Small Reach Regatta Day 2 in Drake Rowboat

I was a little nervous beginning day 2 on a long reach with a potentially gusty offshore breeze that would carry the fleet 8+ miles to the lunch stop. The cracked mast step was only glued back together last night. Would it hold? This was going to be the same tack that I was on when it snapped. I didnt want to ruin this sail!
While the rowboa
ts and sailboats waited for the whole fleet to be launched and hoist sail for the departure, I
lounged on the floorboards enjoying an egg sandwich made by the caterer who cooks for the event. The food is great and the camaraderie while dining is something I enjoy every year. I saved my sandwich for this moment, laying back on the thwarts in the morning sun watching all the sails around me skitter about waiting for the moment when the lead chase boat would say "every body is in, lets go!".

The sail was east to Flanders Bay where we were to lunch at a bar connecting Ash and Sheldrake Islands (family islands that I arranged for us to have as a lunch spot). The fleet sailed on port
tack on a beam reach for all 8 miles to the stop. It was a hoot to say the least. Drake was right up with all the Caledonia Yawls and other larger sail craft. People were quite surprised to see this long, skinny rowboat pass them or hold position next to boats with much larger sail areas. And to my delight the mast step held.

But this morning was proving something that I try to espouse whenever possible: a rowboat with at least some keel to it can sail downwind quite
fast, but not up wind. And you dont need to ruin
the lines of the boat for rowing and you do not need to add the complexity and drag that a centerboard or daggerboard introduces. Lee boards are simply not necessary for off the wind sailing. Drake has enough stability and keel to even sail without any slippage on a bean reach, and this was a revelation this morning on Frenchman Bay.

The lunch was quick as the tide was eating up the bar -- we arrived a little too late. But the scene was quite spectacular with MDI and Tunk mountain and islands all around. I was the first boat to the bar and the 50 or 60 boats sailing into the bar was just a blast to watch.

The return trip was a 8-mile row to windward, through Sorrento Harbor right by Hancock Point and dir
ectly to Lamoine State Park. Drake showed her stuff by being able to row a steady 4+ knots back to the start line and beat most of the sailboats that had to tack many times to get home. This is what she was designed to do: sail smartly off the wind and row efficiently upwind. If this were a real RAID I would have no doubt t
hat we could be very competitive and with a larger boat for two rowers, probably win. But I enjoy the autonomy, privacy, and relaxation that rowing and sailing alone can bring.

The Perfect Rowboat Sailboat or Both

Do you like the idea of a boat that can row and sail but they often dont like the idea of compromising on one or the other? It is a trade-off. A good sailboats lines are not good for rowing and a rowboats lines are not good for sailing. The latter is true mainly because the hull is quite narrow and fine on the waterline, especially at the ends. A fast rowboats lines just dont provide the stability, often, for sailing and the addition of a slot for the board introduces drag and makes the boat slow for rowing. Wooden Boats long time manager of their boathouse often cites the Joel White Shearwater as an example. Reluctantly, listening to customer demand, Joel White added the centerboard and it really made a difference in the sailing ability: it made it possible. But it also introduced noticeable drag when rowing: the boat was slower under oars. Drake is very similar to Shearwater, only narrower and longer on the waterline, no daggerboard, and therefore faster under oars. Drake sails downwind fabulously because of the moderate keel to provide some lateral resistance and enable excellent tracking for rowing. We dont have a centerboard, so there is no drag induced (though a tight fitting plug for a daggerboard trunk can fair the slot to the hull reasonably well). Ive been asked a number of times, and I just will not add a daggerboard to Drake. She is just a blast to sail downwind and can sail as high as a beam reach quite fast. The sail adds tremendous range when you consider the sail as auxiliary power.

Deblois Street Dory

But if you want to sail upwind, and row well, you need a boat with a lot of flare in the hull and a shape that provides excellent secondary stability. Joel Whites Shearwater and his 18 version of the boat are good examples. Another ideal example is the dory. What I love about the dory is that it is narrow at the waterline and flares out to a generous width, for a rowboat, at the rail, usually 48-5. The Deblois Street Dry is nearly 5 at the rail. The stability this shape produces lends itself to sailing (see photo of me sitting on D St Ds gunwale), but the narrow width at the waterline when the boat is not heeled means that it will row well. The double ended shape of the waterline on a dory keeps the ends fine for rowing ability. Drake shows a similar shape (see photo): narrow waterline, 41" at the gunwales provides secondary stability.

The Marblehead Gunning Dory is, to me, perhaps the perfect boat. If I could have only one boat (lets not think about that...what a shame that would be!), I would have a gunning dory or a Swampscott Dory. Come to my annual Shop Talk & Messabout to see both of these dory types in the flesh and meet two experts on dories: Sam Manning and Walter Wales.

Small Reach Regatta Finishes in Drake Rowboat

This sail is right off a Shellback dinghy, but a new more efficient downwind rig is in the works when we arent making other peoples rigs!

(photos by Christophe Matson in his Goat Island Skiff)

My wife, Ellie Chase, and I finished up a fabulous 3 days of rowing and sailing in Drake along with almost 40 other boats ranging from 12 foot dinghies to 15 sail and oar boats, to 22 foot daysailers. Drake often got to the lunch stops first because we were able to row upwind and sail downwind. It turned out that most of the time we rowed in tandem.

We love this mode of boating for getting around but you have to like to row and be in a good rowboat. And there is no need to ruin the lines of a rowboat by making it be able to sail, as long as you stick to sailing off the wind. We can sail easily on a beam reach down to a run. In the above we maintained 3.5-4kts in maybe 5-10kts total true wind.

