[quote=Edchris177][quote=markito787]Hello,
Looking at a great deal for a Nacra 5.0 with a trailer. The owner, however, says he has not been able to find the rudders in his barn [/quote]
The castings are not to hard to find, the blades are the issue. You can easily find blades for the round bottom hulls, ie N5.2, but the skeg hulls are a much tougher find. If you look at the N5.0 or 5.7 hulls from the side, you see the last couple of feet have a definite rise at the bottom. This means that the rudder blades must be longer in order to keep a decent amount of blade in the water. Don’t be tempted to buy some of the shorter blades, thinking they’ll do, you won’t have rudder authority.
[quote=leeboweffect]Last resort is to build a Hacra, and frankly I would love to try this myself, hang a set of Hobie 16 rudders on it. You might even be able to adapt the Hobie castings.

This is actually a fairly easy project. It requires drilling one new set of holes for the Hobie gudgeons, & obviously filling the old, & making sure you mount the new gudgeons plumb. You can see that the top Nacra fitting was used, & new holes made for the bottom fitting. It looks like they lft the old fitting in place & just ground off the "ears".
The rudder pins will go straight in on a 5.0 or 5.7. Only the really old Nacras inset the transom, leaving a lip. Anything past about 1980 has flush transoms.
It had been done on a 5.2 we parted out, using H18 rudder assembly. I sent the entire 2nd gen rudder assembly to a fellow in Texas. It should work on a 5.0 if the blades were of equal length.
