Re: Handheld GPS for anchor alarm?

I the garmin 7* series can connect to a PC. The ones I have provide for an external antenna and a PC connection.

By the time you desl,with the PC connection and the power overhead of a PC, the iPhone or iPad may be cheaper.

Re: Handheld GPS for anchor alarm?

My garmin Colorado cost $100 on ebay and the alarm is loud enough to wake me. I keep it plugged in using a cheap micro USB cord (and 12V USB adaper), with Alkaline batteries for backup. If it loses external power it automatically switches to the internal alkalines.

Re: Handheld GPS for anchor alarm?

If you're simply looking for a device to be an anchor alert and have an iPhone or iPad download an app --Anchor Alert or The free Drag Queen. (The iPad needs to have a GPS, either internal or external).

Re: Handheld GPS for anchor alarm?

I really need to spend more time on the forum instead of going snorkelling, drinking and sailing because there are some really greats suggestions in this thread. Thank you for the ideas.

Re: Don't Forget . . .

to set your GPS to where you dropped the anchor and not to where the boat happens to be when you "set", the anchor.

I never use one. I ensure that I have sufficient scope and am well set. I sleep better that way.

Bob, Connie and jackdale,

I agree. I wrote this on another forum about anchor alarms:

************************************************** *

I'll start off by admitting that I am odd. I anchor in two of the same places on an almost weekly basis.

Both are protected "basins" that have little change in wind and/or current.

The wind is usually from the west or northwest when I anchor, and in the morning I wake up with the boat facing east with little or no wind.

Sometimes I'll anchor in a different place where the current changes and have reported on those techniques, in reply to John R's comments, in the Sailing or Cruising Discussion forum. Anchoring lesson learned - Catalina 36 International Association Forums

I have also anchored in tidal rivers with reversing currents, fore and aft.

Perhaps because of the predictable winds, or lack thereof, and no storm fronts moving through, I never hesitate to go below after the anchor is set (by backing down on it) and have a quiet peaceful night with no interruptions.

Only twice in the last 14 years have I ever even thought about setting an anchor alarm, and that only to see what would be recorded on the GPS track feature.

Perhaps I have the advantage of having good anchorages that I frequent, but I simply have no need to use an anchor alarm, or get up in the middle of the night.

I am sure that if I was in a different part of the country, I might use one, if regular major wind shifts and velocities occurred.

I find that good anchoring gear and knowledge of the paces I anchor in makes a BIG difference.

Anchoring in undemanding places helps, but an anchor is never 100% secure and I am always puzzled by those that don't use the insurance policy of an anchor alarm. For most boats there is no extra equipment to buy, with the right gear minimal power consumption (about the same as an led anchor light).

You should sleep better knowing your GPS "crew" is watching out. I do.

Re: Handheld GPS for anchor alarm?

I myself an pretty new to sailing and find the anchor alarm reassuring. On our last trip we were traveling and around noon at the last designated anchorage on our chart we knew were were not going to reach another during daylight. Sailed until the sun started to set and then found a nice spot outside the channel and dropped the hook and turned on the anchor light and set the alarm. I was awakened at 2am by someone in a powerboat spotlighting us as they motored by, probably shrimping. It is nice to be able to stay in my rack and look at the ipod and know we have only moved 30 feet and since the bearing to the anchor has changed the movement is probably just a wind change. I bet I would have felt it if spotlight guy had run through my rope rode, but you never know.

If I am that unsure of my set, I will set an anchor watch and have done so. After we dragged in Mexico during the day, we set a watch for the night.

I sense that much of this discussion is about a technological imperative, if a technology exists, we need it. This is found in healthcare especially, and I see it in boating.

I learned to sail without GPS. I bought my first one (Garmin 48) to deal with fog. I would rather use radar, but many of the boats on which I teach do not have it.

With an anchor alarm I have one more thing to worry about - does my anchor alarm work?

As someone pointed out earlier, the alarm has to be set when you are directly over the anchor.

Re: Handheld GPS for anchor alarm?

Good day All, I use my Garmin 76 when we're on the hook, I wired up a 12 volt female receptacle in our stateroom near my pillow, when the alarm goes off, I simply turn my head, look to see if we are dragging or simply swinging, and cancel the alarm. If I see a ' MOON CRESCENT' on the GPS screen, I know we are fine, BUT A PINE tree design on the screen, I know we have to go top side and have a look. My two cents worth.
