Whale, submarine or school of fish!?!

Just today I was fishing out the back of 3 mile / staggies. In 22-27m of water.

We saw uneven water so went to check it out. And what looked like a school of large fish. It created a WAKE OF WAVES. We went parrallel to it and it wouldve been travelling close to 20 knots. We saw a 25-30cm fish jump out of the water (other times throughout the day too).

Im thinking maybe large tuna? Like 70-100cm. But can they create a wake of waves? We seriously thought it was a humpback whale. Nothing surfaced.

 a school of fish will create

 a school of fish will create many little wakes on the water (the distance between the individual waves on the wake will be the fishes approx length) and the waves will be only a few cm tall at most as each fish doesn't displace much water... 

A submarine will produce a single wake.  It would be about 1-2 feet tall and a huge gap between individual waves (length of vessel).  I'd expect in that depth of water a sub would be on the surface as that's not enough for him to be properly submerged

 Yep a sub won't submerge

 Yep a sub won't submerge unless there's 30 feet of water under the keel while down.
