Is it necessary to remove the sail ?

I'd point out that there is a significant difference between what happens when the mast is upright, in its normal position and when it is laid out horizontally, with the weight of the sail causing it to sag and creating a great deal more abrasion against things inside the mast due to gravity...

Also, while a truck won't have 8-12' waves, it will have much higher speed vibrations that are probably far more damaging in terms of chafing... since the frequency of the chafe causing vibration is probably more important that the magnitude of the cause of the movement. 12' waves might have a period of say 10 seconds... the vibration of a truck might be thirty or forty hertz....

Dude....look at it this way. I spent several days in a row on several different trips in the Gulf beating against at least 5' and sometimes 8' and 12' waves with main rolled up. Did not damage my sail at all. Now do you believe a truck going down a smooth paved road is less violent then beating against the waves? I think not. Good night. I'm done with the lack of logic in this thread.
