Oh my goodness, think about the consequences first.

Not at all I keep an eye on it around pylons when docking. Its when it is extended I watch for crab traps. If I was to run over one, I go into neutral and pass over the trap with no prop running and the system starts to park . But no clearance problem except for that.

Always manual but it will auto park when in neutral, which is good when you run over a crab trap. You automatically throw the throttle in neutral to stop the prop and at the same time the stabilizer parks.

1/10 to 2/10 knots. I figure about a gallon of gas per 8 hr. cruise.

The angle difference is slight but autopilot corrects. In manual steering you can't tell any difference except for when you deploy it, the MMS will present a noticeable pull to port for the 13 seconds it takes to deploy. Then it smooths out and no more pull. Speed in the water is about 1/10 of a knot. There is a set of shear pins under a bolt cover I can reach easily and replace if I was to hit a channel marker for an example. About 30 minuets and $1.00 in parts. Crab and lobster pots worry me but so far, my procedure when I don't see a pot in time, is to put the throttle in neutral to stop my prop but at the same time the MMS goes into park automatically and if the pot was caught on the arm, it would slip off as it parks.

DMS prides themselves on low maintenance. Very little moving parts compared to a gyro system.

That's a very cool idea. I don't see why that would not work. But we decided this way and I look down at it when looking over the stern and like seeing it to monitor the algae growth. My stern thruster has a guard around it which helps guard the rear area. But your idea is outside of the box thinking. Thanks.

nope hardly any fins are worse

Flopper Stoppers are great for anchoring or mooring if that is your situation. We are full time cruisers and require stabilization on the move. A rolling stone gathers no moss... or in this case, no algae. Besides, we pick our anchorages in calm protected waters to not need a Flopper Stopper.

@@mvmoondance1283 I guess no one told you but Flopper Stoppers do a great job while cruising and for a lot better price than those Dutch thingys !

@@moejaime2654 Paravanes are for moving, flopper stoppers are for at rest. What am I missing?

Flopper Stoppers do both !

1/10 of a knot which is a gallon of fuel for every 13 miles. We travel about 50-60 miles per cruise day. This runs around $20.00 per day extra which is about the cost of an Uber. We find it very much worth the cost. But we are still measuring and will post in our videos more data.

@@mvmoondance1283 Not nearly as much as I would have thought. Thank you for the reply!

It adds 1/10 of a knot drag. I don't consider it a lot for the comfort we get.

No. You need to be moving over 4-5 knots. We travel at 9 knots.

They stay in the marina

As our videos show, we are no stranger to rough seas. The additional stabilizer does not turn our boat into a zero pitch and roll boat. My beer will still spill in rough seas. But it does allow us to go out in larger seas. Increases our weather windows. 5-6 foot head or following seas will still send waves over the deck. Since this is a pleasure craft, my job is to make it as pleasurable as possible for my crew. We choose our weather the best we can but the seas have some level of unpredictability. We have been caught out in waves and storms, battling the elements. 50-60 mph winds and 5 foot waves has all hands working and no free hand to film. I personally love the challenge and excitement but my wife and dog... not so much. It's during these situations we have said we were glad we were in a Nordhavn. Now we can say, : a Nordhavn with a stabilizer".

Be cause most people on sailboats these days don't know enuf to use the sails for steadying.

It's funny how many sailboats we talk to are changing to a trawler. I wounder why?

@@mvmoondance1283 Because they're too old to sail a proper boat

Because it might be what they want. People are allowed to have different goals and ideas. Even if you perceive them to be "wrong" according to your high standard

When you grow up and can buy a boat of your own, you can name her what ever fits YOUR heart.
