Abstract:
This paper aims to determinethe correlation of power propulsion to hull-forms  parametric  of  twin-propulsion  Tugboats.  By  using  the  regression method, an analysis of the technical data of existing tugboat is carried out, where  the  data  is  obtained  by  collecting dataon  Tugboats  that are registeredand operation as many as 381 tugboats. From the results of the analysiswascarried  out,  it  was  found  that  the  relations  model  power propulsion  to  hull-forms  parametric, thenthe  model  was  validated  by testing  the  existing  tugboat  to  determine  how  many  errors  the  relations model. Based on the results of the analysis carried out, power propulsion affectsthe hull forms parametric, where the increase in power propulsion will  increase  the  value  of  the  hull  forms  parametric  in  this  case  main dimension of the tugboat (L, B, D and T). The value of power propulsion to main dimension of tugboat has a different effect on each type of tugboat.
