A key factor for the safety of diving operations is correct risk assessment. This workshop focuses on identifying, mitigating, and managing risks derived from divers’ actions and interactions with the environment. Most of the diving mishaps originated not from a single step but rather from a chain of interconnected events. Interrupting even one of such events prevents escalating the problems. A good knowledge of the potential environmental hazards is also needed to develop a safe and proficient diving plan. Finally, the components of the diving team should be carefully chosen to create a synergic interaction that enhances the team's efficiency. At the end of the workshop, you will have learned:•    How to identify and manage realistic risks associated with diving operations.•    How to critically analyze diving problems and learn from them.•    How to enhance diving team safety and proficiency.•    How to develop a sound and safe diving plan.

Attendance will include a signed copy of my book “Risk Management for Diving Operations” (a value of $39.00).

The PADI Member Forum 2026 is packed with the most up-to-date information on risk management, training, marketing, new programs and products. It is not only an interesting meeting, but you will also find inspiration for your lessons.  It will be hosted by the regional manager Josh Childress your PADI team. This is also the time to ask your questions and connect with us live again.   The registration for the PADI Member Forum is free of charge.

In this workshop, Tec will present the top ten mistakes that divers make. As a dive training agency director and a forensic dive accident investigator, he has seen the unfortunate outcomes of these mistakes. The consequences range from dropping out of the sport, all the way to serious injuries or even death. This workshop will present a selection of mistakes. Tec has seen divers make over his 27-year career as a diving professional, and these are errors that he stresses to his students not to do. Some of the items you may think are cliché’d or something you do not do wrong – but keep reading. He will teach you how to avoid these mistakes and even improve in areas that you may not think you are doing wrong. He will go into detail in each area, bringing unconventional wisdom and rationale into each lesson to prevent these mistakes from occurring.

Are you stuck in a rut or lacking creativity whenever you shoot macro?! Join us as we show our tips and tricks to get extraordinary results with your macro photography. We'll cover our favorite lighting techniques, on camera and off camera snooting, making creative backgrounds, and more! 

The Masking and Selection tools in the Develop Module have taken a quantum leap that greatly expands their power. The ability to add, subtract, combine, and invert complex selections has made this little old sorceress very happy, and I think you’ll feel all tingly too when you join us for this deep dive into Masking in Lightroom Classic. You want this!

Photoshop. It’s adored and feared. It’s canonized and maligned. It is, above all else, de rigueur for underwater photographers who’ve hit the wall with their editing in Lightroom. But words like Layers, Layer Masks, and Selections are enough to send many aspiring editors into a vertiginous spin. Never fear. Behind the complex interface, overwhelming array of tools, and terrifyingly complicated techniques are a few very simple concepts that will absolutely save your bacon and your photos! Shatter the limits of Lightroom and be free!

Are you an underwater photographer who dabbles in video, but doesn't have an easy and efficient way to take your favorite clips and transform them into an amazing edited video you can share with your friends and family? Join this video editing power session to learn the ins and outs of DaVinci Resolve (Free Edition). The software is FREE and works on Mac OS or Windows. This is not a work-along session, but if you’d like to look at the software during class, please download DaVinci Resolve before attending. All video editing software can be daunting to use.

Lightroom is incredibly powerful, but it’s no match for the Dark Arts in Photoshop. Abracadabra! Backscatter disappears like magic, the crop tool creates extra space and fills it in perfectly, and divers appear – elegantly posed – to populate every empty composition. Add Artificial Intelligence to the mix and things get really dirty – in fantastic, addictive, and insanely useful ways. Learn how to channel Photoshop’s wicked superpowers for good and of course for a little bit of evil too!

NAUI Workshop Series Boston Sea Rovers International Ocean Clinic

1:00 – 1:45 – “Blending of Breathing Gases” 

Presenter - Mark Criasia 

Abstract: 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.

3:00 – 3:45 – “The Power of Breathing Simply - A Diver's Exploration of Breath” 

Presenters - Kreig Pinkham & Jeannine Russell 

Abstract: 

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. 

Kreig Pinkham is the NAUI Technical Instructor and Training Director at Waterfront Diving Center and holds a master’s degree in religion with a focus on comparative mythologies.  Jeannine Russell is the Archeology Officer for the Vermont Agency of Transportation and a NAUI Assistant Instructor.  Together they promote the development of diving in Lake Champlain as the principal organizers behind the Waterfront Diving Center’s community events calendar.

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.

Dive Computers - nearly all divers carry one, but does everyone really understand how they work and how to properly use them?  In this workshop, Dive Pro Monty Fitzpatrick will walk you through a brief history of the dive computer, and give an overview about how they "know" how much dive time you have left, and what your nitrogen loading is throughout your dive.  We won't dive too deep into the algorithms behind most dive computers, as that's more technical than this workshop intends to go.  But we will cover some of the basics:

• Why to use a computer vs. old-school dive tables
• How to decide which computer is best for the diving you plan to do
• Key features to look for in your computer
• Console-integrated units vs. wrist-mount options
• Air integration - its benefits and limitations
• Popular models that are available at most dive shops
• Understanding the important features and data shown on your computer
• Maintenance and care for your computer

Whether you're a brand new diver or have been salty for years, there's something to be learned about these little devices we've become so accustomed to wearing to dive.  Whether it's understanding how to simply use your computer, or interesting functions you didn't realize your unit included, you'll benefit from attending this workshop.  We will have an extensive Q&A session; feel free to bring your computer.  We may not be able to answer every question about every computer, but we'll do our best to make sure you're more confident and comfortable with yours before you leave.
