St Ayles Skiff World Championships – July 8th to 14th 2013

| 0 komentar |

Doryman hopes to take a trip to Scotland in 2013 to enjoy the festivities at the first St. Ayles Skiff World Championships. Hope you can come along!

Heres the invite that came in the mail today:

"The Ullapool Coastal Rowing Club is delighted to announce that Ullapool has been selected by the Scottish Coastal Rowing Association as the venue for the first World Championship for Coastal Rowing using the St Ayles Skiff. With the astonishing growth of St Ayles Skiff building and rowing by communities internationally the time is right to run a Skiffie Worlds to give an opportunity for Rowers from across the Globe to meet in friendly competition."

"Ullapool, on the banks of Loch Broom, a large sheltered sea Loch in the Northwest of Scotland, is an ideal location to host such an event. With an existing infrastructure developed to cater for the needs of visitors and great community experience in running large cultural events SkiifieWorlds will be well within the capacity of the village."

"Ullapool Coastal Rowing Club together with their partner organisations, the Loch Broom Sailing Club, Coigach Community Rowing and the Ullapool Harbour Trustees look forward to welcoming visiting crews to our magnificent waters. A full programme of maritime and landbased activities and entertainment is planned culminating with the Prizegiving followed by a boisterous Ceilidh Dance on Saturday 13th, 2013."



Its hard to pass up an invitation like that. Ive been promised that there will be "loaner" boats available for international guests who cant bring their own Skiffs.

Let the races begin!

Shallow water skiff shapes ideas

| 0 komentar |

Here are some of my old musings of developing skiff shapes to bring to reality. As I described earlier in my blog of how I like to make a half hull of my vision - idea . I do this after I have done all my weight calculations in advance. Shown are a few past ideas in their growth stages. Sorry but I would love to be able to do this all properly but all I have is the iPad that I got for Christmas this year from my daughters. With out this contraption I probably would not take the time to do all this. Right now it is flat calm with lots of light rain about so Im inside with a fan on doing something. The iPad is great as I can do this stuff with a simple inverter on our sailboat as we move about and post it later. No TV time in my life so have extra time to fiddle here.

So look at the wood half hull against the mirror. The sections are glued to a 1/4" piece of wood,without this it would sit flush against the mirror with the thickness of the mirror being the center line. This is how it was done before 3 D programs . It does make you feel like a peeping Tom though as you stretch around trying to see the whole thing. Each section is drawn out from the center line to scale. Here you can calculate how many cubic inches are in each section. I do not have the side views showing which would tell and show you the distance between each section. It would not show up here very well.
What I will do this summer is draw up 3-4 new skiff shapes from past knowledge with all dimensions easy to draw up to full size hull sections. These you will be able to cut out and install on a simple building jig and from there you will be able to plank up in light cedar strips, Baltec balsa core strips or Core Cell brand planking strips. From this you fair and then glass the outside. When fair, flip over,
remove the forms and glass the insides. Then you finish the inside. To build a deck I will explain all the ways it can be done simply later. I will put this here for free. In the mean time anyone planning on building a skiff needs to read up a bit on strip plank boat building. This is the same as building a canoe; just a little more odd shape and it has a transom. I will get a list of books or pamphlets to look up.
In looking at these shapes it is easy to start to see how many ways and directions you could now reshape and go. Ha, it can be daunting if you do not have a weight list and a clue as to what the finished hull will weigh. Here I come back to having the vision, idea, whatever. Details. 

Of course if you are going to start a new company and you want to follow in the foot steps of something that is already well proven and established then all you really have to do is make a facsimile of it as all the thinking has already been done for you. If you do make it better, and at a better price good for you. 

Now with all the shapes here you still have to decide on which side of the half section line you will put your hull thickness. Makes a difference . Take your numbers from the center line out wards and up to the LWL. This is the quickest way. This method shown here has been used for centuries with the creations of some of the most beautiful boats in the world. Go to see the Herreshoff museum in New port RI. He did all his boats this way. There is not a Yankee boat builder up north that does not know this system nor a Carolina one either. The computer today is the way to go though if you have one.



