In the previous episode, Mark sailed his Cape Dory 36, Swan, solo from Morocco down to Mindelo in Cape Verde. Now on the return leg of his Atlantic circuit he faces the big one - the 2,200-mile trade-wind passage across the Atlantic to Dominica Island in the West Indies. There is no diesel engine. Only a small 6kw electric outboard motor in a custom lazarette well used mainly to enter and depart port.

This is a design overview and specifications breakdown of a custom, versatile tandem-axle trailer for transporting your own fixed-keel sailboat in the 26 to 32-foot range (such as the Pearson Triton, Alberg 30, or Cape Dory). Rather than a fabrication or welding tutorial, this video focuses on the structural dimensions, design logic, and the telescoping riser support system that allows a single trailer to safely match and adjust to different hull contours. The info in this video will assist you in ordering a similar trailer with correct specifications or can be a starting guide for building your own trailer. Below are the general specs for the trailer: 1. Lift-off type, tandem 7,000lb drop axles, both with electric brakes. 2. 14,000 GVWR construction, 7" channel, 2 5/16" ball. (You might notice the tag on the trailer states 12,500 lbs. We derated it so as not exceed the weight I’ll be using with my Class 5 ball-type hitch, and to stay within private-use registration tiers. Consider it a built-in safety factor.) 3. 7,000lb fixed tongue jack welded to frame (not the lighter swivel type). 4. Extendable nesting hull support channels and screwpads on threaded rods with 6 side supports placed outboard as far as possible (see sketch): Single bow center riser 26" long overall, 74 degrees. V screwpad at bow on sliding base held by U-bolts with extending riser channel. Two forward side supports risers 28" overall, 82 degrees. Two center side risers 28" overall, 90 degrees. Two aft side support risers 34" overall, 82 degrees. 5. Main 7” U-channel frames to continue forward within 8” of tongue for best support. 6. ST235/80R16 Range E tires or equivalent with spare tire. 7. Primer and black paint. 8. All galvanized fasteners. 9. LED lights. 10. Treated wood for screw pads and bed. I’ve included a sketch in the video to give you a clear sense of the dimensions and layout.

In this Cape Dory Refit Part 7, we modify the galley to better suit a minimalist, off-grid setup. In a previous video we covered the conversion from bulky propane stove and oven to Origo alcohol stove. Now we’re removing the original built-in ice box and drawers to create a custom locker to house a removable portable fridge/freezer and a dedicated 12V battery supply, providing better efficiency and more versatile storage. A portable fridge/freezer keeps it compact, affordable, and easily replaceable rather than trying to maintain a built-in unit.

Cape Dory sailboats are often prone to leaks at the hull-to-deck joint, which can occur both at the teak toe rail fasteners and where the glued joint edge has degraded. Sealing this area from above is a huge task; it requires either fiberglassing over the entire toe rail and then repainting the whole boat, or removing the rail entirely to glass the joint and reinstalling a rail - which still leaves you with potential leak points at the new fastener holes that could leak. Instead, to save some labor and ensure a seal, here in part 5 of this Cape Dory 30 Refit series we make this deck joint watertight by fiberglassing it from below deck. This internal approach creates a permanent bond without the need for a total exterior refit. By choosing this method, we still have the option of keeping the original toe rail in place and adding some height to the worn down rail by laminating another piece of wood to the top and finishing it with a durable accent paint rather than high-maintenance varnish. If you have other techniques for tackling these joints or any questions about the process, let me know in the comments.

Here in Solo Sailor Atlantic Circuit Part 4, Mark and his modified Cape Dory 36 Swan continue their circle cruise of the Atlantic, sailing in November 2025 from Agadir, Morocco to Mindelo, Cape Verde. The next leg will be his return trans-Atlantic passage to the West Indies. A unique aspect of his voyage is that for auxiliary propulsion he is using a tilt-up 6kw electric outboard in a custom built well in the lazarette locker. Since it has very limited range he mainly uses it only to depart and enter harbor. On this passage he had persistent trade winds behind him and only a few hours of light winds so he did not need to motor at all once he cleared the harbor.

