Thanks Wouter,
I guess the Bim 16 (1) is that boat, which is in the Texel-rating. If this is the case, I do not need to contact to Martien Kooijman, nevertheless many thanks for your offer. In fact my concern with the Javelin 16 is the weight. The official statements are 95-110kg (depending on the dealer)...
Cheers,
