Re: [Amel Yacht Owners] Spreader cracks

sorry to be late with this reply but I would like to add my input. Twelve weeks after taking delivery of my new SM2K I was at anchor off Cartright Labrador after a voyage from Ireland to Greenland. Whilst doing my daily walk around the boat I did notice a fleck of white paint on the deck. There did not seem to be any obvious source of the paint and being single handed, an up mast inspection was not possible at that time. I concluded that the fleck of paint may have been blown from the shore and continued my voyage to Newfoundland. A week later whilst on a broad reach with the port tangon poling out the genoa, I suffered a dis-masting after the port lower main mast spreader failed at the weld to the mast bracket.
Forensic analysis showed that the weld had not been properly prepared, too little heat had been used and too little argon used as well. It turned out that Amel had changed fabricators and the new company clearly had failed to do the job properly. The boat built prior to mine (413) also discovered cracks in a spreader just prior to starting a crossing to the Caribbean. By chance they had to go up the mast to re-rig a flag halyard and noticed the failure.
In my view, one of the least satisfactory design features of the Amel is the way in which they construct their spreaders. Unlike almost every other manufacturer they rely on butt welding the spreader extrusion to the mast bracket. Unlike almost every other manufacturer there is no insert into the extrusion with pins or bolts so if that weld fails, as mine did, it is not fail safe. The broken spreader will come off the bracket and the side support is gone. I did suggest to M. Lemonnier that an improvement would be to drill a hole in each end of the spreader and fix a tie rod between the end plates to at least keep the spreader in place should the weld fail, but he dismissed the idea outright.
To be fair to Amel they did change the spreaders on 30 boats that had been built with spreaders from the new fabricator. However, you should be aware that the welds are not normally subjected to NDT testing and so I would suggest that you keep a very close eye on your paint cracking. You may be heading for a spreader failure further down the log.
