JANUARY 3, 2022
The International Maritime Organization (IMO) had been pushing new Tier III requirements with stringent limits on Nitrous Oxides (NOx) levels in marine diesel engines. While requirements like this have existed for quite a while on commercial and work boats, these new requirements apply to recreational craft with load line lengths over 24m. The recreational craft mandate took place starting January 1, 2021. Selective Catalytic Reduction, or SCR, is the solution for most.
That date caused a stir, especially in the USA, where many builders of large yachts were scrambling to figure out how to fit these not unsubstantial systems in their existing designs. In fact, some owners decided to push forward the start date of their build to being prior to January 1, 2021 – thus meaning the new requirement would not apply to their craft. Jump forward, and while the IMO standard is in place around most parts of the world, the USCG has pushed that date back 3 years to the beginning of 2024 for vessels built and operated here in the US.
So now the clock is ticking again. If the build is started prior to the new date, the vessel does not need the emission control system. Again, these systems require lots of space, significant maintenance, and a supply of urea for the SCR – they are quite costly. Pair this with the relatively short new construction build lines at many of the US yacht yards, and we see that now is a great time to build a yacht in the US. A strong economy, high demand, and ability to not have to meet these new emissions requirements combine to help create a friendly time for those interested in a new mid to large sized yacht, built here in the US.
