I'm not really sure how this happened, but I set out to write a blog about the possible reemergence of sail power, and ended up thinking about the extinction of our species. Thank goodness February is almost over.
I will try to explain. Today I read about a commercial fishing and gear firm from the Shetlands that was awarded a research grant for almost $11,000. The money will help the company move toward its goal of developing a sailing mast system for commercial fishing boats.
Sail Line Fish unveiled the Balpha Mast prototype in 2011. The project began five years ago when gas prices spiked. The collapsible mast is designed to be put in use when conditions are favorable for sailing and without needing extra crew.
There's no overstating the importance of fuel prices on commercial fishing. I've seen fishermen do the gas math, trying to decide whether it's worth the extra cost of steaming farther out. Even if the catch is more abundant, it may be offset by the gas it took to get there.
The Balpha Mast seems to have potential. In a 2011 feasibility study, 17 fishing trips were made covering 136 nautical miles. Of that distance, 33 percent was under sail, reducing fuel consumption by 17.6 percent (taking into account all fuel use, including setting and hauling lines).
The company, which has been funding the research with sales of its own line-caught fish, next plans to design and build a sail-assisted fishing vessel to test and trial the system. Stuart Balfour of Sail Line Fish says it has had interest from fishermen both nearer to home and all around the world, including Malaysia, Dubai, Maldives and Nova Scotia.
We've gone from sails to steam to internal combustion to diesel and now possibly back to sail again. Seeing this shift in technology is fascinating to me. I wouldn't say this is a step backward but that our definition of moving forward has changed. That's pretty monumental when you think about it.
When I'm in a certain mood, I like to read about the collapse of societies and our own inevitable end. Which is why I started thinking about the Fermi paradox. It's the idea that the universe is so vast that intelligent life MUST exist on other planets.
The paradox is why haven't they visited us yet? One theory is advanced societies tend to move in the direction of self destruction — we have the capability of destroying ourselves before we're smart enough to use it wisely.
That's all conjecture, but it's so interesting to think about. At least for now, new technology is reducing our impact on the planet. More importantly, it saves on gas. Check out a video of the Balpha Mast in action below:
NMFS recently released a draft action plan for fish discard and release mortality science, creating a list of actions that they hope can better inform fisheries.
We know that fishermen have to deal with bycatch by discarding or releasing unwanted catch overboard, but there is a data gap regarding how those fish survive.Read more...
A new study has identified a set of features common to all ocean ecosystems that provide a visual diagnosis of the health of the underwater environment coastal communities rely on.
Together, the features detail cumulative effects of threats -- such as overfishing, pollution, and invasive species, allowing responders to act faster to increase ocean resiliency and sustainability.Read more...
