Generally an excellent design, test and build, from the bottom up.
I used MST Rescue 1000 twin diesel/jet lifeboat for a few years that the RNLI liked so much, they bought it (3), albeit in a modified version.
I think they will make the next ones themselves though, under licence.
Also regularly use an MST Rescue 900 9m RIB, was with 2 x 250, now 2 x 200, very capable & well behaved. Now also used by Maryport & St Abbs independent lifeboats, but they are generally bespoke, and made and sold to likes of MoD Law Enforcement & SAR with a price tag to suit. I don't think many are in private hands, not yet anyway.
They also make Mibs & Sibs, mainly for Defra/SAR type stuff under the SIT Brand.
