Well it's back in but with substantial isolation valves in case it leaks again.

Its a 3ym30 the water heats very quickly but it's also 50kg extra weight. We have a shower but the heads compartment has a lot of nice teak detailing not one of your modern grp jobs. Not sure it would stand regular use of the shower. Also we're not sailing where we can fill tanks regularly so...

My calorifier recently leaked. It's fixed now but wondering If its really worth refitting. It's a lot of extra weight and complexity. We sail a lot but never use marinas. Its usually only luke warm in the mornings. Was just wondering If a kettle now and again would be a better option. Anyone...

I didn't think the camping gaz bottles were very safe. Had a new one and it was difficult to get the valve to seal.

Having converted to self fill camping gaz I was pondering whether to go back to Calor. What are others doing.

Actually the main light switch is relatively easy it's bottom left. I can reach it from the cockpit but don't really want to have to put the cabin lights on when night sailing. I can find most by feel but it would be nice to have some suitable dim lighting.

Looking for ideas to help me find the right switch when I tumble down the companion way after a night in the pub. Probably not PIR, timed off, dim, touch panel, voice activated maybe?

What course computer are you using. I dedided I didnt want to overload the ST4000 so have knocked up a couple if relays to drive the ram. Dont really need that much thrust. Its a pity to have to do that. I was wondering if there's some way of limiting the current draw instead. It's just a trial...

Thats surprising. I was measuring the current the ram would draw. It was definatly 1.4 Amps just extending the pushrod on the bench with no load. I couldn't see how it could be less at sea. The meter is correct.

Just measured peak load at 8 Amps 1.4 Amps no load. Peak current on Autohelm ram when stalled is 4 Amps 600ma no load. I'm thinking it will be unwise to use this with the ST4000.

What about peak current?

Thanks Pcnautic. It seems a well made unit. Nice and smooth on the bench tests. I particularly like the limit switches. Looking forward to sea trials.

Thanks for the link. Yes I'll measure it. The unit is supposed to be a direct replacement for the Autohelm but the motor looks massive. Maybe there's some added electronics to limit the current draw.

I'm just about to replace the tiller actuator on my ST4000 with Pcnautic unit. Will wiring in the rudder position transducer make much difference to control accuracy. The old actuator had no rudder position feed back and seemed to work OK. Second question the Pcnautic unit has a much bigger...

I built a grp spray hood several years ago. The perspex windows were glued on. It's very simple and has worked perfectly. The key thing is to use a thin strip of foam rubber between the two surfaces. This allows a controlled adhesive thickness for differential expansion. There are plenty of...
