DMS Install Photos

I put together an album showing some photos from the DMS stabilizer install. Pictures are shown in reverse order in the album.

I still haven't been out in burly weather to test it. Will post video when I do.

Cheers

Beautiful install and pictures! Can't wait to hear your performance results. These work at anchor too, correct?

Did you install a single rotor, or one on each side?

It’s a single.

NSM, thanks for the MM single rotor install photos. My 46 should be in the CSR yard in June for the twin rotor install. I'm planning to publish the install photos as soon as they are available.

Slick! Very nice.

Here are a few images of the installation of a single rotor on our H38S.

Sorry but the photo of the unit with the rotor isn't from our boat, it was from NSM's. Scott sent it to me to indicate the location of a deflector we were putting forward of the rotor. Apologies. I don't seem to have a photo of the installed rotor. This shows the location relative to the transom, as our is farther forward, in front of the engine room bulkhead rather than in the lazarette. It won't extend to the transom when parked.

I'll be interested to hear how the asymmetric drag from a single rotor impact how the boat steers. I know with fins if they are not adjusted to have the same neutral (zero deflection) position they will create asymmetric drag and it impacts steering, sometimes significantly.

I feel it when deployed and with autopilot off. But that’s a rare combination for me so haven’t really noticed it when cruising.

I would like to know more of the "deflector". Intended to deflect trap warps? (crab n lobster traps)

DMS said that the vulnerable part was the knuckle where the rotation occurs. The deflector we mounted was basically a clamshell shape about 4" high just forward of the unit. The concern was small log strikes. It'd bounce stuff to one side or the other or over the rotor itself. Nothing can be done when it's deployed though, and that's when it will be most vulnerable rather like a fin would be. Crab lines would not have anything to snag on in the parked position, and if the line is that close to the keel the prop tangle would be of greater concern. We have a trolling valve, so when in trap fields we can be a bit less bull-in-a-china-shop-ish, since idle speed is around 4kt and taking her in and out of gear is herky-jerky.
