RG65 - Mast aft - with foils

Not sure what to call this, and I'm not sure that it makes any sense, but it should be fun to test.

RG65 - narrow - Mast aft double jib sail, T- foils on keel, and rudder and stubby dss-like foils.

This is why I love the RG-65 ! Wish that we had more guys like you throwing stuff out there to see what works. Can't wait to see the video on this one !
I am getting close on my latest version of my chined hull. Moved everything aft and added more volume forward and aft and slimmed her down a bit. faired in the keel slot tonight and cleaned up the rudder. I have mounted the sail winch drum, but have to figure out what works best. I have always used a servo with an arm, so not really sure what will work best....thoughts anyone. I am using a swing rig.
All the best to your creation rcmm

Thanks Bob. I agree with your thoughts on the RG65 class. Although my boat isn't class legal, it is a good size for trying ideas quickly and at minimal cost.

Your idea seems to be evolving nicely. It would be good to see some footage of your new boat on the water.

Planning to test without rc and electronics to begin with (kayaking alongside), so video will be a bit difficult for a while. Will post when I can.

BTW, there is a 16 page thread over on RCsailing.net forums on Delta rigs here.

Here's a video from Claudio's test boat:

Yes, I first found out about this type of sail from Claudio's work. I spent some time developing rigid analogues of these sails:

A mast aft wing sail on an RG65 rc sailboat (5 min 13 sec)


Canting mast aft wing sail on a rc RG65 sailboat (3 min 23 sec)


A mast aft double wing sail on an RG65 rc sailboat (2 min 40 sec)


The sail on this boat is a bit different to Claudio's as it is in two parts with a slot.
