Projects Aboard Evelyn

April 30, 2015

(port side) compared to last spring (starboard side)
It has been one year since we completed our sail along the East Coast and returned, after seven months of travel, to Mount Desert Island, Maine on April 30, 2014.  The day after our return we set to work for a busy spring filled with outfitting boats and then a summer spent sailing Friendship Sloops for charter.  As the summer drew to a close we embarked on a new adventure, and spent the fall and spring aboard a private ketch, once again cruising along the East Coast and also sailing out to the Bahamas.  Evelyn, meanwhile, was hauled out in September and winterized for the first time in our ownership—previously we’d always stayed aboard year-round.  But the timing for this first extended haul-out was perfect—by the end of our cruise last year we had identified some large projects aboard Evelyn that would require a longer work period and dry working space, so we found storage indoors and prepped to begin projects in the spring.

Our busy year has kept me far, far behind in my posts, and I do plan to eventually share the rest of our travels last year as well as our experiences this year, but in honor of the one-year anniversary of our return, I thought it appropriate to share a more current update on Evelyn.

As most of those living along the East Coast know from personal experience, this past winter was a record-breaker, with plenty of snow, ice, and brutally cold days.  For most of the winter Lou and I were lucky to be sailing down south away from the blustery weather, and we were very grateful that Evelyn was safely winterized where we would not worry—just before we left Maine in the fall, we found storage for Evelyn in a boat shed.  Although the cold still reached her, she escaped the wind, snow, and rain that defined the winter and when we were reunited with her last week,  we were excited to find her just as we left her.

Lou peeled the fiberglass away from
the bulwarks last fall so that the
wood had the opportunity to air out
over the winter months.
We began our projects immediately, because we recognize that they are ambitious and time-consuming, and despite that, we hope that we will still be able to launch, live aboard, and sail Evelyn this summer.  But these projects cannot be put off, and must be done properly and completely, because these projects involve rot, so we will see how much we can accomplish before summer.  We have suspected for a while that there was likely rot in our bulwarks, potentially rot in our upper planks, possibly rot in our deck edges, definitely rot in our guardrail, and maybe, though hopefully not, rot in the upper edges of the frames.  Since beginning our spring outfitting a week ago, we have found rot in all of those places.  As soon as this became apparent we committed ourselves to a few things: 
  1. To remove the rot in these places entirely, instead of hoping to fix the problem piecemeal over a number of years, to inhibit the rot from spreading any further.  
  2. To replace and repair in a manner that does not mimic any conditions that may have caused the rot, in an effort to preserve our repairs longer.  
  3. To dive right in, right now…because although it may at times seem overwhelming, sometimes the most difficult part of completing a project is committing to the process and getting started.  We did not want to waste the time we have gingerly removing small areas of rot, only to find that our suspicions were correct and large areas were unsalvageable anyway.


With these notions as our guidelines, we found ourselves borrowing a saws-all and cutting away Evelyn’s bulwarks within hours of our arrival in Maine.  We were anxious at first but soon glad we did so—though all of the elements of the boat were still strong as a combined unit, individually they were poisoned with rot.  As we suspected the bulwarks were in fact unsalvageable, and hiding graver problems beneath them.  They had lasted for thirty years, but it was time to go—we were glad that we dug right in and removed them entirely, because we feel that if we had not addressed the problem now, it would soon have begun to spiral out of control.  We hate the thought of Evelyn rotting around us—during our ownership, we hope to be caretakers that make her better than we found her, in every way possible.

Some hard-to-reach areas where
the bulwarks, deck, and guardrail
met simply fell away, leaving old
screws standing in place.
As they were, Evelyn’s bulwarks were constructed of strip planks built atop a deck of double-layered half-inch marine plywood.  The top layer of the deck sat atop the upper planks of the hull, the bottom layer of deck sat just inside; the hull is strip planked in construction, cedar over oak frames.  Outside the upper hull planks was a guardrail.  Over the deck was a layer of fiberglass, which then bent up the inside of the bulwarks.  Over the bulwarks was a strong mahogany cap rail, and then the outer layer of strip-planked bulwarks was finished with a layer of fiberglass that then went over the guardrail.  Water always finds a way, and so water found its way into those edges where the fiberglass ended, into the bulwarks, and then, sandwiched by fiberglass, stayed there rotting the wood of the bulwarks, before continuing on to the outer edges of the top layer of deck, sometimes the outer edges of the second, often the upper planks of the hull, and sometimes the tops of the frames.  At some point in Evelyn’s history the problem was apparently recognized and some repairs were made—based on the different woods, glues, screws and nails and a bit of sleuthing, it seems that the frames originally supported the bulwarks, but were later cut down below the decks, and then bronze supports were made to support the cap rail.  Some deck was replaced at some point, but not brought out to edge of the boat or below the bulwarks—there the old plywood was left, and it continued to rot and that rot spread to the planks and frames. 

After ten days of work, we are still in the demolition stage, but have so far managed to:
  • Remove the mahogany cap rail, which was mostly in fine condition and which we hope to salvage.
  • Remove the rotted guardrail (or rubrail, as it is also known).
  • Remove all of the hardware on the bulwarks and deck, for re-installation later.
  • Remove the bulwarks.
  • Remove the top layer of deck, until good healthy wood was found.
  • Remove the bottom layer of plywood deck where rot was present.
  • Remove the construction at the bow and stern to check the stems for any rot or damage.
  • Remove a small rotted beam in the stern, as well as sections of rotted sheer clamp. 
  • Remove the decorative teak decking in the cockpit so that it can be re-installed later, to address areas in the cockpit where bad rot was found.
  • Line off the hull for a new sheerstrake.


