Chartplotters and more
Kevin, IMHO it depends on what sort of sailing is done. Generally, I think chartplotters are more popular on bigger boats for a couple of reasons... the owner has the bucks to buy a large enough screen and color... and bigger boats may be more concerned with channels, nav aids and having the deepr water outlined.Your H260 like my C250 can gunkhole into skinny water and electronic vector charts are not as detailed as raster paper charts and don't show all the rocks, fouls and nooks and crannies that are helpful to many of the Great Lakes cruising grounds. I don't however want to revert to looking at co-ordinates and figuring where on the chart the position is... too much time effort and room for mistakes. For that reason, I'm not interested in a Charplotter, but I am interested in Chartplotting but using my raster charts.How is Chartplotting done then without a plotter? At least two possible ways, one is to use lap top or a pda and use moving map on a detailed raster chart. The process however probably eats up too much juice on an outboard equipped boat to leave it on for long periods, and a pda might not be large enough for easily seeing. I think a better plan is use a charting program with the raster charts, and make waypoints for all pertinent nav aids, as well as points of routes that keep the boat in safe water. Keep in mind however that having a lot of waypoints is useless without a tool to manage them... one has to be able to identify quickly a waypoint that can provide the reference needed for any given location. The answer to that is simple, mark the waypoints on the charting software and then print the charts from the software on 8.5x11 paper and laminate with the plastic protective covers and place in a thin binder.The result are detailed cockpit charts that are large enough to be easily read but small enough to be handled, that store easily under a cockpit cushion, and have all the pertinent data on them to allow a quicker and more accurate fix than struggling with finding and deciphering the lat & lon from the boarder of the chart. Because they are easily printed on the home computer printer, notations on them are easy to made without concern for the chart. Also, grease pencil works well on the outer jacket protecting the chart for making periodic progress marks or other notations for later log book entry or what have you.I've used this method of navigating northern Lake Huron, the North Channel and Georgian Bay for many years now and would not go back to navigating from the borders of full size paper charts. I've had a couple of charts get only slightly moistened at the edge. Planning of course if fundamental to it working as the multitude of waypoints are set prior to the cruise so that they are identified on the chart when its printed. Of course other points can be manually set and added to the gps. I in fact carry my lap top to make changes occassionally from original float plans and can do moving map display with it...but I've only turned it on one time in many years of cruising out of any need for moving map chartplotting and that was because we entered an strange harbor at Blind River, Ontario... and wanted to take anchorage out of the channel and outside the inner harbor because it was just after midnight when we arrived and it was absolutely pitch dark. The waypoints I had set, would have taken me into the inner harbor through the channel safely, but there was a good anchorage location off the channel which I didn't have a waypoint marked for and I had decided thats where I wanted to be until morning. Electronic vector charts would no doubt have provided the resource to navigate the channel to the inner harbor, but I'm not sure they would have provided the ability to get to the small shallow anchorage to avoid entering the marina at night and waking everyone within.Two nights ago, I finished printing the charts for the first of a two part cruise this summer on Lake Superior. This part is from Copper Harbor on the Keweenaw Peninsula of the Upper Peninsula of Michigan to and around Isle Royale National Park and return. There are 50 pages of charts with 150 waypoints, 10 routes plus two backpack routes as well as several divert havens, all well marked.The four charts needed to produce this were bought online from MarinePlanner.com at a cost of 4.50 each (they are the latest NOAA renditions and infact free upgrades for a year after the purchase of a chart) and I use the charting software called OziExplorer and I think it is currently $75. I've used the program six years now, after purchase all future upgrades are free and it has been upgraded a great deal in the last six years.Wow, I got windy... but I guess I felt like the chartplotter freight train has so much momentum and I needed to make a point, that there are reasonable aternatives to chartplotters that I think make a great deal of sense and are more in tune with smaller boat needs and budgets in terms of hardware, charts, energy consumption, and safety.Lastly,... the chartplotter may promote a discipline not to have backup paper charts or do precruise planning. Without backup paper charts and the plotter goes south... then the captain is SOL. If the weather turns nasty and its time to divert... without preplanning, judgements about divert locations are riskier than if preplanning caused a serious look at the locations and only notations made and waypoints set for those that seem reasonable. I doubt that using a handheld chartplotter during those times will yield as clear a picture as viewing a full scale NOAA chart allowed.Part of the issue may be the personal preference to visioning things. For many it may be that nothing works better than seeing a little symbol safely surrounded by blue. For others, knowing that two points and the line between them is relatively safe water because they've studied the charts and picked the points carefully is reasuring.
