I spoke with them and they said they have emailed you back at least twice, maybe check your spam folder.
Yes, i had one of my owners use it last week and gave it high reviews, held great in 20-25mph winds

Thanks Dan. They reached out to me with a message here. The other "Ryan" they were corresponding with wasn't me, so not sure how my inquiry was lost, but immaterial since I'm in touch now. I appreciate you reaching out.

Dan,
I looked at their website -- novel idea -- what do the large ones cost -- I could not find any pricing on their website which I always question.
Thanks

Prices are on their site, click on the top orange banner and that takes you to their pricing. Our boat, 73' X 16' only needed 2 large ones and they also used one of the smaller ones for the bow for the "just in case"
 
All prices I saw were for rental -- that would not interest me. Do you know if they sell the bags outright-- did some quick looking, and looks like you can get similar made, but I would want to reward those that came up with the idea -- if they sell them. Thanks!
 
I also want to see how they hold up in some heave winds, I am a little leery they wouldn't be pulled into the water when the wind come blowing thru?? And then once in the water, how do you release the houseboat from them, you can't untie, the bladder would sink. Just some of my thoughts.......
 
If I do some quick calculations --- very basic -- I am NOT a engineer --
wind force @ 40 mph on flat surface is approx. 5.5 lbs per sq foot --- if your house boat has a side surface area of 480 sq feet ( 60 feet long of surface X 8 feet high) the total wind load would be 2640 pounds of force --- their largest bag looks to be 1000gallons -- fill that with water and that would weigh about 8300 pounds -- sounds like plenty of holding power.

now all you engineers let me know how much I am wrong by---

I've seen a 95' houseboat bend a 1.25" steel rod that's dropped 2 feet into the sandstone. You can begin to see why sand anchors or water bags aren't enough, at least for the bigger boats.

Well if you do the math wind force is .00256×v²=psf then multiply the length of your boat by the height, and you get your wind force. To be on the safe side for a single store houseboat lets say its 10 high and 95 long which is 950 sq ft. Now plug in your windspeeds and you would see you would need 65 mph winds to match wind force to the weight of the anchor, 8,300 lbs, which still wouldn't drag it due to friction.

The depth of the rod doesn't change how much force it takes to bend the rod and i have to ask how much of that rod is above the rock and how far up the rod do you attach your lines?

Put 25' high into the calcs. And I couldn't find a great photo, but here is what the pins look like:

These in the sand I wonder if they would work. Loose med sand to very dense sand are 2000-9000 lb pullout strength straight up. I wonder if they were slanted and in what it would be compared to a buried anchor. At 100 per for the biggest, reusable and 60seconds with cordless impact 3 to a side if you were worried.

I have a sand spike I use for my bow line and am impressed with how well it holds but would never trust it as one of my stern anchors....
 
I was at Wahweap this last week. We were at the gas station at the top of the launch ramp. I noticed that the graphic on the store front showed pinning. I wondered to myself if they realized they were condoning an illegal practice? Why would they essentially advertise that practice? I think the issue needs to be resolved by enforcement or remove the restriction. I am also against designated areas on the lake. This amounts to more restrictions. I much prefer a service that would go out and place moorings under the water for these larger houseboats no more than 1 day in advance AND so long as no one else is already set up in that location. These moorings are then to be removed the day of departure. No buoys, no pinning and nothing visible. It is a disingenuous argument that "I need to pin because my houseboat is too big". If you have the money for one of those large boats, I would think you should be a little more cranial powered to understand what you are getting yourself into. But, I guess ignorance is bliss and allowable if you have those kinds of dollars.

Why not just place the moorings permanently and rent them out???

Agreed.

Probably many of us are familiar with the use of mooring balls in places like the Caribbean and South Seas. Without ready beach access it is less attractive than pulling up onto the beach, but it is very secure and easy to hook up for just a day or two. So, it seems like mooring balls would be popular for the big boats that now use pinning and for those who want to change location every day or two, like cruisers.

There is a nice reservation app, Boatyball, that could be used at Lake Powell.

We'd need policies to prohibit the big boats from paying the fee for permanent anchorage on a mooring ball in a nice spot, only using the boat once a month, but tying up the prime real estate for an entire season. I can think of several options for removing this possibility.

I'm not sure how those on a mooring ball would secure their sport boats. Those of you on a mooring ball at one of the Lake Powell marinas, how do you handle this?
 
The NPS already has their hands full managing the navigational buoys and other items on the lake. I do not see them successfully managing a mooring field spread across the lake, they are already spread to thin as clearly explained in this thread. Unlike the ocean, Powell also has fluctuating lake levels as well as an unpredictable lake bed. In my years at powell the holes have not really bothered me because you do not see them until you get close, but mooring buoys in each cove would certainly be an eyesore.

1. Sound like an business opportunity
2. All the morning balls may slow down the wave serf boats ... ;)

When we were on the buoy we either tied the speedboat to the back swim deck or to the side of the houseboat
