Default Newbie plotter question

If I'm storing waypoints along a route would it be more accurate if I slow down or does it not matter? The manual makes no mention of it.

Thanks

If you are worried about the accuracy of your route that you are storing as you navigate, just change the settings on your chartplotter to save waypoints more often.

When you go back to name the route and do some housekeeping of your plotter's memory, just delete some of the unneeded waypoints from the route (i.e. - those waypoints that are very close together due to a slow vessel speed).

I've done this on my Garmin 2010C many times, especially when navigating channels where depth and precise placement of the boat is deisred.

I would guess you're taking the Plot-Trail/Track displayed then making the plotter create the route for you. You probably have user selectable Plot-Trail/Track update options in time or distance. If set to distance then the shortest yields the most points and boat speed isn't that important. When using a short period Plot-Trail/Track update (1 sec) is best resolution I can plot, which is great for narrow channels and tight turns. However all those points fill-up the memory quick (1sec interval = 12 min, 1nm interval - 75 nm) and once the memory is maxed out the earliest points are erased and memory used for the newest points. For the most accurate Route & Trail figure you travel time thru an inlet/harbor, set your update by time allowing extra for delays, convert the Trail/Track to a Route and save it for later use.

Thanks guys.
I'll read up on the trail/track feature.My thinking is to set up routes to the usual places
(inlet,etc), verify during daylight and save for night/fog. I go splash Saturday so I'll get to play soon.

Richie -

I bought a Garmin GPSMaps 2010C and when I first got my boat in the water, I did the same thing you are doing - set up all kinds of routes.

Those routes were quickly deleted as I becam familiar with the waters. You will also become familiar with the waters you navigate AND your chartplotter will display your boat's progress as you travel. Even if you do delete your routes, at least you have become more familiar with your electronics.

The only routes I have saved are for one local pass that is kinda tricky to navigate, and some of the local Security Zones. The USCG has set up a large recreational boat exclusion zone in Tampa Bay. They have defined the zone using Lat/Long corrdinates that I have plugged into my GPS as waypoints. I made the series of waypoints into a route so that they are connected and the plotter displays the route.

Have fun with your new boat! May I also suggest a USCG Boater Safety class?? Even if you're an old salt, you can still learn something. My boat insurance was discounted 10% because I had the certificate of completion from a boater saftey class.

work2fish-Thanks for the input. As much as I would like it to be this is not a new boat.I've been on this bay for 13 years now. The only thing new is the plotter. I know my way around ok but got stuck in a nasty fog one day last year and finally ponied up for some electronic help. There will probably be just a handful of routes that I'll keep. My biggest fear is running into a stealth buoy at night.
