Trip report, Dec. 2nd, 2000 by Peter Den Haan

The Great Escape, after a six hour boat ride, arrived at 7:00 AM at the Matterhorn in an unusually calm ocean. We had 24 Tech divers with various Dual Setups and slings, anxious to get in the water. Everyone was there, Bruce Bearfield from Dive-Rite, Michael Kane with the DIR group and of course myself with OMS. Since the top of the Pinnacle itself is no bigger than a couple of feet in diameter, it took Tim, the captain, about half an hour to get anchored.

Trip Report March 23/26, 2002

My second trip on the 116' Nautilus diving British Columbia confirmed it, to be the best diving I've done so far. Great friendly crew, excellent food, super comfortable accommodations and breathtaking scenery, makes the colder weather seem insignificant. Due to the colder waters, which definitely requires diving in a drysuit, and currents, British Columbia enjoys some of the most varied and richest marine life in the world.

  • It is only for diving deep
  • You have to watch your depth
  • More oxygen makes you feel better
