After seeing Dick's post about C Class cats on the rcsailng forum, I was inspired to post the following. Since it got no response, I thought I'd try here in the hopes of getting some discussion started about these rigs. Because of the great speed potential of multihulls, I think winged rigs offer great potential for added performance. I'm surprised there hasn't been more interest in experimenting with them on a multihull platform. Sorry about the replication, but I'm not a good typist & I'm lazy ;-).
Thanks for the wonderful images of winged rigs. Is that a panel of fabric between the main wing & the flap? My personal opinion is that rotating wingmasts in combination with sail fabric will be preferable to solid wings in modeling applications, because of the need to minimize weight & reducing complexity (KISS! principle). Some excellent discussion of wingmast (& solid wing with flap) can be found at: groups.msn.com/LandsailerandIceboatdesignandconstruction/messages.msnw
Of particular interest is Tom Speer's paper about wingmast rigs using the X-Foil modeling program: www.tspeer.com/Wingmasts/teardropPaper.htm
One example of rc multihull applications had been done by Bruce Ewing in NZ radioyachting.com/multihull_photos.htm (scroll down).
Wing rigs offer several advantages where boat speed can exceed windspeed such as multihull & solid surface applications (iceboats & landyachts).
