That's what came too my mind too. It's true that tides/current almanachs show tides data for a set of hours (1,2,3 o'clock etc.) but you have to interpolate the time between these charts.

I think having a map showing tides/current arrows just gives an indication what to expect. This would simplify planning your trip, though you still have to check almanachs with tides and currents tables/charts.
The same goes for papercharts! I would never leave habour without them! Even if I have my iBook running and showing my position: I still refer to papercharts just in case.

I think that hits on it. YOU are doing the interpolating. If you're wrong, you can sue yourself. Sorry state of affairs, particularly here in the litigious US, but so it is.

I've just returned from several months of fishing in the central Aleutians where the currents are at least as bad as in the San Juans. I find it odd that you would worry so much about NOAA warnings on interpolation. The published current tables for the Aleutians aren't based on interpolation; rather, they are based on extrapolation from the few accurately measured stations in the eastern Aleutians. If NOAA extrapolates its own tables then a bit of interpolation can't be so bad.

Your discussion sort of misses the point that in many cases, anything is better than nothing at all. Most commercial fishing boats run Windows nav packages that do include current vectors in their displays. Nobody sees them as the gospel truth, but they do add a visual reminder of somebody's initial estimate of the situation. Despite the inherent inaccuracy I think the lack of current vectors is my biggest point of envy with the Windows packages.

Current vectors will never be perfect, and that is no reason to shy away from them. In the end they're not so different from weather forecasts. Ideally some easy way would be provided to alter the slack times and peak current speeds for individual arrow symbols so that familiarity with an area would eventually lead to reasonable accuracy. Maybe current vectors should be presented as a personal mapping tool rather than a statement of conditions. I'd really like to be able to make my own.

What about Mr Tides for iPhone & iPod Touch. Safari-based, I guess.

Hi Folks

I've been enjoying this topic a lot as it's near and dear to my heart. I enjoy a sport called Predicted Log Racing, also known as Cruiser Navigational Contests. Tidal currents are its life blood and knowing what they will be means the difference between winning or losing. I've been log racing since 1986 and I've used every piece of tidal current information there is, you name it I've used it. It's my opinion that as for predicted speed and time of that speed it's a crap shoot. I call it guesstimating. However the direction arrows or what ever the information uses to show direction is pretty close to true. So what ever program you use, take the speed stated with a grain of salt, but it's direction stated will be in most cases pretty good. Just my opinion for what its forth. To learn more about Predicted Log Racing check out this web site; http://www.ipbalogracing.org/default.htm

Mr. Tides exists as Widget for OS X. So programming it for the iPhone/iPod Touch should be no problem. At least I think so.

Direction informations would be enough for my use even if the speed isn't accurate.

We already have the same info for wind directions with GRIB files and weather infos in GPSNAVX.

OFFICIAL: Third-party apps coming to iPhone

"Let me just say it: We want native third party applications on the iPhone, and we plan to have an SDK in developers’ hands in February. We are excited about creating a vibrant third party developer community around the iPhone and enabling hundreds of new applications for our users. With our revolutionary multi-touch interface, powerful hardware and advanced software architecture, we believe we have created the best mobile platform ever for developers.

It will take until February to release an SDK because we’re trying to do two diametrically opposed things at once—provide an advanced and open platform to developers while at the same time protect iPhone users from viruses, malware, privacy attacks, etc. This is no easy task. Some claim that viruses and malware are not a problem on mobile phones—this is simply not true. There have been serious viruses on other mobile phones already, including some that silently spread from phone to phone over the cell network. As our phones become more powerful, these malicious programs will become more dangerous. And since the iPhone is the most advanced phone ever, it will be a highly visible target.

Some companies are already taking action. Nokia, for example, is not allowing any applications to be loaded onto some of their newest phones unless they have a digital signature that can be traced back to a known developer. While this makes such a phone less than “totally open,” we believe it is a step in the right direction. We are working on an advanced system which will offer developers broad access to natively program the iPhone’s amazing software platform while at the same time protecting users from malicious programs.

We think a few months of patience now will be rewarded by many years of great third party applications running on safe and reliable iPhones.

P.S.: The SDK will also allow developers to create applications for iPod touch. [Oct 17, 2007]"

Thanks to everyone who's posted! Based upon what you've said, I'm working on a way for Mr. Tides to generate a list of current stations in an area that will give the value and direction of the current (based upon whether it's an ebb or a flood and what NOAA says the direction is) and export that information via AppleScript. This will let other programs query Mr. Tides for the vectors and display them. I might include current arrows on my maps if I can figure a way to do that too, but I want to stay focused on tides and not navigation.

As for the Tide Widget, I'm going to work on an update for Leopard that will look pretty good (a mockup by another person is really sweet!) and hopefully get that out soon.

As far as the iPhone, as soon as the SDK is out I'll start working on something. It'll be based upon the widget, if that's possible. I'll know more when I actually get the SDK.

Hi August,

Wow great ideas! That's what I wanted to hear!
So we will see tides arrows in MacENC then? Please, please! Mr. Ray ;-)

Keep up the great work.

BTW where can I donate for Mr.Tides?

Regards,

Manou
