Of a good strong cuppa and a boat

Regulars will recall the discussion about teamaking some time back. I’m still on the Yorkshire leaf until it runs out but oh, how spectacularly better the process is now – it really does take time.

An essential is the potwarming, so as the kettle approaches boiling, I put hot in the cup and pot, the pot sitting over the cup as you see.

Then water is poured out of the pot and it’s one for each cup of the leaf planned to be taken during the morning and one for the pot.  The boiled goes in and the pot is wrapped in swaddling tea towels and kept wrapped throughout the morning.… More here ...

Sabre rattle shuffle

Well all right, you’d expect the Russian news service to say this:

On Saturday, Russia media reported that during tests the newest Tsirkon 3M22 hypersonic anti-ship missile reached speeds of Mach 8 (eight times faster than the speed of sound).

In March 2016, the Russian Defense Industry began tests of the Tsirkon hypersonic missile, designed to be carried by advanced and modernized warships and submarines, including those of the Husky-class.

Then, it was reported that the missile was expected to reach speeds of Mach 5-6. The missile is expected to have a flying range of 300-400 km.

As distinct from Fat boy Kim, the Russkies might be able to back a certain amount of this up, plus they’re past masters at gluing up with chewing gum things fallen apart.  Hit and miss, many of them hits.

So, let the sabre rattling continue.

The upper pic here is only for a visual reference as to the boat parts and how the type looks in action:

A:  Port netting
B:  Vaka or main hull
C:  Akas or crossbeams
D:  Ama, float, pontoon

There were considerable design problems but think they’re sorted.

The shape of the vaka is as you see in the diagram below and as you can see, it is unstable on its own – it has a waterline length to beam of 1:13.36, which is mighty narrow and fast. The vaka below water level dispalces about 30,000 lbs. The whole vaka, if pressed down to its deck, would displace around 400,000 lbs.

The shape of the ama is a trapezium with a section of 4.5 sq ft.  To give you an idea, the tall side height [B below] is 4.0′ exactly – one plywood sheet across.  It is 41 feet long and the ratio is 1:30.88, making it ultra-narrow.… More here ...

Coming back to this outrigger concept again, let’s dispense with the aesthetics first – you either think it’s the ugliest thing since feminazism or else you see what it’s about.

My concerns with my 41′ 10″ cruiser is that it will transpose from what most of them are – off the beach boats:

… to a genuine blue water cruiser or voyaging canoe if you like:… More here ...

The concept is not one generally used in northern waters:

The southern waters where it’s seen or more specifically the Pacific Ocean can be just as rough and high as the Atlantic, so it puzzles me why it did not take off here – I can only think that narrow inlets and entries between buoys is the reason.… More here ...
