Mirage 27 (Perry design) - rudder repair

Hello there,
I am considering the purchase of a well kept (later model) Mirage 27 that looks great. Only concern is that the rudder is showing longitudinal cracks on the leading edge towards the bottom. Would be great to hear of other's experience with this.

Thanks,
ScottyF

Re: Mirage 27 (Perry design) - rudder repair

This has been discussed in a number of threads on here. Try searching in the search function here with terms like "Cracked rudder" or "Water infiltration in rudder" and "broken rudder".

People have talked about a process of ensuring that the rudder is completely dried out inside and then refinishing the crack with epoxy or reglassing it. I've not had any personal experience with it, but you already seem to be ahead of the game compared to the guy who recently posted on here that his rudder fell completely off in the bay just outside of the marina. He was going to have to start from scratch to build a new one.

Re: Mirage 27 (Perry design) - rudder repair

Thanks for the reply "Midwesterner". Appreciate the comments.
Totally agree, cannot head-out with rudder risk. This said, was wondering if others had repair experience of this type with the Mirage 26/27. I've heard of folks drilling/draining followed by epoxy/glass. Incidentally, a company in Ont. will build you a spanking new rudder (with old rudder/post supplied) for ~$2800. Would like to hear from someone that has taken the repair on themselves.

Cheers,
Scotty

Re: Mirage 27 (Perry design) - rudder repair

If you are not intending to win any races, the repair is fairly simple: dry it out (by keeping rudder in dry, warm place for a few weeks), scrape clean the cracked area, apply one narrow strip of fiberglass fabric saturated with thickened epoxy to cover the cracked edge, wait for it to cure, sand it smooth, paint the rudder with good barrier paint.

Be kind, for everyone you meet is fighting a hard battle.

Hello,
Anyone familiar with how to pull the rudder on a Mirage 27? (pedestal steering)

Thanks,
Scott

Re: Mirage 27 (Perry design) - rudder repair

All rudders are wet, or will be is my feeling on the topic. Most wheel steered rudders have a cable quadrant that has a split hub. If it's a cable type of steering helm. The rudder often has a tube with thrust/support bearings also.

Re: Mirage 27 (Perry design) - rudder repair

am in process of doing that this winter. Mine is wheel steering, does not have a emerg tiller connection. To drop rudder, disconnect quadrant, place support under rudder before unbolting rudder post at top near transom. Then unbolt at transom then drop rudder after removing supports. May have to dig hole under rudder to get it out if too short to the ground. Then i would dry for a couple of weeks, then drill and fill, then glass several layers over crack, see youtube videos. Small layer first, make wider layers, extend to about 4" down either side to reinforce, let dry and sand and paint. Good to go for next summer.

I want to be a sailor when i grow up, my wife says i can't do both.
