A challenge for GPS boffins. Store the locations of rocks and have the GPS beep a warning if you are on a collision course. it should be possible for the gps to filter the warnings as a function of tide and fin length.

After seeing that I think that it is only a matter of time before someone gets hurt bad, dont want to be a stick in the mud but sail there only if the tide is right and conditions allow it, thats some serious sh1t if you are going fast, fall and land on a rock.

I wont be sailing there after seeing all that, it aint worth it.

Be fkn careful you lot!


It's alright Minty, we know about it and take necessary precaution but making it of limits at certain tides (a rule Hardz likes to selectively obey)

Rocks are very spectacular as they leave visible damage on the fins, but we have more and harder stacks from hitting weed clumps.

Where a weed fin will normally bounce over a rock, a decent weed clump (½m²) can stop a weed fin dead or at least give you a very good look around the front of the mast.

For those unaware of what to look out for with weed clumps here's some hints

Small glassy patches
Stationary white froth
Seagulls and other birds standing on water

Same again, ask the local crew and we will point them out on the course if we get some metro crew down

Polarizing glasses help with seeing whats in the water just below the surface.

Here is a vid of me hitting the snot weed at around 30knots, scary what you sail does when you go over the handlebars like that. also there are two more hazards of Hardies featured at the end, sorry I forgot to add tunes to this edit

whoa Adam thats a ripper
theres lots of those swimming frisbees down there,
swimming around with their tails out of the water sometimes.
i had a sess down the bottom of A land back in feb, by myself, srrounded by at least half a dozen of them all swimming around with their tails in the air..quite weird but at least they where visible..those ones anyway..

Excellent vid Bundy, the rays are impressive. I have seen wing tips come out of the water about 5-6 feet apart. The mark under Pepe's board from a spine put up by one was pretty concerning too

Great vid Adam, Go to woe in a board length that hurts

Amazing seeing the deflection of the battens, I would never have imagined they would bend that much without snapping.

Good seeing the Ray and the crab net, at least they used the white floats, it's the clowns who have clear bottles on 50m's of rope which make life interesting.

Been meaning to put that stack up for a while now, if I had not got that snot the sand 50 meters further on would have got me anyway should never have run so far in with a 34 cm fin

It seems though that the statistics of crashing in shallow water aren't all that bad? You don't often hear of people getting injured? I suppose if you stay hooked in and hanging onto the boom you'll hit sort of parallel to the mast/water surface and none of your extremities will hit the bottom too hard.

Maybe not permanent injuries but they sure hurt at the time.
I haven't hit the bottom but have been swung around on my harness line so my back was slammed and hyperextended across the boom. I have heard of that happening to others too. You lie there stunned for some time hoping you havent fractured a vertebra (and grateful in a twisted kind of way that the water is shallow because you can't sink and drown).

So if you head from the Novara boat ramp toward Boundary Island you're at risk?
If you head out toward the scientific platform you're OK?

"

My stats were based on the three 40 knot-hit-the-bottom crashes I've seen at Sandy Point. Spotty, Sailquick and Mr love. They all hop up quickly and check the water depth a 2nd time. I've only been to Sandy Point a couple of time, I wonder how many crashes happen when i'm not looking?

(Spotty's may have been just under 40, Has anybody done 40 knots in the duck pond ?)

You will be fine Iif you stay outside the white markers when heading to Boundary and dont go wondering around inside if its a real low tide, . The guys down there will help with directions any time.

Ian , I was really lucky, it could have been much worse. I ended up on my bum in about 300 mm of water, if it had of been my head I think it would have been a different story. If there were rocks, I would hate to think.
The force of the impact sheered my Carbon boom in 3 places and snapped my SS spreader bar in half. The leeward rail of my board near the nose was compressed where it drove into the bottom after the fin grabbed.
The only injury I got was a really bruised hip and thigh, so my body obviously hit the bottom, again if I landed on rocks it would have been ugly.

We all know shallow water is dangerous, but is there really any difference between crashing in the shallows when you hit bottom, compared with crashing in deeper water when you spin-out and bury the leeward rail?

Either way the board stops dead and the rider gets driven. I have hit bottom and crashed plenty of times, but I've copped worse beatings in deeper water after spinouts.

That one didn't hurt coz I had time to hit the "eject" button after the fin let go.

It's the instant ones that get ya; the ones that leave you with, for example, your nose splattered all over your face.

The black patch of death which goes under his board just before the is a big Algae clump (no rock), as you can see it'll stop a weedy.

If you pause at 1.37 you can see it, the tan coloured stuff around it is also snot but stuck to the bottom, there is even fin marks just to the right of the patch where other fins have gone through leaving a trail in it ( your fin isn't necessarily touching the bottom).

We are already getting inundated with snot down on the run to about 150m out, in another month we will have mats of the stuff out there, some of which are that thick you can stand on them without getting you feet wet.

From now until it clears you either slog your way out through it, or walk down the channel and launch from the end, the deep water is the place to be.

ah the joys

Great vid - as elmo said great slow-mo of battens deflecting on impact.

I saw a small clump of seaweed yesterday - the first in about 2 years . Have to say we're really lucky here as I cannot readily recall the fin ever catching seaweed let alone having to dodge around big floating clumps of the sh1t. That said though I'd probably put up with your snot for some flat water.

No rock just a clump of snot slightly below the surface, you cannot see it until you are practically in it This one was a long way out too
