NAUI Workshops & Dive Safety Talks at Boston Sea Rovers 2026 | Avelo, DPV, Mixed Gas & Conservation
NAUI is proud to bring a full lineup of educational talks and hands-on workshops to the 2026 Boston Sea Rovers Show. Designed for recreational, technical, and professional divers alike, this program brings together industry experts, experienced instructors, and conservation leaders to share practical knowledge that enhances safety, skills, and confidence in the water. From emerging dive technology and gas blending to breath control, dive safety, marine stewardship, and Diver Propulsion Vehicle orientation, these sessions offer something valuable for divers at every stage of their journey.

12 PM - Avelo Explained: Why Avelo changes everything
Presented by: Brian A. Verkaart
Curious why the diving world is talking about Avelo? In this session, we break down the Avelo System from physics to practice. See how adding water, rather than air, creates stable neutral buoyancy that stays constant regardless of depth changes, reducing task load and improving safety. Explore the design of the Hydrotank and Jetpack to learn why the weight savings, an average of 30 pounds (13.6 kg), make entries, exits, and surface swims easier. We will also show how Avelo Mode on Shearwater and Scubapro computers uses gas tracking and buoyancy analytics to help divers refine their technique on every dive. Whether you teach new students, create images, or are an expert diver, see how Avelo can enhance safety, extend bottom time, and elevate the entire dive experience.
1 PM - Blending of Breathing Gases
Presented by: Mark Criasia
Mixed gas blending for scuba divers creates breathing gases like Nitrox (more oxygen) for longer dives or Trimix/Heliox (oxygen, nitrogen, and helium) for deep technical dives, reducing narcosis and allowing deeper exploration. Blending involves safely mixing pure gases (Oxygen, Helium, Air) using methods like partial pressure, requiring specialized equipment, training, and analysis (e.g., with a dual-sensor analyzer) to ensure correct composition for depth, managing risks like oxygen toxicity.
2 PM - Recreational Dive Safety
Presented by: Heison Chak
This session examines the leading triggers identified in DAN accident analyses and translates them into practical steps divers can take to reduce risk. We’ll explore common patterns behind incidents, highlight simple countermeasures that strengthen decision-making and situational awareness, and outline how small habits can significantly improve safety on every dive.
3 PM - The Power of Breathing Simply - A Diver's Exploration of Breath
Presented by: Kreig Pinkham & Jeannine Russell
In this interactive workshop we’re going to take a moment to catch our breath and dive into the respiratory system from a diver’s perspective. We’ll examine how one complex system unlocks the key to buoyancy, controlling our state of mind, and maintaining basic life functions. Additionally, we will explore some simple breathing exercises that can be used to enhance your breath, including diaphragmatic breathing, square breathing, and other forms of yogic breath control. Finally, we’ll introduce the 5 Tibetan Rites – an ancient series of stretches that can easily be incorporated into your daily fitness routine to stretch your chest and improve lung capacity and resiliency.
For full participation, loose-fitting clothing and a yoga mat or hotel towel will be helpful.
4 PM - Beverly’s Ghost Gear Challenge: A Winter Recovery Mission
Presented by: Capt. Peter Dickman, Beverly Harbormaster
Lobstering has shaped the North Shore for centuries, transforming lobster from “poor man’s food” into a valuable commercial fishery and a core part of the region’s maritime heritage. As fishing gear evolved from wood to long-lasting wire, new challenges emerged. Lost or abandoned lobster traps can persist on the seafloor for decades, continuing to capture marine life in a process called ghost fishing. This derelict gear harms habitat, affects fisheries, and is a growing concern in harbors worldwide.
Harbormaster Peter Dickman will explain how recent changes in maritime law have made it possible for coastal communities to address this issue and will present plans for the Beverly Harbor Derelict Trap Recovery Project. Funded through a Fishing Trap Removal Assessment and Prevention program grant from the Virginia Institute of Marine Science, the project will use scuba-based recovery operations over two winter periods to locate, remove, and document abandoned traps, improve marine habitat, and support sustainable reuse or recycling of recovered materials. Learn about this collaborative effort to protect marine life, support sustainable fishing, and honor the working waterfront tradition.
NAUI Diver Propulsion Vehicle (DPV) Workshop
Saturday March 14th 5:00 – 6:00pm – Diver Propulsion Vehicle Workshop / DPV Overview – DPV Overview discussion is open to all
Sunday March 15th 8:00am – 12:00pm – Diver Propulsion Vehicle Pool / In-water Workshop – DPV pool demo fee $45.00
Led by: Heison Chak & David Caldwell
Workshop Description: Diver Propulsion Vehicle workshop provides an introduction and familiarization with DPV equipment, basic handling concepts, and core safety considerations in a shallow, controlled environment. The focus is on orientation, ergonomics, awareness, and procedural understanding rather than operational proficiency. This workshop is not a certification course, does not confer open-water DPV competency, and does not replace formal DPV training conducted in appropriate open-water conditions.
Maximum Participants: 8
(Participants need to be able to meet the equipment requirements, see below)
