The cut was a bit narrow, but not for a medium sized sailboat. We spent an overnight in the big lake, caught a few fish, had a great dinner and pressed on the following morning. The canal is not a navigational thing, it is nothing more than mere piloting. That said, I'm aware the transit price has gone up considerably since my transit in the mid "90's". Never been through the canal. My post was from a news item I found on a maritime website. The idea was the canyon it's in may cause poor reception of WAAS satellite correction data. Ideas are fine but modern science dictates one dismisses ideas and rejects theories that do not apply. In this case the idea that the Gatun Cut causes GPS satellite visibility issues is nonsense and the idea must be rejected and deleted from your knowledge base. The cut is far from a canyon with steep walls. There is plenty of sky for the GPS to see satellites. WAAS has nothing to do with it. Our primitive 1995 vintage Garmin 45 pseudo-tracker multiplexed GPS worked just fine when we went through the Gatun Cut in January of 1998. |