DIY Retractable Solar Panels on Speed Rail Arch - Cape Dory 30 Refit Part 4. To maximize solar power in the restricted space on this 30-foot Cape Dory cutter (with electric propulsion), we designed this no-weld/no-bend method for a DIY retractable solar array arch built from Speed Rail fittings, aluminum pipe, and heavy-duty stainless-steel drawer slides. The two extendable panels stow flush under the two fixed upper panels while maneuvering in a marina or for low windage when sailing offshore in heavy weather. They slide out on tracks to deploy when needed at anchor or in moderate conditions offshore. The arch is done but the wiring will be covered in a future video. Subscribe to follow the refit. For more sailboat projects, visit AtomVoyages.com Parts List: Eight pieces 6463-T66 schedule 40 polished anodized 1.25" pipe sold in two pieces 23' stock length. (we used about 36' total) $270 total. It's easiest to cut the pipe and angle on a chop saw but you can also cut it with an angle grinder or hack saw. We purchased two pieces 1.25" polished 6463 grade aluminum schedule 40 pipe in standard 23' lengths from our local wholesale supplier. At $135 each it was cheaper than ordering 8 pieces of cut lengths online. Bright polished anodized aluminum pipe is twice as expensive as 6061 non-anodized and if you don't have a local wholesaler then anodized pipe cost could be prohibitive, which is why most DIY builds choose non-anodized. In that case be prepared to let it weather into that dull oxidized appearance. Note that pipe (like this Schedule 40) is measured by its Nominal Inside Diameter (ID), while stainless steel tubing is measured by its Outside Diameter (OD). This 1.25-inch pipe has an OD of 1.66 inches. If you’re building a larger arch, you'll want to use 1.5-inch pipe (1.9" OD). We used Schedule 40 because it’s plenty strong, lighter, and less pricey than heavy-walled Schedule 80. Two pieces 6061-T6 3/16" x 2" x 62" angle bar (NOT anodized) sold in one piece 25' stock length $87. Anodized angle bar is hard to source and in this build it is not in a highly visible area so doesn't matter if it becomes oxidized on the surface. A stock 25' piece of angle bar is double what we needed but at $87 it was cheaper than buying two shorter pieces online. And we can use some of the leftover on other projects. Speed-rail fittings: 1. Four pieces 1.25" Tee-E $16.48 each https://www.buyrailings.com/shop/variant/07060-5e-tee-e-aluminum-magnesium-1-1-4-ips-12794 2.

Because these are N-type bi-facial, shade tolerant, and wired in parallel, they will cope with partial shading better than standard single-sided P-type panels. Clamps and fasteners: We used two Garhauer Dinghy Davit Stern Rail Clamps 1″ to 1.25″ DD-SRC 1-1.25 $75 each. These tube clamps are not a perfect fit to 1.25" pipe but are still useable. You can special order these clamps for 1.5" tube for a better fit (model DD-SRC 1-1.5) or look elsewhere for different style cheaper clamps.

Mark continues his travels on his modified Cape Dory 36 Swan on the third leg of his Atlantic circle cruise, sailing from Horta, Azores in June 2025 to Praia da Vitoria on the island of Terceira. On August 25 he departed Azores for a 5 day passage to Porto Santo (Madeira). After a brief layover he made a passage to Agadir, Morocco in just under 4 days, completing his first Atlantic crossing. The next leg will be his passage from Morocco to Cape Verde. A unique aspect of this voyage is that for auxiliary propulsion he is using a tilt-up 6kw electric outboard in a custom built well in the lazarette locker. Since it has very limited range he mainly uses it only to depart and enter harbor. For more videos on preparing his boat for this voyage, check out the Cape Dory 36 Refit Playlist on this channel.

The Sandpiper 32 is a fiberglass round-bilged Sharpie, of which 17 were reportedly built by Marine Innovators in Florida. Designed to carry 1800 lbs. of iron ballast sealed in 200 lbs. of polyester bonding filler in a molded fiberglass grounding shoe which is integral to the hull and fiberglassed over inside the hull. The remaining 500 lbs. of recommended ballast (gear) is carried inside for trimming.

