    Steering Effort on Sailboat w/ Hydraulic Rudder Control

    That is true, but modifying system for mechanical would be too complex vs changeng only clylnder... I know it won't be perfect but for now I am looking just for improvement. By your opinion and experience, what you think would be the best feedback, let say at full speed from 0° to 10°, 0° to...

    Steering Effort on Sailboat w/ Hydraulic Rudder Control

    That I actually what I am asking... It is linear curve, not a exponential? When I contacted sestar tehincian he told me that effort increases drastricly. That is why I started doing calculations in the first place. I tought it is an exponential increase, so I wanted to know by how much.

    Steering Effort on Sailboat w/ Hydraulic Rudder Control

    Now there isn't any effort needed to steer the boat at any speed or wave, I can't feel where is the rudder since have 6 turns from full left to full right...and when wave catches me I am steering on memory to maintain direction I want. I want to feel something but not too much, as well to...

    Steering Effort on Sailboat w/ Hydraulic Rudder Control

    Thanks for your reply. I was converting all to kilograms in order to know how much force I am going to feel on wheel. Becouse I am used to Kg, and know how much it is. If let say on 10° of ruder I get 10Nm of feedback force. Work to achieve this feedback force grately depends on how fast you...

    Steering Effort on Sailboat w/ Hydraulic Rudder Control

    By useing this formula P=(p*Q)/(600*n1) Or, Drive power = pressure * volume flow /600/total efficiency Result is kW * 1000 = W = Nm/s(?) (Nm/s)/10= kg*m/s (this is on 1m radius) For 35cm radius (70diameter) = (kg*m/s)/0.35m Pressure = 3,95bar For Q i used this formula; Volume flow = pump...

    Greetings to all, I recently jojned this forum in order to find solution for my steering problem on sailboat. https://www.physicsforums.com/threads/calculateing-necesary-effort-on-steering-wheel-at-hyd-operated-rudder.1000007/ It isn't easy, and last time I was playing with Newtons, Newton...

    Steering Effort on Sailboat w/ Hydraulic Rudder Control

    Greetings to everyone, Recently I bought sailboat with rudder which is actuated by hydraulic oil by cylnder and pump at steering wheel. I have been trying to calculate steering effort(feedback) on my hydraulic operated sailboat if I change my current cylnder,but nusucessfully. Problem is that...
