Seals(1.4, Black) - Seals Adventurer Spray Skirt

I turned 40, dislocated a knee, wife had a baby, and I got fat. I need a 1.7 for my boat, but i am wondering about the tunnel size on these.

Is this a universal cover? i can't find the dimensions of the cover in the description. i have a pelican trailblazer 100

Does the skirt have an exterior pocket?

I have a third coast arbor 100. the cockpit measures 22 inches by 47 inches with a circumference of 117 inches. what size would best fit?
