That happened on our 6.0 as well with the spin up, not snuffed. The water made the bag sag and eventually tore from the pole. You may want to consider adding a mesh section to the bottom of your bag for the entire length. Or supporting the bag the entire length of the pole

It happened to me on the I20, end pole snuffer, during this year’s c100 going down the middle of the bay, downwind with the spin snuffed. I had just coated the spin with McLube prior to the race, and I think that caused the water to remain longer than it would have uncoated. We were already almost pitchin’ it every other wave then with all the water weight up front it was really ugly for about 5 minutes. I think it slowed us down considerable, which actually helped.

What is that pole made of? It looks like galvanized steel? You also may want to consider getting longer bridal foil wires. I think the NE 6.0 added 8" or went to 8" inch wires to raise the foil and the top of the pole. Rick Bliss suggested I do this with the 6.0.
