TP Marine makes extremely strong boats, mostly all of them made for proffesional use.
I have sailed them last month during the Volvo Ocean race.
Very stabil and easy to handle boats with servo steering and throttle.
With or without 14 people on board she took off like a rocket with a single Volvo D6/350hp duoprop turbodiesel.
They are busy making a new model 11.8/3.8 meter with twin diesel setup and with a extreme deepV.
It's a 10 minute walk from the ferrydeparture in IJmuiden
Sure worth making a visit.
