Rob,
Sort of thinking about next boat (harry/rapscallion sort of extended lw hull),
And if using rudders like harriette, I know you gave me some instructions on not using balsa core because the shaft is taking diffrent loads to the other full blade shape ones.
Plus carbon went on the front and back sides as well as the sides all was wrapped round db. The blade is not there to take twisting into the case..
Could you remind me about that because I procured some pootential balsa shaft pieces and was not liking a solid wooden core like is on harriette. Or is a hollow one better?
Just thinking ahead, now stuffs finished off.
Also - this thing with the two easy rigs (schooner), it seems you could fiot two easy rigs, 3m main foot and 2m jib foot, or some combination adding to less than 5.3m total which is the clearence from one beam/mast to the other. Apart from the extra sail area/ lower effort, Any guesses as to how the sail interaction would work?
I would try it if it wasn't such a big decision regarding building work just to test out a theory.
In fact I've just talked myself out of it because of the extra sailing work during shunting two masts instead of one.
Simplifies things I think.
I tend to think the ww hull should be finer L/B ratio, it is double the lw ratio!
Unless it lifts a lttle ( would it lift a small amount under average sailing conditions?)
, then you get same legth and less beam in the water. Though the flat bottom floorless ww hull design would negate that advantage.

To whom it may concern,
Just wondering if ever get that far if it (painted bright yellow, with a motor pod), is still in Cairns as read in website report. Ans is it sailing?

Um, because it's no use *me* downsizing the photos because they've already had to come through my ISP and into my email client! While some
online systems and local clients, especially those who monitor whether it's a mobile device or not that is asking, will check with you whether you want to download large attachments, most won't. Irfanview has been
around for, IIRC, 8-10 years and it my favorite for downsizing *my* photos (Lanczos downsampling, little sharpening, jpeg 50-70 depending on the detail). Takes a 7MB file down to 50KB and is quite good for web
viewing.
Sorry, no proa or Harry content. Oh, except for 'arrying Doug on image size ;-)
