Tides and Currents and Wind Basics

Tides Current and Wind Basics

Tides, current and wind basics will introduce you to the essentials to how water moves and how we determine how we move through the water.

Understanding these forces will help you make smarter decisions in planning paddling day and overnight trips in the Pacific Northwest or beyond.

Learning Tides Currents and Wind Basics will prepare you to better learn the hands-on methods of marine navigation.  The next course, Marine Navigation gets into chart work, taking bearings and compass work for crossings, route planning. Much of that require understanding tides and currents and wind first. Getting the bearing for a 4 mile crossing requires ferry angles when current exists.

That means knowing how to read current and intervals to determine crossing bearings and how to adjust them as the current flow will differ in the first and third hours. We use the 50/90 rule for that, which is learned in this class.

You’ll receive a complimentary copy of SBP owner Rob Casey’s book “Kayaking Puget Sound and the San Juans, 60 Trips

“This is a great class – it’s been the foundation of knowledge that I keep adding to, and helped me be comfortable navigating Deception Pass regularly and learn to put theory into practice. Definitely increased my ability to have fun and explore dynamic environs of the coastal PNW. Thanks SBP instructor Robert Nissenbaum”


- Jac H

“Just wanted to say that Robert was an amazing instructor for the T&C class in Anacortes. Glad I signed up!”


- Susan B

“Great class!  Probably one I’d say as a requirement if you’re out on the Sound and don’t have much boating or open water experience.”


- Ariel P

“Today was awesome. I stepped way out of my comfort zone. That’s what took me so long to decide if I was driving or paddling. Once again, I thank the skills and confidence Robert gave me. I still don’t feel I could easily self rescue but where we paddled today I felt that even if I went in, I’d be okay.

6 months ago that wouldn’t have been the case. And I really appreciate your tip on my bent arms. It felt awkward to me, but I definitely felt the difference in power. I will use that next weekend when we paddle our 26 miles of Lake Cushman, so thank you!

- Dnitra A

“I thoroughly enjoyed my class on currents, tides and navigation held at deception pass  this weekend. His attention to detail and patience was thoroughly enjoyable.”

- Susan B

I conquered several fears paddling in currents and surfing waves and owe it to Rob, where safety and professional instructions are Salmon Bay Paddle’s top priorities!

- Margrit Ralph

I’ve been paddling on flat water for about a year and thought I was pretty good.  Then Rob patiently explained how to make my paddling more efficient, how to deal with swells and choppy water and how to be more comfortable and safe on the board.  In one hour, I became a much better paddler.  If SUP is new to you or if you’ve been at it for a while, Rob will help you have more fun on a paddle board.

- Karsten Hagen, Bend

“I wanted to pull two visiting teenage girls out of their comfort zone of shopping, make-up and Netflix. Having personally taken lessons with Rob a couple years ago, I contacted him to see if we could arrange something. Instructor Joe McColskey, a former high school teacher and personal trainer was up to the challenge. The girls really enjoyed their SUP Basics session.”

- Lynn P

“Rob is a fantastic stand up paddle board instructor. His knowledge of the sport and the local waters is remarkable. I’ve been out for a couple of lessons with him now and I’ve learned a lot and become a better paddler each time. I especially appreciate his commitment to safety and doing things the right way. He’s also just a good dude and I highly recommend him to anyone interested in SUP.”

- Shanon Dell, Sequim
