**Abstract**

The recreational seaport industry carries out many critical functions, including transport circulation, logistics, commercial, and spatial ones. They influence local economic growth and determine the quality of recreational seaport. However, the definition of recreational seaport quality has remained elusive among the community, at present. Hence, this chapter explores the current literature by using the Systematic Literature Review (SLR) to derive at the definition of seaport quality based on three categories: seaport effectiveness, seaport reliability, and seaport governance, which will be main pillars for the development of marinas. This chapter proposes the Seaport Quality System (SQS) and Spatial Interaction Model (SIM) as a way to develop approaches and strategies that support sustainable planning and management of recreational seaports and marinas in countries with extensive coastlines. It is proposed that in order to offer sustainable and quality services, marinas must adopt the SQS model based on identifying and managing quality and risks. In addition, SIM can be utilised to improve the marinas operations by adopting key components in cruise activities, economic corridors and seaport regionalisation. The combination of both models are essential to enhance the growth momentum of marinas in this country.
