I am a big fan of the Lofrans' Tigres windlass
and have run maintenance
on several boats of charter
companies, who call it ďthe unbreakableĒ windlass
What better proof than the fact that it has zero plastic parts
As far as I know, there is indeed a change in shaft diameter made in 2006 by Lofrans', since the motors in the market with the previous (bigger) shaft size are motors over 2500W!
Despite this change, I have never seen a broken gear
Regarding the motor change I assume Lofrans' had to find alternative suppliers due to supply chain problems during the COVID period to support their high availability and service
There are 2 different EUROPEAN manufacturers of the same quality supplying the 1500W motors. I have serviced both versions and they look perfect to me and not at all Chinese.
Regarding the technical support, it is obvious that you have not contacted Lofrans' directly but a local service
station, since Lofrans' has established a ticketing system where I register my warranties, and everything has been resolved in less than 2 days!