SAIL AREA (for CAT SCHOONER) 363 sq. ft. DRAFT - boards up 19" (we measured it as 24") DRAFT - boards down 4'6" Inboard electric propulsion system: https://www.annapolishybridmarine.com/thoosa-inboard-systems.php Below is designer and builder Walt Scott’s description of the Sandpiper: SANDPIPER has evolved from over 45 years of designing and sailing shoal draft boats. In addition I have spent many hours over the writings of Chapelle, L. Frances Herreshoff, Beebe, Colvin and other devotees of the sharpie. Finally, Munroe's. "THE COMMODORE'S STORY", and Gilpin's, "THE GOOD LITTLE SHIP", convinced me that what I needed for my own cruising boat here in the shoal waters of the west coast of Florida was a scaled down version of the Commodore's PRESTO. PRESTO was the first of a long line of round-bilged sharpies designed by Commodore Munroe for use in general transportation and salvage operations in the shallows of the Florida Keys from the 1880's into the twentieth century. They were derived from the original flat bottomed sharpies used for oyster tonging off New Haven in Long Island Sound. The long narrow flat bottom work boat existed in various forms along the entire Atlantic coast and around into the Gulf. They were easy to move with oars before the gasoline engine existed; their rigs used simple unstayed pole masts; they could carry a heavy load with little draft; they could be beached without damage; and they were inexpensive to build. A SANDPIPER hull is very similar in lines to PRESTO except that it displaces 7400 lbs. on a 28.3 ft. waterline instead of 17,000 lbs. on a 35.5 ft. waterline for PRESTO. This makes for an easier boat to move around on land and take home for winter storage. PRESTO carried 4 ½ tons of inside ballast. SANDPIPER carries 1800 lbs. of ballast sealed in 200 lbs. of polyester bonding filler in a molded fiberglass grounding shoe which is integral to the hull and fiberglassed over inside the hull. The remaining 500 lbs. of ballast (gear) is carried inside for trimming. The low ballast center of gravity combined with the light weight rig and the low cabin profile result in a positive righting moment even in a 90 degree knockdown. PRESTO carried a large heavy centerboard which took up a lot of space in the cabin. SANDPIPER instead has two bilgeboards which swing into trunks which are integrally molded into the hull under the berths. The use of bilgeboards not only eliminates the internal space problem but it reduces the vulnerability of the slot to damage or jamming from grounding. Sharpies, being long and narrow, favor a divided rig to get sufficient sail area along with a low center of effort and a low rig center of gravity. The SANDPIPER rig is a cat schooner rig with unstayed masts of aluminum. [This boat is a schooner but not unstayed cat rig]. One of the disadvantages of the sharpie has always been lack of headroom. With the relatively narrow and shallow hull it is necessary to keep the cabin weight low to maintain good stability. With the help of the arced bottom I have been able to attain a minimum of 5 ft. head­room in SANDPIPER. For additional headroom at anchor, a tight fitting pop-top spans the main cabin area, providing 6 ft. of headroom or even more if required. A seal around the sides can be fabricated of vinyl coated cloth with snaps and Velcro bug proofing.

After a year long refit the Cape Dory 36 Swan is complete and sets sail for a three month cruise to Bahamas and then back to Brunswick, GA briefly. In July they head north offshore some 900 miles to New England with one stop at Cape Lookout Bight, NC.

We test two portable gas generators - The Honda EU2200i, which has an 1,800 watt continuous run rating, on a Cape Dory 27 sailboat to charge the 48v lithium battery bank that supplies the 3kw electric motor - and the cheaper Powersmart 2500, which has a 1900 watt continuous run rating on a Cape Dory 36 with 6kw motor. Honda EU2200i 2200 Watt Portable Inverter Generator https://www.amazon.com/Honda-2200-Watt-Companion-Generator-Co-Minder/dp/B08YJP5HC7/ref=sr_1_1?th=1 Powersmart 2500 watt portable gas generator https://www.amazon.com/dp/B089FDFDH5?th=1 Accessories: Regardless which model generator you select you may want these two accessories. Other than the typical 15A household extension cord one item you will need is a neutral to ground adapter plug that you plug into one of the AC outlets on the front of the generator. This is needed to prevent the generator shutting down due to wrong polarity if you plug the extension cord into your boat or RV shore power inlet rather than running it direct to the appliance you want to power. The other item you might need is a 15A male to 30A female adapter for connecting standard household extension cord from generator to boat's shore power receptacle.

