    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

    [​IMG]
    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 ?

    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!

    Best Regards

    You might be interested in the proprietary demounting rig designed by Gemini Catamarans for their Trimaran, the Telstar 28.