The Cruising Rowboat

Some boats just grab your imagination and keeps it working overtime. The Camper Rowboat from Angus Rowboats is just such a boat. Im up way past my bedtime and cant stop dreaming of the adventures awaiting me if I only build this boat!


To understand the boat you need to know a little about the designer. Colin Angus and his wife, Julie, have collectively rowed more than 40,000 kilometers in a variety of oar-powered craft on oceans, rivers and lakes. Julie Angus made history by becoming the first woman to row across the Atlantic Ocean from mainland to mainland. Colin is the first to row across the Bering Sea from Alaska to Siberia, and he has also voyaged by oar down the length of the Amazon and Yenisey Rivers.

They live on Vancouver Island. Maybe I should say they are based on Vancouver Island, from which they launch their adventures. Outside Magazine listed Colin as one of the top 25 "bold visionaries with world-changing dreams" for his work in promoting lifestyle changes to help the environment.

This new boat looks similar to the one the duo used to row and bike 7,200 kilometers from Scotland to Syria. That boat, the Expedition, is a sliding-seat rowboat built for the open ocean with the capacity to store a bicycle and the boats trailer in the main water-tight compartment, making the rower/biker amphibious.


At 19 feet and 175 pounds fully rigged, the Camper is about a foot longer. Instead of stowing a bike, the main compartment is now a bedroom. Other innovations include two small pontoons that attach to the outboard ends of the rowing outrigers while at anchor to make the boat a stable platform for lounging, cooking and sleeping.

Angus says the hull shape of the Expedition and the Camper boat are quite different. The Camper is made from eight panels with a V-bottom. The Expedition is made from five panels and has a flat bottom. Both are beautiful boats and look like they would be a blast to row.




(Note to Colin: Please come up with a better name than "Camper." It congers up visions of eating baloney while seated on the tailgate of a Buick Roadmonster stationwagon. Or, worse, elderly RVers driving a half the speed limit.)

The plans for the Expedition are available now from Angus Rowboats, but we will have to wait until fall for the Camper plans.

This summer Colin will attempt to beat the current circumnavigation record of Vancouver Island, which is just over sixteen days (done in a kayak). He will use an Expedition and figures he will need to cover about 75 kilometers a day in a range of conditions.




My optimum use of the Camper, should I ever build one, would be to row a leasurely dozen or so miles between anchorages in, say, Washington states San Juan Islands. Meantime, the Anguses are planning a non-stop double circumnavigation of Vancouver Island next year with two people in the boat, each taking turns rowing 12 hours a day. (Cant you guys give it a rest; You make me tired.)

Maybe you should rename the boat the Circumnavigator Express. Yah, thats more like it!

A Fabulous 15 foot Rowboat

One of the most unique aspects of the St. Lawrence River Skiff (SLRS) is its hull shape which we believe derives from the bark canoes, at least partly. Both hull forms feature a very fine entry and exit to the waterlines. However, on nearly all the St. Lawrence River Skiffs, their after sections are finer than the forward sections.
The bow of an 18-footer, Annie.

Many rowboats show the opposite, with the aft sections being fuller. The reasoning behind this SLRS hull form regards how the boat trims when under power (oar power, of course). Once the boat is up to speed, the aft part of the hull settles into the water creating a skeg-type effect. A skeg improves tracking of the hull through the water. But by making the hull itself behave as a skeg, we eliminate the extra wetted surface area (WSA in designer speak) that a skeg creates. Any rower knows one tenet of making a rowboat fast: reduce the wetted surface area! This is one reason the SLRS glides along effortlessly with a single stroke of an oar, creating a feeling of flying.

Here is a shot showing the Fry 15 being stripped up. We built the Fry Skiff in 2013 at WoodenBoat using strip-composite construction. A builder by the name of Fry built these circa 1910 in Clayton, NY. The first shot (left) is the bow. The second (right) is the stern view.


You can see (right) how the strips are fairing into the stern with slight concave curvature even before weve stripped to the designed waterline. The strips are not showing this hollow curvature quite yet in the bow (left). This 15-foot model, shows a pronounced hollow even for a SLRS, partly because the boat is pretty short for a Skiff. (In fact, it is the shortest Id recommend for fast rowing. I chose the Fry 15-footer because it is going to be the cartopper in my catalog.)




So this is the fineness or hollow in the stern that I am asserting is a classic feature of the SLRS hull form, making the it such a slippery, fast rowboat.

Two other SLRSs that I am working with, the Bobby at 20 1/2 (which was strip-built in 2012) and Clotilde at 18, are true double-enders, meaning they are symmetrical. So one end is not finer than the other, but their waterlines still show a strong hollow fore and aft. Clotilde is unique because its hull is fairly full in the ends compared to the other SLRS, which has me interested because it may be a faster boat and better in a seaway. So I plan to also model this hull and develop mold kits for Clotilde as well. Bobby mold kits are available.

For the first time, the Fry Skiff is newly updated and ready to cut as a mold kit. She strips up perfectly and produces a hull that is fairer than any hand-lofted set of lines could hope to produce, I dare say. The molds receive a roundovered edge so the soft cedar is not dented. A dado is routed into the molds to make a place for squeeze clamps to hold strips in place. The stems are laminated on fore-aft molds. An alignment batten slots all the molds together in place to ensure squareness and proper spacing. The kit is $750 which includes plans package and the molds.
