Intensive 3-Day Marine Weather Course
with Lee Chesneau
Monday thru Wednesday, April 3-5, 2017, from 8:30 a.m. to 4:30 p.m. $295
This course will integrate interactive lecture and hands-on exercises over an intensive 3-day period. It will begin with the 101 building blocks of weather basics (necessary because of the nature of physical science that is 100 percent knowledge based), then moving onto the various core marine oriented weather products from graphics, alpha-numeric text, to voice broadcasts.
There is the need to view different scales of weather from global to local, where in between is the more dominate synoptic scale (e.g.,the north Pacific Ocean whether regional or full ocean, where the time frame extends from days or weeks) and its influences on more local marine weather conditions of the Pacific NW (Salish Sea) including the coastal waters ranging from SE Alaska through the US West coast including Vancouver Island where the time frame extends from a few hours to a day.
Another way of summarizing, the synoptic scale weather that include weather systems such as low and high pressure, and their features such as fronts, troughs, and ridges that span from two days to more than a weeks will dictate weather conditions (clouds, propitiation, fog, and wind) from what one sees from a boat’s wheelhouse that last from hours or a day, that can be repeated over and over again.
Whether one is a novice, experienced boater, or racer who sails or cruises the inland waters (Salish Sea), the Pacific Northwest coast (BC, WA, OR, CA), as well as further offshore into the high seas waters of the North Pacific Ocean (this can apply to any other ocean, including the southern ocean), there is only one way to strategize the marine environment: understand it.
After an introduction & overview of the three-day course, specific topics will cover:
- A discussion of some important definitions; weather (WX), climate, and the atmosphere.
- A brief review of the different layers of the atmosphere, focusing on the layer where most weather occurs.
- A discussion of the role of the sun and radiation in generating the land and sea temperature difference, the primary cause of both sea and land breezes, both from large global scale to local or microscale.
- A discussion of moisture in the atmosphere and its unique role in cloud formation and other visibility restricting conditions such as fog or precipitation.
- An overview of the importance of atmospheric stability and its significance to clouds and overall weather conditions.
- The different cloud groups and types, and what they mean to a mariner.
- A discussion of basic concepts of pressure and wind, and how they work to develop and deliver common low and high-pressure systems at sea-level (surface pressure).
- We then will look at scales of WX systems from global, synoptic, meso to microscale, and how the cruising sailor needs to understand and prioritize them.
- A discussion of air masses and how do they relate to synoptic scale WX systems, especially the depiction of associated features on the surface at sea-level WX charts (e.g. the various surface fronts to be discussed subsequently).
- Significant time will be spent discussing synoptic scale WX systems, specifically the dominant middle latitude (30N/S-60N/S) migratory low and high-pressure systems and their associated features from cold, warm, occluded, and stationary fronts, to troughs and ridges, shear lines, and cols.
- The wind and swell waves (sea state conditions) definitions and concepts
- Discussion of the U.S. National Weather Service (NWS) wind and wave analyses and forecast products and how to integrate them with their companion NWS surface pressure analyses and forecasts charts.
- Factoring geographic and local weather effects from surface pressure and wind and wave products.
- A discussion of local marine weather of the Pacific Northwest (Salish Sea), especially noting the gap winds that enhance wind speed conditions between them. There will be an overview of marine weather forecast services from the Vancouver Weather Service Office of Environment Canada and the U.S. NWS Forecast Office (NWSFO) in Seattle.
- Overview of international marine forecast charts, necessary to integrate with cruising to other ocean areas not covered by the NWS.
- Concepts of upper air charts, focusing on 500 Mb.
- Concepts of weather routing as it relates to 500 Mb charts.
- A detailed discussion of the climatology based pilot charts and how to interpret them for potential long range voyage planning.
- Overview of the hierarchy of marine weather analysis, forecasting and vessel routing decision making.
Hands On Exercises:
- From the Bowditch Tables, determine dew point temperature from wet bul temperature exercise and determining relative humidity exercise.
- Determine true wind from geostrophic wind exercise.
- Identifying air masses on synoptic surface pressure charts;
- Determine the correct valid date and time of the principle synoptic scale surface pressure low and high pressure systems and the specific identification of synoptic scale systems’ features exercise.
