The Accepted Canoe Warning .pirates.

The casual reader of .pirates has probably seen warnings about canoe building:
  • From Bruce Schlickbernd on the Armada Flagship: “You can add another center section, but beyond that it starts to look like a canoe.”

-snip-

   Words of wisdom, and you even wisely quote the artist first, who surely has a good eye for these kind of things. :-)

Of course!

  
   Surely, the USS Constellation is not canoelike? Well...

When I was at the Lego store in Anaheim just a couple of weeks ago, I looked at the Constellation in passing and I thought it looked a bit canoe-ish (really!).

I’ve had a browse of www.constellation.org, and while I wouldn’t describe the real constellation as canoeish, she does seem long, narrow, and fairly straight sided.

  
  
Vessel

LEGO USS Constellation

50 studs
   10 studs

Real USS Constitution
   175 feet
   43.5 feet
   4.02:1

You are quoting the waterline length. The overall length is 204 feet for the Constitution - and by this, they mean “head (bow) to taffrail”. Anyway, that would make a ratio of about 4.7 to 1 as opposed to the 5.6 (the bow would include anything but the bowsprit) for the Lego Constellation.

You’ve lost me there... how would using a larger measurement for the length, make the length:beam ratio smaller?

   Visually, this is what you will key on. Going over a ratio of 5 to 1 is going to increasingly make the ship look like a canoe...or more properly like it is a later era clipper or schooner that has (or should have) more than three masts (4, 5, 6, 7, I believe there was a 9, maybe more).

Agreed.


   The Mary Rose, a much earlier ship, didn’t even rate out to 4 to 1 (looking and calculating...about 3.8:1), and about 3.25:1 at the waterline). This pretty much confirms what our tells us: the earlier ships were tubbier.

True.

Looking at the ratio’s above, if you accept the LEGO Constellation is not too canoelike, and use a 5:1 length to beam ratio, you could safely go to 6 (and maybe even 7) sections using standard wide hull pieces.

Note that these numbers make no allowance for overhangs fore or aft. Nevertheless, these are scary numbers compared to what is normally used.

I suspect you are trying to prove a bumblebee can’t fly.

Maybe :-)

  
   Maybe the canoe myth arose when ship builders where laying out the hull sections, and constructing the middle layers of the hull. Maybe it arose because traditional LEGO Black Seas Barracuda designs were used (with no deck) and the ‘see through to the keel’ effect reminded people of canoes. I know I got nervous when I laid out the six centres for the Misérable and saw how long it looked ... and seriously considered revising the design to five.

I always judged by looking at someone’s finished ship.

The Misérable did not attract any ‘canoeish’ comment when I first posted it. I still don’t think it does look canoeish.... this pic probably shows the length and breadth the best. I don’t think it looks too long (or two narrow), although I do increasingly think it might be a tad to tall.

  
   A dimension I haven’t explored here is the vertical, either the hull or the rigging. Looking at the Misérable now, it looks a bit too tall in the hull for it’s length, and maybe now I now the ratios, I’ll be brave and take the next Misérable out to eight centre sections. ;-)

I do remain convinced though that the biggest obstacle to ship building is the rigging. Masts aren’t too much of a problem, but keeping them stable is. The existing long ratlines aren’t tall enough for the Misérable, so they’re not going to be tall enough for anything bigger. I think the solution may be either joining ratlines or coming up with strong enough tops which can be used on mast pieces in lieu of the 6x6 with clips top plate.

You literally need to use the same rigging as a real ship to some degree and stabilize the masts not just to the sides: fore and aft “stays” help (string, or the one-round-plates connected by string).

Yes! Once you get very tall, you’re putting a lot of leverage on whatevers anchoring the ratlines.

  
   I think the key to building bigger vessels is to experiment a bit instead of following the accepted wisdom. A bare six section hull may look a bit canoelike, but once the hull is properly completed (and a deck added!) it’s likely to look properly ship shape!

So, let’s see some bigger ships!


You do the work, I’ll tote along the canoe paddles! :-)
