@sailpilot,
I think you might be right on the money there. I wouldn't be surprised to see 2 or more board makers disappear from the market by the time 2010 comes around. I don't think the fact that they increased prices by $200 will have a lot to do with it though it will be mainly due to economic factors.
Re price development in the windsurf market, you will actually find that sail prices haven't increased that much over the last 10 to 15 years. I think the arrival of budget brands like Gun Sails have put kept prices down. This hasn't happened in the board segment to the same extend because of the complexity of making a board compared to manufacturing a sail.
From what I have heard from a guy in Germany who used to own a windsurf store but now has gone into distribution, Cobra charges about US$350 per board all depending on what materials you pack in.
It's all a margins game. Let's say cobra increases the cost by 10%. Assuming no one in the supply chain absorbs the increase but instead hands on a 10% increase based on their sale price you end up with RRP going up by 10%.
The problem with this equation though is that the windsurf stores will suffer the most as they deal with the market directly. And the market will determine if they are prepared to pay the prices or not... simple supply and demand issue.
So back to the original question re price increases... do a simple comparison for different markets:
Price 20, 15, 10, 5 years ago and today
Price 20, 15, 10, 5 year ago and today inflation adjusted
compared the different market taking changes in exchange rate into consideration
don't forget to consider changes in import and sales taxes
I think you will find that boards actually didn't increase in price along with inflation which would mean in relative terms boards actually got cheaper over time. Also consider that demand has dropped over time which would also have an impact on price.
