About The Baylis

The Derek M. Baylis (DMB) is a 65-foot auxiliary-powered sailing research vessel that was specifically designed and constructed to provide a safe, comfortable, fast, and environment-friendly platform for marine research and education.

She has many modern features that uniquely qualify her as a 21st century sailing research vessel.
There are sleeping quarters for 12 passengers and 2 crew in three staterooms and two common areas with a mini galley, chart station and comfortable seating around a table in the pilot house.

The “Baylis” also sports a customizable deck, strong but ultralight construction, a "slippery" hull design, and the minimalist rigging consists of freestanding, tapered, carbon fiber masts - whose flexibility eliminates the need to furl the sails in high wind. When a gust comes up, the boat doesn't lean over—it accelerates. The simplified rigging makes her easy to sail, and allows the boat to run charters of up to 42 people with only a skipper and a single crew member aboard.

The boat's rear transom is wide and detachable, and its deck is riddled with bolt holes, enabling crew members to easily secure and deploy a wide range of equipment—something that can't be done on most sailboats.

The use of the Baylis generally improved data quality through the reduction of self-noise, and for a fixed budget it allowed us to triple the length of the cruise. At that point I was sold on using wind power on research vessels as a solution to budget and data quality problems. If the opportunity arises again, we’ll be using the Baylis for future work.

The Derek M. Baylis provided us with a quiet and relatively stable platform while under sail, which increases our chances at successful acoustic detection of relatively quiet beaked whales. Our fuel use was just a trickle of what would typically be required for this type of work and our carbon footprint was more of a toe print. We recommend this vessel for projects of this nature, and hope to use it again in the future.
