Hi there,
Been for a few more little sails on SideCar down in Mandurah, and what
with the go on Rob's last week I think I follow the accepted findings,
such as written in harryproa web site articles.
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.
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).
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?
Doug
