edit.. all the pictures in this thread have probably gone away so I put them all on this page
http://analogengineering.com/sail/hobie ... auler.htmlIf you have been around this forum for a while, there have been a few boom experiments, here is one that I found from a search
https://www.youtube.com/watch?v=CVrLIBqztscIm not sure I think there will be much improvement using a boom for reaching.. but maybe some small incremental amount. My reason for messing with this is that buddies are getting spinnakers and the lake I sail on has a lot of downwind sailing so what drove this is more about down wind sailing.
So the boom for down wind would act more like a whisker pole allowing the main sail to show a lot of area when heading down wind. I have been messing with different versions of barber haulers so had the pulleys at the ama and the cleats for the barber hauler already mounted on the hull. I used this again as a sort of boom vang.
The boom is made from an old top section of a windsurfing mast. I have not tried it yet.. but it looks promising
First picture shows the windsurfing top section mast and all the compents noted.
Note that the barber hauler attached near the boom end is a continuous loop and will act somewhat like a boom vang.
The down side (and I still have not tested it yet), only one person sitting in the back seat can use the boat with the boom.. unless the front person REALLY ducks..
Note.. no new holes were drilled in anything doing this (about the first time that has happened LOL).
Block attached to the outside of the Ama
Dont know how this will work yet but I wanted an adjustable outhaul. If I need to reef the sail, the outhaul is easy to disconnect and the boom gets set over to one side - not used when the sail is reefed.
I still want to be able to reef the sail so this is how it will look when the boom is still attached at the front but held over to the side by the barber hauler lines
The tapped holes to mount the plate for the rotating boom front end were already on the front brace so no new holes
Boom is detached by pushing on the pin and pulling it out. I will bungie this in place later
Boom stored in the paddle slot - held in place in the rear by the barber hauler lines
The amas can be folded with the boom in any of the positions it can be placed
