Our last extended cruise ended in the fall of 2003 when John and I hauled Morgan’s Cloud in Maine so that we could spend the winter at our house in Bermuda. We had a big decision to make: If we wanted to refit Morgan’s Cloud and keep on cruising, the house would have to be sold. But the house was a little piece of paradise on the water in Bermuda—not something we could afford to replace if we decided later that we had made the wrong choice.
After much agonizing, we decided to continue cruising and so we sold the house in the spring of 2004, moved into a condo with John’s mom, and started in on what we thought would be a one year refit of Morgan’s Cloud.
It is now the spring of 2008 and we have finally moved back on the boat, three years later than we expected. As most of you know, refit woes weren’t the only thing slowing us down, though we had enough of those. Family illness was also big on our agenda.
I have to admit there were many times during the past three years when we questioned whether we would ever get back on the boat. Though two short cruises—one to Newfoundland in 2005 and one to Maine in 2007—kept the goal fresh in our minds, the main thing we needed was perseverance.

So here we are, living on the boat and cruising Maine—the truck we bought for the refit up for sale, our cabin in Nova Scotia (welcome haven during the last three years) well looked after by friends—working out the kinks that always appear after a major refit. And looking forward so very much to the people we hope to meet, the friends we hope to see again, the places we want to revisit and the new places we want to explore.
The moral of this story? Yes, we are ‘fortunate’ to go cruising but we aren’t ‘lucky’ (drives me crazy when people say that!). We’ve made some difficult decisions, given up some shore-based comforts, and worked very hard to make it happen. You can too if you want.

Risk Management, Hurricanes

Question, received July 11, 2008 [edited for brevity]: We’re in St. John’s, Newfoundland, waiting to cross to Scotland. We’re just about ready to go and the weather forcast is good for leaving. However, hurricane Bertha is just south of Bermuda. The current forecast is for her to weaken to 55 knots within four to five days, and stay well south of Nova Scotia and Newfoundland.
It seems possible for us to go now and if Bertha speeds up and heads northeast we could head for the Labrador Sea to get out of her way. Would you consider leaving a stupid choice to make?
Answer [with some changes and additions after the fact]: This is a tough decision, particularly since the weather, aside from Bertha, looks very good to head east and the summer is marching on with an eve-increasing chance of hurricanes. If I was in St. John’s in Morgan’s Cloud and absolutely had to get to Europe this year would I risk going? Perhaps, but as a general rule I don’t run with the bulls and I don’t go to sea in the same ocean as a hurricane. To me, the downside risk of both activities outweigh any benefits.
If I was heading for Greenland I would go but watch Bertha very carefully and divert for Labrador if she did something unexpected. However, on a course for Scotland you won’t realistically have that option after the first day or so.
Hurricane prediction is an inexact science at best. There is always a chance that a hurricane will do something completely unpredicted, particularly when it goes extra-tropical as it moves north past Nova Scotia. It, or an extra-tropical storm it spawns, could also easily accelerate to 25 or even 40 knots and overtake you no matter what you do. Admittedly, with the current jet stream position I’m guessing that Bertha will probably eventually die out north of Bermuda, but can you afford to take the risk of that being wrong? Only you can say. And before deciding, you need to ask yourself if you, your crew and your boat are capable of surviving storm force winds for several days.
Additional Thoughts: As hurricane seasons have got longer with more frequent and intense storms that come further north earlier, it is getting more and more difficult to completely avoid going to sea with a hurricane around and still make voyages.
However, there are two things voyagers can do:
1). Leave for west to east Atlantic crossings by the end of June.
2). Be prepared to scrap the entire plan of making the crossing if stopped from leaving by a series of hurricanes, and go the next year, but earlier.
Electrical systems and aluminium yachts

