Hi Prowler
I dived in sandbaai and Onrus which is just before hermanus about a month and a half ago and we had a blast we shot galjoen (but the seasons over pity some nice sizers), Butterfish, John Browns, Kolstert/Dassies, Hotties and all the typical reef fish. We got a nice mixed bag and nice sizes just offshore. Right in front of the Caravan park by Onrus and moving towards Klienmond side there are nice Reefs with ledges which drop off deep. In 10m of water. If you diving off a boat stay in front of sandbaai and onrus caravan park there as also nice reefs which we dived.

Good luck Have fun and post some pics of what you got would love to know how it is now as i dived in winter.
