Form tune up and new build

Time for a winter build, a new tripping canoe. Once the snow flies the sawdust will be flying the shop for a spring launch. The Atkinson Traveller, designed by Rollin Thurlow draws heavily from the early Maine guide canoes, designed for river and lake travel loaded for days or weeks.

Classic Maine shape
 
 Loaded for tripping with , what else, canvas packs

 Nice fair hull


 Form to be tuned up

 New bands are sheared to  2.5", ready to go on after the old ones come off

"
 Loose bands arent the best for building, they create the risk of bounce and tacks not clenching properly

 Nice looking traveller, well travelled and used. Boat has a great vintage look for a newer built boat

 Old wisdom always said not to stand in a canoe, but in Maine and out east wide, flat bottoms in canoes lend themselves to being poled, especially in shallows. 

The Travellers popularity extends to countries where North American canoe culture has many followers, this example is from Germany


All we have to do now is assemble it.....

Modifying a building form

Maine guide canoes are some of the best and most capable tripping canoes, owing to their design dating back to birchbark designs, that evolved into the earliest wood and canvas designs. 
These early shots are from Island Falls Canoe's website, and feature some early Maine guide canoes.
Jerry Stelmok builds some fantastic guide canoes inspired by the early designs of EM White, and others. 


Lots of tripping volume


Guide up high in the stern


Flat mid section for stability to stand, and for poling.


Modern version desined by Rollin Thurlow, named the Atkinson Traveller. 



Great profile and sheerline


Barn find very early guide canoe


All the characteristics of the earliest hulls, circa approx 1890, builder unknown



Atkinson Traveller form



New casters for steel form stand, to roll over all terrain



Shape faithful to the plans, its had 2 boats pulled from it.
To be clear, this is a fantastic, proven design with hundreds of boats built to its design, including being offered by several builders and larger companies. Not wanting to change any of the paddling or load carrying characteristics of the hull, we'll focus on the shape from above the waterline at the bilge on up to the gunwales. The reason is our desire to have a capable tripping canoe with all the characteristics of the earliest boats. Once restored, the early guide canoe will only be paddled for fun or shows, being so old and somewhat fragile. It not be suitable for had trippping or loads. 
The form, while accurate and true, is not particularly well built and will benefit from a rebuild



Tumblehome to be introduced is the major modification to be made





Form displays no tumblehome as designed


Early boat displays lots of tumblehome along its length, and is most dramatic in the centre section.


Hull displays flare, making for a more dry boat is weather and waves. To be clear, our modifications will not enhance the design, but  will will introduce the style we are looking for to try and replicate the earliest boats. A bit of work, but lifes too short not to paddle the boat you want!


Tumblehome all the way forward





Banding as fit to the form is loose, and will be tightened up for better building




A great starting point, and modifications will be made by eye rather than trying to modify the drawings and committing to a full build of the form, uncertain if the modifications were correct. 




Nice long, flat run that is an essential part of the design


Significant tumblehome, but will not alter the water line shape of the hull or compromise its performance.


Ready to be started, this will be saved for the fall and winter 



Sidwinder is a great tool for lifting as well as transferring lines and shapes



Small, elongated early decks and narrow entry that will be used

to be continued this fall...

17' Kevlar tripping canoe

Just picked up a kevlar tripping boat with the wood rotted off, for a screaming deal. Yup it needs new inner and outer rails, decks, and seats and thwarts repaired, and one side is sun faced but its in great shape, no cracks or stars and is the perfect size. Most 16' boats are too small for the load i ask them to deal with between people and gear, and at 35" wide and 13" deep this should be quick. Length = speed, and its a light portage boat too. No we havent given up on traditional wood canvas, but our 18' guide is awaiting restoration and the form is progressing, albeit slowly! 
This will fill in nicely and hey, its got some wood!


The Toyota retrieves another. Really should have kept a count...


Evergreen from Toronto, no longer in production


Ah, race tape - or 100mph tape if you prefer.


Thwart tips are rotted, will make a new one. Teal carrying yoke and a kneeling thwart, a nice touch for solo work 


Nice overall shape, without a lot of damage.


A very nice trick, rather than have the wood terminate awkwardly in the rounded bow profile, they undercut the tip so the wood can go beyond and finish cleanly. 


Resulting profile looks like a EM White from Maine.


The shiny side!


Inside cleaning up nicely


Storage grime and weathered cherry.


Will clean up nicely!


Another nice touch, scuppers on the sides of the decks. 
Carry handles will go back on. 

Next up, rails, decks, skid plates and maybe a white bottom....

21' ash stock will provide the rails.


Ripping rails. 


Making extra sets for wood canvas boats, with the back cut. 


Extra set of hands is helpful to hold down, while being fed. Dont have featherboard attachments for the fence...

Getting ready for another pass. 


3rd and 4th set of hands, courtesy of Kreg (who make some wicked attachments)


Rail stock 


Cherry and ash carry thwart and rail stock 


New Cherry parts, carry handles, thwart, kneeling thwart, decks and seat hanger spacers


Now to remove the old and install the new. First it all gets epoxy sealed before the varnish to prevent rot and turning black with exposure to water.

Old wood out, seats and hangers


Cherry looks great but like all wood doesnt do well season after season exposed to the elements


We've said it before and its always true, NEVER ENOUGH CLAMPS.


Mitred ends sitting in the bow cut out. 


New rails in place temporarily for fitting


Thwart blank in place


New carry thwart, ash and cherry.


Deck rot, new cherry board planed for deck stock.


Taking shape, all parts to be epoxy sealed once fitted to boat, then varnished and reinstalled.


Bow deck, narrower than stern deck so each will be cut separately. 


Cherry for new decks - originals were cherry too...


Wider rear deck


Bow joint waiting to be sanded


Stern Joint


Dry fit


Bow deck


Rather than epoxy we opted for tung oil and 4 coats of varnish, a prettier finish and we wont be leaving this one outside (at least uncovered)


Oiled stern deck and rails


Shaped cherry and ash carrying yoke


Nicer and more colour than epoxy would have provided


Finish sanded




Cherry parts set boat off nicely




Bow deck and rails

Boat is done and awaiting varnish, if it stops raining we can get a full length shot outside!

UPDATE: all done, next up is another fiberglass boat with rotted wood, pics to follow...
