Re: Cable vs Hydrallic sterring

There is a thread on the forum by delmarrey showing his conversion to hydraulic steering. Its worth searching for.

Being the nice guy that I am ...

Re: Cable vs Hydrallic Steering

Hydrallic is the only way, no weather helm or flogging with an auto pilot

Re: Cable vs Hydrallic Steering

On the other hand, no rudder feedback with hydraulic; I hate the hydraulic but other projects have always taken precedence.

Re: Cable vs Hydrallic Steering

I have Marol hydraulic steering at both inside and deck helms on my 41 foot steel pilothouse cutter. Wouldn't have it any other way, as the forces exerted by the transom-hung rudder are considerable. I will be installing a second ram for backup and for the ComNav autopilot. Both products are more "commercial" than "marine" and I encourage this approach over the standard "marine" brands for a 48 foot 40,000 pounder. That's trawler sized, and you can't be dicking around with something made for a weekending Hunter or Catalina.

Hydraulics need some knowledge for maintenance, mind you, but are generally reliable. No truck is steered by a quadrant, and quadrants take up space and have to be designed carefully to space out stresses and to guarantee access. Some boats are terrible in this respect and to re-reeve the steering cables involves disassembly of the aft end of the boat.

At the same time as I have hydraulic steering stations, I have a tiller head, a hydraulic bypass valve, and a tiller with fittings for a windvane. The idea is to have two completely unconnected ways in which to helm the boat, one amp-munching, hydraulic aided autopilot for motoring, and the other line-controlled, amp-free, deck-accessible windvane for sailing.

I'm designing and installing for offshore use. Your mileage, etc. etc.

Re: Cable vs Hydrallic Steering

I'm set up the same as Zee's boat.

Cable IMO has better feel, easy to work on and a piece of cable makes repairs cheap and have all necessary parts to make a repair anywhere.

No leaking or blown hoses to contaminate the bilge...

I think you will find that all the hydraulic steering manufacturers offer a valve which allows some feedback to the wheel - can be manually or solenoid switched from the cockpit.

Hydraulics gives you options - pumps of various sizes so you can choose your power - even power steering option for heavy weather, back up systems are easy. Very reliable system. But you should have a back up of some sort - hydraulic, wire, extra rudder, whatever. Since you already have it , why not go for hydraulic and leave the wire system in place as back-up.

Re: Cable vs Hydrallic Steering

I personally prefer forward facing direct rack and pinion if one has an aft cockpit--There are no cable runs or hydraulic lines below deck to take up space, minimal parts to worry about, simple maintenance, and easily accessed from the cockpit by removing the helmsman's seat, and one has the option of steering by tiller should something go wrong with the rack and pinion--or if one simply prefers tiller to wheel.

Just because you don't feel it, doesn't mean you don't have weather helm.

Re: Cable vs Hydrallic Steering

Simply restating the above posts -
- - Hydraulics are much more versatile and easy to install and maintain. But have no "feel" or feedback from the rudder.
- - Cable/rod/chain steering is more complicated with more moving parts, but has positive feedback to you at the wheel. You can feel what the rudder is feeling.

It all depend of the ratio between the pump and the ram, a balanced rudder may have also little feel.

Re: Cable vs Hydrallic Steering

Having two helms (pilothouse) we have cable steering in the cockpit and hydraulic at the inside station. Completely independent systems, if one goes down a quarter turn of a valve at the inside helm and you are up and going again. I much prefer cable or R/P because of the rudder feel, but our previous boat was all hydraulic and you get to where you can "feel" the rudder by the amount of effort needed to turn the wheel, (in higher winds, forget it under 15 k) even though there is no direct feedback. Hydraulic is the only way to go if the installation is going to be complicated by long runs, etc.

Re: Cable vs Hydrallic Steering

Anyone used Edson Pull/Pull conduit steering.
I installed it on my C&C Redwing in '87. Still works perfectly.

hello fellow sailors

i am a firm believer that maintenance is key to longevity of boats

my cal cruising 46 has hydraulic steering for both inside and outside steering

WHAT SORT OF MAINTENANCE MUST I DO TO ENSURE GOOD PERFORMANCE?

THANKS IN ADVANCE
