thanks Faster, thats a good idea, we where speaking about inhaulers earlier today, just trying to get as much info gathered as possible before thinking about ordering new sails, where we put these tracks will determine the shape of sail etc.
We are trying to get hold of a used #3 to do some testing with what you have suggested.
In the meantime its good to get opinions, i found another post on sheeting angles and to quote 'You can't place the jib tracks of a Columbia 26 or Catalina 27 at 7 degrees and get a good result. The keels of those boats will stall and the full bows would need more power to push through any swell.' Kind of wondering if thats similiar to our boat, but a practical test with inhaulers will obviously be the best thing here.
Absolutely irrelevant to your boat. These are both mast head rigs. Why not write a quick email to Oyster and ask for their thoughts? You'd be surprized how much info you can get from a manufacturer even if your boat's been out of production for many years.
