Manual In-mast Furling Repair and Maintenance on the Main Mast of an Amel Super Maramu


Amel Super Maramu’s have many electric winches and furlers and after 20+ years of service, ours needed some serious attention. A nasty crunching sound emanating from the manual/emergency furler in the main mast meant we had to drop anchor on a sail up the east coast of Spain to take a look. After detaching it from the electric furler and foil I dismantled it to find a broken tapered bearing and some sorry looking oil/lip seals.

I eventually pieced together the service kit below and ordered one each from the UK companies (also listed below) at a cost of around £50 each. Luckily we had some ex-pat friends living close by who we could have the spare parts sent to and I managed to fix things back together while on anchor before *eventually* continuing to the Balearics!

Thanks to the contributors to the Amel forum for their advice and for the swift and friendly customer service from:
