  1. At the time, I lived in Kittery so I was able to scout out the landing in advance. I landed south of the bluff at 43.14482,-70.626936 and camped the site near the bath house, at 43.145826,-70.626716. The trip was a fundraiser for the National Brain Tumor Foundation and the campground owner made a significant donation. And, I chose to avoid the stealth sites as they are mostly quite sensitive, either part of the Rachel Carson NWR or private. Besides, I could have easily just gone home for the night. :)

  2. There is a very tempting pond on Bois Bubert, but it is private. There is no potable water at Roque Island State park. There is water at the town campground in Jonesport (it's trucked in) and wonderful hot showers and laundry at the marina. There are closer to 30 miles of trails along the bold coast, but I'm not sure if there is anywhere to get water.

  3. In some places, the wind can also change the direction of the current.

    The direction of the ebb and flood varies in passages tending east and west. In Fox Island Thorofare, the flood comes in from both directions, meeting at Iron Point, and it also ebbs in both directions. In Eggemoggin Reach, the current floods northwest and ebbs southeast (see Penobscot Bay). In Deer Island Thorofare and Merchant Row, the current floods east and ebbs west, but strong winds can reverse the flow (see Mount Desert Island region). In Casco Passage and Moosabec Reach, the current floods east and ebbs west. At Bass Harbor Bar, the current floods west.

  4. Pre-programmed BlueChart chips come ready to use in your gps unit, but I'm pretty sure they cannot be re-used on more than 2 gps units. The chips come in 3 zones, Americas, Atlantic (europe) and Pacific (asia). The chips cannot be uploaded to your computer.

    The CD can go on your computer and get downloaded to the gps chip.

    I didn't like either BlueChart method and use the basemap with the oldest version of their TOPO software. The discontinued US TOPO installs on your pc and downloads to the chip with out any unlock codes.

  5. ...The unit may not do as well if immersed, etc. and if in a bag is likely to float. ...

    The 76csx does float, but Murphy's law dictates that it will always float away from you! I used mine for about 4 years without a bag. Eventually, the seals in the battery compartment failed and the terminals corroded. The USB seal also failed. The serial port did not fail. No water ever got into the unit itself.

    So: either keep the gps in a bag or inspect and replace all the seals when needed.

  6. ...Personally, I reckon that if GPS is that wonderful (Tom), then it ought to be able to bing-bong you, saying "Suggest you move your boat further up the beach: neap tide today" or "Weather alert: take appropriate action: waves increasing" or similar...Well, if we can have tiny barometers that strap on our wrists and if we can have all this technology in a small device, why not get them all together, if you see what I mean?

    Imagine going to sleep in your bivvy (one "v" or two, anyone?) and hearing in your sub-concious "Gale warning! Gale warning! Small boat advisory -- wake up; move your boat, you stupid snorer..." or something along those colourful lines...

    I hope you didn't read more into my post than I wrote! :) For someone who has already decided to get a gps for kayaking on the ocean, the tide feature is a useful feature. I don't know of any that have weather alerts and no amount of electronics will ever do all your thinking for you! I was camped on a "camp at your own risk" island on the Maine Island Trail once. The campsite was located "Below the dunes, but above the high tide". It was a very calm night. I could hear the water comming closer and closer and thought about packing up the tent and going back out on the water for an hour or so at midnight. Instead, I looked up the actual tide level and the high tide level to figure out exactly how much the tide would rise. The water came right up to low side of the tent! And, that data is now stored on my PC, so I can have a pretty good idea if that island is going to an option next time I'm in the area.

    Some GPS units do have an electronic barometer, 76Csx, for example. Personally, I'd rather have a weather radio.

    Mapping options are a bit overwhelming. Keep in mind that even the lesser priced units have sufficient memory to store enough maps for a month any kayaking use. Memory cards allow you to load every posible map. But, any mapping gps has more than enough memory for a kayak trip. Don't forget to look for some of the older mapping software: I still much prefer the contour lines in original Garmin TOPO map over the shaded relief of the newer maps.

  7. For kayaking, I'd recommend the Garmin 76Cs or the 76Csx or the DeLorme PN40. The 76 is waterproof and floats; has a good basemap, with nav. markers, ship wrecks, tide stations etc. The PN40 may have slightly better mapping. Both units give accurate tidal information so you can know how far to bring your boat up and if your tent will stay dry. The PN40 also gives water current speed from some stations, mostly near/in rivers. The extra accuracy that the 76Csx provides (over the 76Cs) is really not worth much for kayaking.

  8. I use the Garmin 76c. The base map (not blue chart) includes includes most of the navigational aids along the coast. I especially like being able to know the exact tide for the closest tide buoy. The 76c floats (even if it does tend to float away :) ) The waterproofing is good when new, but the battery seals do tend to wear out after a few years.

    There are 2 newer models that I am considering for my next gps. The 76csx has a more accurate chip. This is not useful for boating, but I would enjoy it for Geocaching. The Garmin Colorado has some interesting features, but again, not much additional use for boating.
