"Performance and ease of sailing improved markedly. Top speed was 18.5 knots and it points as high as the Tornados, although we it is not as quick upwind. "
First off, I was enjoying having two nice hobies coming by when I noticed that I had veered towards the channel marker. Steering either way didn't do much and the pointy green starboard marker made a nice foot long rip half way up the forward sail. Nevermind.
I've realised that some of Rob's comments apply to his own plans for sailing and they differ a little from my plans. I've been seeing what I need to cruise along the coast. Maneouvrability is a let down. The basis of speed and long thin hull is firmly fixed, and all I can
see to steer better is moving rudders aft. I appreciate now that perhaps Rob was looking ahead to his transpac boat and long distance racing. It seemed easier to me to build at the time so I copied his beam mounted rudder idea. Now I am wondering how to get them back a bit.
There is no easy way to move them aft. You will need to get inside the lee hull to strengthen it up. My boat steers well with a rudder on the beam, except at low speeds, when it tends to go sideways faster then it turns. However, at low speeds, if anything is in the way. reverse the sails and go backwards for another shot. OR, better, move your weight forward, which gives the boat something to turn around.
As for the schooner rig, well it seems sensible, lowering centre of effort and transfering loads directly at the beams. Trying to sail it on your own though is a diffrent matter. Now Rob (and Mark),
report speed INCREASING USING ONE SAIL. (wHAT IS A hARRYPROA WITH ONE MAST OR SAIL? aA UNITARY). Watching both sails is confusing, especially at high speeds, tight navigation, tired etc. I would attribute some speed gain to accurate angling. Again I'm thinking about myself and maybe a racing pair could work two sails (comments Rob?, eg. photos shown at Coffs Harb).
Unitarry is good. Speed does not increase with one sail which is half the size of two sails, except in big breeze. Two sails are great, but hard work solo, particularly if the boat is not set up for it..
Good note, is that reducing stiffness in battens improved sail shape today. Rudder blades also sanded/polished smoothe seem to go better and avoid seaweed snags better, must be slipping off to the side.
Question - what is your sail luff and foot lengths going to be
Rob? And is the rope better than slugs for sail shape?
The foot will stay at 2m, not sure how much higher. The rope is theoretiucally better (seals the gap), but for cruising, slugs are much superior as the sail can be left on the boom and does not blow around when lowered.
Hope to be down for the first multiple harryproa sailing event this weekend.
regards,
Rob

I'd be interested in seeing the same area in the cat rig with a taller mast/longer foot - is that feasible? Is there a downside? David ... Received: Fri, 06...
Hi David, I find that my aft sail will turn the boat around up in to the wind and needs the fore sail to balance it out. Therefore I hope to move the area...
G'day, Downsides are it is harder to move around, higher centre of effort (not a down side in light air) and harder to right after a capsize. regards, Rob ... ...
I read today about report 5 elementarry i think - sheet in forward sail after shunting, bear away, and you're sailing. This is what I find too, especially as...
I could live with that if the performance was better. What happens if you scale it up to Harry or Visionarry size? What about balance? PS Took the family to...

G'day, Not sure, but there is no reason why it shouldn't work, although the ability to weight shift on Harry and Elementarry is not to be forgotten. Once the...
