Non veni pacem mittere, sed gladium.
Which seaplane do you favor (make/model)? I don' know how you can beat a Beaver, but there are other options.
Still researching. I have a lot to learn, but indeed, the Beavers have a lot to recommend them.
CW, It will be interesting to see which you prefer & why!
The "which seaplane / floatplane" needs, the how much, how far and how many questions. That P&W radial engine on a Beaver is one of the best sounding engines ever. Notice that I did not ask the "how fast" as none are speedsters.
