Subject: Re: [harryproa] Single rudder system G'day,Not sure it can be done, but the rails are very prone to damage if the shunt does not go smoothly and the rudder stops between the beams. No reason why it should, but for an offshore boat, the rails would need to be pretty heavy.The lines look good in theory, and are only loaded in tension so should be very strong and forgiving of errors. I may need some guides to get the rudder assembly under the beams and into the brackets, but this is a small price to pay. Will post some photos/take you for a sail when it is done.regards,Rob----- Original Message -----From: Doug HainesSent: Saturday, October 14, 2006 7:03 AMSubject: Re: [harryproa] Single rudder systemI don't see how you do it without rails. G'day,First, congratulations on making it to Mandurah. Doubly so, considering the state of the windsurfer rigs.Using the tiller extension is a good way to move the rudder as long as you can pull it directly. Towards the end it becomes a leverage job and gets difficult. The rope is easier. Takes a few seconds to pull a light load 2 metres. The longest part is shunting the sail.Where do you want the pin? Once the rudder is in place, water pressure keeps it there. The rails are past the beams because of the support set up I had. They and the rails are for the chop next week to be replaced with brackets directly under the beams and ropes instead of the rails.regards,Rob----- Original Message -----From: Doug HainesSent: Friday, October 13, 2006 2:10 PMSubject: [harryproa] Single rudder systemRob,I was just looking at a pic of whatever your boat is called - I guess it is THE Elementarry - anyway how about using the pole/tiller to shift/slide the rudder up the other end? I noticed a rope and pulley -that would take a litlle bit longer would it not?If the rails are slippery enough.Also how about a pin with a spring that you pull out to rlease the rudder, that is using a ropeto the helm station.Are these anyhing you were thinking of improving.?Also noticed you extended the rails out past the beams - I was calling past your house a week ago but you were not in.Doug

Nice ENE to head South with a low swell, and offshore winds was a
good run. Probably averaged above 5 knots most of the way. The
Easterly dropped away about 10am and I fell a sleep for an hour
waiting for the SWly seabreeze to come in. The breeze seemed a bit
more WSW so managed to stay on course for the Mandurah entrance which
is straight South. I got to the low wooden bridge in town and thought
about sailing under but chickened out and pullled the two winsurfer
masts out and rudder swished my way under and into Soldiers cove
withe the sails up agaain.

without going up and downover them, comfortable enough on the deck,
rudder very light if raked forward slighty( though this stops the
rudder from being used as ascullibng oar, it needs to be angled
backwards), sheet controls work good, shunting is fun but at the
moment takes time to put the rudder up and then the other one down
and my sails aren't getting away fast enough to give the rudder
enough effect so makinng the shunting a bit of work expect this to
improve with the masts done.

the water under the beams and through the net, you can see all of the
rudder going through the water, and watch the entry and exit of
especially the LW hull. Getting on from wlking out in the water is
easy and the wide beam and high buoyancy hulls make a stable platform
for sailling and staying on board.
