cup is compatible with all base plates already fitted in boats, allowing for a simple upgrade.