The modifications to this Cape Dory 27 "Ma Ha" Voyager Edition sailboat were completed in 2023 by Cruising Yachts Services in Brunswick, GA. Voyager Edition is used for boats we have gone through thoroughly top to bottom making repairs and modifications to make them more suitable for offshore voyages, including new sails from Rolly Tasker National Sails, new rigging, self-steering, integral water tanks, collision bulkheads, plumbing, electrics, ground tackle, and many more. Check the Cape Dory 27 playlist for more details of the projects shown here. Our sea trials on the ePropulsion Navy EVO 3.0 electric outboard motor and Tohatsu 6 hp Sailpro gas motor showed the Tohatsu pushed the boat at 5.6 knots. We gained about a 1/2 knot from when it had an inboard diesel engine by not dragging the inboard prop and by eliminating turbulence by filling the prop aperture in keel and rudder. The increased rudder area by filling the aperture enhances the steering. The electric motor gave us 5.15 knots top speed which is not quite as good as the 6 hp Tohatsu but still acceptable since our goal was at least 5 knots. The graph in the video shows the speed/watts/range results which show that the range with one 80AH battery is between 6 to 21 nautical miles depending on throttle setting. The regeneration under sail was disappointing. In our first test we got 45 watts battery charging at 4.5 knots sailing speed but more typically we got less than 40 watts at 5 knots boat speed. Despite the success of our modifications this is not intended to be an endorsement for replacing your inboard diesel with an outboard motor. We have significantly less power available to push into wind and waves. The top speeds we achieved above 5 knots will fall off quickly when going against headwinds and waves. It is intended as a low power alternative propulsion system for keen sailors rather than the more common motorsailing yachtsman who only raises sail when convenient. It takes about one hour in calm waters to swap out the electric and gas motors so it's not something you want to do frequently. But the option is there when needed. We envision using the electric for most situations but swapping to the gas motor for long trips in waterways or in the Panama Canal. Dual propulsion systems also serve as a backup in case of a breakdown. Another downside is the quality of the Epropulsion components we recieved and some issues with the design features. Within a few hours of testing the E80 48 volt lithium battery became faulty as well as the remote throttle diplay. Both were replaced under warranty after lengthy delays. Quality control should be better.

How to charge both 12-volt and 48-volt lithium batteries from 12-volt solar panels using transfer switches. Note: Because these transfer switches are rated for AC current only, over time with repeated DC switching under load the switches could become faulty. Once the switches are on they have no issue carrying the current, it's just that in theory, switching them repeatedly under load over time may damage them. My feeling is that because 200 watts of solar is a low arcing resistive load rather than the higher arcing inductive loads of say an electric motor, that there is no problem. But to ensure that does not happen, the transfer switches should only be switched when there is no solar output on them, such as at night or during daylight by placing a sheet over the solar panels temporarily. Another way to do it is to install an on/off switch on the solar input positive line before it reaches the transfer switch and then turn the input switch off temporarily to change the transfer switch.

We replaced the old diesel inboard engine with an electric drive motor while also having a gas outboard available to extend range when needed. We tested the Epropulsion Navy EVO 6.0 electric outboard motor and Tohatsu 9.8 hp extra-long shaft gas motors on a Cape Dory 36 sailboat of approx. 17,000 lb loaded displacement. The Tohatsu 9.8 pushed the boat at 5.9 kt in calm waters. We gained about a 1/2 knot over an earlier test by not dragging the inboard prop and by eliminating turbulence from the prop aperture. The electric motor with composite low pitch (high thrust) prop gave us 5.7 kt top speed. Not as good as its advertised 10hp gas motor equivalence but still acceptable since our goal was at least 5k. The electric motor is 15 lbs lighter than the Tohatsu. The high pitch (low thrust) prop gave us 5.35 knots which is about 6.5% slower than the low pitch prop.
