    Something I've been playing with. I hate using drawing programs. If I know I want a line 14.42* of so long, trying to get it exactly correct with a mouse drives me bat@#$% crazy. So I wrote a little static webpage with a program in it do draw the lines I wanted. It's design to fit charts generated at 25000:1 for 8.5"x11" paper in portrait mode from https://devgis.charttools.noaa.gov/pod/. It's an overlay of a three mag north lines separated by .5 nautical miles. (I need to double check the scale one more time but I think it's very close.) The intent is that you either find a utility that can overlay an image on a .pdf or use the luddite solution of running a piece of paper through the printer twice. Print the chart and the print this page on the same paper. This was my lunch time project and I gotta get back to real life now. But I'm going to look it over one more time and if everything looks good, do another one for landscape mode. Disclaimer: it renders correctly for me in Chrome on my Mac. On a different machine and/or with a different browser, it might scale differently. The angle of the lines will likely remain correct but there's no guarantee on exact position of the lins. If you try to use this, use the attached .html file, not the preview image. What's in the file -- <!DOCTYPE html> <html> <body> <canvas id="myCanvas" width="850" height="1100" style="border:0px solid #d3d3d3;"> Your browser does not support the canvas element. </canvas> <script> // SET THIS BASED ON LOCATION -- magentic declination in degrees. const deg = -14.42; const canvas = document.getElementById("myCanvas"); const ctx = canvas.getContext("2d"); const rad = deg / 180 * Math.PI; const lineTop = 110; // Based on the canvas height and desired margin. const lineBot = 950; // Based on the canvs height and desired margin. const centerX = 425; // Based on center of the canvas width. const lineYLen = lineBot-lineTop; const lineSpacing = 151; // Based on chart scale, how far apart parallel lines appear, determined emperically. const intervalX = lineSpacing / Math.cos(rad); const firstLineX = centerX - intervalX; const lastLineX = centerX + intervalX; for (let lineX = firstLineX; lineX<=lastLineX; lineX=lineX+intervalX) { const lineTopX = lineX + lineYLen * Math.sin(rad) / 2; const lineBotX = lineX - lineYLen * Math.sin(rad) / 2; ctx.moveTo(lineBotX,lineBot); ctx.lineTo(lineTopX,lineTop); ctx.stroke(); } </script> </body> </html> linesOverlayPortrait.html

    Taking another look at Mark's pic above, I see he was able to overcome the issue I had with the rear block not being far enough back by using the tie the block to the boat first method. I swapped out the Camry with my son until October so the issue it moot now. If I did use the technique I showed above, another thing I could have tried it putting the foam block on one of my Thule bars and resting it directly on the roof (with a small bit of foam to prevent scratching). That would direct all the force to the sides of the roof. That probably would have worked. But again, now it's moot. -K

    I have the old square bars without the ratchet grove on the bottom, won't fit the new feet. It would have been about $600 for new feet and bars for my Camry. I used foam blocks and about eight tie-down straps until I had a chance to swap my kid the Camry for the Venza for the summer. Yeah, still hijacking the thread; back to EVs... I still don't drive enough to make it worthwhile buying an EV at the present time. I've considered keeping the venza for AWD in snow, trips to the dump, long trips with boats and lots of gear; and then getting something super efficient like a Bolt for day-to-day driving. The killer is there is almost no break for insuring a second vehicle. It'd add $600-800/year to add the second vehicle to the policy which would be more than I'd save on fuel. To lose the Venza and buy an electric with equivalent capabilities would be like $60K. I'm still wondering if there will be a breakthrough in eFuels and we'll eventually have renewable carbon neutral fuel. -K

    Being that I already printed the two pages I needed, I used the luddite tools of protractor and sharpie to add a couple 15* lines. What's very coincidental is on a 25000 chart on 8.5x11" paper, the 15* lines line up within a whisker of where the 1 minute latitude lines meet the edge of the image. So close that the next time I print something at this res, I don't think I'll even measure, just draw lines between those points.

    Thanks Joe. I think you covered some of this stuff in the online sessions. Tough to remember everything I try to learn last winter. We're planning to paddle directly along the shore from Broad Cove to Mackworth island on Sunday. So it isnt a must have this week. I just want to keep learning so that I can get it when I need it. -Ken

    I'm here -- https://devgis.charttools.noaa.gov/pod/ working on generating some charts. I'm getting the areas on want on charts and generating pdfs with the export function. I have the compass rose option turned on but there isn't a way to get a rose in the extent I generated. I'm wondering if position a rose on the chart is a feature that is not implemented yet. Attached is a screen shot of the application showing the extent I want to generate. There's a partial rose in the picture but it's obviously not going to be in the extent. Is the only solution to hack the chart after it's generated and copy and paste the rose into the image?

