Thanks all

I tried using my phone (Verizon Droid) but there is no speed reading available on it.

I have three GPS units, One in truck and two for flying. Also, have a Garmin 296 for marine, land & air use that died.

As far as the wheel getting clogged; We plan to take the boat to different lakes throughout the summer so keeping it clean will not be a problem.

Scott. I have a trailer and will be pulling the boat today. I have several items to work on. It will be in my driveway back by my shop for a couple of months.

Which slip are you in?

Now that the lake is coming up, we're really close to getting Eddy out of that cove. We tried last night but grounded. Lake is at 647.82 this morning....was at 647.6 last night. We're gonna try again at 648.25.

Once out, Eddy will need a slip for her for a few days until he can get her pulled or find a permanent home.

 With all due respect to the person who bought you the speedometer I'd use a GPS and forget about a hole in my boat.

Does anyone here know why a paddle wheel is useful even if you have a massive plotter?

When used with a GPS it measures speed thru the water versus speed over ground.

Drill a hole - use 5200 and call it a day.

On a lake (that isn't part of a river), speed through the water is virtually identical to speed over the ground. <blockquote id="quote">quote:<hr height="1" noshade id="quote">use 5200 and call it a day.<hr height="1" noshade id="quote"></blockquote id="quote">Grrrrr...

You need to download an app to your Droid phone using the android market. They're mostly free. Just a few days ago I installed a knot meter to my G2. Like mentioned, its relative to land by gps signal.

95% of the C25's here have factory instruments, and how many have leaked over 30 years? What's the big deal?

Scott

I was in D3. I pulled the boat yesterday. My slip lease is up the end of January. I may not bring it back to EML until this fall and only if I can get a 90 day lease.

Okay....I think Eddy only needs a few days to arrange getting the boat moved to Joe Pool. If we manage to move the boat today (Lake is 648 this morning) we'll put her in D3, if you don't mind, and I'll get with Linda on Tuesday. There's only 3 empty slips right now, but Linda said a few folks will be going back to Harbor One soon.

Missed that part, never sailed on a lake, but I am claustrophobic.

Would you define "drift" for me Dave? Whether you're calculating a destination or racing I'm thinking the only thing that's important is speed over land. Help me understand if you would.

It only helps with "drift" as Dave described it when compared against a knotmeter. The difference between knotmeter speed and speed over ground is your drift. How fast would you move without propulsion of the motor or sails.

The GPS will also help you know how much leeward motion you have when compared against your compass.

John said it... As for the terminology, there are two terms associated with dealing with currents: Set and Drift. Set is the direction of the current, and Drift is its speed. When you know both, you can determine on a chart the bearing of course that, at a particular speed through the water, will take you to a specific point, and you can figure out how long it will take to get there. It's all in books and courses on navigation.

Or better yet, you are doing 10 knots over ground and 7 thru the water with a 3 knot current pushing you.

Calculating Set and drift is almost unnecessary now that everyone has a plotter. If you are navigating by compass alone, or with a sextant, radio directional finder - anyone know how to use one? - then you really do need to calculated Set and Drift. Although I do know of some big yacht racing crews who have a navigator doing it old school for tactical reasons.

I just point the boat and go.

<hr height="1" noshade id="quote"></blockquote id="quote">Me too--at 25 knots, a 3 knot current doesn't mean much (except where it makes water fly in the air and waves stand up vertically in The Race or Plum Gut.)
