True. But children of Poseidon/Hades have another advantage. Land. So even in a battle away from the ocean Percy could still obtain the upperhand by making the ground a hostile enviornment. Jason can't just fight in the air. Cause land too is everywhere. Nico/ Hazel have also shown they can summon the dead/precious metals from anywhere. Also take this into account. Hazel could easily disarm Jason. Or anyone for that matter...
