The problem with windvane self steering on a small light displacement boat
is the frequent changes of boat trim when the crew moves about..
I have never tried a windvane on such a small boat but have worked with
sheet to tiller and other systems in the past. This crew movement was always
a problem..
I have read of small boat single handers doing ocean passages and they
discribed the same problem.
While it is true that a windvane should maintain the course, relative to the
wind direction, the changes boat trim is going to still cause problems.
However, on a boat with a heavy center board, where crew dispostion isn't
critical, it may be possible using some of the simpler methods that have
been devised over the years.

Well - I'm not looking for a boat design. Let me try to make myself
more clear.

[from a New Zealand site - Boat Books Ltd. ]
WIND-VANE SELF STEERING
By Bill Belcher. Pbk, perfect bound, 240mm x 170mm, 128 pages,
monochrome plans and tables.
This classic book describes the theory, principles and practice of
wind vanes for self steering. It tells the blue water sailor how to
construct his own wind-vane self steering system, including full
working drawings.
Wind-vane Self Steering is generally regarded world wide as the
definitive work on this topic and currently, as far as we know, is the
only such work generally available.

The crew weight issue is interesting. I sail a couple of small boats which
do not have rudders. There is some resolution of forces based on body
weight, boat displacement, sail area, and wind strength which determines
whether a boat can be sailed with or without a rudder or wind vane. It
should be possible to work it out mathematically. I find it easy (and
comfortable) to sit on the bottom of the boat facing forward and steer by
leaning from side to side while working the main sheet. When close hauled
with the sail pulled in tight I sit still. On a boat the size of a
Wayfarer or Albacore (15 ft, 250 lb) I'm sure I'd find that difficut to
do. I've done "wet assed" sailing in Albacores. It isn't enough to sit in
the middle of the boat, you have to get your weight out over the side. The
alternative to "sitting out" is to let out the sails to reduce power. A
wind vane will not let out the sails. However if you can depower
the sails by reefing, and accept lower speed, it should be possible.
Performance would depend on the variability of the wind. Might not work on
gusty days. Some cruising sailors simply tie off the tiller with shock
cord in steady winds. On a small boat you'd have to tie off the tiller and sit
still, like I do in my rudderless boats.

What type of rudderless boats are you sailing? Spent a long weekend on
the east coast of Spain a few years ago (near Barcelona) and saw their
rudderless cats. Wanted to sail on one SOOO badly. There was also a
writeup in WB (I think) on those same boat, showed one of them
pitch-poling 8-( They were a rather narrow (by Hobie standards) cat.

variants...

look in my website under Boats, then DogSkiff and Loonie
I go the idea from TF Jones ("Boats to Go") who sailed an open kayak
without a rudder but only downwind. I wanted to have a boat I could cartop
and portage like a canoe so I left off the rudder and tiller to save
weight and space and to have one less thing to carry. Both of my boats
sail upwind. I worked it out that because there's no rudder you have the
daggerboard at the leach of the sail instead of 1/3 back from the luff.
I've had the DogSkiff out in a chop and was surprized by its steadiness.
The only problem is I have to use a paddle to tack and its a struggle in a
stiff breeze waves to get the bow around, and waves make it worse. Maybe
with a better sail ...
There are photos somewhere on the Internet of the St Lawrence skiff
rudderless sailing races many years ago.

Navik's are fairly light (about 35 lbs) but I think they would be overkill
for that size boat. Perhaps a simple sheet to tiller rig (bungee cord)
would be o.k., given that you probably won't be sailing it overnight?

Thanks everyone for your responses. I'll start by expermenting with a
sheet-to-tiller system.
Here's a couple of good references with pics that I found:
