Lennard and I were quite keen and ended up in the water first, and we spent some minutes with the seals on our own.
The seals would imitate every move we made. I took great delight in doing loop-the-loops and all 20 odd of the seals would do the same after watching me. The same went for barrel rolls.
An excellent experience.
Lennard had trouble with weight, and concentrating on his diving with the excitement of the seals. We cut the dive short and headed back after realising the problem was weight.