Two green lights and all's well
All of the yachts I have sailed over the last twenty years have been simple boats with fairly minimal electrical equipment. Not one of them (even up to 80ft) had an autopilot – sail training vessels often don’t, as they are set up to be sailed “handraulically” as we say over here.
So when we approached the planning for Pèlerin, we were mindful of our desire to have a simple boat, yet at the same time capable of meeting our wish for self-sufficiency at sea or in harbour. Another factor also nagged away in the back of our minds – the risks of electrolysis with aluminium, a subject upon which we’d heard a great deal of negative comment.
There is no doubt that there are risks inherent when mixing electricity and a material like aluminium, but we reasoned that Alubat have built thousands of OVNI’s over the last thirty years, and we’ve never heard of one disappearing! So we did our homework, and made a few changes, and trusted the builders to do the rest. Now that we have her afloat and working, we can make some initial comments on what we have found.
The first thing is that the wiring installation has been done with great care at the factory. OVNI’s, like most alloy yachts have a two wire insulated wiring system, which means that there is no earth to the engine or hull as in a more conventional GRP boat. Each wire goes out and returns to the positive and negative sides of the battery bank. As a result, extra care has to be taken to ensure that there can be no grounding to the structure of the boat that would set up a galvanic circuit. Every OVNI is fitted with a leak meter, which can be used to make a daily check that no stray currents are making their way to ground and thus compromising the boat. If when tested, there is any sign of a leak from either the positive or the negative side it should be possible to identify which circuit is at fault by working through every switch on the panel in turn to identify the circuit, and then setting about finding the leak itself wherever it is in the wiring.
This was very useful when it came to wiring up the new electronics such as the autopilot and the radar, as after each item was fitted the leak test could be conducted to ensure that no fault existed as a result. All electronic units had to be isolated from the hull structure during installation, once again to avoid any chance of leaks to the boats structure. We did, in fact, have a small problem during installation, which was traced back to a faulty AIS unit and rectified, so the leak meter is a vital component on this type of boat.
Another area which we approached with caution was the shore power circuit. Having heard of (and seen) the effects of galvanic corrosion on boats kept in some marinas, we were particularly aware that this was an area for concern for us. Not that we intend to base Pèlerin in a marina, but who knows where we may decide to overwinter her at times. We finally opted to fit an isolation transformer, a device that it is virtually unknown in Britain, at least, but by all accounts is common in the USA, and should be fitted to all metal boats, not just aluminium. Of course, we may never know just how effective the transformer is – if it’s working then we should see no problems, and I don’t suppose we shall turn it off to find out otherwise! It is a heavy and costly item, though, so we hope that it will prove its worth.
So far we are well pleased with our new home. Not that we haven’t had our share of glitches, but these have been overcome with support from the Agents. We have had her out in a maximum of 30 knots of wind so far, when she was stable, comfortable and easy to handle, so we’re looking forward to our first decent passage in her very soon, when we’ll be able to report back in far greater detail on our impressions.

Hard Dodgers, Another Option

Very experienced live aboard voyagers Lane and Kay Finley sent along a detailed description of their hard dodger, complete with photographs. The advantage of theirs over ours is that it is all hard with glass windows; much stronger and pretty much maintenance free. On the other hand, I like the larger expanse of window, fewer blind spots and curved shape of ours. Just goes to show that everything on a boat is a compromise.
Many thanks to the Finleys for sharing the information below:
"In the end, we designed and built our own hard top, using foam-cored fiberglass construction to achieve strength and lightness. The finished project is strong, safe to stand on, gives excellent visibility through GLASS, doesn’t ruin the lines of the boat and provides amazing protection from the weather.
Our navigation electronics now live under the hard top where they are protected from the elements and much more user friendly. We have also noticed that we get less ‘salt air’ inside the cabin.
Before undertaking this project, we took pictures of dozens of hard tops on boats that we saw sailing in New Zealand waters. The New Zealanders are well aware of the benefits of hard tops and you can see all sorts of creative designs in every port.
Since we consider our Annapolis 44 to have fairly elegant lines we were very cautious to adhere to a complementary design. After many drafts, we finally drew the final design to scale and then lofted the plans on our garage floor. We built the mould out of MDF plywood with inserts for the windows so that the 10mm safety glass would end up being set-in against a solid fiberglass lip and be flush with the exterior surface of the hard top.
This was a ‘female’ mould, so the interior surface was sanded smooth and then waxed to prevent the fiberglass resins from sticking to the mould. We laid up the required layers of fiberglass cloth and resin in the mould, and then placed the foam core (30mm medium density) over the fiberglass layers. At this point we laid up more fiberglass to the design specifications and ‘sandwiched’ the foam in place.
High Modulus, a composite engineering company in Auckland, made some recommendations for the engineering specifications.
The finished product, which also includes a dome light and reading lights in the ceiling, was fibreglassed in place and we re-painted the deck to finish it off. It has proven to be an excellent addition to the boat and cost approximately US$3000 in materials to build. Of course that does not count our labour. However, it was an interesting winter project and one that we are very proud of.

