Well I finally acheived another milestone...my first catapult . Was attempting to hook in harness (thanks to Red for lending it to me the other day) and finally when I did, I took off but it wasnt in the same direction as board. Lost cheap sunnies but was worth it .

Oh btw how do you remove a face imprint from the sail... did that on second attempt lol.

Ty to the guys at Connewarre this arvo for giving me some pointers. Now I just want to go faster

Wait until you get the catapults at 30+knots. Recently had one where I ended up under the sail still hooked in upside down. Another had me contemplating the damage mid flight before I had even hit the water and resulted in a boom and a panel of the sail needing replacement. Speedsailing gotta love it.
I amsure Elmo can give some style pointers.

Don't worry Pat

Your first catapult is generally quite rough, after a bit of practice you get better at them and starting introducing more creative elements to them gradually gaining more style with your efforts.

I cant see the 'GO' getting to 30+ knots so I will have to perfect my technique at lower speeds lol. Besides I think I need to get a helmet before I try anything too creative

Welcome to the club!

Take your mast, and move it so that it's touching the nose of your board. Where the board meets mast is where you need to pad. I prefer padding the mast, 'cos then you can see when damage occurs, unlike putting foam on your board and the first you know of any damage is when your board starts putting on weight

I saw a bloke recently that looked like he strapped a mattress to the nose of his board. Looked silly but after snapping my nose from a spekky catapult maybe a mattress is not so dumb. Perhaps someone can come up with an airbag system that inflates on impact.

OB64, they only get more spectacular, and just like Lao Shi indicated, you start contemplating mid flight "gawd, what sorta damage I gunna do this time"
Great to see another has the bug (wanna go more fast)
Try to limit damage to gear and not you, and yep get a helmet, I did, but a tad too late to save a few $'s

Congrats OceanBLue64... apparently holding on tight and going with it is good practice for the forward loop. Not that i'd know, just read it somewhere :D

I find I do most of my catapulting during water starts in gusty conditions :)

Look out for those empty plastic bread bags. Catch one of those on your fin when you're going full tilt, and you'll think you hit a brick wall! (And will have a most spectacular catapult)

Next time OB64, just sheet in hard with your back hand and your mast will miss the nose.

A forward is just like a deliberate catapult. You pull your sail across and forward and sheet in hard with your hands well back on the booms and the sail pressure just drives the nose straight towards the water. Ya gotta be nuts.

Is that really all it takes to stop a windsurf board? I would have thought (having seen some of the fin-gash photos floating around on the 'net) that the fin would just shred the bag!

It's physics Mr Bonk, if a fin hits your leg at thirty knots, your leg has a a lot of inert mass and is going to try and absorb the kinetic energy of the fin. A plastic bag is just going to wrap around the fin and provide a massive and instantaneous increase in drag.

Put the right fin and rig on a GO board ,move the straps outboard and it IS capable of 30+ knots.The hull is almost the same as the formula boards starboard make , it's just a little heavier.

It can, though when riding in weed prone areas windsurfers tend to use a specialised fin with a high degree of rake angle on the leading edge.
It's not a huge problem, plastic bags and seaweed caught on your fin are more likely to result in spin out than a massive catapult.

Plastic bags... try hitting a blue plastic fisherman's bucket at 20+knots. I haven't had a "rag doll in the jaws of a rottweiller" experience like that one in a long time.

I can recall reading, in a previous thread about catapults,someone hitting a submerged mattress manly in brisbane i think..
I catapulted on a seal one day up at lano..poor bugger didn't know what hit him.Cray pot lines are the ones to watch for in WA . In the arvo with the glare they are hard to spot

Years ago, a mate and some of his friends were windsurfing at Poona. One of the guys broke a fin, so came in and put another one in. Broke that one too in almost the same place on the water, so they went out to see what it was. IIRC it turned out to be some sort of large, submerged wooden frame that was anchored to the bottom. No buoy or marker of any sign over it

Wait until you start damaging your boards nose and worse, start damaging yourself. Thats when it becomes less fun lol .

I came in on a prity quick down wind run and went flat out into a sand bar. Ended up causing a lot of damage to myself in ancle deep water and was in hospital a couple hours after getting cleaned up. All is good now, it was more for precaution and the fact we had nothing at all back at the shack to help me lol.

Apparently at goolwa theres many obsticals that we never knew about until the water got so low:

- Straight out infront of the aquacaff theres a huge piece of metal, thought to be a old paddle steamer engine or something.

- Around near the barrage there is a sleeper pointing diagonally out of the sand, sometimes comes completely out of the water.

- Apparently around by the marina opening there is a old channel post which was broken or cut off or something which sits not very deep under the water.

- I have heard roumers years ago of a under water fence like the one at boggy lake running very close to the island.

- Also millions of glass bottles, which are mainly broken, scattered everywhere over the lake so watch out for them to, not so great for the feet.
