Interesting proas

    Here is a junk rigged, shunting Pacific proa, designed and built by the legendary Tim Mann some years ago in the Central Pacific.  I have not been able to find any details of where the halyards, topping lifts etc are secured, but the double sheets are clearly visible. It obviously works and looks good!  I am beginning to think you can get away with fixed masts if you rethink the position of the masthead crane.  Normally it is angled 30 degrees off-centre on the aft side of the mast, on the same side as the sail is rigged.  That won't wok when you reverse the sail, if the mast is fixed.  But if it was 90 degrees to the centreline, or even angled 30 degrees forward, then there will be minimal twist when the sail is reversed.  Time to make a model!  Click on image to view full size.

    I thought I'd start a thread where I (and others) can post interesting proa designs.

    I found some images of the 10m multichine Jester Class proa design by Russell Brown.  One has been built in the Pacific Northwest.  Here is the main hull and a artist's impression.  Click on the images to view full size.

    I'd like about 300mm more beam in the main hull.  And I'd simplify the rig and beam design.

    There are some more drawings in my pro file located in my member albums.  I'll add more as I find them.
