Re: [Amel Yacht Owners] Rudder dismantle

I had the rudder down on our Maramu last spring
due to cracks & poor repairs done when the one of the previous owners replaced or repaired the rudder shaft following a hard rounding (pure guess work as we do not have any history for the vessel).
Step by step on how we did it on the hard
- lift up the boat so as you have at least an additional 60 cm ground clearance to allow the rudder to slip down
- shore up (vwith wooden block Under the rudder to support
- remove pilot link on rudder lever in cabin
- remove clamping bolts & nuts (3 x 10mm) on the square section top of shaft; grounding straps off; Watch out for shims on square section
- unbolt center support on rudder blade (called femelot in french); when bolts are unscrewed both flanges will open up on their own free will; do not cut grounding cable (SSB) linking to copper plate
- unbolt clamping bolts & nuts (3 x 10 mm) on base of rudder blade (called crapaudine in french);
- support weight of rudder slipping lever beam Under, & remove wooden blocks supporting the rudder. Bring down slowly supporing by hand (two strong men can hold with ne assistant to guide).
- rudder laid down on ground you will be free t inspect & check for cracks & faulty repairs (ours was stuffed with gel coat resin & fiber to fill in around SS shaft )
- do all necessary repairs using proper methods (clean down to sane material, & rebuild using resin fiber cloth before protecting)
- take advantage to check main hull on skeg for cracks wher half hulls were assembled together (weak point on old boats can genertae cracks and water ingress if damaged)
Then you will have to reverse actions to mount back in hull ...
another story requiring patient adjusting when bolting the 'Femelot' & the 'Crapaudine', to match 2 x 3 bolt holes, & to cut to length when securely fastened.
final step will be to replace packing on top of shaft; screwing on delrin nut after each navigation until well tightened (not too much !).
check bolts on square section regularly, they come unfastened with rudder motion if not checked.
Hope this helps
