2009 tides and currents - Maptech OSN?

[jackdale]

I have been using Maptech's Offshore Navigator with Canadian Hydrographic Service charts. Does anyone know where I can get 2009 tide and current data? Or am I looking at getting new software?

Thanks

Jack

My version of Tides and Currents goes until something like 2020. Does not have to be updated every year.

The tides and currents on both my Cmap and Navionics charts around the East end of Long Island Sound are completely off and therefore unreliable, at least they never correspond to what I actually "see" out there as I sail.

I am curious to hear from others in the region if they find the digital information accurate or not.

I'm only out that way once or twice a season, so my experience is somewhat limited. But I find that my Garmin and Nobletec are pretty accurate. I still check them against Eldridge...old habits die hard.

I went from Cape Cod to NJ and back in the fall of 07 and found the digital MPTECH tide data to be fine.

If you actually bought the program. I believe you can download the new tides?

I have a legit, registered copy.

Maptech has gone out of business. I believe they got the tide and current data from some other source. I can get tide and current data from the CHS tide table (the official source). I also use Tide Tool on my Treo cellphone and Xtides on my PC. I would like to continue to have the current data integrated with my PC based charts. That provides my students with another representation of the information.

THis is from Richardsons Charts from an email sent to me today.

The 2009 Tide disk is now available for Offshore Navigator customers........$25 for an actual CD.....
The free download *should* be on the web next week......

Is the any chance you can post the link when it is available?

merci mucho

it amazes me that people actually feel a need to buy tidal harmonics software when there are so many legitimately free applications for unix, windows & pocketpc available. i'm currently using ctide on my pocketpc (primary computer), jtides.jar on my linux laptop (much better than xtide) and wxtides on my virtualbox xp desktop running on linux. all of these freeware applications use global harmonics tables and are good until at least 2038. i've helped folk setup maxsea, cmap & some other rubbish which starts with t.. all of which have tide & current data incorporated, of those i've found maxsea v10+ to be the most accurate.

maxsea stands in its own, valid for years

I use a variety of tide and current tools when teaching. I have Tide Tool on my phone and Xtide on the laptop. The CHS Tide and Current Tables are my "official source." I like the visual integration of the current data in Maptech. This image, for example, shows how the flood current from the north and the flood current from the converge in the vicinity of Blind Channel. North of this point on Vancouver Island portion of the inside passage the "red right returning" rule is governed by the General Direction of Buoyage which trumps the upstream rules.



So has anyone seen where the 2009 data is available? I could find nothing on Richardson's Charts or the old Maptech site.

What other software has this feature? I have skimmed the maxsea site, but the price may be out my league. The OSN tide and current features seem similar.

Bruce?
"it amazes me that people actually feel a need to buy tidal harmonics software "
Which of your free products INTEGRATES into mapping software, showing currents acrossa a 100-mile wide area by station and tides by height, so that they can be used by the navigator while working actuvely on the charts?

And then, which of them actively integrates into the route planning functions of that software, so that I can lay a route from "A" to "B" and have the software also integrate the tidal currents to correct my groundspeed during the route? (Something much of the nav software doesn't do, just some can.)

I'll use WXTIDE for a local race or clearance into a marina, but "horses for courses".
