Woodinville, WA – 20 October 2017—  Field reports about WESMAR’s new powerful Dual Stabilized Beam sonar, the HD860, have been coming in with high enthusiasm from Captains in Dutch Harbor, the Washington, Oregon and California coasts, and as far south as Mexico. With this new sonar technology you can run the transducer in two different modes. A narrow beam searches long range in searchlight fashion, while you can use a wide beam to bottom type the sea floor ahead. It’s a dramatic and very effective development by WESMAR for fishing.

“The HD860 is just one of the money-making pieces of gear for vessel owners that we’ll be demonstrating at our booth,” said Bryan Thiemann of WESMAR. Other significant products fishermen will be able to see at Booth 933 are the company’s trawl sonar and powerful stainless steel counter rotating dual prop bow thrusters.

A local Seattle company, WESMAR brings more than five decades of marine design and manufacturing experience to the Expo. The firm has provided widely respected commercial grade equipment to both private and government operations around the world. Its network of customer support includes over 350 trained service personnel, dealers and distributors. To them, plus the thousands of boat owners and operators around the world, the WESMAR brand means reliable, rugged, commercial grade bow and stern thrusters; high-powered triple axis gyro driven roll fin stabilizer systems, custom hydraulics, and advanced sonar systems.

Seattle Pacific Marine Expo takes place November 16-18 at the CenturyLink Field Event Center, 800 Occidental Ave S. - Seattle, WA 98134. WESMAR is located in Booth 933.


Woodinville, WA —  6 November 2017 —  The M/Y Rumbera, a sports fishing yacht built by Sea Force IX, recently had WESMAR’s new DSP5000 Digital Stabilizers installed.

Owner, Captain Scott Nichols, was so pleased with the smooth ride provided by the WESMAR stabilizers on his previous motor yacht that when he purchased his new sports fishing yacht, Rumbera, he wanted the same system.

What Captain Nichols got however, was WESMAR’s newest DSP5000 Stabilizer, a digital system that has been receiving strong reviews for its quiet, precise stabilization provided in all sea conditions and at all speeds. The Rumbera was fitted with 9.5 square foot fins, each with 932 dual cylinder actuators.

Ramsay Marine Mechanical Services out of Riviera Beach, FL did the installation. The final sea trial was performed out of Ft. Lauderdale, where everything went very smoothly!


“The WESMAR Products are awesome; very good information; impressive clean manufacturing plant; knowledgeable and professional presentations; WESMAR stabilizers are superior to the competition; your products are very well designed and easy to install."   ...Comment from an attendee of the 2017 Dealer Training seminar

Woodinville, WA – 16 August 2017 –WESMAR congratulates the technicians and sales personnel who attended its annual Mechanical Training Seminar August 14 and 15 at corporate headquarters in Woodinville, Washington.

“This popular annual seminar offers classroom and hands-on training on the company’s complete line of marine equipment and is widely attended by the dealers. We include both classroom and hands-on instruction on installation, service and maintenance of WESMAR’s triple axis digital stabilizer systems, rugged all stainless steel bow and stern thrusters and custom hydraulics,” said Vice President Bob Sentz.

WESMAR is widely recognized as the leading US Company in advanced marine sonar systems, hydraulic and electric counter-rotating dual prop bow and stern thrusters, and roll fin stabilizer systems for yachts and commercial vessels.

Founded in 1965, WESMAR designs and manufactures at its 82,000 square foot facility near Seattle. From there they ship product around the world.

Woodinville, WA - 10 August 2017 - Jerry and Jenni Nelson, owners of the beautiful custom 43-foot 2009 Selene, ‘FOREVER YOUNG’ are ardent boaters and sport fishers, and fans of WESMAR. They have three WESMAR systems on board their boat, including an APU (Auxiliary Power Unit) get-home system, roll fin stabilizers, and bow and stern thrusters. Captain Nelson gives powerful reports about all of them.

“We keep our stabilizers on all the time, and we call them marriage savers!” said Captain Nelson.

