Tribune is that a Ribworker ?
Used Boat Show
1 of the companies I work for needs a Ribworker or something very similar i.e Jet Drive, proper engine preferably CAT, Scania or Iveco if singles or if a pair of smaller lumps the I'm not so fussy Yanmars are fine. The budget is realistic if it's a single point lift then the budget is much more realistic.
