Finally, the "Perfect" Tide Clock...

I've probably moaned and groaned before about not being able to find a tide clock that is tied into NOAA tide tables, and doesn't depend on a lunar analog clock motion. The tide clocks we all have that are "clocks" with a lunar clock in them so the only 2 times a month they are deadly accurate are at the New Moon and the Full Moon, assuming of course that you set them at one of those 2 times.

Why? you may ask, doesn't the Moon drive the tides? Well that's mostly true BUT the sun's gravitational pull is also a factor, so the tides are most extreme when the Moon and Sun are either lined with each other (New Moon) or directly across from each other, (Full Moon). When they're at 90° from each other we get Neap Tides, which are not very extreme, and not necessarily even close to the time that one's analog tide clock would say. Mine can be close to an hour off the actual time of the high or low tide. Even more "unusual" is that sometimes in the mid-lunar cycle, the AM and PM tide will be almost exactly 12 hours apart instead of the more normal 12 hours and 14 minutes for my location.

The tide data on our GPS/Sounders is directly taken from the NOAA tables for the area you are in. There are cell phone aps that do the same, but I had a bear of a time trying to find a home tide clock that did this. At one point I was so desperate I was ready to take one of my older computers and write the program for myself, but didn't want to try to sell that an old computer needed to be displayed to the Ministry of Sociality and Finance.

I got excited a few years ago when I did find such a clock, but it was well over $300 and it had no "decorative value" that I could us to convince the Minister to approve a Capital Request for the clock. Honestly, at that price, I really wasn't interested either...

Well my prayers have finally been answered, Thank You Poseidon. NexTide.US out of MA has devised a WiFi enabled tide clock that provides even more data than I could imagine. Of course it shows you if it's flooding or ebbing along, with the time of the next tide, BUT it also shows the magnitude of the next high and low tide in terms deviation from MHW/MLW. The price point is 1/3 of the one model I rejected, and its "palette" is one of many lighthouses, the number of which increasing by the month. Additionally, there's some other styles including Surfboards, Bodyboards, Pineapple, Dock Piling and, believe or not, WWII Fire Control Towers, you know that tower next to the Montauk Lighthouse!! You can tie the clock into any NOAA tide reporting station, it's not at all locked into the tide of the lighthouse casing!! Besides desktop models, there are a few "Big Bertha" wall mount versions. I can't think of a fisherman or boater who wouldn't want one of these at home to replace those relatively worthless analog ones. Go to their website to take a look!!

I discovered the website over a month ago and hoped they would eventually add the local Pemaquid Point Lighthouse, my "Good Morning" lighthouse to their product list and today they did!! Of course I immediately ordered mine today and am already pacing waiting for delivery.

Just can't wait!!

I must admit, Roccus, that sounds like a really nice clock and offers some really cool graphics a s well.

This old "cheapskate" still relies upon the Eldridge Tide Pilot book, which I have always found to be the most accurate of all the published data. Only one time I can recall in decades of using this reference book did I see a variation from its prediction and that was on a day when a nasty Nor'easter was starting to move in. Other guys I spoke with that day told me they observed the same strange phenomenon.

ABSOLUTELY, old salts never change their habits, they just accrue more as they age!! I would never suggest that NexTide would replace Eldridge. It's just something I can peek at for a quick tidal assessment, and the Admiral can look at and be pleased that it's in alignment with her decor scheme.

AAMOF, on my office bookshelf there still is my "Trilogy" of nautical must haves, "Ashley's Book of Knots", Bowditch's "The Practical Navigator", and for nostalgia, my very dated (1983), and tattered copy of Eldridge. In reality, the only one that's more than just a trip down memory lane is Ashley. Every knot you even didn't need to know how to tide, including nooses and bow ties!!

In my rag sailing role as boat "Naviguesser" in the days of the dawn of Loran-C, the "yellow book" was always at hand. Now in the world of GPS displays of currents, which are minimal at best, I'd still have a copy handy if I did any serious long-distance navigation with the full intent of knowing every possible impact of tide and current.

However, being a fisherman first, I amassed quite a library back eddies inshore at Orient that weren't in Eldridge. Too funny to watch a fleet of blow boats fight 3 kts on the nose, while we were in a sweet spot of 2 on the transom. I'm sure you also have quite a list that can't be found in Eldridge...
 
Hmmm, my 73rd is coming up. I often notice the tide tables from the town the newspapers or the weather channels are off by an hour or even more when I am on the backbay in the yak most mornings from May to October. How does it adjust for DST ? (You know I had to ask, even though I rarely fish during the colder months...)
 
Here's a shot of mine, partially obscured by the wheel. DST has to be manually adjusted in this analog clock. Works great. One AA battery per season.

Unsure why you would have one on board when your GPS would have far more accurate data? Unless the dash one communicates with a database, and since you have to adjust DST, the tide part is probably on a lunar cycle and therefore inaccurate during the neap tides.

