Love Him or Not Book Review


 
Book CoverCapt. Larry Simns has probably had some effect on your life if you are in any part of the seafood industry, if you like to fish, if you are concerned with water quality, if you love to eat seafood, if you live or work near the Chesapeake Bay and its watershed, are a politician in the Maryland State House, or for a variety of other reasons. If you dont know his name, or the only thing that you do know about him is his name, then you should read this book.

In the newly released The Best of Times on The Chesapeake Bay, An Account of a Rock Hall Waterman, Capt. Larry Simns (the n is silent), and co-author Robert L. Rich, Jr. tell the story of how he grew up in the small harbor town of Rock Hall on Marylands Eastern Shore. He began his education in seafood harvesting at six years old, he went through brutal but valuable apprenticeship with seasoned and unforgiving Captains in his teens and he grew to become a respected Captain and seafood business owner in young adulthood. He recounts how he reluctantly found his voice as he began his rise within local groups of watermen to become a legendary advocate for them and the Chesapeake Bay in response to critical declines in seafood populations in the early 1970s. In his 40 years as President of the Maryland Watermens Association, he was not only recognized for his work by professionals with interests in the fisheries from Maine to Alaska and the Gulf Coast, he also worked with Senators, Governors and U.S. Presidents.

If you spend any time with a waterman,it would be difficult not to notice that theirs are very tough jobs. Many of our neighbors start their day at 3:00am. They work when its 20 degrees outside. They work when its 100 degrees outside. The brutal apprenticeship that Capt. Larry went through was important for learning to live in an environment that might be idyllic one moment and potentially deadly the next. There are some very exciting moments in the book. In fact, Capt. Larry went through more than one situation where he almost didnt survive.
 
He clearly explains how various finfish, oysters and crabs were harvested, having experience with pretty much every method used. He explains how "The Bay" changed after Hurricane Agnes. A resulting drop in seafood harvests coincided. Other factors including pollution from other sources led him to the chain of events that made him the powerful advocate he is. He discusses how he worked with others from various disciplines including biologists, environmentalists, and others to create policies that were not always popular. An amazing journey for a waterman from Rock Hall, Maryland.
 
Theres a whole lot more here and I highly recommend this book. Most of the chapters are brief, but full of information. It provides an education about the Chesapeake Bay, Eastern Shore life, the history of its watermen, issues surrounding its protection and much more. One gets the sense that, knowing he wont be around forever, he would like for this book to help pass critical information to those for whom stewardship of the Chesapeake and the life within it will pass. We should pay attention.

To Paint or Not to Paint

Last week the builder of one of my boats asked me about painting the interior of his boat, what should he paint and what shouldnt he paint? I had not really thought of it before, that there are different thoughts about what to paint and why. Before I answer, I will tell you of my experiences on a wide range of boats, those built by me and those built by others.

On all of the big boats that I have built (they were all for my own use), people who visited the boats or sailed with us often commented about how fresh they were down below compared with their own boats or others on which they had sailed. I had observed this as well. There was never any diesel smell, never any dank, damp odour and never any need for air fresheners on my own boats. In contrast, many of the other boats were oppressive as soon as I went below, with some rather bad smells.

Most of these boats had been owner-built or owner-completed and they all had large areas of plywood that were unpainted, left as raw timber, under berths, in the bilges etc. My own boats had no exposed timber, not inside lockers, under cabin soles, inside the lazarette, under berths, not anywhere.

So, how does this make such a difference? A boat lives in a wet environment and most are closed up the majority of the time. When the sun is shining, the inside of a boat is much warmer than outside and that warm air soaks up moisture from any water that is in the bilge or elsewhere. Humidity builds up and creates an ideal atmosphere for mould to grow. Mould spores are in the air all around us and waiting to proliferate.

When the air cools in the evening the moisture is wrung out of the air again. It settles as condensation on hull, deck and joinery surfaces throughout the boat. It doesnt care whether they are exposed surfaces that you see whenever you are on the boat or hidden ones that you seldom see. The humidity is everywhere in the boat when it is hot, so condensation settles everywhere when it cools.

The unpainted wood surfaces absorb some of this moisture and hold onto it. It becomes that ideal environment for the mould spores to settle and grow. Once it starts, if left unchecked, the mould will spread throughout the boat and can also be the start of rot problems.

Mould inside the boat can be difficult to kill off. It needs to be killed everywhere and the surfaces must be thoroughly dried then sealed with epoxy or paint so that the cycle doesnt start again. It would have been so much easier to have just painted everywhere when the boat was being built. Sure, painting everything will have added a few weeks to the build time but it will have been worth the extra effort to save the hassles of the future.

The same principle applies to preventing diesel smells. Every big boat has a diesel or oil spill or two in its life.That liquid will soak into any raw timber that it contacts. Once into the surface it is impossible to remove and it will result in diesel or oil smells inside the boat for the rest of its life. If those surfaces had been painted then the problem would never have arisen.

