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.

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.

Phoenix III and the Perfect Customer

Mist on Lake Cootharaba -courtesy Paul Hernes
Sometime early in 2005, a fellow walked into my workshop in Brisbane, Australia. At the time we were extremely busy with a number of boats under construction, and I remember that I was unable to attend to the visitor for quite a while. He had told me that he wanted to look at a boat we were building, with the intention of purchasing a set of the plans for his own use. His name was Paul Hernes, and he appeared to be typical of the sort of amateur builder who frequently came to the shop.

In those days the telephone would ring constantly, and I had to leave Paul to his own devices for five or ten minutes. While he was waiting patiently, the visitor wandered around the workshop, and struck up a conversation with my friend, Doug Laver, who was working on one of our jobs. Doug is a man of action, and after listening to Pauls story he said that he should abandon any idea of buying the plans he had in mind. Doug told him confidently that he needed a better boat, and said, "...Ross will design it for you."

Now, Dougs promise was made with the very best of intentions, but the problem was that I didnt have any idea the the promise had been made!


For quite a long time I had been drawing designs as a method of educating myself. Despite a lifetime of reading about boats and boat design, I still didnt know anywhere near as much as I wanted to about the design process. I began my design work as a strictly private affair to help me better understand the work of the designers  from whose plans I built. But a promise is a promise - Doug and Rhonnie were both of the opinion I could do the job, and Paul Hernes didnt know of my misgivings.

Designing a boat - at least one with detailed drawings, rather than just a set of lines or a 3D model - takes up an enormous amount of time, and time was something I had very little of in those days. We were working fourteen hours a day, six days-per-week, and after work I still had to do all of the accounting, ordering, and invoicing. Consequently, Pauls new design was done in very late-night sessions, and I had to feed him the drawings one or two at a time. The instructions - other than some notes on the plan sheets - were verbal, and delivered over the telephone. (These days there is a fifty-page instruction manual with the plans).

To cut a long story short, Paul Hernes turned out to be one of those rare people who have intelligence, patience, good-humour, and initiative in equal measure. Despite having only built a tiny pram dinghy by way of past experience, Paul had the very first Phoenix III done in about five months.

Time and again I have explained to people that the thing to do when building a boat is just to get on with it, and most of the thousands of questions which fill up your mind at night time will be answered by the job itself. What is needed is what Paul displayed so very well - common-sense and initiative.

Well, it is now six years since the first Phoenix III was launched, and Paul has sailed her on an average of once a week for that entire time - sometimes he sails much more frequently, and occasionally poor weather keeps him off the water for a little while. But I have met few people who use their boat more consistently (yes, Rick, I know you do too...)

Paul and me about five minutes after the very first launching under sail. The crease in the mainsail is because the brand-new snotter line had stretched, but she was going nicely anyway.

That is me testing her stability on launching day. Very good for such a slim boat.
Paul repainted her a while back. Here she is showing her new hull paint and her optional balance lug rig.
As the above photo shows, you can rig Phoenix III in a number of different ways, using the same mast and the same mast step and partner. There is even a Bermudan rig which requires stays - but it still uses the standard mast step and partner. Being able to swap rigs without carrying out any modifications to the boat is a distinct advantage, particularly if you are interested in cruising as well as day-sailing. I took great care to proportion all of the rigs to allow for proper hull-balance while still using a standard mast stepping position.


There are plenty of examples of Phoenix III around now - this is a nice one sailing on the U.S. west coast

Since Paul finished his boat there have been a lot of other examples of Phoenix III launched. At the time I designed her, I had decided that the ideal size for a beachcruiser which would carry one or two people, be a pleasure to row, and be light enough to manhandle onto a trailer when operating alone was somewhere around 15ft long and with a breadth of 4-1/2ft to 5ft. I have not changed my opinion.

Since the first day when Paul walked into my workshop, he has become a good friend and an inspiration to me and to many other sailing people in this part of the world. It is largely due to him that Phoenix III has become such a success. Paul has quietly and steadily worked over his boat, developing the running rigging and making small alterations to his stowage arrangements etc. This is how things should be - a boat used frequently, maintained well, and developed so that the combination of skipper and boat become a smoothly-functioning team.
