I recently sailed my 1988 Nacra 5.5 uni in low wind, and have a few questions...

1) Would it be possible to install an after-market jib sail on this catamaran? If so, where would I go, and how would I hoist it?

2) One of the hulls has a slow leak. I suspect it is where the fibreglass hull meets a non-fibreglass material on which the rudder is mounted. The fibreglass portions of the hulls generally look good, with no soft spots. How would I find and patch that?

Thanks!
