mast and rigging setups

Holland has standing mast routes were highway bridges open for the upper nautical class
striking a mast, if possible, is so much work most bigger boats leave the mast up powering inland

all that is ok but long as there are more than keel stepped unstayed rotating masts
a smart folding, or as in this picture creasing mast may make live better on society, crew and boat


looked for: hinging, elbow, telecopic or what do you have masts and this one as example
yet on a folding tri with the right rigging how big the downsides?

other alternative systems ?

 

Well for a start I can tell ya that mobile tower crane aint gunna float. lol

Something like this?

Many of the European boats we see here tend to have tabernacle arrangements and sheerlegs for lowering their masts. Usualy by some arrangement of the anchor winch but on some vessels a seperate winch just aft of the main mast.

Steel masts lend themselves well to hinged sections.

Have a good one

 

Yes, thanks for that bowsprit / winch combi, that’s the sort of variation rigging I’m looking for
Maybe I’ve been looking to long at a giant crane getting the yachts ashore brainstorming

found round 1700 they even sometimes placed a small mast with sail on the bowsprit
but good or bad, I’m searching history to ideas and wikipedia doesnt have it all
Gareth attended me to the transition rig site, love the name but how to stay, reef or furl etc

I am drawing davids or booms getting a aft bipod mast up in a power/sail cat design
could be with sternsprit but also like to use davids / booms, hmm... got to know what i'm drawing

do like the lateen: http://www.boatdesign.net/forums/showthread.php?t=14674
Specially if a bipod keeps the sail free changing course (but ad drag)
than again cant you think of it somehow as a windsurf rig

maybe i’m only checking evolution did not miss something and did a search on “mast” types
now remember some more sites I want to check again
just see hansje's great work in the gallery with fishing booms
I’ll be back

 

Howdy,

Hinged and telescopic rigs exist!

Gaff and Lug rigs which can be made to perform quite nicely using modern approaches to rigging and sparring as well as using more modern distribution of area in the sails.

Interestingly the more modern distribution of area is the same as most boats before the advent of genoa jibs!

just read bout the gunther top
and your so right, that crane is a gaff rig like most boats i sailed on
see what i can find on modern approaches

good reviews indeed, did not see strange rigging but the use as powerboat looks pretty good

here another transverse double master
