Radar plotter – approaching Prince Rupert from the west.<\/div>\n

<\/p>\n

The approach from the west to Prince Rupert, in northern British Columbia, is tricky. There is a twisty path through islands and reefs, with shallow water and few nav aids. Fish boats use this all the time, so when we departed the area heading north to Alaska, we crept through on a rising tide. Coming back this way was much easier as we had the track on our Furuno 2117 radar\/plotter to follow.<\/p>\n

Above is a computer screen shot using Nobeltec and their Passport vector charts. Prince Rupert is to the right, and the channel we want to use is at the top of the image.<\/p>\n

The twisty channel, now zoomed in, can be seen here. There are rocks and reefs all around the approach to this channel from the west.<\/p>\n

OK, here is the radar screen. The red trace from our departure a month prior can be seen descending from the top of the screen and heading off to the left, towards Ketchikan, Alaska. We are about to close our "loop".<\/p>\n

A detail photo: The computer is now on half-mile range, and we are beginning to wind our way through the old course back to Prince Rupert. The yellow target to our starboard is the wake of a small high-speed sportfishing boat that is passing us.<\/p>\n

When we were "pioneering" this track on our outbound voyage we were not nearly as relaxed as when we returned over the previously traced bottom.<\/p>\n

You can do almost the same thing, of course, with a chart plotter. We always keep a track, then save and label it at the end of each passage. But when we are working through a tight area, there are only so many things we can watch at one time. If charts are suspect, or lacking in detail, then the radar becomes our primary navigation tool. Having the old track on the radar screen then becomes a nice assist.<\/p>\n","protected":false},"excerpt":{"rendered":"
