Introducing Rendall Irwin, the old man of the sea. Rendall’s diving style is a slow steady pace with massive air consumption. He likes to give his regulator a full work out and frequently laments on the top side that his air tank is just not big enough. This Triton was first NAUI certified in 1979 and then crossed over to PADI in 2021.

He received his PADI Divemaster certification in 2024. Above all, he loves to help others explore the fascinating world below the surface. With the patience of Job, a safety-first mindset, and a teacher’s heart, his addiction to scuba diving makes him an excellent instructor.  He can show you how scuba really is for everyone regardless of shape, size, or disability. Rendall believes the best dives aren’t rushed—they’re relaxed, well planned, and full of wonder.

Rendall guides divers toward calm buoyancy, efficient breathing, and confident skills. He’s passionate about accessibility and welcomes divers of all shapes, sizes, and abilities. From first fin kicks to refreshing rusty skills, he meets each diver where they are and supports them at their pace.

Expect genuine encouragement, clear briefings, and a watchful buddy who’s always thinking ahead. Whether you’re trying scuba for the first time, polishing fundamentals, or simply looking for a steady leader to show you something new, Rendall makes diving fun, inclusive, and safe.
