Wouter,
Comparing DN Ice Boats with landyachting is almost funny. DN class is well respected by all serious water-sailors. Karol (Poland) and Struble (USA) are great examples of the type of sailor involved (both multitime champs). Any "world-class" landyachters?
Even more crazy-comparing F16 World Champs with A-Class World Champs. Who is the F16 WC? Ashby, Melvin, or Booth would do "OK" against them-YA THINK? Maybe even Smyth, Struble, Guck, Hodges, Hall........?
HA HA
You mentioned Struble being given the benefit of the doubt when comparing favorably to John Casey or Heemskert (sp). I think that the last race I know that Casey and Struble raced against one another was at a Alter Cup which Struble won every race in the series. I could be wrong......
Regardless, sailors (keyboard jockeys) like you and myself are not worthy of making "calls" on some of the skill levels discussed. I am a "mid-fleeter" and I did see you sail a few years ago in Georgia. Have you been on a boat with any of these sailors or even in the same end of the fleet? Need I continue?
