Depending on what you mean by "great depths". You could pressurize it, yes, but to a certain point. Breathing air under pressure has some consequences to it. You may either breathe it for too long or ascend too quick, and you'll trap air bubbles in your tissues, this is known as nitrogen poisoning. If you go too deep, say 50 meters, you will experience oxygen toxicity, usually leading to death, since you'd become paralyzed. Plus ascending may require decompression (otherwise you'll trap air in your tissues, this is considered rather painful).
Best is to have a solid body and have 1 bar pressure inside.No decompression and no problems. Unless the shell breaks ;)
Since it's polycarb, the whole boat is basically a window. I wasn't planning to submerge it for longer than the air tanks could sustain the atmosphere, but if you wanted to, you could scrub the air with Lithium Hydroxide or something.
