The Allen Brothers halyard lock is standard on Europe masts and we suggest it also for the Splash mast. This lock is easier to use than the standard Splash halyard lock. Just set the halyard on the first knot and when you tighten the halyard the following knots slot in to the lock without the sailor having to check up above.
We suggest a distance of approx. 20mm between the knots for an accurate halyard trim and optimal performance in the Splash class.
