Didn’t see a “What if” category, so if this can be moved, please do.
Supermarine Sprayfire Mk.I
Long Range U-boat Patrol Squadron 777, Kirkwall, Scotland. 1943
I know they had the dual float Spit, but I have always thought the single centerline float to, at least appear, more elegant. I had the leftover waterline float parts for a Fujimi F1M2 Pete, and have a penchant for floatplanes and a wacky imagination. I did a quick Google search, and the only image I see in this configuration is a weak Photoshop try by a “WarThunder” game fan. I also did a quick search on weight. Empty weights are similar. You would have to shave some weight off of the Spit, I believe, to make this possible. Less Guns, More wood components, etc. The Landing gear and associated mechanisms versus The float would be a wash, weight wise, probably?? Enjoy!!
