Boat Test Review on BoatTest.com

Overview

In this discussion, Christopher Hughes from BoatTest.com interviews Grant Porter, Executive Vice President of Manufacturing and Product Development at Formula, focusing on the Formula 370 model. The conversation highlights Formula's strategic design shift toward day boats that cater to customers seeking high-quality vessels primarily for daytime use and entertaining guests rather than extended cruising or overnight stays.

Design Philosophy and Purpose

Grant Porter explains that Formula has recognized a growing customer base that owns waterfront homes and desires boats optimized for entertaining large groups during the day. To meet these needs, Formula has developed models within their SunSport and SuperSport categories featuring spacious cockpits designed to accommodate many guests comfortably. While these boats include cabins, they are intentionally designed without full standing headroom or live-aboard capabilities, emphasizing their role as day boats rather than cruisers.

Material Selection and Quality

Every design choice in Formula boats serves a specific purpose, reflecting a commitment to quality and durability. For instance, the use of Corian countertops, sourced from DuPont, is a deliberate decision based on extensive testing. Corian's special resin composition offers superior toughness and resistance to cracking or breaking, ensuring that the materials withstand the rigors of boating life. This attention to detail underscores Formula's dedication to delivering lasting quality to their customers.
