Glad your wife actually wants to get back on that horse! Just that attitude is awesome!
I took a dunk once, and what surprised me was how hard it was to right the yak with 3 poles, bait tank, etc... When I practiced, my yak was empty, and it flipped easy...but all the rods and crap added water drag to righting the boat!
My biggest fear is boats....I once shared about a lobster boat coming at me in the fog....
Best wishes in the future!
