NAMJ recently has finished the sea trails in Vigo, Spain on a 11 meter Rib boat with twin TJ-431HH that was built in Norway by Maritime Partner and will be working off the coast of Nigeria.
11-meter rib has 4.4 tons (9,680 pounds) of bollard pull and provides amazing high speed of 31.5 knots with four persons.
NAMJ had to modify the TJ-431HH jets to be able to install into the 22 degree Rib. Below is a 3-D drawing of twin TJ-431HH constructed into a jet pak for this application.
