The relative windsurfing boards post has already become very heavy (and it is not yet finished), so I decided to create a new post for SAILS, FINS & other windsurfing material.

FINS
Christian Koester fins
C. Koester, has been one of the first guys to realize the importance of the fin and giving the proper attention, he focused on them in order to improve the performance of boards. Developing, shaping & hand making them by himself, he created beautiful & effective fins for all disciplines & categories. Starting back in 1985 he created complete fin lines for major players. The effectiveness of his designs goes until recent times and as a proof, many of his original fins have been copied.
Here we have the full fin range for the LIPSTICS company, with no less than 7 fin lines – back in mid ’80’s
For 1999 Mistral, in order to upgrade their boards, asked CK to produce fins for the complete range of their boards, and CK created those fine looking, hand made & great performing fins with extensive use of carbon!
