In this paper, a 4-passenger cost-efficient vessel which can form a new transportation alternative in
Istanbul has been designed. The design process has been progressed within the framework of speed,
flexibility and cost. Detailed route analysis was carried out to understand the necessity for this product for
transportation in Istanbul. Concept design, preliminary design, and cost estimation of the vessel was
carried out to accomplish the objectives.

Keywords: Design, Route analysis

1. Introduction

In our modern world, traffic became a crucial issue for metropolises with the contribution of
population growth and migration. This issue especially shows itself on the land transportation.
Local governments trying to solve this problem with improving and varying land mass
transportation alternatives. However, metropolitan cities commonly have limited space for the
improvements. Therefore, other solutions like subways; trams etc. are becoming logical options.
Another alternative is the usage of sea, canals or lakes for coastal cities. Because some of
metropolitans are generally placed near a sea, river or lake, this fact can be an important
advantage for transportation.

As an example of those metropolitans Istanbul which according to Castrol and TomTom Start-
Stop Index has the first place in the traffic jam list, transportation on water can be an alternative
solution for this problem [1]. Bosporus Strait divides Istanbul into two regions: Europe and
Asia. This allows transportation between two regions vertically and horizontally. Istanbul’s
mass transportation system takes advantage of this opportunity by varisized vessels and many
routes. Unlike the capacity of transportation on water of Istanbul, as Aycı and Barlas stated,
only 2.54 % of passengers choose marine transportation [2]. Additionally, the capacity usage
ratios are around 20% [3]. Mass transportation fail to satisfy passengers’ rapid and flexible trip
expectations and private sea cabs’ prohibitory pricing conception move people away from the
sea. In relation to these facts an alternative transportation is proposed depending on deficiency
of marine transportation in Istanbul. A cost-efficient 4-passenger vessel was designed based on
the mentioned criteria.
