A1 – Light Air Reacher
The A1 has a reasonably flat luff and narrow shoulders to sail tight angles and improve light air performance.
It is made of light material to reduce the weight and let the sail fly properly in the light breeze.
A1.5 – Light Air Runner
The A1.5 combines the characteristics of the A1 and A2. It is slightly flatter and with narrower shoulders than the A2 to improve the light air performance, but it has a longer luff and mid-girth than the A1 to allow the sail to project for sailing deep angles.
A2 -Medium Air Runner
The A2 is a full, powerful sail designed for running in moderate breeze. It has the longest luff and largest girths of all of our spinnakers, allowing the sail to project to windward when sailing deep angles.
It is usually made of a light or medium cloth
A3 -Medium Air Reacher
The A3 is the choice for reaching in medium air. It is a full size sail made of medium weight material. The sail is designed flatter than the A2 to improve reaching but with a longer luff than the A1 to sail broader angles in moderate breeze.
A4 -Heavy Air Runner
The A4 is a full, powerful sail designed for running in heavy breeze. It is made of a heavier material and a slightly shorter luff length than the A2 to give that extra bit of stability needed in heavy breeze.
A5 -Heavy Air Reacher
The A5 is a heavy weather reaching sail, with a straighter luff, flatter entry and shape to help when there is plenty of power in your sails. It can be either a masthead or a fractional kite, depending on your needs.
