I37 was not where she'd been reported. After a half hour of searching and hearing reports of a seal offshore by various people I spotted a seal who I assumed was I37, foraging just offshore in the same area (behind Hauʻula BBQ) doing 2 minute dives.
Eventually I returned to 5AY's location but she had departed so I was no longer sure the seal I saw foraging offshore really was I37.
I returned to where I saw the swimming seal earlier and was pleasantly surprised to find two seals foraging. I didn't see any direct interaction between them but they did not stray too far from the area. They were still foraging in the area when I departed around 1700. I left Candy.
