It's hard to judge from that selfie perspective, but I think the guy that NFFC posted has him beat for top end.

hhhh, nailed it.

Might have a couple "stress" cracks in that 'glass though.

Seen that a few times. How fast do you think? 60mph?

those unlimted class hydroplanes easily exceed 100mph. My guess is around 120mph because that's the speed where lift generated seems to get serious.
