![]() ![]() Often, we will come up with the look of the vessel and hand that off to them to basically translate into a buildable project. Then, not only is the design side of what they do very good, the actual engineering of it is very good. “Their team is very flexible in accommodating customers’ needs. “Elliot Bay has been a very key partner for us because they share our vision that having quality renderings available for people to review is such an important thing, more than just blueprints,” Gracey said. The vessel can be operated with a one-person crew and does not require compliance with USCG Subchapter M regulations. Available with either electric, hybrid or outboard propulsion options with up to 500 horsepower, the tug will produce a bollard pull over 12,500 pounds and has a still water range of 60 nautical miles pushing approximately 10,000 pounds at 4.1 knots. ![]() Silverback has worked with EBDG on a number of other projects, including a truckable tug, a compact (25’ 10 ⅞” length, 14’ 6” beam 3’ 4” draft) tugboat that can be transported to job sites by truck over the road. Once that was approved, we contracted Elliot Bay Design Group to flush out the whole gamut,” Gracey said. From there, we drafted up a rough concept. “Essentially, Shaver gave us a list of the things that they wanted to be able to do, and some rough ideas of the weight, and size, and length that they were aiming to keep within. The initial design for the vessel was based on Silverback’s standard Grizzly, which is a 21-footer. Among other innovations, the flat deck sheds all water overboard, thus eliminating the need for auto bailers. It will feature windows and a wheelhouse door from Diamond Sea Glaze and will be powered by twin 300-horsepower OXE Diesel outboards. The wheelhouse will seat up to six people, including pilot and co-pilot plus four crew. The vessel will have full fendering, enabling it to sidle up to a larger ship, and push knees for utility work moving floats or any kind of maintenance around the harbor. For example, if they need groceries delivered to a bigger ship, or simply need to get a number of personnel from one vessel to another quickly, then this boat will allow them to do that,” Gracey said. This vessel is designed to bring crew and items from various places onshore out to larger vessels. “It’s not a crew transfer vessel in the sense of offshore wind. Scheduled for delivery in 2023, the 35’ 5” vessel will be operated by Portland, Ore.-based Shaver Transportation on the Columbia River. ![]() In July 2022, Silverback began building what it calls a STS CTV, a crew transfer vessel for ship-to-shore applications. ![]() The company is now in its third year of business, and to date, it has built 51 vessels with four builds currently underway. Silverback’s customers range from ports and municipalities to oil response and tug and barge companies, “anyone who’s in the market for a workboat between 21 and 60 feet,” Gracey said. If a customer needs a boat quickly, they can have it in as little as one to two days.” “For our Grizzly, which is kind of like the F-150 of workboats, we premanufacture in production runs of 10 at a time and have them sitting either fully or partially complete. “The way the industry is now, the lead time can be anywhere from six to 24 months if you want to get even a basic workboat because most people build to order,” Gracey said. builders aiming to accelerate delivery times by keeping an inventory of stock vessels-which is especially beneficial given the current supply chain issues that are plaguing newbuild projects. Silverback Marine is among a number of U.S. Enabling people to get a smaller workboat, but also have a real naval architect and engineer go through it-give them renderings, give them that tailored experience that you would normally only find if you’re getting a much larger vessel,” the company’s founder, Ian Gracey, said. “We started Silverback with the vision of essentially bringing, what I would call, the big boat experience to smaller workboats. Tacoma, Wash.-based Silverback Marine is a relatively new name in boatbuilding, formed with the tall ambition to “change the way the world thinks about workboats”. ![]()