So, what coatings should you use? All surfaces of the hull and deck skins, as well as all associated timber framing (stringers, backbone, beams, sheer clamps etc) must be protected by three coats of epoxy. This should include the perimeter of bulkheads against hull and deck but you may prefer to coat all bulkhead surfaces as well. The epoxy needs to be protected from the attack of UV (even below decks) so I recommend painting over the epoxy with a prime coat, followed by undercoat and finishing coat of paint.

Elsewhere, coat with primer, undercoat and finish coat. That means every timber surface, whether you will see it again or not. If it is a sealed compartment, e.g. inside a swim platform, dont leave it unpainted either. These sealed compartments must be coated inside with three coats of epoxy but you dont need to paint them.

Aside from mould, smell and rot prevention, there are other reasons to paint everywhere. 
  • Painted surfaces are very easy to clean. You can throw a bucket of water in the bilge or a locker, swill it around and then pump it out, no harm done. Or you can wipe it down with a damp cloth or sponge rinsed in a bucket, very easy.
  • Light-coloured paint reflects light, unlike raw timber that absorbs it. The painted compartments are bright and make it easier to find things that have gone astray. A fully painted lazarette is not a dungeon that swallows up tools and other things that will not be seen again until you build up the courage to dive into that dark place in search of lost treasures. That also applies to cabins in the ends of the boat, which are much more bright and habitable if painted in light colours. Clear-finished okoume plywood becomes quite dark, has uninteresting grain patterns and is not as attractive as you might imagine, not by a long way.
This problem is not limited to owner-built plywood boats either. I have seen this regularly when poking around inside boats displayed on boat shows in London, Annapolis and other places. Many production builders dont bother to protect the timber surfaces inside lockers, lazarettes, berths or the bilge. It costs them labour and materials to do so and it costs the owner down the line to sort it out or live with the results.

So, dont bother to argue with yourself over which surfaces to paint and which to leave raw, just get down to it and paint them all. You can thank yourself later when you reap the benefits.

Allied to this is the need for good ventilation. Strategically positioned ventilators will help to keep the air fresh inside your boat, removing excess moisture and making it a much more pleasant environment for people instead of mould.

Not Another Storm Surge


In the last few days weve again experienced "storm surge", which is something that caused a great deal of havoc here along the Chesapeake Bay during hurricane Isabel, back in 2003. That seems minimal compared to what has occured in the past few days from New Jersey to New York City and beyond because of Hurricane Sandy.


Storm surge has to do with water rising in response to winds from a storm. Storm surge along ocean beaches is usually larger and more intense than in bays and tributaries, where the intensity is controlled by a number of factors. Not being a Meteorologist, mine will be a loose explanation.

How storm surge occurs in a body of water such as the Chesapeake Bay has to do, not only with a storms strength, but where the storms center is relative to that Bay. The main winds of cyclones in the Northern Hemisphere spin in a counter-clockwise direction, thus a storm traveling on a Northwest track and coming ashore South of the Bay will create winds that move from the Southeast to the Northwest, which is to say up and into the Bay. Isabel traveled just such a path and piled great amounts of water into the Bay, resulting in a large Storm Surge. Many people were severly hit by flooding; some losing their homes to that storm surge, both along the Bay and throughout its major rivers and tributaries.

Our shop, which is along the water, was badly flooded in Isabel and ever since we have been wary of any major storm that comes up the Atlantic to our area.

Our workshop after Hurricane Isabel in 2003 (in the early
days of digital cameras).
Sandy,unlike Isabel, traveled a Northwest path, but came ashore North of the Bay and the counterclockwise push of water was largely out of the Bay. That is, during the initial impact. As Sandy moved inland part of that circular motion began to push from the Southwest, but with far less impact than Isabel. You may want to play with a compass and piece of paper to illustrate the principle.

Hurricane Sandys path was North of the Chesapeake Bay.

Twice, the storm surge from Sandy moved to within a few feet of our shop, causing a lot of stress, but neither time did it quite get inside. We were extremely lucky. From the information I could find I believe that our storm surge was probably about 3 feet above mean high tide. Here are two, very different photos of David and the Annie Buck, one from the first day that the rain bands came ashore, the second taken during the storm, but a short time before the peak of the surge. Notice the differences in, not only the height of the water, relative to the pier, but also how much higher the boats are floating.

An average high tide here is not much higher than this.

This is a dangerous situation. The storm surge has reached a little under 3 feet.
If you could see the shorelines, the creek looks much larger than normal.
We were lucky around here. A lot of other people faired far worse and our thoughts are with them. I know that there was a whole lot of damage North of us. Depending upon how bad that damage is, this storm may be remembered for taking the tall ship "Bounty". Like most hurricanes, there are a lot of stories that will come out of it.
