Yes, designed by Peter Matkovich who seems to have a huge grip on the local market. Darren Clarke has some sort of ambassadorial role - declaring it the best course he has seen! - not sure if he made architectural input.
I think it is walkable for the young and strong, but no-one else. I think they intend most players to take buggies. Someone asked about the St Francis Links course designed by Jack Nicklaus and declared by him - so said someone who intended the opening - to be one of his very best (there's a surprise!). I forgot my camera that day alas so no pictures. But that course is not really walkable either - the "links" with the most elevation change in the world! I mention it here because my one rather depressing conclusion about the newer South African courses is that they are worshipping at the wrong temple - too keen on mimicking high end US style resort courses with bag drops, buggies etc. If ever a country was crying out for good caddie schemes!
Anyway.....Bob, I did not check the property prices. But I can tell you that prime real estate in the Western Cape is very expensive these days (albeit the currency is again weakening) although maybe not by the standards of where you are living! A friend looked at a nice beach house on Llandudno beach in Cape Town recently and that was about 2m sterling, or over R30m. I would think some of those bigger houses you can see on this property are selling for about 1m pounds. But bear in mind that although this is a spectacular golf course, you would think twice before buying a house in Mossel Bay which is probably the least nice part of the Garden Route. Additionally, the resort/accommodation part of this complex did not fill you with confidence and does not overall have quite the high-end feel it aspires for. The Nicklaus course by contrast i think has done this bit of the package better, although the golf lacks the same wow factor. It is, however, only 75 min from Humewood which remains the best course in this neck of the woods.
You are also right about playability Bob re the wind. I think the course is a bit too severe. Part of the reason in the end I did not play was because I was pretty sure my wife would not enjoy it - I knew she would like the views, but not the golf.
Not sure re the overseeding Tim - I am not the greenkeeper here, but they were certainly fiddling around.
I have not made it to Oubaai Jason! Apparently Simola, inland course near Knysna is also very nice.
