Northeast - Where to find maps.....

Where would I find maps showing the 700 Line and the Canyon from BI and Montauk.
Thanks

They are called charts, and you can find them online at geogarage.com.

Btw, why the 700 line?

Cool site....

WHY can't we get RID of the dang red squiggly lines marking underground cables????? KRIKEEEEEE!!!

Captain Seagull Charts are available at a well stocked B&T, ships stores or West Marine. The last curve on the maps is the 100 fathom curve then it drops off big time. If you go past the curve at the East or West Walls the bottom falls off to 1400 feet. Could be tricky to find 700 feet for any length of time. Bump this up over the weekend and you should get more reponse from canyon runners.

I think he's looking for the Loran C 700 line.

Do nav charts still show loran lines?

You may have to hunt around to find those.

I haven't found any on line..... I might have some in attic that are still readable:)

Maybr a good map will shoiw the loran lines

I think the Seagull chart you want is Catalog # NY 1003, Version 2. They may still have some in stock.

Nothing like full size paper charts. Capt Seagull is garbage. Can't really navigate with them.

Is the question about fathom lines or loran lines? Loran locations are often referred to as squares, but a 700 square would be very close to Jones Inlet. There is an occasional hot spot at the Hudson Canyon referred to in the past as the 100 square. It is at the southeast corner of the canyon, referred to as the elbow. The fishing is done on the 70 to 80 fathom "flats" just north of the elbow where the current wells up from the "500 fathom point" at the mouth of the canyon. The Lat/Lon of the square is 39.30.865/72.10.981. It is a haul from Montauk. There are other canyons that could be a better shot for you. John Raguso, who writes for The Fisherman, has a book out on the canyons off the northeast coast. The price of the book would be well covered by the cost of the fuel saved.
I was curious and posted a question on noreast.com. Most of the above was distilled from answers I got there.
