Only a guess, but I'd put my money on batteries.

sort of agree with John.
This is a compression fracture you can tell by the way the surface has buckled upwards, means the board has bent a little. you can do this by a bad nose first landing.
Certainly the area all along the crack has to be ground back to see how much structural damage has been done, The crack may not go all the way through the sandwich, and the bond between sandwich and interior foam may not be compromised. but you need to check.
Just restoring the outer glass layer won't be enough if the whole sandwich is affected..

Sandwich construction needs a tension layer both sides of the high density foam. If that needs replacing, you have to carefully remove the d'cell, leaving about 1cm of underlying cloth, so the interior cloth is continuous in tension, when you lay new stuff over it..

Agree 100%!
I've always made my own boards, but age has caught up with me. So when I made my last board I asked Mark to vacuum the deck on for me.
I no longer felt confident doing this complicated job myself, I'm getting too forgetful and making mistakes.
Mark did a great job and I'm really pleased with the board, in fact late last year there's a thread about it here somewhere.

I'm guessing here, that that's where the bottom overlap finishes, so the rail is stiff, but the deck is flexing, creating that crack.
the foam underneath may or may not be damaged. If it's not damaged, you just need to spread the load on that flex point.
No superficial fix will work for more than about 5 minutes, there's a lot of movement on that fine line. you have to kill that movement first.

The pad will need to be rolled back, the damaged area sanded back to the underlying foam and then be restored, stronger than the original.
Otherwise it will just keep cracking.

This is all good info, and makes sense.
Sanded fins induce a boundary layer, consisting of small rotations in the water next to the fin, (turbulence)
I guess these keep weed away from the surface of the fin.
The turbulence also travels around curves mu better than a laminar flow associated with polished fins.
Too much pressure, angle of attack on a polished fin will produce separation of the flow from the fin, this will drag air down and kill lift.

So conclusion from this thread is, a sanded fin is much more user friendly than a polished one.
Any difference in speed is undetermined.

No same argument, laminar flow or boundary layer.

I forget the name of the guy, but he did some tests, with dinghys, towed 2 behind him and found the polished boat had less drag than the wet and dry one, but that was at a very slow speed.
I've no idea really, as you say it's a **** fight, people on both sides of the fence believing there argument is better.

My boards finished with 600 go well enough

various thoughts on that, depends who you listen to. I think it depends on the R number. and how smooth the foil.

A good boundary layer helps the flow stay in contact, and the theory is it's a water on water friction.
The boundary layer is created by slight friction on the surface, starts water tumbling over itself.

A polished surface can give laminar flow, so no turbulence, and any foil irregularities can cause separation and stalling.

the slower the speed the rougher the wet and dry. higher speeds benefit from finer wet and dry. a rule of thumb for us is anything between 400 and 1000.

However Fangy's latest experiment was straight out of the 3D printer with no smoothing and he said it went surprisingly well.

Personally I haven't noticed any difference.

looks like it's heeling the wrong way, need more lift on leeward side and none on windward

Nicely done mate, that will be a huge improvement. Just adding a flange to the delta's made them heaps better.

Sue, Ar you familiar with the technique of threading a cord through a sleeve with a safety pin?
It's a slow process with a batten but with any luck you don't need to go too far.

So you'd have to attach a cord to the batten somehow?

No, the technique is to grip the batten well before the break by squeezing the tube, then crunch up the tube in front of the batten. Grip the front of the batten with the other hand. Let go of the back hand and pull the tube straight. this will move the batten up the tube by the amount you managed to scrunch.

the batten could be broken, it would be unusual to just loose that much tension

i always wear booties, most of the year its too cold not to. I like the front straps tight, so i can only get toes into them. And a narrow but high rear strap which i can push my foot all the way thru for riding. I've tried all the variations and this works best for me.
Also found that when the sole of the bootie wears down it seems to get softer and grippier and more likely to get stuck

Mine slip when worn..when it's too light to get in the straps.
I get about 6 months from a pair but I average 2 sails a week or more over a year.

Its a dark art isnt it! Trial and error to find out what works
This was learning not to use old wornout straps 😎 much grippier than expected

That's nasty, a good way to break your leg.

wow that was a fun afternoon. swapped a lot of the junk in my man cave for a jar of honey, and listened to yachty's very interesting stories.

Just a preference from me. This is what I see.

The time is only readable if I halve the distance to the screen and squint, just making the font normal black would help.
I doubt I'm the only one that's interested in how long ago the last post happened.

How's this?

That's much better thanks!
