I hope this doesn't come across as prick-ish because that's not where I'm going with it. I remember a thread from you recently where (I think) you're basically trying to get up to speed with the boat and the whole sailing thing and I think that's awesome. I was in the Navy
and my dad was a Marine
aviator in Vietnam
so if that's you in your picture I imagine you've been getting abused with all the Afghanistan/Iraq operations.
pilots receive official training, licensing, and constant re-examination. The aircraft themselves are inspected, professionally maintained, and certified. This is more than one licensed operator at any point in time (in most countries), frequently two of which are at the controls at the same time during difficult maneuvers.
So saying "x works in aircraft so x works in sailing" glosses over a lot that simply isn't true in the maritime world. The Navy
, as an example, is not allowed to steer warships around without paper charts
and without the professional trained navigators who know how to and actually do use them.
You didn't come here for a lecture so again sorry if it's coming across that way. But before I'd get into expensive navigation
I'd be asking questions on deduced reckoning, chart scales, and where to get paper charts cheap
Again, sorry if that's preachy. Good luck either way. And to be honest integrated electronics
like you're talking about are pretty expensive.
The cheapest route
with a usb gps
. That's at least a chart plotter on a laptop
