Wow! You can get by with only one waypoint every 50 feet?!? Well, I
suppose there is a certain appeal to this sort of asceticism. ("Less is
more", and all that.) Personally, I don't like to limit myself in this
way, particularly with the new WAAS-capable receivers that have an RMS
error of 3 meters. I prefer one waypoint every 30 feet or so.

I'll let you in on a little secret: Use some of that money to buy MORE
GPS RECEIVERS! Then you can increase your waypoint capacity up to the
weight-carrying capacity of your kayak, minus weight of the paddler,
divided by the weight per GPS receiver, times 500.

I hope this is of help.
