[color:"blue"] Taking the current Tiger which has probably changed least, over the last 5 years all their sails, spreaders, trampolines, front bridal arrangement and rudders have all changed, not to mention the introduction of self tackers/snuffers which were both around 4 - 5 years ago. With the exception of the (very) recent bridal upgrade, all performance related changes are easily retro fitted to older boats. [/color]
Even though the Tiger is the same shape does not mean it has not changed. There was a time that the Tigers were coming in a bit heavy, around the Worlds in Santa Barbara. I talked to factory people while I was in France and they said they have a new lay up that allows the boats to be stiff, what they were trying to achieve when they got heavy, but gets them back down to the minimum weight.
I may have to agree with TeamVMG about getting a newer boat. I sail mine alot and have been told by very good friends that I should consider a newer boat. I was thinking a suit of sails was in the cards for me to get the speed back. We are still sailing competitively but do not have the blazing speed that made it easier to get around the course well even with a couple of minor mistakes.
After sailing a new boat on the Sunday of the last regatta, it happened to be an Infusion, I am thinking, thinking, thinking.
