Ok. Let me elaborate on my use of the air compressor. I was free flowing 5lbs through a 3/8 hose for 10 seconds or so. Not much volume. Yes, if you have a perfect seal and a non functioning vent, you can blow the deck. Shop Vacs are a fairly low pressure device but they DO inflate much faster with that 3inch hose. A ShopVac can fill your hulls way quicker than an air compressor.
