What would the limits of manual hydraulic steering be in a slow speed displacement vessel? (before adding an electric pump would be necessary)
I don't have my head quite wrapped around this subject, I've only dealt with small vessel manual hydraulic outboards, and not much since I never encountered any problems with it.
Vessel in question would be a 65ft dual helm (pilothouse) sailboat of approx 50 tons displacement. Would a Capilano 1275V helm pump (one aft and one in pilot house) be sufficient with the appropriate cylinder and a large wheel (say 48inch) for a vessel this size?
-if it wasn't and steerage was tiresome is it simple enough to just add an electric pump?
-how often do these pumps run? or do they need to run continuously when power steering is needed? (power usage is a concern) and sailboats can have frequent small course adjustments.
-im assuming a system with a hydraulic pump could be used in manual mode with pump turned off, and maybe only switched on when conditions warranted?
-main rudder would be locked at appropriate trim and sailed via windvane self steering on long passages so a hydraulic autopilot would not be required.
Appreciate any info anyone may have relevant to the subject!