  Another idea; this shows how you can take an existing boat today and measure or take its lines sections. Without knowing its length between perpendiculars you could stretch this boat out to ......

In this shape here I wanted a good sea boat at rest that would not be as they say here too "cranky" .
It has good freeboard and was a good all round skiff. I lowered the spray rail on this a bit in the bow area when built. Today I would change the stern section aft so this is obsolete in my mind.
 You can see the half sections above and the half hull below. 



Cheap 3 - D rendering 



You can see here how Im drawing in a bit of crown. I like crown a lot. It adds tremendous strength over a flat surface. Also you can gain some Disp. But then you have to be careful where its going to direct the water flow. I do not want crown in my skiff decks as it is a pain in the butt to fit the hatches so the will not squeak and lay flush. 



On this sheet you can see the displacement calculation that I wrote down from a simple lines program that I found on the Internet at the time. I put in all my half section numbers and in a second it spit out all these numbers. I had already done it my old way and every thing was pretty close. In the upper left corner you can see the displacement numbers for three different water lines. This you have to think about a lot as the guys, people that will be in the boat, are most likely going to weigh over 200 lbs.
The rest of the numbers there are just adding up Disp. If I posted all my calculation sheets it would be so boring. But I keep em for reference. This is a heavy skiff at close to 2,000 lbs with all the sports in it.

St Ayles Skiff World Championships 2013

| 0 komentar |
The first St Ayles Skiff Championships are being held at Ullapool in the North West Highlands of Scotland, on the 8th to13th of July, 2013. Last year this time, I expected to attend and was pretty excited about the prospect. As fate dictates, this will not be for me, this year. Im trying to not be too disappointed and to soothe me, the organizers have sent me a patch for my sweatshirt. Isnt that nice of them? Thank you! Apart from the St Ayles being an incredible boat, its the spirit behind this endeavor that draws me to it. Nice people, those Scots.

If you intend to participate in the first World Championships for the St Ayles Skiff, you have just four days to sign up. You will find all the information you need on the SCRA World Championship "Notice of Race" .

A truly novel entrant will be Sephira, also known as The Musical Ark. Sephira was built collaboratively by students and teachers at Moravian Academy, a pre-kindergarten to 12th grade college preparatory school in Bethlehem, Pennsylvania. The vessel is a seaworthy St. Ayles-style skiff, rigged with eight long piano wires from masthead to stern to make it a sea-going harp. The string length and resonance properties of the hull are designed to play notes in the frequency band of whale song.


A $12,000 fundraising goal is currently underway to ship Sephira across the Atlantic. This figure includes $8,000 for the vessels round-trip across the Atlantic Ocean in a 40 foot-container, as well as $4,000 to support the crew of students with travel and accommodations. The Moravian Academy has asked us to help make this epic voyage possible by supporting this project with a donation. You can help by pledging on the Musical Arks Kickstarter page. 






Follow this link to hear Sephiras Whale Song.



This is an independent trip abroad and is not being offered by Moravian Academy. Any student who goes will be accompanied by a parent or guardian.

St Ayles Skiff Doineann

| 0 komentar |




Shortly after this blog began, almost a decade ago, I became enamored of Iain Oughtreds Ness Yawl . The Ness Yawl has taken Doryman readers through many voyages. (If you took the time to follow that link, welcome back!)
In the intervening years, Iain, who was then an internet no-show, has become possibly the most popular small boat designer in the world. And once again I find myself drooling over a new design from the Master, his beautiful sharpie, Haiku.
Shes exquisite, but thats a subject for another day.
While I was writing extensively about the Ness Yawl, Iain designed the St Ayles Skiff. The Scottish Coastal Rowing Association was formed on 29 May 2010, to encourage boat building and rowing and racing of coastal rowing boats along the Scottish Coastline. Communities were encouraged to become involved in the building of new boats to be rowed, principally the St Ayles skiff.