Our Hard Dodger, Third Time Is The Charm
posted by John & Phyllis
Web Site
Question: [edited for brevity] I notice from pictures that you have a hard top dodger and bimini on Morgan’s Cloud. Who designed and built those? Was it expensive? Any pit falls to avoid? Also, I am thinking of trying to be environmentally friendly and loading mine with solar panels, what do you think?
Answer: What you see is our third crack at creating the "ideal" dodger and bimini top, at least for us. I can’t say that “design” is the word that I would use, more like "evolution".
When we bought Morgan’s Cloud she came with a fabric dodger set on heavy duty (1-1/4”) stainless steel bows. When that came to the end of its life we decided to stay with the basic shape and design, since it had worked well, but make the dodger top hard. We also decided to add a bimini top to try to reduce the crop of growing things that dermatologists delight in burning off my (John) skin.
In designing the bimini our first concern was that we not compromise access to winches or other sail handling equipment and to preserve good visibility. To us, turning a boat’s cockpit into a completely enclosed sunroom with curtains all the way around is a bad idea. And unnecessary: even in the Arctic with temperatures hovering around freezing we have not had a problem staying warm as long as we are protected from the wind and dressed properly.
We also decided to end the bimini forward of the wheel since we rarely steer and when we do we like to be able to look up at the mainsail. We do have a cloth addition that attaches to the aft end of the bimini and goes to the boom gallows to provide shade when the sun is aft.
Since the existing dodger bows were so substantial, we used them for the basic structure, although with a modification: The curve of the old fabric dodger had required us to keep our heads bent slightly forward when sitting under it. It is truly amazing how uncomfortable this can be on a long watch. To solve this problem we had a short piece of tube welded into the middle of each bow to move the curve outboard by 2 inches. This has had a miraculous effect on our comfort.
Before making this change we made sure that we would still be able to see the oncoming waves and the headsails, while sitting in a comfortable steering position and looking along the side of the dodger.
Ideally, we would have liked to make the whole dodger rigid including the windows. However this would have necessitated going to glass or plastic windows without curves, which would have compromised the boat’s looks to a level we could not tolerate. We did enquire about a custom curved laminated glass windshield; however, when the $10,000 figure was mentioned by the manufacturer, that was the end of that discussion.
We have no window material between the dodger and the bimini since if we can’t see properly through the dodger glass due to spray or condensation we want an unimpeded view when we stand to look over the dodger.
For our first hard dodger and bimini top we went to a mass producer of fiberglass tops for both. This was not a success. The fiberglass laminate was too thin, resulting in alarming flexing underfoot. Since being able to stand on the dodger to furl the mainsail or tie in reef points was a lot of the reason for going with a hard top in the first place, this was not acceptable, although it did last 4 years before developing cracks.
The other problem was that the extrusions provided to attach the fabric sides and front were really chintzy and poorly designed so it was impossible to keep the joint between the hard top and fabric sides waterproof. Aside from the discomfort of having constant drips, we navigate on deck under the dodger so leaks resulted in soggy charts and publications—very irritating.
For our third iteration we stayed with the same design but had a custom glass shop build the hard dodger top using a balsa core sandwiched with fiberglass. This resulted in a very stiff and relatively light structure, albeit at vast expense. After the custom shop finished their part, we covered it with Treadmaster, painted it with Allgrip and added good quality plastic extrusions, glued with Plexus adhesive, tucked well under the edge to prevent leaks.
At the same time we laminated a piece of ¼” plywood to the underside of the bimini, to stiffen and strengthen it, as well as adding Treadmaster to the top.
Finally, we had the new dodger front and sides fabricated in one piece with no zippers. We think that zippered windows in dodgers are a mistake since they result in blind spots and they will inevitably leak. Of course, those in hot climates may disagree, but we have never found the heat under the dodger excessive, even in the Caribbean. For fabric we went with Stamoid rather than the Sunbrella that we had used on previous versions.
These have proved to be good changes and combined with the well recessed tracks have made the dodger completely waterproof, even when punching to windward with the spray flying.
We have considered solar panels but are loath to add them since the clutter would make the bimini much less functional to stand on when sail handling.
The devil is in the details. Note how the hard top overlaps the fabric top edge, which slides into a plastic extrusion on the front. To attach the sides, there is a light fiberglass batten in a pocket that is through bolted to a rabbited-out lip, to clear the bows, on the underside of the hard top.

New Attainable Adventure Cruising Web Site
posted by John & Phyllis
Web Site
After three months of evening work (it made a nice change after a day of boat work) we have just uploaded a complete new design for our Attainable Adventure Cruising web site.
Our goal in designing the new site was to make it easier for you to find both specific information of interest to you, as well as content added since your last visit.
You can now access pages in two ways: from the topical menus on the left side (anchoring, mechanical, rigging & sails, Greenland, Newfoundland, etc) and from the menu across the top by information type (questions & answers, stuff that works, rants & musings, etc).
To make it easy for you to find pages you have not yet read, links to these pages are in dark blue and change to red when moused over. Links to pages you have read change to light blue in all menus, regardless of where you accessed them from. Note that if you clear your browser history between visits (some browsers do this automatically after a set number of days) all links will revert to dark blue.
We will continue to post all new information to the “What’s New” area powered by Blogger and then on a regular basis move it to the main site. To assist you in keeping track at a glance, our three most recent posts are listed in the top left corner of the site together with the last date that posts were archived.
We are also providing three ways for you to be automatically notified when we post new content.
Let us know how well we have achieved these goals by adding a comment to this post or contacting us directly. We welcome any and all suggestions for improvements to our web site.
The Gulf Stream
posted by John & Phyllis

A friend of ours, who is a cruise ship captain, sent along the following list of links to everything, and I do mean everything, you have always wanted to know about the Gulf Stream. Some interesting stuff.
Our friend is on the New York to Caribbean round trip run. Apparently the pay off for him for getting the Gulf Stream right is a few more precious hours to effect the change over in New York of several thousand leaving and incoming passengers. Who knew? I guess the company is pretty happy about any fuel savings too.
It seems like a good day to post this list since a whole bunch of ocean race navigators, who will have been studying this stuff, and much more, for weeks, will be starting the Thrash to The Onion Patch tomorrow, each with his or her own theory of how to get to Bermuda the fastest.
I guess I kind of miss the race, judging from the amount of time I spent flicking through this stuff.
