Yachts over 24 meters required to meet IMO TIER III engine emissions next year.

Do you not realize all of the big Euro builders in this size have the exact same issues? Kind of hard to scrap a design you dumped $18 million dollars in R+D on. I know of several manufacturers pulling out of that size segment for next year, because they simply can't make existing designs that they have dumped Millions of dollars on, work.

Viking is not the only yacht builder rallying efforts for an extension of the Tier III emissions regulations for smaller yachts. Another of Bluewater’s brand partners, Princess Yachts in Plymouth, England is also working to maintain viability of their larger yachts including the ‘M’ and all-new ‘X’ series. Several more European superyacht builders are also standing alongside Princess and Viking in this effort including Ferretti Group, Overmarine, Monte Carlo Yachts, Sanlorenzo Yachts and Sunseeker.

IMO Tier III standards have already been in force for over four years on larger superyachts and commercial vessels that exceed 500 gross tons. The smaller yacht segment of 90-150′ was initially spared from the regulations and given a 5-year window to work on compliance measures. In 2016, it was believed that exhaust treatment systems would become more advanced, even to the point of being integrated into the engines. However, the technology is not there yet and simply won’t be ready by the January 2021 deadline."

OK, so you and pacblue, HOW DO YOU PLAN ON REFILLING THE DEF TANK????????? Have either you or Pacblue thought of that on a sub 150' yacht that can only carry so many gallons (plus it has a shelf life of 6 months). Any tankage on a 120' or under, planing MY or SF is going to be in place of existing fuel or water capacity. So let's say you have a 1500 gallon DEF tank in a 90' MY or 95' SF, you're only going to have a range of 500-1000NM's maximum on the DEF tank. So WHERE and HOW do you refill it? Do you take a day off every other day of cruising and have a vendor deliver the DEF in 5 gallon buckets at a marina you may make it to, have your crew cart 200-300 5 gallon buckets down the dock and somehow miraculously spend the entire day pumping/pouring it into the DEF tank? Then what do you do with all of the buckets or barrels? What marina's are going to install stainless steel DEF tanks and stainless steel pipes and run them to the fuel dock at the tune of $100,000 or more to fuel what, maybe 4-10 yachts per year with DEF? What about running the boat to the Bahamas and spending more than a week, what about the Carribbean???? On a 150' and above, you have the tankage and range and can have a semi fuel trailer of it shipped to you, or meet you at a commercial port, but how do you figure this is going to work on a 90-120' yacht that does not have that option? It's not, it's not feasable, and not an option. I haven't noticed any Flying J truck stops on the water.

DEF fluid is nothing more than the same snake oil that Ethanol is. Does it clean up emissions a little yes, but at what cost???? The carbon footprint to manufacture it and transport it, is far higher than the emissions it would save on yachts. Also, you lose 10-20% fuel efficiency, so burning more fuel per mile.

Now, you have all of these builders who have spent huge R+D money into 90-120' yachts and there is simply nowhere to fit the catalytic converters, the DEF tank, or the weight of the system in existing builds, and nobody spending R+D money to try to design a new yacht to install this flawed system into.

Viking has produced 5 92' Sportfish per year of the 92' since 2015, they're on hull 22 now, and I am not sure how many 93' Motoryachts per year, so yes, I can see them laying off 300 employees due to this IF they're doing that kind of volume. A lot of different builders aside from Viking, are simply getting out of building 90-120' and that will have large ramifications in the yachting industry. THERE IS NO SOLUTION currently on planing yachts in the 90'-120' size range.

No fuel docks are going to be stocking DEF fluid for a very long time. The demand just isn't there. SO for a SF going to the far Bahamas to fish for 3 months do you fill the cockpit with 55 gallon drums of DEF that's going to rot in 6 months? The demand will be so little for it, I don't forsee fuel docks ever stocking it, except for a few. A lot different than the OTR trucking industry.

There were plenty of studies on Ethanol too, and it's still being crammed down everyone's throats, but when you look at the real studies on it, just producing ethanol creates a larger carbon footprint.
