hey buzz,
do you need to move 40 ft of sand or move sand in 40 ft of water, and neither one is easy

 

[Cpt.Buzzkill]

Sorry about that....I meant to get through 40 ft. of water to blow about 5 ft. of sand.

Thanks

Howdy, A couple pics of how one gang blows holes,with about 1200 hp. 8)

 

[Cpt.Buzzkill]

Now that's a kickass rig! Good pics.

The pic of the BIG blowers is on the Ocean Star which we blew a 100 foot wide by 30 foot deep hole in 6 feet of water on the El Salvadore site in NC.But can also blow nice size holes in 60 feet of water.

The next blower is for sale, was on the R/V Deep Venture.Heres the info.

For sale: TREASURE HUNT BOAT MAIL BOX PROP WASH DEFLECTOR - Used on a treasure recovery vessel in the Florida Keys as well as the 1715 Fleet on Florida's Central East Coast - 30 inch aluminum tube elbow heavy durable construction. Removed from the boat after after a hurricane grounded and damaged the boat. We left the transom bracket on the vessel as they have to be custom made for each individual vessel mount. The mail box needs only one bracket re-weld. There is an extension (visible as the round tube atop the mail box assembly) for excavating in deeper water (20 FSW plus). Depending on the vessel power on which it is used, it can excavate a nice hole to bed rock. Buyer responsible for transportation to buyer destination. The cage is to protect divers from injury by propellers. Located in the Central Florida area.$3500.00 We can refit this blower to your vessel for a extra $1600.00 mail me if you are interested in it.

Any idea where the Ocean Star is now?

 

[Salvor6]

I heard it was in Brazil, or somewhere in S. America.

Dang! I could really use that Ocean Star once again. Helluva vessel. Brazil is a long way off!

Figure at least 450 hp a side, twin diesels, minimum 28" props and 30" minimum blower size to move appreciable overburden at that depth.... and the efficacy will be directly proportional to the bottom composition....

Deeper water means bigger screws, more HP, and bigger mailboxes...and longer blow times.


It IS entirely possible to move sand at those depths...just have to use the right setup.

I have often wondered why a blower system couldn't have a 10 to 20 foot extension added to the down portion behind the props. If you added some semi flexible material to join the two pieces that would allow for boat movement. I understand the extension would maybe need an inch or two larger at the bottom.

Harvk there is another similar vessel available for sale. The R/V New World Explorer is a 110' blower boat docked at St. Lucie River: https://www.facebook.com/newworldexplorer/ It has twin 1,200hp MAN diesel engines. It has not moved in over 6 years so it will need some maintenance. You could probably get it cheap.

Enrada my buddy Joe Hines of Tampa had a blower with a canvas extension he used in deep water. He called it an "elephant trunk."

Quite the contrary; The New World Explorer is in fine operational shape, just back from a Navy Charter.

Thanks for the update Capt. Dom. It's good to hear the NWE is back in ship shape. That's a beautiful boat.

Canvas extension, that should be interesting to see... if it works as good, will save a lot on expenses compared to solid extension.

I saw it on Stock Island about two and a half years ago.

Do mailbox blowers work with shallow sand over hard bottom?

 

[agflit]

Yes...

 

[Red_desert]

Yes...

Thought so, thanks!
