I believe the NACRA 5.5 could be made into a F18 without
<br>much cost. Someone or group has to come up with some
<br>North American rules or go with the EU rules. There is a
<br>group working on NA rules now but it looks like they are
<br>leaning in the direction that all boats must already have
<br>a one design class and meet their F18 rules also. Or at least
<br>all sails would have to be from the factory that made the boat.
<br>If Nacra comes out with a set of sails for the 5.5 that meet the F18 specifications you may be ok. I don't think you will see this as then you would not have to buy a new boat. I think in Europe you can use any sails that meet the specs. <br><br>