"We ordered WESMAR stabilizers after the Selene Rendezvous in 2008 before we had even taken delivery of our new boat.  That year there was harsh weather the day of arrival and as boats arrived we soon observed there were two camps of boaters…those with stabilizers and those without. Those with were apt to say ‘it was rough weather;' those without said ‘OMG that was rough!’ ”

“Jenni, who does not enjoy rough-weather cruising, said we really need to add them, and she sure appreciates having them. The first thing we do when cruising is turn on our stabilizers even if the weather is not rough. We like them on all the time because then there are no surprises from beam seas or from the wake of ferries or other large boats."

The WESMAR AUXILIARY POWER UNIT (APU) Saves Us from Severe Damage ...

“Last year when we were leaving our anchorage, my fuel pump went out, and it kept us off the rocks. It was a touchy situation. Heavy currents were carrying us rapidly toward the rocks; Jenni even had our push pole out hoping to ward off disaster, but we knew it was no protection against the 72,000 pound boat fighting her. We were within 20 feet of crashing into the rocks when I turned on the APU and the boat started moving away from the shore -- it saved us.”

“I actually use my WESMAR APU mostly for trolling. It is how I control my boat during fishing and I use it all the time. This past year we spent 5 months in SE Alaska and British Columbia, Canada, fishing for halibut and salmon. It was a good year. In Alaska, we caught 500 pounds of halibut, including a 205-pound halibut. Most of our salmon was caught on our way home in northern B.C.”

 “Once we get out to the area we plan to fish, I shut down the Main engine, start up my generator, and using the APU I adjust the proportional speed joy stick to keep me at 1.5 to 2 knots, but we found it will operate at 4.5 knots if needed.It replaces the use of a trolling valve, which most boaters install to achieve the lower speeds required for trolling. We upgraded our generator to a 12 kw one to accommodate the power required to operate the APU’s Hydraulics." 

We use the WESMAR bow and stern thrusters for docking and maneuvering! They make everything so much easier.


Woodinville, WA – 16 August 2017 - A deck load of shrimp is not something you are generally prepared for. Usually a net full is a wonderful bounty. Just ask Buddy King, Captain of the 78-foot FV Pacific Hooker out of Brookings, Oregon,  who has been using WESMAR’s new dual stabilized beam HD860-60kHz sonar in the Shrimp Fishery off the California, Oregon, and Washington Coasts. He recently pulled in both his trawl nets one after another, filling up not just his fish hold but his deck as well with shrimp.  

His assessment: “WESMAR’s stabilized dual beam sonar helps keep me out of trouble. It protects my nets when going over rocks. I can locate the hard bottom where I risk ruining my nets.”

“The WESMAR sonar gives good distinction between hard and soft bottom.  Without it you can’t see. I fish the coasts of Washington, Oregon and California. I just can’t remember the whole coast, so this sonar is a great help.  I use the narrow beam to look far ahead and the wide beam for a more detailed picture of the bottom.

“Last year, without this sonar, I tore 3.5 nets; and this year just one and that was my fault. It was my first shrimp trip with the WESMAR and I didn’t believe what the sonar was showing.” “Tearing nets is expensive. Not only to replace, but we lose costly time.  I carry two spares with me to avoid the down time. And even with spares on board we burn up costly time switching them out. It easily burns up half a day,” said Captain King.

“Reefs can be a big problem when fishing crab and the WESMAR is good for locating those too.”

The Pacific Hooker is part of the west coast shrimp trawler fleet. Captain King and his crew filled his boat with a big deck load of pink shrimp 18.5 miles off the coast of Washington. “We used the WESMAR to follow the edge between hard and soft bottom. This way we protect our nets and still harvest the fish. These fish were at 80 fathoms.

"I use both of the beams, the narrow one for long range and the expanded one to map the bottom in more detail.  Before the WESMAR, the risk of tearing up the net kept me from navigating near a lot of places."

Woodinville, WA – April 25, 2017 – Only about 10% of the Northwest Passage has been properly charted, according to the US and Canadian Coast Guards.  So Crystal Cruises installed WESMAR’s navigation and security sonar for underwater surveillance before its 820-foot long luxury cruise ship CRYSTAL SERENITY embarked on its historic 32-day trip through the Passage last summer.  

