    What you're failing to understand or acknowledge, is that the solutions for under 500 GT are VERY POOR solutions. Virtually un-workable solutions into almost any existing design on the smaller end of the yachting world (24-30meters waterline length). I cannot even begin to imagine where/how you could install a MTU 16v2000 IMO tier III into a modern 90' + SF design. It's impossible within the design of what a sportfish is (cockpit starting only a few feet aft of engine, engine room ceiling only inches to a foot above the engine).

    Is it a misguided government regulation - absolutely, 24m LLL seems as arbitrary as anything. Just resigned to looking at opportunities, it will play out starting in 2021 and then we’ll see the verdict. Maybe a grace period for transitioning, probably quite a few hulls being laid up before the year to buy some time.

    24 M is and has been a key size break in European boating. It's involved in licensing as well. In fact, European builders have long built many boats designed to home in just under that threshold and many which would surprise you. So the choice of that size isn't at all surprising, anymore than 500 GT is.

    I believe we'll see as assessment of where the industry is over the next three months and a further extension of time but unlike the previous five year periods no more than a year and maybe only six months at a time.

    24m has been around since at least 1968 if not earlier, back in that day, that was a large craft and the Marine regulation societies knew it was an attractive size to enforce. Didn’t matter if it was a fishing vessel, commercial vessel, passenger vessel and lastly a yacht. Harbors were small and it looked like a dominant vessel.

    Now in today’s world 24m holds less relevance other than the fact that the rule makers collected a lot of data and they can’t seem to fudge their spreadsheets one column over.

    They could have phased this rule in on length or tonnage, starting at 50m or 500GT and scaling it down over time by 10m or 100GT increments. R&D budgets are set in 5 year increments for all the marine companies I have ever worked at, 12 to 6 months extension does very little for the industry, the picture will pretty much remain the same.

    Couldn’t have said it better myself!!!!!

    The cheerleaders have NO idea what their talking about or the sheer carnage this issue has (and still does BTW) wrought upon the trucking industry.

    The maintenance costs and requirements of DEF systems have, in lot of cases, doubled maintenance costs. And the manufacturers STILL aren’t 100% sure of what their doing??!!!!! (13 years later!!!!!)

    Caterpillar left the OTR business directly because of this and Navistar dammed bear went belly up!!!!

    My sons have ten otr trucks and while they've experienced similar problems, just keep, keeping on. What other choices do they have? Try finding old truck engines? We had dual fuel trucks in the 90's - LP and gas. Worked great for a long time until the state told us to stop. I remember Westport doing duals with Cummins. After having operated LNG tug for six months, I'd rather not return to bunker.
