Davis Whale Tail XL
The Davis Whale Tail XL stabilizer and ski boat fin improves performance in any I/O or outboard motor.
- Increases top speed and fuel savings in most applications
- Marine grade aluminum with durable anodized finish
- Reduces porpoising & cavitating

The Whale Tail XL extends out behind the prop to utilize prop wash energy which is normally lost. Whale Tail transforms this energy into lift for immediate response when the throttle is applied.
- Unique hydrodynamic design
- Stabilizes bow-light boats
- Pops skiers up in less time
Flattens wake for water skiing; creates positive, skid-free turns:
- With bow lowered, visibility and safety is improved
- Smooths out ride in rough water
- Mounts on the anti-cavitation plate of all inboard/outboards and outboards
- Installs in 15 minutes with stainless steel hardware included
- Use the Whale Tail XL year-round in freshwater or saltwater to improve performance of any boat!

Since 2003 harmful bacteria Escherichia coli (E. coli) levels have created a health risk to recreational users in Boulder Creek. Boulder Creek has been designated as an impaired stream and is not meeting an EPA health-based water quality standard.
Concentrations of E. coli increase from the mouth of Boulder Canyon to the University of Colorado-Boulder and beyond based upon data collected by the City of Boulder according to information published by the CU Independent and the Boulder Camera . EM spoke to environmental engineer Art Hirsch of the Boulder Waterkeeper , who is advocating for greater accountability from all entities that own property abutting the stream.
The National Oceanic and Atmospheric Administration (NOAA) and the Pacific Islands Ocean Observing System (PacIOOS) at the University of Hawaiʻi at Māno a , in collaboration with other partners, recently deployed a new ocean acidification (OA) monitoring site in Fagatele Bay National Marine Sanctuary , American Samoa. Derek Manzello , a coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) in Florida, is the lead PI of ACCRETE: the Acidification, Climate and Coral Reef Ecosystems Team at AOML. Dr. Manzello connected with EM about the deployment.
“ACCRETE encompasses multiple projects that all aim to better understand the response of coral reef ecosystems to climate change and/or ocean acidification,” explains Dr.Read More
Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work.
“Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.”
Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean.
“The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.Read More
