-Under those conditions there shouldn't be a problem. The problems on the
original supports were sorted out pretty easily with an extra diagonal strut.
The fuse system worked very well but make sure you have some spare fuses on hand
or you may be tempted to replace it with something else that doesn't give.

low speed.  I do like having the rudder on the LW hull as in the original BD
rudders, I just think it is more aesthetically better looking and gets the
bearing further down for better support.

Can a kick up casset/daggerboard rudder be used so if it does kick up, it is a
simple matter to reset it ? Would either a releasable hold down or elastic cord
hold down be better than a "fuse" type pin that would be more difficult to
replace in a hurry and may get jammed ?

helped with the fairing of Aroha's rudders) and much as I think they satisfy the
requirements, as mentioned by Rudolf, they have balance problems if only partly
down. It is possible to get round this with a curved blade but not easy and I
have other considerations due to the flare on the inside of the hull I wish to
incorporate. I was also considering sliding the rudder in side a barrel to allow
further retraction but the bearings are more expensive to get right. Torlon
balls and careful bearing surfaces are required with the larger diameter. The
kick up system could still be based on a fuse. Money aside this could be a
system that works well. --- In harryproa@yahoogrou ps.com.au, George Kuck

on 360 degree rudders.  All that is needed is a kick up dagger board case.  This
is what is used on the F32. Take a look at the F32 rudder upgrade plans.

date ?  It should be possible to make a kick up case that the dagger board can
go through.  That would allow you to raise dagger rudder part way up for shallow
water and it can still kick up.

may cause a bit of a stir, but should be reasonably cheap and very energy
efficient. I was hoping the admiral was going to retire next March so I could
get back to being a beach bum again but she was give a promotion and decided to
hang in for another year or so. She is in the same line of business as Rob's
wife. We plan to visit Rob when he moves up to Qld and get some sailing in.

sure what what to go for in the rudders. It's is easy to have kick up or
retracting but difficult to get both. I have played around with telescopic
rudders and a shaft that moves up a little way. I have looked at rudders that
kick up by pivoting on the shaft and by the shaft letting go at the bearings.I
am tending to go for the shaft letting go at the bearings and allowing a small
amount of retraction and maybe a sacrificial tip. - In harryproa@yahoogrou
