This popped up in my FB feed... Some potential for that north wall. Wedges? Right hand point like break?

Already under construction looking at Google Maps...

Perhaps something in south through to east swells, though I wonder how that curved section of wall reflects energy. All the good breakwall rebounds have long straight lengths that face roughly towards the swell source.

Slightly OT: I recently found an 'SOS - Save Our Shallows' sticker from the campaign against the first iteration of this project.

That was 36 years ago.

you would think with a bit of thought it wouldnt be hard to make a surfable reef off whats already been done .....

A lot of breakwalls create wedges but two i know of just create a shallow sandbank around the groyne.
no wedges on those two. I agree with Stu, that breakwall looks like it doesnt face east enough, maybe a north swell would create wedges..by the way even though i ride a bodyboard, i find Newport wedge the most over rated wave in bodyboarding next to waimea shorey.
A certain natural rock wedge on the south east coast needs ese swells for wedges, the beach faces north east but the swell needs to hit the rocks on an angle.. which create peaks about 200-300 metres up the beach, you can take off close to the rocks on the inside, link up with an incoming set, pull into a 5 second tube launch an air, off the back continue on the sidewash standing up and continue to link up three or four waves with different airs off the back of each wave in the set...untill eventually you pull into a closeout...better than south straddie imo.
One of the only places ive ever pulled a twisted air reverse..also one of the only places i can do airs on a shortboard.

I live in the area.

The rock wall has been finished months ago and the marina is ready to be used.

I have been keeping an eye on this spot for long enough to say that it produces zero banks at the moment.

It's weird as the middle of the small leftover beach to the North seems to attract a lot of swell energy, mostly close outs and north of the entrance tgere are a couple of average reefbreaks that occasionally produce ok waves but around the groyne formations, Northand South, you get nothing as it seems to be all too deep.

I hope it changes but I don't think that we have enough sand flow in this area for this to happen.

Yeah, the south coast doesn't have a conveyor belt of sand in the longshore current, such as the NSW north coast does - they're all embayments - and the marina isn't large enough for a tidal delta to form anywhere.

Reckon if a wave hasn't formed yet, then unfortunately it won't form.

When I did the wave tank physical modelling for my reef concept (see video on offshoresurfreefs.com ) at the UNSW Water Research Lab Manly in 2004, the wave tank was setup for the modelling of the
proposed marina breakwalls which are now built. I asked the Shellharbour Council engineer in charge of the project at the time if they would consider incorporating a surf break into the nth breakwall, as it would have been a great location and a unique opportunity for a new surf break. Reply- good idea but no budget for this, and safety concerns over conflict between boating using the marina entrance area and surfers.
