Scuba/diving kayaks?

Been a while since I’ve been back on the board. Was scrolling through Craigslist the other night and saw quite a few cheaper diving/scuba kayaks.

My question for the group is are they good to fish off of? If so, how do they paddle? The storage capabilities are really what’s so intriguing. And apparently they’re very sturdy and buoyant. I’ve never dove and know nothing about these kayaks so any info would help here. Thanks!

Some big fishes caught of paddleboards/surfboards even. Natives used boats made of twigs/reeds? Typically longer and sleeker is faster and wider and fatter more stable. Wear a PFD/radio and watch out for George..
