The last major decision

Referring to design decisions on Das Boot. The stations can’t be altered, as they are based on the walls between cabins, they give four masts and some form of headsail[s]. That’s been so for a long while now.

What has not been decided is the form of the sail between those masts and the variants which can be used on larger boats include these three:

Lugsail

This is pretty well what I’d decided on and its advantages are many – simple, one halyard raise, forms a natural curve, is balanced either side of mast, eases pressure on sheets, that’s it.  Was used as the aft sail on sailing ships for centuries.

Downside is that, as a triangle goes forward of the mast, it interferes, on the foremast, with the staysail/jib.  There is a way around it and that is to place the jib further out but that lengthens the boat.

Also, given that a wire connects the mast ahead and behind, so that the sidestays can go out 90 degrees and so the boom can then swing out more widely, there is a finite area under that wire and the lugsail has the least of these three.… More here ...

Der Trimaran

Excuse, please, the wonky iPad shot of my clipboard taken in last evening’s twilight but this is what I’m working off – probably by the time you get to read this today:

Main hull

What I still have downstairs at this point is a monohull of the overall beam shown in the pic [6’10”].  The new central hull sides are being built within that hull [thereby cheating the weather by being enclosed, later the outer will be stripped away and the wood used on the pontoons.… More here ...

Das Boot – impossible dream?

And to immediately answer my question – no, not impossible. Just have to be ultra-careful but I have now come to the point of irrevocable decision this weekend.

As I have a blog here, a ready-made forum, I invite informed comment and hard-hitting questions, the type Ivan used to ask.  I’ll meet those and see how it impinges.

You see, on Tuesday I must decide which way to go – the main hull is now cut to size and so the remaining issue is which of two configurations for the rest.  I’ll divide these into buildability, liveability and safety on the canal, liveability and safety at sea.

Das Boot

The pictures are not dissimilar but there are key differences to mine.

There are aspects I can’t alter with the boat and they’ve always been – four or five mast points [with or without jib] which are the compartment walls as well as the points for beams if multihulled.

I deliberately made it so that whichever configuration was used, there was a bulkhead up front, then a 6’3″ fore-cabin, a 2’3″ space with hatch above for hanging space/storage, then another cabin or salon the same size, then another hatch/hanging/storage space, then another cabin, then a solid wall, then the long raised area at the stern for sailing and galley/loo.… More here ...

Ford Crown Victoria

File under “well I never”. Haiku sends details of the Ford Crown Victoria, a car I’ve never heard of and I wonder why – probably the years. Geelong FC is sponsored by Ford, I spent many years in Victoria – never heard of this though:

Well I never:

The Ford Crown Victoria Police Interceptor (colloquially referred to simply as the CVPIP71, or Crown Vic) is a four-door body-on-framesedan that was manufactured by Ford from 1992 1/2 to 2011. It is the law enforcement version of the Ford Crown Victoria. From 1997 to 2011, the Ford Crown Victoria Police Interceptor was the most widely used automobile in law enforcement operations in the United States and Canada. They were also used for this purpose on a more limited scale in other countries.
