'Octavia' and 'Katie's fore-feet are, to all intents identical. The sides on 'Octavia' are also exactly the same cut - actually all eight pieces, hence the name, which is also repeated on the after end*, whereas on 'Katie' the 'sides' fore and aft are rather different and only identical end-for-end:
*On each boat, be sure you understand which edges form the keel, which the chines and which the gunwales, otherwise you'll end up with a humpback whale, or a striking slug, or something worse. They are marked on the plan, but if you are not sure, I'm just out here in cyberspace, itching to make sure you get it right.
The plans show a flatish under-section for the stern on 'Katie Beardie' which are to provide extra buoyancy for stores and to iron out the wake at any speed and were plagiarised straight from the International Ten Square Metre Sailing Canoe.
In either case, if a single frame midships is set up with full in, or out-wales, then the hull will tend to take on the correct shape, though a few props between the wales will produce a better curve which you can push around until you like the shape; personally I prefer something slightly beamier a tad aft of amidships. I would be happy to provide the midships sections of either if anyone wants to take this further.
To make a paddling canoe, you could use two front ends of either design, but I think mixing one with the other could prove disastrous. Note that the the hull on both boats comes from just the two sheets of 4' x 8' ply.
Apologies Tom - I edited the posts as you requested in your email, but a few things went wrong. Luckily I have the original messages:
Mid February and my cold, hardened, bruised heart is warmed by the thought of a July 1st, warm summer day,
noon start of another four hour, budget (65#), three man build/race here on the sunny southwest coast of Canada.
Odd that I should be posting here on a UK site but my anscestry is British and there simply doesn't seem an
appropriate forum here in Canada to post on...
I have finalized this years design and now just need the sponsorship money and crew to start the ball
rolling and get a prototype on the water to learn from (oh, and some warmer weather).
This years motto is, simplicity.
I am, once again, very excited about the whole process of the project.
Gone are the multiple 24' 3/4" X 3/4" stringers, replaced by four 20' 2 X 4's.
Gone is the 6mil plastic skin, replaced by a 1500' roll of 16" wide shrink wrap.
Gone is the roll of tape, replaced by... the self sealing shrink wrap.
Gone is the string replaced by a few more screws.
Gone are the pontoons, replaced by triangular, 6 degree angle of attack hydrofoil/stabilizers.
Gone are the two 8' cross bars, now one 10 footer.
Gone is the feather weight of last years 65 pound boat, now 130 pounds.
Beam 1' (well, 12' if you include the cross bar and stabies)
Cross section rectangular stem to stern
Sit on top style, like last year
Bulkheads 2 compared to 12 last year
Crew this year is anticipated to be two adults and one youth.
The chubby buttocks will support the two adults aft while the fine bow the youth.
It should be 1/4 the building effort in this the 25 year anniversary of the power tool free event.
The two 120 degree course changes (corners) will prove the learned challenge with this years design
but an innovative, fixed angle, snap down intermittent rudder along with an unorthidox route plan could
prove to be the clincher in securing the gold medal!