Doryman was quick to promote this extraordinary design and though hundreds of these boats have been built globally, only two St Ayles Skiffs exist on the west coast of the US, Dorymans cruising grounds. Both were built in Portland, Oregon at the Wind and Oar Boat School .

The first boat off the molds at WOBS (Rosie) lives in Portland, rowed regularly by the team of women who built her. The second St Ayles Skiff to come out of that shop was Doineann (Irish for tempest or storm), built for her proud owner, Julius Dalzell. The following update from Julius is the answer to my suggestion that the St Ayles Skiff might make a great sail-and-oar boat, if only she had a sail rig.

"Hi Michael,
It has been sometime since our last communication. As you may recall, Doineann was the second St. Ayles skiff built by the Wind and Oar and Oar School. My wife and I decided upon retirement, in July 2014, to move to a favorable locale, in Cathlamet, Washington for a variety of reasons, not the least being the beauty and boating opportunities of the Lower Columbia River. A significant aspect of our new abode was the availability of a large shop. Today it is a home and restoration facility for small craft.
Of course Doineann is one of the permanent residents. And yes, we did proceed to design and make a sail-rig for Doineann.
Before proceeding with the story, you might be impressed to know that we have a regular crew rowing Doineann, most having little prior rowing experience. We find that performance is outstanding regardless of wind or chop. She slices through anything with little fuss. Totally enjoyable.

We started with an e-mail exchange with Iain Oughtred himself. Iain warned that the craft was designed for rowing, not sailing, and would be tender, so recommended a small lug sail, maybe something around 90 sq. ft.. Iain stated that the existing keel might be sufficient to support lateral stability with minor leeway. He wasn’t sure how she would tack because of her wide turning radius.

We decided to go low budget. After considering many sail designs, our choice was an 85 sq. ft. balanced lug.
The mast was a used item acquired from a builder. Quite the specimen, ugly but it works. A sail was ordered from Lee Sails. I insisted that the sail be mounted without use of fittings or attachments. No screws, nails, brackets or drilled holes. In other words, no intrusions that would impact the original design.

The mast partner we devised uses the kabe support at the forward rowing station, using the kabes and pins incorporated into each rowing station at the gunnel. The mast step slips into the floor boards below. So, on a fine August day, we took to the river for the first sail. In a fresh, accommodating wind, her response was beyond expectations. She went like mad with five adults aboard. The existing steering rudder, though designed for rowing, performed well.The boat was not tender, in fact quite stable regardless of wind on any quarter. We had a ball!

Tacking was a challenge. Because of the long keel, she took her time. Speed would drop off and we would be in irons, propelled in reverse. Throwing the rudder over steered her in reverse through the tack. The sail would again fill and we were off. Too much rudder did nothing but enhance the stall, acting as a brake. The answer to a successful tack was two fold - lots of speed going into the tack, and finessing the rudder. A slow tack became doable.


The materials I used for gaff and boom are too light. Currently another gaff and boom are under construction. Three strips of tight grain fir to be epoxied and shaped.
So, Michael, that is the Doineann story to date. My expectations for the craft are progressing!"



Thank you Julius for that update. Its obvious you love your boat and its easy to see why.
Of course the St Ayles Skiff is a one-design racing machine, so Julius was careful to keep the design legal for racing. He looks forward to the day when more St Ayles are built and racing here in the US. (me too!)







Meanwhile, the Haiku is calling me. Isnt she a beauty?

 Doineann the second St Alyes Skiff launched in Portland

| 0 komentar |

Doineann (Gaelic for "Storm"), a St Alyes Skiff, was launched last Sunday, in Portland, Oregon.
She is the eighth St Alyes skiff built in the US and the second on the west coast.
These boats were built at the Wind and Oar Boat School, a non-profit run by director Peter Crim, by the teams that will race them.


The first boat to come out of the school was Rosie, whose all-woman team will be participating in the Skiffie Worlds next month in Ullapool, Scotland. Rosie joined Doineann on the Willamette River, with Portland in the background, as the new team tested their fine craft for the first time.







Congratulations to the builders of Doineann and also to the Wind and Oar Boat School!
