Re: Little Egret: an Egret-style day sailer
The painting is certainly bringing out the crisp lines of this design John and your choice of colours very "tropical".Lovely!
If it were I fiddling around with the rudder, I would proceed as follows:
1) Copy precise shape of rudder as drawn by the designer.
2) Secure the rudder post to the rudder as if it had to last a life-time.No fussy-wussy temp stuff.
3) Only use one end plate on the bottom of the blade, as the hull above it will take care of what is rushing off the top of the rudder. Despite the light floating water-line on the drawings, she will probably settle a bit more by the stern once you are on board sitting comfy by the tiller. I know the stern is rather fine and the bottom of the boat will only provide end plate effect within a narrow quadrant but keep in mind that a rudder soon loses its' steering effect and begins acting like a mild brake beyond a certain angle(can't recall the angle). With a split rig like you have, you'll be able to dial in perfect helm balance and literally steer her by sails alone.
4) Sail the blazes out of her,ie;use frequently,discover her foibles and use them to best advantage.
5) Take lots of pictures sailing.
6) Let me buy the first round if we ever meet!
Do it,do it,do it,do it,do it,do it,do it,now!
This boat was built with ten thumbs.No fingers were harmed in anyway.
