When you do take him for that ride you might want to consider acclimating him back to the ocean for several obv reasons one mainly being water temp and PH. If you just drop him over board the shock could kill him. Also I remove all hitch hiking urchins I find just recently a solid black one appeared and I quickly removed him. When you can't ID the species you are playing roulette.
I already thought about that. I figured while I'm doing my first dive he can chill in the livewell on the boat. While I'm diving my buddy can slowly add the outside seawater to the livewell. On my second dive I'll take him down with me.
