Re: taran vs inuk ultra 20?

I was starting to make plans for a long tour on the West of Scotland before covid hit. The Taran of course was designed as a fast expedition boat so it's got to be on the shortlist. Although the 18ft could sprint faster, the 16ft might be more efficient at lower speeds as well as more manoeuverable....

The bothy rats are big and fat.
As big as dogs. As big as cats.
They feast on deer. They feast on sheep.
And bothiers when they fall asleep.

Re: Peanmeanach

The best way to describe a bothy is to think of a posh hotel. Then take out all the beds. And all the furniture - except for a few DIY wooden benches. Remove the bar and the toilets. Rip up all the carpets. Disconnect gas, water and electricity. Add some mice. That's a bothy. You still have a roof a...

Re: Nansen in the Arctic

Still trying to get my head around the log shelter.

"It's getting dark: let's spend the night in the bothy." OK, I can comprehend that.

"It's getting dark (as the polar night descends). Let's spend the next several months in a hole in the ground."

Tough cookies.

Re: Bike towing a sea kayak

I don't like the look of that "dumb stick" attached to the seat post: there's a lot of leverage on the attachment point. A rear pannier rack would probably give you a more solid platform on which to mount a stick.

Agree about centering the trolley - that will take a lot of force off the stick.

Re: Home made paddle floats - any tips

A fat mountain bike inner tube & CO2 cartridge pump might work if this would provide enough buoyancy? Just figure out a way to wrap it round the paddle, press the button and hey presto! The CO2 pump could be screwed onto the valve ready to go.

Doubles as an emergency lifebelt.

Re: Cag lining issues...

Silicone bath sealant might work. I've used it to seal seams on tents and jackets.

Try a tiny spot first to see if it will stick to the waterproof lining.

It's a bit thick straight out the tube. You can dilute it with white spirit - use the odour-free kind ;) - and paint it on with a brush.

Re: Energy drinks

I'm not 100% sure but I think eating any kind of food triggers this process.

It's a red line I wouldn't want to go near though, for safety reasons, unless there's an easy exit to shore.

Apart from protection against excessive discharge (mentioned above) the batteries would need individual charging circuits that detect when charging is complete, as they wouldn't all reach full charge at exactly the same time and overcharging can cause them to explode.

Re: Charging a vhf radio from a lithium power bank

It should also be possible to DIY a 12V power supply with a bunch of 18650 batteries connected to a ready-made step up converter like this.

That's more or less what you'll find inside a standard powerbank: a bunch of 18650's and a circuit board.

Re: Rudder and skeg on the same boat

By "unbalanced" I just mean difficult or impossible to hold a course in strong winds. Rudder & skeg influence weather/lee cocking. I suspect that one might work better than the other in tough conditions but you wouldn't want to use both together. I don't really know for sure.
