I owned a 26' Glacier bay and a 30' Hydrocat (which are out of business) (also owned many mono hulls, but love the cats)
The GB handled rough water
better than any boat of similar size that I have been on. Yes it is slow, but that is the design. With twin 4 stroke
150's, and loaded, mid to high 20's is it.
I was selling my GB, and had a prospective buyer on board. For the sea trial, we were coming out of the inlet and was up on a HIGH wake from a 60' battlewagon. I got to the edge and looked at a 4' drop and said "OH $HIT!" waiting for the big bang as I went over.
Nothing! Just like I had gone over a small wake you cross every day. The man with me smiled and said turn around, I'm sold.
I would like a 30' GB, a model that they no longer make.
