Extensive Upgrades done in 2014
Items done at Marine Group Boat Works (MGBW) in San Diego:
1. Stabilizers: Two new 26/21,000 lb. Seakeepers (gyro stabilizers) installed, independent from each other. Note that the previous fin-based Naiad system has been overhauled by Naiad and was left in for redundancy (now ROSA has 3 independent stabilization systems). Installation was done at MGBW
2. Thanks to the Seakeepers Zero speed, ROSA is perhaps the most laterally stable yacht we have ever been on; the total capacity of these Seakeepers is factory recommended for a boat of a much bigger size. Specifically, each of these large units is designed for boats in the 80'-100’ range; ROSA has two of them installed. Even with only one gyro stabilizer unit running, which is all that is necessary in any but rough seas, ROSA practically does not have any lateral roll. This was a substantial investment but definitely worth it. Moreover, it is estimated that the drag of traditional fin-based stabilizers accounts for 10% of fuel consumption underway (source: Nordhavn 120 data); for ROSA that drag is nonexistent and Seakeepers use only 800W)
3. A new bulbous bow installed (designed by Patrick Bray); ROSA has now LOL=LOA=90’.
4. A set of bi-foils (fins) installed under propellers and rudders (with reinforced skegs) for shallow water propeller protection and additionally increased longitudinal stability.
5. Remounting all the engines (new cushion systems designed specifically for ROSA by Soundown - installed to further control noise and vibration).
6. Also, remounting all exhaust lines to limit transfer of noise and vibration to the hull. New, extra-padded cover on the (one) legacy CAT generator (left for additional redundancy as the 3rd generator on ROSA) and padding of all exhaust lines.
7. The top (boat) deck extended aft by 15 ft. to cover the master cabin deck. Now ROSA is one of the few yachts with a large, private, covered deck accessible directly from the Master.
8. The boat deck widened on both sides all the way to the bow to cover the side walkways.
9. Upper deck rails around master deck replaced by solid bulwark.
All rails on ROSA replaced with polished but maintenance free aluminum
A brand-new Steelhead 5,000 lb. crane installed (+ with structural enhancements).
12. A utility Zodiac Bayrunner 14’ (50 hp Yamaha); jet ski (Yamaha Cruiser, 175 hp)
Two new, quiet, fuel-efficient Northern Lights generators installed (55 kW and 38 kW); the third (legacy) generator - a CAT, 60 kW was left in for extra redundancy – surveyed, serviced (perfect compression, etc.).
14. The two CAT 3406 mains have been overhauled and zero-timed in 2012, and thoroughly surveyed and serviced in 2014; they are quiet, especially after rehanging, and very fuel-efficient.
15. A brand new fire suppression system installed.
16. Pantograph transom door and stairs to dive shop and new dive shop arrangements installed.
17. Line cutters on shafts and stabilizer fins. 18. Extra 20k lb. of lead ballast installed down below for increased comfort and stability, still can supplement it with water ballast and trim as needed.
19. All tanks overhauled; grey, black, and fresh water tanks resurfaced, any even slight signs of in-tank corrosion on walls replaced.
20. Ultrasound test of the entire hull, did not reveal any (even residual) hull corrosion.
21. All new seacocks.
22. $150k+ of new electronics upgrades (e.g., a forward looking sonar installation with a 3D display, a new NMEA2000 system, accessible from smart phones remotely).
23. A $150k+ Internet dish with a network, remotely accessible 18-camera system, new sat phone system in all cabins.
24. Not only all cameras, but also all boat systems and diagnostics can be accessed via satellite on any cell phone.
25. Flow-scans on all 5 engines (all networked via NMEA200, and Internet enabled)
26. EXTERIOR ALL REDONE. A major makeover of the entire exterior; the entire boat was stripped down from top to bottom, primed and repainted (all work done in the US – at MGBW in San Diego).
27. All decks have been completely redone with new base and completely new teak on all decks (done and warrantied by Teak Deck Systems, Inc.).
28. Powder coated rails replaced by polished (coated and practically maintenance-free, as shown after an 8 month test).
29. All door lock hardware, hinges, etc., replaced or overhauled and re-polished, etc.
30. A major overhaul of the entire AC system (Marine Air triple chiller installed in 2012, all exchangers replaced as needed; all ducts redone and lines reinsulated, 2014).
31. INTERIOR ALL REDONE. A major makeover of the entire interior: All carpet floors replaced by Brazilian jatoba floors, new furniture, appointments, two side rails on all stairs inside and outside; remote electric blinds, all lighting changed to dimmable LED’s, improvements to the plumbing, water heating, fixtures. New upholstery throughout (distressed) leather on all seats and settees, “1920-style” nonglossy décor throughout ROSA. All new TV’s (4k), refrigerators, freezers, new arrangement in crew quarters, upgraded all mattresses, and more.
32. 2nd master bathroom with external access door and Calcutta Sepia marble.
33. Carbon fiber gangway.
34. Countless, countless other enhancements. 34. New AC compressors August 12, 2015
