I like to go places other boats don't (or can't). Sometimes this has a negative effect on the condition of my bottom paint
. And seeing a rock on the chart is not much consolation. I want to know exactly where that rock is.
I find myself wanting a portable device with a gps
and depthsounder that I can use to reconnoiter an anchorage (or a channel) in the dink before bringing the big boat in. Ideally this device would create a bathymetric chart that could be used for navigation
. And maybe have some buttons to indicate obstructions or bottom type at a particular location (sand, weed, coral
, etc). It might as well beam the data back to the big boat wirelessly in real-time so it can follow behind instead of having to wait for the dinghy
to return. Of course the charts
should be saved for re-use and should also account for tide.
So, does such a thing exist? I've seen the Brookhouse data logger, but I'm hoping to find a more complete solution.
Since I'm likely to get it anyway, I might as well welcome any appropriately salty advice for how to do the same thing without electricity and geosynchronous satellites.