What we plan to do next:

After fixing areas that had experienced damage from rot in the bow and stern, by splicing in new wood and sistering as necessary the frames, sheer clamp, and deck beams, we will then make templates so that we can replace the damaged areas of the lower and upper layers of deck with new marine plywood. 

Meanwhile, we have decided that because the thin strip planks curve upward and the rot is in many ends instead of one plank, we will replace the upper planks with a new sheerstrake, instead of many little spliced-in areas.  It is Lou’s dream to in the future convert Evelyn to carvel planking as we find the need to replace the old strip planks, so this will set us up for that move when the days of re-planking arrive.  He personally finds the carvel planks easier to replace than the strip planks, so has

been thinking of this for some time, and the Tahiti was originally designed for carvel, so all the frames and structural elements are appropriate for a conversion.  This change will also keep the planks’ end grains from being exposed at the deck, where capillary action through the wood surely contributed to its demise—on Evelyn, the narrow strip planks were laid atop each other from the bottom up without any stealers, so when one looks at the side of the boat she appears to be smiling, with the ends of the planks pointing upwards.  We hope it is the right decision for Evelyn, but are certain it is the right decision for us being able to more easily maintain her hull in the manner that Lou is most comfortable with.  So after Lou spent some time conferring with some boatbuilding friends and referencing his favorite books, we then wandered around the boatyard with a measuring tape and a notepad, closely inspecting all of our favorite boats, observing the shapes and tapers of their planks, and attempting to learn the art of a beautifully shaped plank.  I then spent the day measuring and drawing onto the hull where we’d like our new sheerstrake to join our lower planks, and we then stretched battens of wood along that sketched line—to see it more clearly, to smooth it out, and to provide a guide when Lou cuts away the existing strip planks.

We’ve already prepared the materials we’ll use to make templates for the new plank and areas of deck, which will be the step before creating those new pieces and installing them.  After a new plank and new decking is in place, we will then redo the layer of fiberglass to match the areas of deck we’ve left untouched.  But instead of once again bending the fiberglass up the bulwarks, and then bringing it down the outer side of the bulwarks and over the guardrail, we will instead bend it only over the edge of the deck, and then pin it down with the new guardrail.  Our hope is that though water is sure to still find a way somehow, we will at least have made it more difficult because the edge of the fiberglass will no longer be exposed and therefore (hopefully) less likely to delaminate.

The bulwarks, when re-instated, will also be installed differently.  We intend to make Evelyn’s new bulwarks open, so that water can drain more quickly.  The worst areas of rot were often at the

rot, nearby a former scupper
scuppers, so an open bulwarks should help decrease that.  This will also enable us to quickly tack up a temporary bulwarks for this season, so that we can refine our plans for a new bulwarks and work on them next spring.  The new bulwarks will connect to the deck with bronze braces—we’ll be able to reuse about a dozen we already have, and have just a few more fabricated.  And with the new bulwarks separated from the deck, we’ll be able to separate these two rot-prone areas so that maintenance work can be more easily done in the future.  We’ll also eliminate the need for the fiberglass on the deck to go over the bulwarks, so that they can be—like the rest of Evelyn—simply made out of wood.  And if one day in the future we have to replace more decking, or choose to improve upon it, we won’t have to destroy the bulwarks again to do so.

But after the deck is finished, a temporary bulwarks will do for this year, so that we can continue to focus our energy on completing the bulk of the project now underway.  In addition to replacing the sheerstrake and decking, we’ll also need to rebuild areas of the cockpit, bow, and stern that were dismantled to make sure that we didn’t accidentally miss any rot.  Select deck hardware will be replaced, though we hope to eliminate anything we no longer need so that there are not more holes than necessary in the newly replaced areas of the deck.  For example, an old deck fitting to pump out the holding tank was a weak area in the deck surrounded with bad rot—with the composting head we installed years ago, there is no reason to replace this fitting.

We hope that we’ll be able to complete all of that, in addition to Evelyn’s regular maintenance schedule—new paint for the deck, hull, and bottom; new coats of varnish for the spars, hatches, and cabin; and all the many other little things a boat needs each spring.  We hope to finish it all in the next month, but if we can’t, we can’t.  We’ve already accepted the fact that there is a possibility that this summer we may be without our dear Evelyn, but it is an acceptable outcome if that’s what it takes to get the work done as best we can.  If we want to enjoy her, we must take care of her, and every now and then these bigger projects will arise.  After all, it was thirty years ago that Evelyn’s builder Ben Severns was just putting the finishing touches on his eleven-year project, preparing to launch Benelly, as she was then known, into the Great Lakes so that she could make her way to the ocean and begin her journey.  In honor of her thirtieth birthday, the least she deserves is a little pampering!

Here are links to a few posts from when we replaced large areas of the deck in the forward part of the cockpit, a rotten beam and the carlings' ends.  We then checked all the deck around the cabin to make sure it was sound, and resealed the deck.  During this project we were alerted to the rot in the bulwarks, and began making plans to address the issue when Evelyn was indoors.
