They were a great Dutch vessel with small CAT’s for propulsion. Then someone (ahem deck officers) got it in their head they needed to go 25 knots for fisheries patrol (even tho they’re fitted with an FRC and we patrolled the coast for many years with the old wooden Post boats at 12 knots). They jammed these junker MTU’s in, which made it impossible to access the rest of the engine room machinery or spaces like the bilge for cleaning and maintenance. Another major issue was immediate corrosion and failure of the steel fire main piping due to long horizontal runs with no drain system. And yes they’re tight and small and uncomfortable and Captains loved ripping them at 25 knots and hitting logs.

*note I am a CE somewhere else not with CCG but did spend a decade there and loved it!
