Cool information on the PBY-5A “Catalina” operations in the water. Come see the progress that we’ve made on our “Cat.”

How does an airplane land slowly in rough seas if it has no flaps for added lift and its wheels can't be lowered into the water to create drag?
So this question describes the daily occurrence of the PBY-5A Flying Catalina. This incredible machine had fabric wings, no flaps, drop down pontoons, and an aluminum boat hull for a fuselage.
Those are not heavy seas, and this is likely a takeoff, but you’d not be comfortable in a speedboat. In WWII it was invaluable to find the enemy, or rescue downed pilots; it’s wing a huge gas tank for 2,500 mile flights. That’s a looong way, and 20 hours routinely. The PBY-5A had retractable wheels, the “A” meaning amphibious.
Now as far as drag is concerned, at landing speeds for this craft (~90 knots), the fuselage is immediately huge friction (regardless that it is shaped like a hull). An airplane with wheels will not induce drag to safely land; they will provide an instant grab and flip.
