I’m thinking of buying a Rutland 913 fairly soon. It’s been a toss-up between the D400 & the R.913, & as I’m thinking of installing it right out of the way at the top of the Mizzen-mast on a custom-built support bracket riveted somewhere about 300-400mm down from the mast-head, I decided the D400 was just too heavy, @ 18Kgs.The R913 is only 10kgs. Anyone else got one, & where is it mounted.? I don’t want to mount it in the aft-deck area as it’s already cluttered with not much room for me to move around.Hi Jeff, We’ve got a Rutland 913, had it for five years now and are very happy with it. It’s mounted on the mizzen on a custom mount I designed myself, just above the spreaders. It works well at low wind speeds compared to other generators and is the quietest generator we know of. We have had no problems with vibration. If you do mount one on the mizzen make sure you can climb up the mast to snub it during very strong winds. We have put a few mast steps on the mizzen to aid with this. We have not had positive experiences with the Marlec HRDX controller and would recommend their bog standard regulator. Best Wishes ..

Hi Peter,Thanks for that.Mike Bennett had just mailed me to tell me that he thought you had one, so I was looking forward to hearing from you. Would you be able to take some pic’s of the mount for me, with approximate dimensions. I’m already having a local Co’ make up a 2nd bow anchor arrangement & I was going to have him look at the Mizzen-mast with an idea to make something out of 5mm alloy or 4mm St/steel, with the cheek-plates on the Mizzen extending forward (so that halyards can pass through) & a substantial base-plate to take something like a 600mm pipe that Marlec supply with it, & then the R913 mounted on top of that, well clear of the mast-head. I realise it’s going to look a bit odd up there but at least it would pick up any breeze that was around.What’s yours made of Peter & did you rivet it or use self-tappers.?Another thing that occurs to me is, if yours is not mounted at the top of the Mizzen how does it revolve through 360 degrees.?How many rivets/screws did you use & is it still all solid after 5 yrs.? I’d think a ‘long’ mast fixing bracket would be ideal, as the wall thickness of the mast is only about 3-4mm so you’d want to spread the load over as big an area as possible.?
over as big an area as possible.? I’ve riveted steps onto both masts so I can work on anything up there now.Regards…JeffHi Jeff,
You have described almost exactly what I built. It’s a piece of 4mm stainless 100mm by about 2000mm, bent into a narrow U shape with the open ends formed to make cheekplates on the mast. The length of s/s pipe provided by Marlec is welded into the other end with a smaller s/s pipe coming down to another cheek plate on the front of the mast. The whole thing is attached with 5mm monel pop rivets. It stands forward of the mast sufficient to allow rotation through 360 degrees.
To date it has proved solid, so much so that I use it as steps when climbing the mast.
