100 Foot Catamaran Container Ship

First run at a 100 foot container cat freighter for the Caribbean.
X-bows, unstayed pipe masts, Maltese type sails, I assume that is best where rigging can’t get in the way of loading and unloading containers.  Open to any other suggestions.
Single skin laminate and stringers in place of hull core.
Crew of 4.
And clearly I need to get kiwi Chris Anderson involved.

  1. p.s. Kurt, agree cross-wise containers best, locking down their corner latches will add to your main crossbeam/bridge torsional strength. Containers could add to individual hull roll stiffness if each mast was linked to the nearby container’s top corner latch while underway…. Chrys.
    P.p.s. Time for you to pop down here – its truly a low stress/$$ overnight flight – time your visit with your Aussi correspondent Tony Coombs …I could do with a little ‘inspiration/encouragement’ eh – you know how it is!

  2. Hi Kurt, been monitoring this since you popped it up – thx for mention – time for my two-cents worth:
    Jorn’s Flettner rotors would need power (maybe considerable – might as well put directly into props) and cylinders may still get in the way in port. How close-winded?
    Frank’s auto rigs would perform well, have pedigree but would interfere in port.
    Maltese: push-button control, beautiful, not close-winded (soft luff ‘luffs’), you’d have to lower the cross-arms and they may still interfere in port.
    My soft wings: no practical demonstration yet (lets ‘talk’)….! Non-rotating ‘D’/tripod masts are hinged (can lower to deck). Once up, sails are ‘bussed’ for single-handed control, each reef-able. Two crew only..?
    I have a ‘high cube HC40’ container outside my boatshed – MAXGROSS 67,200lbs & 9’6″ high – briefly searched but couldn’t find, wondering like Hyong above how small ports without the huge gantry cranes will get these on or off… With my masts down, could back sterns under a bridge with container truck on the bridge side-loading one at a time, re-positioning the boat for each container.
    Any potential client nibbles? Cheers, Kiwi Chrys

  3. Given the many masts and the orientation of the containers vs the fore/aft axis of the ship, how are the containers loaded/unloaded? Large container ships have the long axis parallel to the dock, and are lifted on/off (as I am sure you know) by specialized cranes… For the island service, are you looking at roll on/roll off using mobilizers? Just curious…

    1. yes, customer choice. many advantages. if fore and aft, any rig is in the way. this way the containers can be part of the connective structure.
