- Paul Madden introduces new Grant Maugham design for a 250 ft / 76 meter long-range global expedition yacht. This design is based upon the ocean-proven 240 ft OSV which has been one of the most utilized vessels on the offshore supply fleet for more than 25 years.

- 240' C-Carrier and 240' C- Rambler - both built by North American shipyards in 1998 and 1999
- 240' HOS Sweet Water - built in 2009 at Atlantic Marine (now BAE Systems).
Specs for HOS SWEET WATER:
LOA 240'
Beam 54'
Min Draft 8'
ABS Class DP2
Cruise 10 knots, Max 14 knots

As a captain/ DP instructor in Louisiana this is great stuff
Looks like an amazing oppoutunity and design. I'll never be able to afford it but it would be great! My dream would be to fit out one of these with proper submersibles and marine biology labs and do some proper exploring. That vessel was beautifully maintained - those bilges were pristine, credit to her crew!
Humans are amazing, the things they can design and build.
One of the best options I’ve seen🤙🏽 Could you show some interior renderings of what it could look like. BIG UPs from Dallas, Texas and shout out to “ THE BOOT” and our Cajun Guide Mr Pitre…wonder if he is related to some from Lebeau?✌🏽
On Paul's link, ExplorerYachts.com, look under the Explorer Yachts tab and look at the downloadable PDF's.
I just saw a video for a 180’ $65 million dollar yacht. I’m guessing this would be less than half that to have a heavy duty commercial level better boat. Great videos thanks for sharing.
It would likely be less than half that price, as long as the interior wasn't over the top.
That looks amazing
I love this channel, I hope one day I can buy a conversion explorer yacht
I do too!
Great VID Paul...I like what I see.
Thanks 👍
Nice one, great video!
Thanks, Kip
I'd like to see theses guys taking a tour of the ship after the conversion is fully done.
Me too. We have some being done now, so check back.
I enjoy vids.
Glad you like them.
Can you do a video on the ocean king 130
Hello Paul. Let me know if you need some help with the technology. I'm an expert in Marine electronics with years of experience. I Certified by NMEA (National Marine Electronics Association). I'm very familiar with these vessels and the industry. I am been on and done work on many of these vessels. I worked in the Louisiana offshore industry for 30 years. Still doing it.
This looks good.
I'll outline my criteria down below.
1- My first requirement is for the ship to survive the worst possible weather, so ships working in the North Sea or the Southern Ocean would be the obvious choice.
I would have wanted an Ulstein X-bow vessel, but since those aren't very economical, I'd have to settle for the traditional flared-bow vessels. I don't think the axe-bow would survive very deep troughs.
2- My second requirement is for the ship to carry an amphibious aircraft, or, at least carry a a helicopter and a small amphibious vehicle and refuel an amphibious aircraft.
The amphibious aircraft that I want is the Grumman Albatross (96ft X 64ft), so if a ship can economically carry it, fine; or it has to wait till I can afford a ship that can carry it and meanwhile settle for a ship that can only refuel and service it, so it can fly me in and out of the yacht.
I want it to rescue me in emergencies.
3- My 3rd requirement is for the ship to have redundant systems---2 rudders, 2 screws, and two engines or more.
4- My fourth requirement is for it to be the most economical option to survive the worst seas and carry the helicopter and a small amphibious vehicle., so I would it the economy cruise to not cost me more than 60 GPH to 150GPH at 10 knots.
5- My fifth priority would be the interior. I like the Alucia holistically, including the interior, whereas I like the interiors done by San Lorenzo and Lusben, even though they haven't done any yachts with helicopter and amphibious vehicle hangars.
Sounds amazing!
Will it be EMP-shielded?
👍
Why not convert the mud tanks to diesel tanks and add freezer space to be able to increase time at sea?
This can be done. These vessels not only bring mud to the igs, but often have diesel tanks dedicated for transporting fuel- and these are easiest to convert for ship use. In all cases, there is a lot of space available on these for conversion purposes.
What do these cost fully up fitted ?
It really depends how you finish the interior. The basic vessel and systems can be dome for $12-15m.
The wide beam is handy but not everyone is going to need a 250ft yacht,
especially if you can build superstructure on the aft deck. So an option is to cut a section out of the vessel to shorten it. This is greatly facilitated by the engine room being right aft, so you're not cutting into anything vital to the ship.
What cost range we talking about on this conversion?? I definitely would an industrial ship and convert it, all serious machinery
$10-20 million depending on the interior and toys, and things like heli-hangar with refueling.
How much wud a 1988 and a 2008 OSV cost?
Can you give us a ballpark figure how much this will cost?
The commercial hulls can be bought in the $5 mill range (20 years old) and a basic conversion is $15-20m.
what speed are the hulls on the 240
13-15 kn max.
Hmm, if I had the money to convert, I'd leave the bridge where it is. Aesthetics be damned, I want to be well forward, but that's just me, I guess.
How much for fully covered like in video?
Always a tough question. Much depends on the style of the interior. We usually budget $8-10 for a basic conversion.
The cost: Do u take the vessel down to the steel and replace everything new.
Not at all. We look for well-built, and well-maintained vessels. A commercial vessel that is in-class is usually ready to go to sea. The engines are made to be rebuilt and go back to work. Figure that a commercial vessel is designed and built for 40-years hard service, normally.
Do u have any units that have been completed or videos of any units with finished interiors that have sold?
I absolutely would leave the ship as is and build back. Aesthetics be damned, function first. If I ever come into that kind of money, These guys will be my go to for a sourced hull and refitter.
Quick Question. If you do this conversion are not stuck with a very deep draft? Isn't he draft 15 Ft? What if you still want to go and stop off in the Bahamas or Caribbean Island and not get stuck?
Larger OSV's can easily be 15 ft with fuel. They are 10 ft draft when we inspect them laid up, with minimal fuel. Although the conversion adds weight with new accommodations, we are taking off the mud tanks and other extra tanks we don't need. Also coming off are heavy pipes above and below main deck, large pumps, firefighting equipment and piping, and steel cargo railing on main deck. Still, these are not going to access the Bahamas shoals. A fast crew supply vessel with jet-drives would be the best bet for the Bahamas.
If you want to park your yacht next to islands in caribbeans, you don't get a 240ft yacht.
Growth for going into the uncharted areas of the globe. But the 'charted' regions, too big. Bahamas area? Nope.
