The International Canoe

This one has emerged. Should be on the Thames, certainly pre WW2.

Hi
Any one know what the b class rules were? I have also come accross a referance to a BCU C class canoe does any one have a set rules for that?
Thanks
Alistair

(just re-read your post and see you were asking about the 'C' class, not the 'B'....woops)

You asked, so here you go:

These are the 1929 Rules, there were previous Class B rules in: 1914 and 1894

B Class 1929

The "B" class sailing canoe- length overall shall not exceed 17 feet (5.181m). Beam not over 3 feet 6 inches (1.067m) excluding rubbing strake. Depth of body from top of deck to underside of body at middle line, anywhere inboard of 2 feet (610mm) from either end, shall not be less than 12 inches (305mm).

The canoe shall be sharp at each end so that the included angle at any level at bow and stern shall not exceed 90 degrees and 135 degrees respectively, and the beam at 2 feet 5.1/2 inches (750mm) from the bow shall not exceed 2 feet 7.1/2 inches (800mm) and the same distance from the stern 2 feet 11.1/2 inches (902mm). The outline of any cross section from covering board to keel must be a fair curve, no radius of which shall be less than 2 inches (51mm). There shall be two transverse bulkheads of wood on each side of mid-length, but not within 3 feet (914mm) of either end of the canoe. The planking or skin shall not be less than 1/4 inch (6.4mm), the deck not less than 3/16 inch (4.8mm) and the bulkheads not less than 3/8 inch (9.5mm) in thickness, the rubbing strake not to exceed 1 inch deep by 5/8 inch thick, all finished dimensions. There shall be a cockpit opening of the deck not less than 3 feet (914mm) in length and not less than 16 inches (406mm) in width for such length, and the deck on each side of such opening shall not be less than one quarter of the beam of the canoe. Aluminium or its alloys shall not be used in the construction of the hull.

The Centre plate shall not project more than 3 feet 3.3/8 inches (1m) below the body of the canoe and shall be easily detachable.

The canoe shall not exceed 15 feet (4.572m) rating by the following expression:-

R = 15 = K x L x S1/2

D1/3

where k is a constant 0.18 for measurements in feet, or 0.0549 for metric measurements.

L is the length of the waterline measured in still fresh water with the mast spars, sails, rudder, tiller and all fixed and running rigging aboard, here inafter called the gear, sails to be furled, plate to be housed and a dead weight of 154 lbs (70 kg) placed amidships in the positions normally occupied by the crew. This may be taken as being 9 inches (230mm) forward of the arc formed by extreme end of the tiller, such point to be marked on the keel. The canoe must have been afloat for at least seven days prior to being measured.

S is the sail area in square feet or sq metres, foretriangle only being measured in the case of foresail.

D is the actual displacement of the canoe expressed in cubic feet of fresh water. This shall be ascertained by weighing the canoe, with gear and dead weight, as when measured for L and dividing the result in lbs by 62.43.Calculations of Rating shall not be carried beyond four significant figures. For the purpose of rating: D shall not exceed (0.026L + 1.03)3 but there shall be no penalty for excess except when the weight of plate exceeds 1/3rd of the ascertained weight of canoe and gear but excluding dead-weight and centreplate, then any such surplus shall be deducted from the displacement for the formula.

On calculating the rating:-

A Bermudan sloop shall take 100 per centum R by formula

Gunter rig sloop shall take 98 per centum R by formula

Gaff rigged sloop shall take 100 per centum R by formula

Yawl sloop shall take 100 per centum R by formula

Schooner sloop shall take 100 per centum R by formula

The canoe shall carry not less than two sails

A sloop rigged canoe shall have not less than 75 per centum of S in the main- sail.

A yawl rigged canoe shall not carry her mizzen more than 10 per centum of L abaft the rudder post.

A schooner rigged canoe shall carry her masts not less than 55 per centum of L apart.

If after having been measured, any alterations be made to the canoe affecting her weight or shape, the canoe must be re-measured. New or altered sails must be measured.

Notwithstanding any restriction contained in the above Rule, except as regards sail area, any canoe recognised as being a "B" class in the season of 1928 shall not be excluded from competing in club races.

Each canoe in the sailing classes shall bear a distinctive mark and/or number on the mainsail, of such character and colour, as the committee shall from time to time determine.

In every case where Boats of different Classes are eligible to race together, such time allowances (if any) as shall from time to time be fixed by the committee, may be granted to the class on her dimensions and/or sail area.

This rule is taken from Andrew Eastwood's fantastic History of the IC.

As a matter of interest, I did some research recently in some of the other canoe classes.

It was very interesting. I couldn't really work out what rhyme or reason there was to the class lettering in an international sense. There seem to be US Classes, Royal Canoe Club classes and Swedish classes. Most are dormant but others having a current resurgence.

