Hey Wingtime,You will know this; I remember reading there is like 40,000 # of paint on a 747, you think this AS is close!
I've had two adults up in mine and you cant really tell they are up there. Mine is on top of the tee top. No Helm, just a spotter tower. I suggest you make it a folding tower to get under low bridges and that wayward telephone or CATV line that are notriously not 13' 6" off the ground when you trailer her. Everybody loves to ride up there when cruising or spotting Cobia. I will admit, I'm not sure how it would be in 5 foot rolling sea across her beam but you pick you days!
... we have had some pretty windy days here in SW Florida this week.
