So that's how you tack, which takes me to my first question how long does that take? I can see some self tacking systems working OK in casual cruising but a traditional head sail not so much. Maybe I'm missing something I couldn't bring myself to watch the whole video.

I can't wait until a boat so equipped wins a race.
Be a tad embarrassing for the humans eh?

I disagree. Embracing technology does NOT need to be an "all or nothing" proposition. All technology is not automatically "good." There is such a thing as the misapplication of technology and it's a skipper's discretion where and how he chooses to apply technology on his/her own vessel.

Re: Automation

Hmm, I'd say if you like the idea -- buy it.

If you prefer controlling things yourself -- don't buy it.

Hell you can still find people who trash roller furling headsails and bow thrusters, but a helluva lot of sailors use them.

Re: Automation

As Mark said (more or less), all they did was add a remote button to the e-winches. It ain't like the damn thing senses proper sail trim and make adjustments.

I'm not much of a tweeker, sometimes I'm too lazy to do simple adjustments like tighten the vang or the outhaul...maybe this is just what I need...or maybe I'd be too lazy to raise my arm and push the button.

Re: Automation

I do the technology interesting, most of it is in use already, just the position of the controls has been moved to a central control panel. I have seen electric winches and furlers kitted out on boats, nothing new there.

What does bother me though is the automated trim. The last thing I would want on board is something that, while under great pressure, begins moving under its own power unannounced. The last thing I would want is for someone to lose a hand or finger because the winch started grinding on it's own with someones hand inadvertently placed in the way, such as my daughter. The ability to override a failed or malfunctioning part of this system is a concern, such as having the furler winding, and the at the same time the winch is pulling in the opposite direction.

I personally prefer KISS, and would not use the system, for someone else there might be some good value to it, such as physically challenged, but even then if it fails...what then. All things will fail, and usually at the worst moment...that is what we should all be prepared for...

I agree with you. I don't see any sign of redundancy in the controls. If the control panel fails you're grinding. Which is okay, because I'm mostly grinding anyway.

Mine works fine. It's all Mastervolt so everything talks to everything on a CANBUS. Everything is optional, but sometimes it is handy to have the battery monitor tell the generator that the battery bank is down to some level (I use 45%) and run until back up to another configurable level (80% for me). There are lots of auto-start applications in the world -- I think Mastervolt looked well outside the recreational marine market for lessons learned. They have since sold off their generator business so I'm not sure what you can get these days.

I don't run the system regularly. I've used it sitting out hurricanes and leaving the boat for land tours. I've also used it at the dock when the power goes out during winter storms.

I don't think much of bow thrusters at all, but that's just me. And most hydrodynamists.

That was my first reaction. It made me think of dynamic positioning systems on ships. The technology for autotrim would be easier. It's implementing it at a price point that recreational boaters, including those at the top of the market.

Agreed, although most electric and hydraulic systems have individual IN and OUT buttons (pretty robust) instead of a computer control.

Consider elevators. Escalators. Water treatment systems.

I do worry about the shear weight of all the warning labels.

In and out. But this is the much more slick captive sheet winch. You can never gring them afaik


trim up to 12 or 13 meters of line per minute, respectively.
