    Stuart Island currents

    Denham "Islet" is the correct name, my bad. High rocky belt on most its small perimeter. I tented on its south tip, where access is feasible. No sand beach there, but decent short approach at any tide level I believe, with shore zone dropping fast. You can very easily haul your empty boat above...

    Stuart Island currents

    Paddled from Cordero to Calm channel 2 years ago in July against the ebb, skirting Sonora shore, after camping on Denham Is. Back eddies help all the way except at the point jutting out at 50.408644° -125.216771°. But that's a spectacular spot to wait a bit (you see the step of water in front of...

    Skeg box drag

    Mike: I'm with you on the first paragraph - but we have to accept what you say in any case. I suppose/hope(!) you meant “they” instead of the second “you” The tough part of the 2nd paragraph is having the kayak in both cases exactly aligned with the current. Maybe, but my experience lining...

    Skeg box drag

    Regarding the graph you published, I have no clue ... Are these points single data point or averages? There is no error bar attached to them, so it's perplexing. I don't know how many readings they took. The only way would be to actually have a look at the raw data and the full experimental...

    Skeg box drag

    It depends on the number of readings AFAIK. In both cases (with and without rudder, or skeg box), measurements will have the same type of distribution around the average (probably close to a Normal distribution - bell shaped) and the more readings you take, the closer your average should get to...

    Skeg box drag

    Not sure it would bounce around much in a smooth current since the boat+load would have a significant inertia. That's why you'd need to choose a relatively smooth current AND average multiples readings, like 10 at least, over 40 sec. or so. But I have to try to know for sure. Also, any...

    Skeg box drag

    Correction, that should read "You could probably detect a drag differential above ~0.5% with a cheap digital hanging scale (mine gives me 20g steps on a 15kg scale, so ~0.4% measurable variation assuming a ~5kg pull from viscous drag (that's for a hull with barnacles, ie. mine). hmmm... That's...

    Skeg box drag

    Does anybody know if the skeg box creates any measurable amount of drag? "Measurable" ... not sure what you mean... With modern dynamometers, data averaging and careful drag test setup, I would suspect any drag differential due to the skeg box would be very easy to pickup, and it would be...

    Contact towline

    Welcome, John. I have to try it myself as well. I didn't even think about releasing after capsize, but that's obviously a good thing to test as well. Wish I could test it in XChurch. Just noticed your location and it made me smile: I spent a year there in 1987-88 and had basically a non-stop...

    Contact towline

    Thanks John, interesting set-up. I am using something similar but with a small quick-release shackle... that I don't like. A question: as you're contact towing, the system is going to slide on the rescued kayak side of your kayak and the loose end of the line coming out of the highwayman hitch...

    BBQ heat caused a dent in my kayak. HELP.

    I wouldn't even try. The chances of completely ruining your kayak (edit: making it a lot worst) are high if you don't have the right gear and knowledge to repair this stuff. Those thermoformed kayaks have an acrylic finish layer on top of ABS. Good luck producing the temperature and heat...

    Multitool that won't rust in PFD pocket??

    John: If you don't rinse with freshwater after every paddle, then keep the tool inside a couple of strong zip-bags? Doesn't make the thing much bulkier once rolled up. Problem is the tether line if you insist on keeping it. The only SS object I have on my PFD is my knife and even with a shower...

    Blonde Raccoon - Newcastle Is

    I'd bet on small crabs as well. Being a small crab is no piece of cake on these shorelines.

    Even stranger is the fact that clams don't live under rocks or stones.

    Congrats on surviving that terrible Burrard Inlet crossing. The Grebe Islets are fun. I am curious to know what is that new camera with such a poor battery life.

    Anti fog for my camara

    I have never tried a water repellant chemical. I am not 100% sure my window is not coated. So, not keen about smearing it regularly with a glycol ether (RainX is a mixture of 90+%water, isopropyl alcohol, and 2-butoxyethanol [Ref:MSDS]). What I found (with my Olympus TG-5, a small/thin...

    303 on what bits?

    Just tried it (303 Protectant) on my old GPS screen. Works beautifully. Scratches are not affecting screen clarity any longer when direct sun is hitting the unit. Hope it will last a while. Thanks for this tip.

    303 on what bits?

    Dave: I only refered to WGalbraith saying: (...) As the faces on my watch, gps, vhf radio age they are harder to see in bright conditions. The 303 makes them look like new and shed water much better. I would never even think about applying anyting to a camera lens. And you are right, modern...

    303 on what bits?

    Thanks! Will have to try that. I suppose the stuff fills up micro scratches and thereby rebuilts a flat, optically better, surface. But the film left is not really hard nor scratch resistant, is-it? I understand that stuff is mostly an anti-UV agent, so I am currious to see how fast (and badly)...

    Just checked their site. They have many products. Which one do you use for that particular application?
