Sail cut short

Trip dates: 
Saturday, January 11, 2020
Trip length: 
1 day
Type of watercraft: 
Sail

While raising the main (genny out for repairs) in the channel by the base at Little Creek the patrol boat cut in front of me to shoo me away. Wind was honking and I had to stop raising the main before it was all the way up, Beared away to avoid collision with the patrol boat and the loose halyard gets caught in the mainsheet block at the base of the mast. Uggg! Dropped the traveller and headed down the channel and noticed 2 shackles on the luff slides for the main broke. End of sail. Thank goodness for Sailrite! Ordered exact replacements.
