I suspect someone out there has done this already and I'm hoping to learn from your experience. Please bear with this long posting as I think you need some background to fit your advice to the problem. I sail out of Boulder Marina on Lake Casrlyle, Illi

Bob, not that you wouldn't want the additional functionality of a GPS/chartplotter, why don't you simply use a basic GPS receiver like a Garmin 12 or 76? You could enter a route that takes you safely out of and back into your marina. Both of these woul

No chance of using local knowledge as a low tech (repeat: cheap) alternative? Can you find a few objects on shore to fix a line of position that avoids the reefs. e.g. "Keep the flagpole to the right of the big fir tree", something like that. Another wa

Use a cheap hand-held GPS and mark your way points. I have five channel markers coming into my dock. I can come in during a fog using the way points.

I have an old Garmin 48 GPS and it has never failed me. It always finds the bouys in the fog. I remember once we could barely see the bow and without the GPS our overnight would have turned into a three day trip. I have a request for a Garmin 76 with W

I also use the Garmin 48. Once I have been over a route and made the inputs to the GPS I can repeat the route at will. From Point to Point. Other options include making entries onto the GPS where the reef is so you can avoid it. You will also be able to p

At our lake, the State Division of Natural Resources personnel have marked the shallow areas that might damage our boats. Talk to them about setting a couple of marker buoys. Why should all the sailors have to buy expensive gear to avoid the spot, when a

Bob,
I use a Garmin 48 and find it exceptionally accurate. As someone else has stated waypointing critical bouys leading back to home port is like a roadmap when fog sets in. I assume that waypointing the shoal in your area would be a prudent means to

I like Val's suggestion of dealing with your situation... identifying not so much the waypoints that will safely take you thru...but rather marking the shoals. And, unless they bother the power boaters....there will be a reluctance to mark them especiall

One more feature of the Garmin 48 (and I assume the much cooler 76) that wasn't mentioned is the "proximity waypoint," which will sound an alarm if you get within whatever distance you specify from the waypoint. You could create a series of proximity way
