Update on GPS usage in US coastal waters. After carefully reviewing the relevant navigational literature and after consulting several experts in the field of electronic kayak navigation I have learned a few things which should have been included in my original "electronic charts?" post. Fist of all, my initial estimate of using one GPS waypoint per 50 feet is apparently inadequate. There appear to be too many unknown variables on the open and inland seas to allow this kind of "one size fits all" waypoint management scheme. I have been informed that there may be certain circumstances where a tighter GPS grid is indicated. Specifically, a Department of the Interior source, SCU (Special Coastal Unit) has indicated that the Astoria, Oregon area may be particularly hazardous to the paddling community and should only be approached by experienced paddlers with the latest GPS technology and an extremely tight (30' or less) GPS waypoint grid. I was informed that Dave Kruger, in particular, is not to be approached without adequate backup nor should he be detained for any reason without an impressive array of GPS receivers. An investigation is underway to determine whether or not a 30 foot GPS waypoint system would adequate to secure safe passage through this hazardous area. Paddlers are advised to use extreme caution.
