rmeador All of you who posted websites, thank you very much. I'm especially interested in GeoGarage. I think that will do nicely for my purposes.

Regarding that boat I like, I think you have all convinced me that trucking it over land is the right solution. My broker estimates that it would cost less than $3k, but that isn't an official quote from a trucking company. I'm still looking at other boats, and I am trying to look locally, but I looked at one locally that I really liked but it wasn't in great condition, so I found this other one that is the same brand/design but further away and appears to be in excellent condition... I need to go look at it in person eventually though.

ambianceack There is a cruising guide of Lake Champlain which talks about the Erie Canal etc. The canal connects the hudson and lake Champlain. If you travel with one or two experienced people you could probably sail all night on a few occasions and shorten the trip.

Google Earth will not get you anything special, and anyway it's a browser plugin nowadays. Google Maps and Geogarage both work fine for me on Firefox on Linux, and they'll do exactly what you want.

Believe me, I spend lots of time that should be spent working by doing the "dreaming" kind of planning

As for the trip home if I bought that boat I mentioned,
I think there is a connection, but I would hardly call it navigable. It looks terrifying.

If I were you, I'd buy local. When I was first in the market for my boat (first and only), I looked at a boat in San Diego. I did the "dreaming" kind of planning and "realized" that it shouldn't take more than two weeks. What I didn't know at the time was how difficult, uncomfortable, and dangerous those two weeks would be. I ended up buying a boat in Seattle - a three day sail in principle that ended up taking three months. Go local

legarots Running Routes - WalkJogRun lets you plot a course, enter your speed, and it will give you a duration. Of course, speed is in mph, not knots, so you'll need to convert.

rmeador I'm mostly interested in the "dreaming" kind of planning. Just figuring out if it's even remotely possible for me to get somewhere in a reasonable period of time. I realize most people enjoy sailing for the act of sailing (and so do I; that is the primary reason I am getting a boat), but I do still want to take it places, not just sail around in a circle all day and go home. I like several of the options you guys have given me so far. I'll have to see about installing Google Earth on my computer... I run Linux, and last I checked (over a year ago), they didn't have a Linux version, but maybe they do now.

As for the trip home if I bought that boat I mentioned, I hadn't give it a whole lot of thought as I was looking for a tool to assist me. Initially I didn't think it was possible to get to the ocean from there, but my broker suggested I could go down the Hudson, out NYC and up the coast to Boston. Looking at the maps, I don't see a navigable connection between Lake Champlain and the Hudson, so I'm not sure what he was talking about... the St Lawrence might be the only option.

svHyLyte One can easily measure an entire route using the Ruler tool in Google Earth. One can also select the units of measure--either statute miles, nautical miles, meters and kilometers or what have you. There is no particular reason why one needs actual distance over the ground due to tacking as what counts on up-wind legs is VMG which detemines trip time. If needed for academic purposes, however, you can calculate the potential distance of the upwind legs to account for tacking although, for most yachts, one can safely add 25% for up-wind legs and be in the ball-park.

For example, the distance from the south Tampa Bay Sea Bouy to Smith Shoal Light off Key West is about 180 miles. In a 12 knot southeastly we'd be beating on a port tack at about 35ļ apparent making roughly 8-1/2 knots but with a VMG of about 7. Assuming no wind shifts (which is silly as the wind almost always goes east as one gets further south) it would take about 26 hours to cover the leg (the important number) during which we would have sailed roughly 220 miles over the ground or about 22% more than the actual distance.

FWIW...

losesightofland I still think old school is the best way. As much as I use electronic navigation on the fly, I still do a majority of my planning with a chart, dividers, and a pair of triangles. If you don't know how to use these items yet, put it on top of your to-do list! There are infinite resources out there for learning basic navigation, so I can't recommend one over another. With just a few basic skills, you'll have no problem planning trips quickly and efficiently.
