The Sikorsky S-41 was an amphibious flying boat airliner produced in the United States in the early 1930s.

[1] Essentially a scaled-up monoplane version of the Sikorsky S-38 biplane flying boat,[1] Pan Am operated the type on routes in the Caribbean, South America, and between Boston and Halifax.

[1] The cabin was completely enclosed within the all-metal hull[1] and could seat 15 passengers.

[2][3] The United States Navy purchased three examples and designated them RS-1;[3][4] these were joined by two Pan Am aircraft pressed into Navy service and designated RS-5.
