I guess this also refers to the cobra thread too...
Slalom boards have to stay light, if you dont like it go freerace or find a brand that does a second "sturdier" construction.
I wonder what some people do to their boards, do they catapult in such a way that they hold on & sail chops down onto nose? Abandon ship or get some rotation on your catapult will mostly save nose & rails. If you're sailing some sort of surf/dumpy shorebreak spot then I get the crunched rails. Another thing I used to see often is guys axe kicking their board in water starting or instead of falling away from board dropping down onto board with knees. No board will survive these things.
I started sailing in 90s, since then i've had nearly 80 boards at last count (im sure i've forgotten a few), approx 2/3rds have been slaloms or speed. About half have been purchased new & in all those i've only had 1 warranty claim (touch wood), this was actually the very first new board I bought when I was 16, a cobra built strapper slalom which had the paint peel off the bottom but more dire the fin box delaminated.
I used to sail more & further for a long time im not a distance person, but I'm heavy & do like to push boards hard through the chop. Quite a few have started to go what I feel is a bit floppy (but those that purchased them have had many more years) or get some negative v but i've been happy with pretty much all of them.
I think only real damage has been snapping 2 boards (waiting on another not far from it), very occasional nose from hitting wildlife/sandbanks/rocks, heel crushing under footpads, fin through board, sailing into rocks or being careless & dropping board when putting up on rack. I do tend to hold onto boards for a few years until I see a change worthwhile changing for.
The majority of those slaloms is fanatic falcons (16) & isonics (11). Some of the old grey falcons of various years where a bit lightly built but I did a hell of alot of sailing on them particular old falcon 131 which felt no where near as solid as new falcons. Isonics the carbons always seemed a bit too light but aside from some of the early carbons snapping due to design & the 2017 & after debacles most have been great.
For those nostalgia guys sorry but alot of fibreglass boards sucked & so did the plastics compared to even freerides today. I preferred carbon to every plastic model ive ever sailed... thommens/sputniks, vivaces, fanatics, mistrals, tigas, hiflys always imo the carbon was nicer. Yes there were some nice boards in plasticy construction- the first non slalom board I learnt to love f2 Air, those blue/greeny mistrals but they'd be much nicer in modern carbon (& imnegra for those type of boards).
All boards fail including carbon arts ive seen die, not because there was anything wrong with the build but from receiving a ton of use. Until starboard went all hippie all cobra boards seemed to be pretty similar longevity wise (there have been a few constructions which seemed like a great idea which weren't). & from what i've had & seen in the vietnam built boards they really dont last much better. Warranties exist for a reason & unless it's poor material choice no brand is sitting above each worker watching them put down the laminates.
Wood I liked in some boards & it does seem to hold up well but it ages bad compared to a painted/tinted board. I've seen flexy boards last a long time & solid super stiff boards fail quick & vice versa on both, you just can't pick it & have to trust the make. Personally I prefer to stick to standard constructions... carbon, carbon/glass, carbon/innegra, carbon/kevlar or wood. No eco resins, no eco foams, no fancy carbons or other cloths (though I do have some basalt here to try out), bamboo don't know & be wary of nose protectors & deck eva foams they hide cracks & leaks.
& i think nostalgia guys also forget how many australian built "customs" ended up in landfill because they fell apart.
That all said I think my current 13 boards will probably be my last production boards & time permitting i'll start making my own. I've been saying this for ages though & get distracted by something shiney with new production boards

. Nothing much has or is likely to change with fin boards for some time, just changes getting tuned around sail/fin/pro riders or for yearly fashion/change for sake of change.
& carbon or glass nice & easy to repair, cant say same for plastic, innegra, kevlar, bamboo or wood.
