There really isn't much that springs to mind that isn't really pricey.
Many Swedish manufacturers use skeg hung rudders on some of their hulls, or did until recently. Rassy, Malo, Najad
are what I'm thinking about. Pacific Seacraft
, Cabo Rico
and Shannon for North American manufacturers, among others. Bowman from the UK. None of these are budget
yachts, even second hand!
If you have money
to spend then there's plenty of options. On a budget
, I really can't thing of anything that isn't really quite old. If what you are wanting is a big yacht, which isn't too old and won't break the bank, then the only options I can think of are boats from a mass production yard. Maybe the way forward is to buy a spade ruddered boat, Bav, Bene, Jean etc, then mitigate the effects of rudder loss; eg. emergency
rudder, steerable windvane
rudder, and sealing off the steering gear
from the rest of the boat in case of breach as I suggested earlier. Sorry I can't do better!