I have my phone AP & and my GPS tides when I'm trying squeak onto my dock without making a channel. The NexTide is for home to look at as I dash out of the house...

How does it adjust for DST ?
Gets if off the NOAA data base...

The entire subject concerning tides, tide cycles, high and low water vs,. current flow is far more in-depth and nuanced than many people realize. So, Roccus, you are correct in noting that certain geographical locations have an effect, sometimes small and other times sizeable, in the strength of the current pushing on your vessel.

The angler who is really on top of his game does keep a log of these fine differences from the published data based upon their own "on the spot" observations. And the only way to really acquire this data is to be physically at the given spot with your boat and making notes. One special circumstance comes to mind when I am piloting the 55' Orient Star. The dock where I pick up and drop off the camp kids is in a cove on the NE corner of Shelter Island. There is a back eddy there where land formation and the nature of the water flow pushes the boat the exact opposite of what you would expect deepening upon the stage of the tide and wind/speed and direction. Took we a few tries to realize what was going on there when I first took on that job 6 years ago.

Also, I agree with Lep's comments about his manual tide clock on the dash. Sometimes have a quick and dirty reference to what is happening is enough. Plus, I always like to keep my "fish gurve coated fingers off those beautiful touch screens!

That's EXACTLY why I refuse to have any touchscreens on my dashboard. I can easily clean dirty buttons, and my cell phone screen, but I don't want to have to "read around" chunks of fish slime when I need data off the screen...

prefer a quick glance down,
When I'm looking up the tide on the GPS it's because I'm trying to figure out exactly how much time I've got to either squeak on/off my dock, or how much time I have to kill prior to leaving/return. So I'm either standing still or doing harbor speeds. Never any worry about bouncing at 20 kts which means I'm out of the harbor. As soon as I'm at the harbor entrance I'm in 40' of water which drops to 100' within 200 yds. The depth finder depth is more than adequate in those conditions.

Yes, I know, pretty soon I won't have the option of not having a touch screen. Maybe I'll be buying used electronics off of Ebay then...

eBay electronics are one way to go, but it's my observation that at least a few of the major manufacturers realize the problem of going only touch screen on boats. When I upgraded my Sonar/GPS/Plotter machine 3 years ago I specifically went with the Simrad NSS evo3 because they offered both touchscreen and nice rubberized buttons so you could keep the screen tidy. I believe Garmin, Raymarine, and Furuno have all gotten this message and now also offer combined input mechanisms on some of their models. However, a few are somewhat restricted in the number of hard-wired commands. Some seem to think a multipurpose wheel type key can suffice but I'm not convinced. Hence, I made the Simrad choice.

There is another important reason for not getting boxed in to a touchscreen only set up. On small to mid-sized vessels when running at speed or in choppy seas it is really tough to make accurate inputs without hitting a function you do not intend to activate. Sometimes "old school" is best!

Finally, Roccus, I realize that in your part of the country the tidal differences are much more dramatic than by me. If you miscalculate you could find yourself "walking" home from that hot Bass bite!:D

Glad that "buttons" are still available. I have a tough enough time hitting the buttons at 20 kts in a chop. Navigating a wheel would necessitate throttling down...

Chalk it up to people who never boated and/or fished, designing things for "looks" instead of real world practicality...

A perfect quote.
 
Between the tide flooding from the east river, and flooding from the eastern sound, and the north/south orientation of the bays, and the string of islands from City Island to the east, it gets pretty tricky to figure out which way the water is going to be flowing in the extreme western sound, and it keeps changing all tide long and day-to-day depending on moon phase.

Wow, never thought of that as I rarely fish up that way. A bunch going on!

That's why Poseidon invented Eldridge Tide & Pilot book, but nothing besides years of boating and logging the info will provide better data in complex places like that.

Regardless, I just got the clock fired up and am very pleased. The LEDs tell a story, the blue ones in the middle make a down wave, just like the light rotating right to left, which both mean ebb. During the flood, the actions are reversed.

The bright LED on the top of the line is today's high tide mark, which is Abbey Normal low, bizarre for a tide so close to the full moon, and same goes for the last blue LED in the line, showing a above normal low tide mark. The bright LED is the 6:30 mark, meaning the next tide event, low, will take place from 6:15 to 6:45, 6:18 to be exact, but each LED has a 15 min +/- window.

Holy Chit; you need a PhD to interpret the data from that baby!:ROFLMAO:

In all honesty, that is a beautiful piece, Roccus. In my mind it's a whole lot more interesting to watch than most of the crap on TV.!

Hmm I have a birthday coming up soon; maybe time to start dropping some hints...

If you want to keep it local, they do have the pattern that embraces Block North, Plum Island, RIP, Sheffield Island & Morgan Point, along with Montauk & Fire Island...