- Identifying the various symbols on the charts, and the specific weather conditions they will produce.
- Utilizing the Bowditch Wind, Wave, Period and Fetch Tables, determine likely significant wave heights, period, time, and required fetch necessary for these conditions.
- Identifying 500 mb flow patterns.
- How to route a vessel via 500 mb flow patterns.
- Long- range planning route for the North and South Pacific Oceans utilizing pilot charts.
- After reviewing the validity of the most current forecasts, the follow-up to this will be a voyage exercises for the North Pacific Oceans (including portions of the South Pacific) from Anacortes to Cape Flattery to San Francisco to Hawaii onto Fiji and American Samoa.

Women: Build Your Boating Skills
with Capt. Linda Lewis
Saturday, April 8, 2017, from 9 a.m. to 4 p.m. $95
Part 1: Learn How to Navigate – Using the Tablet Program “Navionics” As Your Learning Device
The most popular tablet navigation app among recreational boaters is “Navionics”. Download it to your iPad or Android tablet (or smartphone) and bring it with you. We’ll use it to learn about: chart colors and symbols; putting in a route; monitoring your speed and course; finding tide and current information; pin-pointing your boat’s position; and how to tweak the program’s basic settings. You’ll leave with the ability to practice navigation at home, put in your next trip’s route, and figure the timing of the currents. When you take the tablet on-board, you can use it as a back-up to your boat’s marine navigation system. And you’ll be way ahead of the game because you have already made a plan!
Part 2: The Dance of the Sugar-Plum Currents
Don’t fight the currents; dance with them: underway, at the dock, and at tidal narrows. Should you be in the center of the channel or the edge? Is there a role for the Autopilot when you are underway in ‘currenty’ water? How do you know what the current is doing at the dock? What does the word “slack” really mean? We’ll work problems to make sure you know when places like Deception Pass or Dodd Narrows or Seymour Narrows are safe for transit.
Part 3: The Electronics’ Alphabet: AIS; RADAR; VHF-DSC-MMSI
The Automatic Identification System (AIS) and RAdio Detection And Ranging (RADAR) are both designed to help avoid collisions. Do we need both? What are the caveats in using them? We’ll explore how to use them well. Then there is the little red button on the VHF Marine Radio. Learn how to use the Digital Selective Calling (DSC) button and understand what it does (and does not do).

Hands-on Diesel Engine Training
with Mike Beemer
Saturday, April 8, 2017, from 9 a.m. to 4 p.m. $150
Having your Diesel engine fail while underway can ruin your day. Worse, it could put you and your crew in a dangerous position. In general, marine diesel engines are incredibly reliable. They seem just to need, air, fuel, and water for cooling. You could add electrical power for starting, and you have covered the range of needs for a diesel engine. Most engine problems are due to fuel issues or keeping the engine cool.
Using the Marine Tech Centers diesel engine lab, we will work with live diesel engines running where you can walk around the engine and see the different systems. You can look at the injectors and even learn to bleed the engine before starting.
Here is an example of the areas covered:
Annual and Regular Maintenance:
- Changing the oil and oil filters
- Changing Fuel filters
- Overheating can kill a diesel engine. Make sure your cooling system is maintained including flushing the heat exchanger every 3-4
- There is no warning for salt water incursion in your transmission cooling system. Inspect it annually and replace it every 3-4 years.
- Impellers should be inspected annually and replaced every 1-2 years depending on use.
- Replacing hoses and belts every five years.
- Learn how to troubleshoot electrical systems on your engine for starting or charging.
- Learn how to install a vacuum gauge in your fuel system after the primary fuel filter to tell you if the system has a blockage or if the primary filter is dirty from bad fuel or a problem in the tank.
This is one of our most popular courses, and it frequently fills up in two days. After this one-day course, you will have a good understanding of how your diesel engine works and the basic areas for good maintenance and troubleshooting.
All seminars are held at the NW Center of Excellence for Marine Manufacturing & Technology in Anacortes.
Address: 1606 R Ave. Anacortes, WA 98221
