No, Seastream is not made by Feelfree. However, both companies are based in Australia and share a similar focus on kayak design and manufacturing. Seastream was founded in 2002 by brothers Andrew and Darren McLean, while Feelfree was established slightly later in 2004 by Tony Pudler. While the two brands have many similarities, they also have some key differences. For instance, Seastream kayaks are designed with a greater emphasis on speed and performance, while Feelfree kayaks tend to be more stable and comfortable for leisurely paddling.
