The Flying Proa, so named after the Austronesian sailboat, is a CIR flying boat that shares parts commonalities with the Sidehill Gouger. The intent of this arrangement was intially to avoid the need for a second float and minimize drag. However, as can be seen, practical experience led to the addition of a starboard wingtip float. Developed roughly in conjunction with the Sidehill Gouger, the Flying Proa is one of the relatively few seaplanes used outside of the USS.

As it's unusually conventional paintjob suggests, it's mainly tasked as a waterbomber, but it's also used as a cargo aircraft and in sea rescue operations. For cargo purposes, it's specially valuable as as means of communications between the coast and the lakeside and riverside communities in the interior of the peninsula.