One thousand passengers made the voyage via the Canadian Arctic and Greenland having paid upwards of $22,000 each. The cruise took passengers through areas of exceptional wildlife sightings, stunning displays of nature, and rare experiences. The cruise was so popular and the ship so elegant, the company has announced they will repeat it again this year traveling the same 32-day schedule leaving from Seward, Alaska, August 15 and arriving New York Harbor, September 16, 2017.

“The WESMAR EV850-110kHz-10 inch Navigation and security sonar is operating on many other cruise ships around the world where operators are unwilling to travel blind to the waters ahead and around the vessel.  It is used for detection of icebergs, underwater rocks/pinnacles, and reefs and for scanning harbor entrances for safe passage and anchorages for mooring hazards. The system provides 360 degree monitoring of the water around and under the vessel to protect against groundings and even hostile underwater intruders,” says WESMAR.

WESMAR, located near Seattle, WA, has been an industry leader in the design and manufacture of sonar for over 50 years, providing specialized equipment for government, commercial and private. WESMAR sonar is used for navigation, security and fish finding and is operating on vessels operated by navies, municipalities, cruise ships and a wide range of fishing operations around the world. 


Woodinville, WA – 21 June 2016 -- WESMAR has announced the introduction of the DSP5000 Wave-Smart® Stabilizers, a dramatic new line of roll fin stabilizer systems they say will change the way you measure comfort. Among other advances, it introduces WESMAR’s proprietary Continuous Feedback Adaptive Controller (CFAC)* technology.
“This system is a stunning success,” reports WESMAR.  “After months of field testing, here is what captains of some of the world’s most elegant yachts have reported:

‘It’s very smooth. No roll at all.”
“I highly recommend this upgrade to any vessel.”
Once the calculations using your normal cruising speed are set, it is totally automatic. You set it and forget it!
“In our testing it provided smooth, seamless fin movement at Anchor or underway.”
“In my experience, WESMAR makes outstanding products and supports them well. This new controller is no exception.”

The new DSP5000 series is available on all new systems plus as an upgrade to existing WESMAR Stabilizer systems and many competitor units.

WESMAR says the Wave-Smart’s predictive technology using actual vessel motion to determine exact response will change boating comfort forever. Among its many features for vessel stabilization is session capture, which is the ability to record to USB, and NMEA 2000 plug in, the ability to run the fins at different speeds and much more.  It offers faster response, smoother stops, ease of installation, and replaces chasing and wasted energy and noise.

*About Continuous Feedback Adaptive Control

(CFAC) when applied properly is of great value in taming hard-to-tune process loops. It will also tune a typical process loop more precisely.

Adaptive tuning, adapts to the dynamics of the process and will tune “on the fly,” responding to certain process criteria as determined by the specifics of the adaptive algorithm being used. It changes the PID (Proportional Integral Derivative) values to respond to the change in the process. When applied properly, it is of great value in taming hard-to-tune process loops. It will also tune a typical process loop more precisely.

Woodinville, WA - 10 May 2016 --The list of passenger and car ferries around the world got even longer this month when WESMAR received orders for two more ferries. The WESMAR design delivers the extra power needed for high-speed ferries and the two new vessels will operate at a service speed of 27 knots. They are under construction at Kvichak Marine Industries for the Water Emergency Transportation Authority (WETA), San Francisco. Kvichak (a Vigor Company) won the $32 million contract for the 135-foot, 400 passenger-only, all aluminum catamaran ferries providing each with  two WESMAR hydraulic V2-12 dual prop, counter rotating bow thrusters, one in each hull. WESMAR’s unique counter rotating design provides up to 40% more thrust without increasing the tunnel size so they are perfect for the job. Each system will include three control stations in the pilot house.
In addition to its reputation for high quality, WESMAR’s rugged all stainless steel bow thrusters are US built with US parts meeting another stipulation in the  contract. WESMAR is one of the remaining few thrusters designed and built in the USA. The new vessels are expected to be in service the summer of 2017.
