Default Nautical Development Offshore 40 Mainsail Furler

Hi everyone,

I recently purchased a Nautical Development Offshore 40 built in 1984. Not many of these boats were built and the company is no longer in business I hear.

As part of the improvements that showed up on the survey I had all the standing rigging replaced and upgraded. Part of this process was removal and inspection of the in mast furling system which is a Schaefer 1000. After the rigging company replaced it in the mast when I try to deploy the main the furling tube tends to bend out of the mast housing at about mid way up the mast and binds preventing a clean deployment of the sail. I suspect that the furling rig does not have enough tension on it.

I spoke to a rep from Schaefer on the phone about the problem and to ask about how much torque it should have but the rep told me it was not designed as an in mast system originally but a couple of companies (Cabo Rico and Nautical Development) used it as an in mast system. She didn't have any tech specs so wasn't able to answer my question.

Does anyone know how much torque I can tension the system to. It has one main nut clamping the rig to the mast at the base. Obviously I don't want to over torque it and damage the bearing. Any help would be greatly appreciated.