In the US there is:

Cruising Class
C (5m) Class
ACA Class

Details at:
http://www.paddlin.com/fivelakes/classes.html

Then of course also the:

International 10 Sq M rule
National Canoe rule (details anyone?)
16/30 rule

lot of development on the 16/30 rule recently:

http://authenticboats.wordpress.com/16- ... -canoes-2/
http://www.enter.net/~skimmer/16-30.html
http://freepages.genealogy.rootsweb.anc ... iling.html


I did have the 16/30 rules somewhere, but they don't fall to hand. Presumably you can find them from one of the above links.

Then in Sweden they seem to have:

A 'B' Rule - is this the same as ours? Don't know

and 'C', 'D' and 'E' classes

Rules for those are:

The basic max. dimensions are:
D E
l.oa 6m 6m
LwL 6m 6m
beam 1,5m 1,75m
Hull weight,min 150 Kg 135Kg
Centrebord, max 50Kg 20 Kg
Ballast 150-300Kg none

By definition a canoe must have a rounded stern and a deck, so there are also a max dimension for the cockpit lenght.
The hiking boards are allowed to stick out 40 c, out from the hull side.

These are being made at moment:

or on YouTube at:

Not sure on the Swedish 'C' rules at moment.

Then of course there is the international Open Sailing Canoe.
http://www.ocsg.org.uk

There were some rules for the OC class and I had them, but I think they threw them all out and now just have a simple rule based on sail size and 'everything else goes', but on their old site they had this:

If anybody has any other information that fills any of the holes in these rules, would love to know.

Hi Ed
I came accross this article about C class canoes, I think will be able to find out more next summer in Loch lomond

http://www.ocsg.info/content/2009/mar/page1.html

I have read up about the swedish classes, descriptions on this page

http://www.algonet.se/~desoto/

I have been thinking about other canoe rule boats, not really in a position to build another boat but some time I would like to design and build another boat that I can take out in a force 6-7 (as I can with my Phantom) and still survive. You could say "learn how to sail the IC in that wind" but its always going to be manic, or "sail the Phantom then" but I did not design her. I enjoy racing the Phantom, a bit more laid back than the canoe but as I do not sail against other phantoms then I may as well sail some thing else in a handicap fleet. It would be good to design something to an existing set of rules, the most sensible would seem to be one of the swedish rules as they still exist, but if there was a british set of rules that would suit what I am looking for then that would be intresting. The B class rules seem very complicated.....

As I recall the C class rule on the Clyde wasn't necessarilly the same as the C Class rules on the Thames, let alone Sweden... nor indeed the C Class rule in 1890 much like the one in 1920...
I wrote up some of what I found out in the new history pages on the international website, rather more is in Andrew Eastwood's work.

Yep the Clyde canoe is not based on the C class rules. The class was designed as a local (one design) racing class as opposed to the cruising and camping canoes that were then sailed locally here in Scotland. For their time they were cutting edge but were somewhat fragile, the hull being a wooden frame covered with canvas though around the cockpit they were reinforced with ply so that your bum wouldn't suddenly get that sinking feeling!
The Link that Alastair gave a couple of posts above : http://www.ocsg.info/content/2009/mar/page1.html is well worth a read on the history of the Clyde canoe. A lot of stuff there is new to me. One thing not mentioned on that page is that although the craft was designed and adopted in 1938 the class really only started after 1945, for obvious reasons.

One C class offering was somewhat different to the rest by being sheathed in plywood. From memory she was built on-board ship as the owner followed his career in the merchant navy. We still have that canoe in our loft at the club. If there was enough interest I could see if we could get it on the water or at least get it out of the loft and rigged for The Europa Cup next August.
Incidentally we still have the replica canoe yawl that Andrew E. built. That yawl can also be made available to entrants to the Europa Cup...... hint hint
Prov dates, I think, Monday 29 July – Friday 2 August 2013.

Ian McP

Are those Europa cup dates set yet? As I have the following week noted in my diary.

Dates for 2013 Europa Cup

Hi Chris, the dates are confirmed as above, ie: Monday 29 July – Friday 2 August 2013.

Everyone on the IC UK email list will (should) receive advanced notice of the event in their in-box today or tomorrow.

Peter McL. also tells me that the dates were confirmed at Plymouth and an email was due to come out from t'committee soon after. However Peter will email folks today and also put info on the forum in the Europa Cup thread.

Sorry about the confusion, but "it waasnae oor fault, honest!"

IAn

On behalf of t'committee I think the dates were going to be adjusted to avoid the German school holidays and we were waiting for this confirmation.

I have started a thread under the Europa Cup for this and will put the Advance Notification on the website.

I have booked my accomodation already at the Oak Inn - looks nice!

At this year's Europa Cup/Nationals I put up a poster with the later dates, but at the ACM warned that they might be changed because the earlier week would suit the Germans better. Further investigation has shown that it also suits the Swedes better. So the dates are now Monday 29 July to Friday 2 August.

Further advance information posted under Europa Cup line.
