  1. There's one other source you should always search for a question like this...right here. https://www.nspn.org/forum/topic/7814-tides-and-currents/
  2. Ah, one of my favorite tomes. Tides and Currents in Portsmouth Harbor, A. J. Hoskinson, US Coast and Geodetic Survey Special Publication No. 150, 1929 https://babel.hathitrust.org/cgi/pt?id=uc1.$b72168;view=1up;seq=5 Should be at https://library.noaa.gov/Collections/Digital-Collections/USCGS-Special-Pubs , but the links from there aren't working now. There are similar pubs for other areas, all about as old. Thanks for finding those tide tables. Hadn't found that before, and it's just what I need for something right now...
  3. I am. Think of it as an independent study project for the jobless.
  4. Waves, tides, and currents: the kayaking environment Sunday, February 17 - 11 am to mid afternoon - REI Community Room, Reading MA We’ll learn the physical causes of waves, tides, and currents, and might find out: Why do waves come in sets? Why are the waves on some beaches always dumping? Rip current…friend or foe? Why is the water so rough around headlands? Why does a 12 second wave have 4x the energy of a 6 second wave? Why is the tide 50 minutes later each day? Why is there a bigger and a smaller tide each day…sometimes? Why are the tides so big in the Bay of Fundy? Lots of drawings and graphs, few equations (all avoidable). After the presentation we’ll have an open discussion of strategies to deal with waves and currents as a kayaker, where to get predictions, and rules for interpolation. This event is open to paid club members only. Please RSVP on the club calendar here.

  6. Not me. Shoulder bad. Bad shoulder! Bad! Sit! Stay!
  7. Jim, More discussion on this in a previous topic, Don't forget to add a scale and lat/long. I got tired of paying Staples for lamination (already have a 11x17 printer), and got a cheap Amazon Basics laminator, about $30. Works great. A pack of 100 laminating sheets costs more than the gadget, but maybe people could get together and split a pack.
  8. Keith, In theory it should be, however... ACA is still working out some of its membership practices, and we're still working out how to deal with them. I don't see you listed with ACA as a member of NSPN as a PAC. A paper waiver (with your ACA member number) would help, at least for now. Thanks, Mike
  9. I have spots for the next two sessions (19 and 27 Jan) if anyone would like them.
  10. My kayak's in the workout room too...but that's because it's also the winter gelcoat repair center. It does help to have it there. A basement dehumidifier helps gear dry faster. Electric motors with brushes that make sparks create ozone, which is bad for latex. Not many motors like that around now, though.
  11. Haverhill HS. See top of Rob’s first post.
  12. Heck, I could launch at noon and be back by 2.
  13. Masconomo could be nice. Lots of shelter for a relaxed paddle in and out of the harbor. Just got back from walking West Beach. Berms of seaweed in cove, but clear past the rocks, as usual in the winter. The west part of the parking lot is closed off with barriers, but one could haul a kayak on a cart through them for easy access to the clean part of the beach.
  14. Not much worse than the rest of the body...
  15. I've been quiet, but...any of the above might work.
  16. Probably not. People here seem to prefer polar regions, especially in lousy weather.
  17. Hull-a-ports are J hooks, not Hullavators. Hold the kayak at the cockpit. Put the bow in the front hook, and slide the kayak forward on the hook. Swing the boat up onto the rear hook, letting it pivot on the front hook.
  18. So proud to be there to be a part of this. Well earned, Rob.
  19. Maine Sea Grant publication: http://seagrant.umaine.edu/files/Public Shoreline Access in Maine.pdf More at http://accessingthemainecoast.com/ Massachusetts https://www.mass.gov/service-details/public-rights-along-the-shoreline
  20. Confirmation of the obvious. Congratulations!
  21. I’ll paddle but I won’t mourn. Must have strudel.
  22. I’ll be there. We’ve had a good bunch every week.
  23. Pablo, you must be spying on me. This is what I've been working on this rainy day. Get .pdf raster chart from NOAA at address Ed gives above. Open in an image editor...I'm using Pixelmator on a Mac. Select the area of the chart you want (rectangular selection; can rotate for a NE/SW section of coast, for example), and duplicate this selection onto a new layer. Select the scale, duplicate it onto a new layer, and drag it to an uninteresting area on the chart selection. Repeat for a compass rose if you like. Repeat for lat/long borders, but shift/drag them so they stay aligned. Add notes if you like. (might want to save your Pixelmator file here) Crop to remove excess canvas area around the chart selection. Save as .pdf Print and laminate, or send .pdf to Staples or wherever and let them do it. I'd welcome being told there's a better way.
