Racing last Sunday when the winds dropped we changed to light lines with success.
Holding the spinnaker line was like fishing but Sea Ya keep moving while others struggled.

What is your opinion on using them on the number 1 genoa in the same wind 2 to 4kts?

if its going to weather in light the weight of the headie will close the leach one of the advantages of healing the boat in the light is it also helps to open the leach
