I think you will find the Mainship Manual in one or both of the following locations.
TF Library section... website upper right corner is a Library button. I think I posted a link there that gets you to at least the later year MS manuals.
Or go to my Bacchus website (link below or in signature if using TF website) and look under Useful Nautical Links - Various MS Manuals
Only problem is the MS manuals IMO are not very useful as they are light on details and specifics.
