The point being, unless you have gills, you have an air supply. As for hoses, it can branch off your present air supply hose or whatever you use. No need for dragging anything more and air tools are a LOT more compact and efficient than that thing you are touting for 2k. Plus air powers many more tools than just a brush, for getting in crevices or removing barnacles, etc. I'm not the one with narrow vision in this discussion.

Re: The Future Of In-water Hull Cleaning

C'mon guys, it's a neat, efficient system, and I'm glad to see the vid posted here. Unfortunately, where I'm at the underwater visibility is so lousy you couldn't see where you were cleaning.

All the best,

Gary

You don't know anything about the Remora so you can't know the many features that make it superior to what you are suggesting. Hell, because you have never even used pneumatic tools underwater, you don't understand why the system you are advocating would be ineffective, damaging and short-lived, needing constant replacement.

But that doesn't stop you from coming in here and sh*tting all over the thread.

Re: The Future Of In-water Hull Cleaning

This is very impressive. I send the link of video to Sandy who dives bottoms in Huntington, NY for a living and does mine regularly. And any business will invest in equipment and this seems perfectly reasonable. I don't think I would spend the money for all the gear... but a dive operation should and will recover the investment quickly.

Well done!

Re: The Future Of In-water Hull Cleaning

Wow. That there is one boring video. But that is indeed a cool tool. I think I'll stick with the cotton towel though. The guy here uses a hydraulic-driven disc. I recall it is about 12" diameter. Very fast. But two hoses and a big gizmo-factor. One cannot beat the power/mass factor of the business end of a hydraulic tool.

I wonder how he'd feel knowing he could do the job with a hand-held tool as opposed to an $8000 hydraulic system that requires a boat to move.

Re: The Future Of In-water Hull Cleaning

I'll take Fast's word for how much quicker it is. The video didn't make that obvious. I suspect the unit is positively or neutrally buoyant? Holding cordless tools on the hard gets old quickly. Can't tell from the vid if it's as gentle as necessary to avoid removing excess paint?

To make economic sense, one needs to have business they are currently turning away to fill the freed up part of the day, or just value going home earlier. Can't see the DIY making good use of it, but I get why the pro likes it.

Sweet little device but, at $2K it's out of my budget range. For your pro needs it's great. My one concern is how the seals on it's rotating shaft will hold up long term. Rotating shafts underwater (prop shaft) even the dripless ones always seem to leak at some point.

Really? The video is 12 minutes in length and I spotlessly cleaned half of a 39' sailboat in that time. That included getting into my gear at the beginning of the clip and then swimming back to my inflatable after finishing the hull, dropping the Remora off and then swimming the entire length of the boat and starting on the running gear. Maybe you have a different idea of what constitutes "quick" than I do.

The machine weighs about 8 pounds dry. In the water, it is slightly buoyant.

Again, really? Do you see paint being removed in the video? No, you do not. With the proper brush selection and rotation speed, Remora is even gentler to anti fouling paint than cleaning by hand. It certainly provides a more consistent cleaning than doing it by hand.

Not so, and if you were a hull cleaner, you'd know why. This is a very physical job and having a machine take much of the effort out of the work means you aren't putting the wear and tear on your body like you used to. One of my buddies who bought one told me after his first day with it that he just added 10 years to his career.

Of course, there is also an increase in productivity. It's not much of a stretch to say the Remora can add a boat a week to a diver's productivity. At that rate and at our prices (here in the Bay Area), it will pay for itself in less than 6 months. Mine certainly has.

I think the only reason I'm replying is because of the tender responses.

Yes. Really. As you wipe the machine across the surface, it's not obvious how much faster it is. For that matter, there is no way to know, in a film, just how hard the growth was to remove. I have nothing but slime that comes off in a single wipe of any media whatsoever.

Yes. Again Really. There is no way to tell in that video, whether excess paint is being removed. Naturally, it's more than none and less than all. Where exactly is not evident.

I will take your word that it is gentler, which is simply what I asked. Are you taking these questions as critical of you videography? I don't get the tone.

Obviously, you missed my sentence that said I get why the pros like it.
