I'm curious if anyone has any experience with an outboard stern
mounted emergency/alternate rudder on the Albin Vega. I've seen some
pictures of Vegas with a stern mounted rudder but can't seem to find a
design or comments about the modification/addition. I have come
across some literature with mathematical equations etc. to design a
proper one, but I figure I'd check with you folks first before I get
started on straining my brain! If someone has already addressed this
subject in this group, please excuse me.

Thanks!

Hello Bobby,

Jan van Craaikamp, owner of V973 did add an extra rudder to his Vega, he
documented this on the following website:
The text is in dutch but the pictures and drawing may be helpful.

Also in the Netherlands there is http://vegaboatsupplies.oppermans.net/ he
builds and sells this wooden extra rudder for the Vega on request.

Please let me know if you want me to translate some Dutch text to English.

Best regards, BregtOn Wed, Sep 10, 2008 at 12:02 PM, lindsaystaringatthesun

Aloha Bregt,

Gosh, I must have strained my brain just thinking about straining my
brain! I thought I replied to your very helpful email, but looking at
the posts this evening I must have neglected to press "send"! Anyhow,
I really appreciate the direction you pointed me in. I found the
photos and drawing provided by Jan van Craaikamp to be an excellent
place for me to begin. Would you know if in his accompanying
literature there is made mention of what cord and foil specifications
he incorporated and how he derived them?

Much Thanks!
Bobby

Why mount a rudder on the stern, where it is far more exposed to damage from a hard docking?

The Singlehanded Sailing Society requires the participants in
some of their races to have an emergency rudder on board and
demonstrate that it works. It's purpose is to get the boat back to
harbor should the primary rudder fail, not necessarily maneuver about
the marina. They have examples of various solutions at their website.
Singlehanded Sailing Society
At least one of the boats uses a simple pintle and gudgeon
system to hang the rudder off the stern, but the force, particularly
on the lower gudgeon, must be very considerable and the transom may
not be able support it without making some modifications. Perhaps
using standard heavy duty pintles but making your own gudgeons with a
much larger bearing surface would be sufficient. Installing the
rudder at sea would also be difficult because the entire blade needs
to be submerged before the pintles engage the gudgeons. Lining up the
three pintles as the boat rolls in one direction and the rudder in
another might be frustrating.

Another solution may be to follow the example of sailing skiffs which
use a cassette system, a slot or channel molded onto or bolted onto
the stern into which the rudder shaft is inserted. Because the entire
channel is supported as a unit, instead of each gudgeon individually,
the system should be stronger. Also, because the blade extends below
the lower end of the shaft, only a small part of it need be submerged
before the shaft itself enters the channel at deck level.

The SSS has just completed their 2008 TransPac race, S. F. to Hawaii.
All boats finished though Sparky finished under jury rig after being
dismasted several hundred miles short of the finish line. (I'm
having trouble making this link work, but more info is at
Latitude38.com Go to lectroniclatitude and see the August 8 entry)

Sadly Skip Allen had to scuttle his 27' Wildflower in heavy weather
on the return to S. F.
