Yes, this area does seem a bit weak. And I heard that someone actually cracked the seams at the bottom outside edges...on a less than perfect water landing however...so in knowing that it might be a problem,I used some med glass cloth & finishing resin & added some strips on all 4 panels under the canopy,as well as the two bottom panels behind the canopy.
I won't be flying off water probably untill next spring...so it will be awhile before I can test it out!
Today,I finished putting the cowling on...ahhhh its starting to really look like a seawind
