One handy little tool sailors often forget to consider as a navigational aid is the simple orienteering compass
which one can get for about $7.
Laid on a chart, one can take a bearing. A dial allows you to easily compensate for magnetic variation. The direction of travel arrow can be pointed at an object and used to take a hand bearing, almost as easily as with a hand bearing compass
. It can be placed parallel to the center line of a boat and used as the ships compass. It' small size makes it easy to use on a folded up map in the cockpit
I'm not recommending by any means it should be used to in place of traditional navigation
tools, but it for trailer sailing or day sailing
it can offer a cheap
back up to line of sight navigation
. It can easily and cheaply be kept in the cockpit
and used as a quick tool to verify GPS
settings, and at $7, it's an extremely affordable backup, even if not quite as accurate or simple for each task.
I've used one out sight of land in both sea kayaking and sailing.
