simmss CA Rider Location: Australia	Ding Hi James, The mast base bolt on my universal sheared in half while sailing and apart from a 1 km swim I now have a ding created by the impact of the mast - see attached photo. Just wondering if I need to do anything to avoid future issues or just leave it? Thanks, Scott.

swalsh CA Team Australia	Hi Scott, A good little trick to remove dings (as I recently learnt from fellow CA rider Christophe) is to apply some heat from a hair dryer on the dinged area. This gets a lot of smaller dings out. Works a treat! Be careful not to over do it though Oh and yeh, to avoid future accidents such as this, you may want to renew your uni more regularly

ChrisBEL29 CA Team Belgium	Hi Steve - funny that you remember that trick Scott - the hair dryer does work. You may not be able to get the ding out entirely depending on how deep it is, but you should be able to at least partly take it out. Go step by step, don't overheat it too long. Also, avoid stickered areas - you don't want them to come loose (thought from the picture it seems that won't be a problem for you). As for uni's, check out the chinook ones. I've been using those intensively for a couple of seasons now without breakage (bolt and cup are one piece). Be sure to regularly check the joint though for cracks, and replace it if needed (very easy and only costs a couple of $$). cheers christophe

simmss CA Rider Australia	Thanks for the feedback guys - I'll break out the hair dryer and give it a go. As for the uni - yes this was a chinook and the interesting thing is that the uni bolt failed at the point where there is a hole in the bolt (can just make this out in the image). The hole is normally obscured by the deck plate, but if it wasn't then I think a lot more people would be questioning the strength of this design. I've moved to another brand and I'll be disassembling it to look for similar weaknesses. Thanks again, Scott.

Dodo CA Rider United States	Hi Simmss, that is a big ding. I think that you would be much better off doing the job right: sand + fair + paint with some new acrylic dust for no-skid. Otherwise just leave it alone, I have 3 dings on my CA 58 (including the one that came with the board at delivery) and I just live with them ... Seriously, trying to rise such a sizable ding with a hair dryer might just get you a further weakened spot plus some nice peeling paint!

ChrisBEL29 CA Team Belgium	Hi Dodo - I really doubt whether this would aggravate any structural damage that would have been caused by this ding. From the photo it looks more cosmetic than anything else, especially knowing the tough pro construction. Also, this area (almost in front of the mast rail) is not critical in terms of foot placing etc. I would therefore be very hesitant to start sanding, faring etc. Anyway, it would be good to know from Scott what's been the result for him. Scott, any news? cheers & happy 2010! c

.g.e.o. CA Team Italy	Made 3 slight dings on my new SL66 PM. It hapened when a small wave came and "printed" the mast extension ring rim on the deck by leveraging the board up against the sail laid down in the water (OUCH!!! Need to be careful from now on). Very slight, but disturbing; not even easy to detect, but you know how it is, you KNOW they are there. Applied hair dryer very carefully, and the dings simply disappeared. Result far beyond expectations. Thanks for the good advice!

ChrisBEL29 CA Team Belgium	Hi Geo Good to hear someone confirm that it does work - at least I wasn't imagining it Btw, how do you like the 66? I sailed James' one only once and was pretty stoked about it (I'm now anxiously waiting for mine to arrive). This board will be my benchmark board for slalom racing with 7.6 & 7.0 - should be a killer combo What fins are you using with it? Cheers from a frozen Belgium c

.g.e.o. CA Team Italy	Hi Chris, unfortunately i didn't sail the SL66 enough to comment about it. Anyhow, it feels just the perfect size board for a 7.6, and it seems to retain all of the quick attitude of the 62, only with more power and a better support out of the jibe... which makes it a perfect fit for 7.0/7.6 weather, of course! I just received a Talon 40 to go with it, and I'm eager to compare it against my Tomcat 38 and test both thoroughly.

vincent CA Team France	The 66 rocks ! I've tried it with 6.7 (no 7.6 to try at this time) with 42 Venom in light winds. Very light under feet, lot of power to get planning and go upwind. Super comfy ride, as usual with CA slalom boards. The jibe is very easy, easier vs SL70 for instance. No enough time to check boat speed but it seems super fast. I would say it's a "small" version of the SL70. I should be a must have board very soon for both freerider and serious racer !

Dodo CA Rider United States	Hi Chris, I do not know, that to me seems quite a long and deep ding, not a superficial one. Sanding a small area, putting on a little bit of fairing compound (use 3M Acrylic), sanding again and painting with a finish of some acrylic dust takes maybe 1-2h of work for a perfect job. Heating it up will make some of the ding disappear, but it just a cosmetic fix, and you do not know what is underneath. If there is the beginning of a crumbled divinycell or styrofoam underneath, as it is likely because that was probably a solid hit, rising the ding could make the matter worse and spread the crumbling. If you try to rise the ding I would suggest that you inject some urethane (or some heavily microsphere loaded slow-curing epoxy) just to be on the safe side. Or keep your dings: these boards are quite fragile and it is an uphill battle to keep them looking good. Some more fabric on the rails/nose (and deck judging by a previous post getting 3 dings while standing still) would be nice.

.g.e.o. CA Team Italy	Ouch... wasn't the 66, it really was my new 58 that got the dings cured. Anyhow of course nothing changes about the hair dryer: it works (with small dings at least). Doesn't seems to me that CA's are easy to ding. We can discuss about "personal experiences" as long as we like to; but after all, why should CA's be easy to ding? They are not excessively light, so one could figure them out just like "normal" boards in which the place of most of the putty and of some excess resin is taken by extra reinforcement. Doesn't sound more fragile at all.

simmss CA Rider Australia	Yes, I can confirm that the hair dryer does work but didn't remove the ding entirely. I didn't want to push it and I think Dodo you're right that the ding is too big to remove this way. Also, I visited a professional board repairer who gasped when I mentioned it so better to heed that warning or keep it to yourself

pettersevenius CA Team Sweden	Looking at the picture it looks more like a depressing from the mast and in this case it feels more like a beauty fault than something that you immediately have to fix. Nothing that can suck in water and nothing that really affects the board's performance. I would be very careful of using a hair dryer. This was quite a long ding, trying to expand the Divinycell with heat to its original form might work but you will never get back the original strength, it may instead become weaker than letting it be. And be careful so you don’t over do it and end up with delamination… I would only use the hair dryer trick on really small dings but on the other hand, the affects on the overall strength is it probably marginal

ChrisBEL29 CA Team Belgium	Obviously it all depends on the nature of the damage. In case of structural damage - which is impossible to ascertain from a picture - the heat application is useless and counterproductive. It is only a little trick for 'cosmetic' purposes, and should in any case only be applied with restraint. As always, in case of doubt: contact a professional However, if applied in this way and for this purpose, the trick does work, and according to my sailing buddy - engineer & board builder in his time - is harmless. My experience only confirms this. c

pettersevenius CA Team Sweden	You are absolutely right, my point was mainly that you should only use this trick on smaller, harmless damages to fix the 'cosmetics' and don't over do it. We all know that a well-kept board gets a longer and happier life and even better results, so nurture your boards with lots of love!
