Design Wind Load: 15 Lbs/Sq. Ft. 



Perpendicular Wind 



40 Ft. Boats: 8 Each x 1 9 Ft Beam x 5.5 Ft. Height x 15 Lbs. = 12540 

 Fingers: 9 Each x 4 Ft. Width x 1.5 Ft. Height X 15 Lbs. = 810 

 Multiply By 1. 15 For Row of 30 Ft Boats = 1. 15 x 13350 = 15352. 5 

 78 Ft Boat: 20 Ft Beam x 7.4 Ft. Height x 15 Lbs. = 2220.0
