Hi Guys,
This is turning into an interesting thread and is now taking a new tack. I'd like to add a few thoughts if I may....
It seems that many people have unrealistic expectations of what warranty on equipment actually is.
Warranty of most products covers defects in materials and workmanship for a period of 12 months from the date of purchase. (Most products do not come with 12 months, however Australian law dictates that retailers offer 12 months warranty regardless of manufacturers warranty in many cases).
The warranty covers things like a defective foam blank with an unusual weakness from a problem in the manufacturing process, or if the layers of fibreglass didn't bond properly due to not enough resin (dry layup), delamination of layers or top sheets, or some other such thing. All these are problems made at time of manufacture. If a board lasts more than a year in normal riding conditions, then it would indicate that there was no original defect in materials or workmanship, otherwise the problem would have shown itself long before the 12 month warranty expired. Most serious defects will show themselves in the first few hours of riding.
If you talk to any surfboard shaper, any kiteboard manufacturer etc, they will tell you that the constant flexing of the board slowly fatigues the materials over time and that eventually, the board will likely, eventually, succumb to failure of the materials, same goes for kites, in fact all things.
Even in passenger Aircraft, Boeing and other manufacturers have a wing of each aircraft on a hydraulic test bed which continually flexes the wing to normal flight tolerances, the wing is loaded both ways and is usually thousands of hours ahead of the first production wing so they can inspect for fatigue cracks (which DO appear) well before the first aircraft will start to fatigue so they can send around ASB (Aviation Safety Bulletins) to inspect in certain areas for cracks.
The public want boards that have nice flex and are light weight, but they also want them to be strong, it's a trade off. If you want a super strong board, then it will be heavier and will flex less and be less fun to ride.
One of the most beautiful boards I ever rode was an Airush Pre-production prototype shaped by hand by the late Colin McCulloch. The board was feather light and was absolutely heaven to ride, a real work of art. A rather rough rider took it for a ride to learn kiteloops and broke it almost immediately.

The buying public are a rather finicky bunch and will often overlook a heavy board for a lighter one, but will then loudly and often publicly complain if the board breaks.
In Hotballs case, I think KP's offer is a good one, and more than reasonable. It sounds like the board broke through normal wear and tear and the failure was compounded by scratches which weaken the skin. The skins of boards both top and bottom deck are an integral part of the structural integrity of the board, if it should become scratched or scored, then it will weaken the entire board and setup a weak point where a point bend may form abnormally loading the core, leading to ultimate failure.
Wood core boards also break, they are a lot stronger than foam core boards, but are not indestructible, especially if you are 90 kilo's plus and jump.
What can you do to care for your board?Firstly, don't ride in water so shallow you may hit bottom, especially reef or sharp shells in sand. Sand also wears the board so don't ride up the beach, it may look cool but it IS damaging your board. What do you think they make sandpaper from?
Of course UV will effect the strength of the resins in the board over time so keep them out of direct sunlight as much as possible when not in use, this is why retailers recommend board bags!
If you jump big and come down hard, butt check the landings to take the burden off your knees and the board itself, or kick off the board before impact. Land lightly in a controlled manner if possible. If you drop like a stone from 20 feet and land on your board, imagine the loads on the board, you'd probably freak if you saw how much it flexed.

And last but not least, just wash the board off in fresh water if you can, it helps prevent the pads and straps from aging, helps to prevent metal parts from rusting (yes even stainless rusts, especially chinese stainless) and keeps sand from scratching the board surfaces.
Anyways, sorry for the long post, hope it helped.
Cheers,