    I did get a boat on blocks on the Camry. I didn't need to tie the blocks to the boat first as I have a suction-cup roller thingie I can put on the back window. Then I can roll the boat up. Effectively I built a soft rack on the car. It's acceptable for running down to the local river, only a few miles, for some fitness paddling. I don't know that I'd do a trip with it. The front block is right between the top of the windshield and the moonroof and the roof is very solid there. But the rear foam block is another story. You can see the angle of the rear window frame tapering down so I can't get the rear block back any further. That spot on the roof is quite boingy. If I could get it back 6-8" more, it'd be in a spot where the roof is reinforced. But where it is, the roof is just thin sheet metal and it bends a lot. If I was going for a long trip, I'd have to put something solid across the width of the car so the sides take the load. It's somewhat moot now, tomorrow I'm swapping cars with my son and will have the Venza back for the summer. It has a original-equipment roof rack. -Ken

    Do you have an expected length for this paddle? I may or may not be free but if I am and it's within my distance limit, I'd be up for it. -Ken

    Video didn't play for me on Chrome on MacOS; did play on FireFox on MacOS. -K

    I'm way too old to give a @#$% if people point at me. I probably won't be going on rainy days. So, I guess it's viable. I do suspect it would be much harder to load. I might use the method where the blocks are tied to the kayak first and then lift it up. -K

    The car with the roof rack is with my son at college and I don't really want to spend $600 on a roof rack for my 2012 Camry for a few spring paddles before he gets home in May. I have foam blocks like the ones below and in the video linked below. (Not the whole kit as I have close to a dozen buckle straps already.) Any thoughts on reliability of the foam block method, similar to what is shown in the video below? I don't so much worry about a local five mile drive at 30MPH to the river for a quick exercise session. I'm worried it might be dodgy on the highway. One thing I don't like about the video is there is a single strap over the boat. I think it might be better to have a strap running over the boat as each block. Have them loop under the block strap, run over the boat, and when through the black strap on the other side. Then add one strap over the whole boat and through the windows like in the video for an insurance strap. Also, there are no tie-down points underneath my car so I use those slugs with the loop that fit under the hood. My boats are about 17.5' so the bow is almost to the front of the car. https://www.youtube.com/watch?v=kOlFSKffGJk

    Thanks, there's also treatment of that effect in Tristan Gooley's book "How to Read Water: Clues and Patterns from Puddles to the Sea."

    I see from the map that there is virtually infinite fetch to the South and East so depending on wind, I would think it could be bouncy with the wind from those directions. Magic Seadweed has forecasts for both those beeches which could be useful. https://magicseaweed.com/Short-Sands-Surf-Report/366/ https://magicseaweed.com/Long-Sands-Surf-Report/367/

    A friend who is an exerpienced ocean swimmer, has done the Portland->Peaks Island swim many many times, did Alcatraz->SF last year, is thinking of doing the Nubble Light swim in York, ME. She might want me to paddle as a support kayak. I'm curious if anyone here had paddles in that area and can comment on the conditions, which of course would depend on the weather at the time. https://www.nubblelightchallenge.org/event-details

    Whenever I see fledgling ducks and geese, I wonder how come it took so long for scientiest to figure out that birds are dinosaurs.

    I actually still own a Morey-branded board. Left it at my bro's house on the cape. Haven't used it in a decade. -Ken

    I always consider the B&M Bean factory on Casco Bay on the north side of Portland ME to be a landmark. I saw on the news this AM that they are tearing it down and replacing it with a tech campus. The B&M Bean factory was featured in this segment of on the History Channel.

    I bought me Cetus at Newbury in spring of 2020. I was planning on adding a keelstrip after I used it for a season or two. I was going to bring it back to Newbury. I was thinking of doing it at the end of this season. Do you think they'll still have people that know how to do good work on glass boats? -Ken

    What you could do is show up at a few group paddles and politely ask to try on everyone's helmet. Then go buy whichever one fits the best.

    Any issues regarding deteriorating weather forecast?

    Reread and see it ends at 12:00 PM. That's cool. -Ken

    I did the ACA thing. I think I registered for the Event. Is there a way to check confirmation? Any chance of changes due to weather? I suspect staying in the harbor will be a okay with respect to avoiding excessive waves, might still be just a little wet out. -Ken

    Not totally applicable to kayaking but I just found this two GIS familities that are fun to play with. The latter may have some info apropos to kayaking. http://maps.massgis.state.ma.us/map_ol/oliver.php http://maps.massgis.state.ma.us/map_ol/moris.php

    Thanks for the response. I did paddle there in an NSPN level-2 paddle (6/23/2019) that Rob led and liked the location. I recalled there was plenty of parking and I don't recall any place to pay but I guess it's changed. -Ken

    Anyone know that status of the launch and parking at 500 Ocean Blvd, Rye NH? A friend of mine in the Portland ME area just go into kayaking and I thought it might be a nice place to meet halfway for a paddle. I don't know what the deal with with restrictions and parking and whether it is open now. -Ken
