Attaching Nina's yards to masts??
Posted by LAV driver on Thursday, February 26, 2009 9:09 AM

I am building the Heller Nina and I have run into difficulty understanding the operation of the rigging of these lateen sails. The model instructions show blocks and shrouds which appear to be the only thing holding up the two masts. Did these masts not require stays? Perhaps not since the masts were not so tall. I am also wondering how the yards were hoisted and attached to the masts. From the box art, it appears that they were lashed around the mast at the top but they must have been hoisted up and brought down with some kind of lift. The instructions show that on the main mast there is a line with heavy blocks attached to the fife rail abaft the mast, running through a hole in the cap at the top of the mast and then disappearing into space! (the ends cut off on the diagram as if I am supposed to know where the line ends) I am wondering if this is supposed to represent the halyard. I am not sure whether this served the yard or if it is a stay. On the rear mast the same line is attached to the bottom of the mast. There are two very large blocks on both of these arrangements. To make matters worse, there is a second line with a block that is secured to the fife rail and runs up to the base of the flag pole next to the crow's nest on the main mast. I have no idea how this served, unless it was for the pennant, but then it would seem necessary to run it to the TOP of the flag pole. Could this be how my sailor climed into the crow's nest?! 

I know a lateen is supposed to pivot somewhat and I imagined the halyard threaded through the hole at the cap on top of the mast, hauled to lift the yard and then perhaps a sailor would lash this to the mast at the correct height. Am I correct in this? I would like my model to make sense to me and I would appreciate any advice. Thank heavens the bracing makes sense in the instructions.

This sort of thing can get kind of complicated - especially if it has to be described verbally.  Pictures would help a great deal.

To begin with, just forget about what's shown in the Heller rigging diagrams.  They're notorious; the people who drew them simply didn't understand rigging.  (They got better as time went on - the "Columbus ships" were among the firm's first sailing ships - but even the diagrams in Heller's last sailing ship kit, the Victory, are full of errors.

Yeah, a lateen-rigged mast normally requires a stay.  It would run from a point near the top of the mast (probably above the yard - see below) to some convenient belaying point on the deck forward.  There do, however, appear to have been exceptions.  I just glanced through Cogs, Caravels, and Galleons, the relevant volume of the Conway's History of the Ship series; it contains quite a few contemporary pictures of ships from this period, and modern replicas of them, that don't have stays.  Sometimes there's a stay on the main mast, but none on any of the others.  I guess the shorter ones were thought to be sturdy enough without stays.

There does need to be a halyard to raise the yard to the masthead - and keep it there.  It looks like the halyard sometimes ran over a sheave in a big block built into the masthead.   

A basic feature of the lateen rig is that every time the ship comes about, the sail has to be furled, the yard has to be "topped up" (swung to a near-vertical position), and the yard and sail have to be swung around to the other side of the mast.  There are various ways to do that; the following is a guess about how such a sail would be rigged in 1492.  (Bear in mind that the extant information about such details is pretty scanty.) 

The yard is secured to the mast by a parrel - a simple fitting that sort of resembles a roller bearing.  On a small mast/yard assembly the parrel might consist of a single piece of rope running through a series of hardwood rollers (easily represented by glass beads on a model).  In the case of a larger rig, there would be two or three rows of rollers, separated from each other by a set of "parrel ribs" - wood boards with holes drilled in them.

Caveat:  the earliest example of a surviving parrel that I've run across came from the wreck of the Mary Rose (1545).  I'm not sure this method was in use 50 years earlier, but it seems reasonable.

Anyway, the parrel has to have some sort of tackle hooked up to it that allows it to be slacked off, so the yard can move a couple of feet away from the mast.  The yard has a tackle called a "topping lift," which runs from the upper end of the yard to either the masthead or, sometimes, to a point well up the next mast forward.

When the ship comes about, the sail is furled (using lines called "brails," which run from the foot of the sail to blocks on the yard, and then to the deck).  One man (or maybe two or three) hauls on the topping lift, while another slacks off the parrel.  The yard swings up so it's vertical (or nearly so), and two or three guys grab the lower end of it and walk it around to the other side of the mast (the lee side on the new tack).  The parrel tackle is then hove taut, the topping lift is slacked off, and the ship settles down on its new course.

I had an interesting conversation about this with the gentleman who's in charge of the "Jamestown Ship" replicas (the Susan Constant, Godspeed, and Discovery).  He says the crew of the Susan can accomplish that maneuver in one or two minutes.  But he also says that if the ships are heading out for a day of sailing and he anticipates that there will be a lot of tacking, he won't bother to set the mizzen sail (the only one that's lateen rigged).

For this system to work, the shrouds have to be secured to the mast above the yard (i.e., the yard has to go through its various evolutions inside the shrouds).  There are some pictures and models from the sixteenth and seventeenth centuries that depict the yard mounted outside the shrouds.  That would make the system a good bit more complex.

All that is probably a bit confusing; like I said, it would be a lot clearer in a good diagram - which Heller didn't provide.  But maybe it'll help a little.  Good luck.

Now I'm less than an amateur ship historian, but there are lot's of images of the replica on the www, including this nice if small drawing from them who built her. Might be of help:

and their site:

This is of course a rerig from a Caravelle to a Caravelle Redonda, which Columbus did IIRC in the Canaries? But I'd think the halyards and stay shown on the remaining lateen sails would be a guide..

jtilley,

Thanks for your excellent reply. I am still trying to understand these parrels. I found a picture of a model of a lateen yard here: http://www.densmodelships.com/album/How%20to%20Rig%20the%20Masts/images/2f1e472c1840d6f4a229240464ba7d5e_11447275100/:album

Is this what a parrel looks like? It does look like I could model this with beads, as you say. Did the parrel beads help the yard roll up the mast when hauled?  

One other question: What is the strange, horn-like projection on the starboard side of the bowsprit? It looks like something around which to tie a line, certainly not a decoration.

Well, I have to say I have some big reservations about that photo - mainly due to the fact that it seems to mix up features of several centuries.  (There's no way jackstay eyebolts would be found on a ship with a round top and a lateen yard.)  And I'm not at all sure exactly how lateen yard parrels were set up in Spain in 1492.  But the basic principle of the parrel is right. 

The "trucks" of the parrel have two functions:  they reduce friction as the yard swings around the mast, and as it moves up and down the mast.  A parrel on a lateen yard has to accommodate one other form of movement:  it has to be set up so it can be slacked off in a big hurry, to allow the yard to be moved a few feet away from the mast (see above).  Again, I'm not sure exactly how that was done in 1492; a bit later the parrel ropes (the ones passing through the trucks and the ribs) were seized around a round fitting with two holes in it (like a two-holed deadeye), then seized around the middle of the yard.   Then the parrel ropes would be passed through the trucks and the ribs, the whole assembly would be "wrapped" around the mast, and the ends of the parrel ropes would be passed through the holes in the "two-holed deadeye."  The bitter ends would then be secured to a block, and that block would be set up with a simple purchase to another block secured to the deck.  Casting lose that tackle would slack off the parrel; hauling the tackle taut would haul the mast back in against the mast after the ship was on the new tack.

As usual, that takes far longer to describe than it would take to rig - and a verbal description of it is far more complicated than the real thing looks.  On a small scale model you may or may not think the whole mess is worth bothering with.

I'm afraid I haven't found the object on the bowsprit.  (Incidentally - some reconstructions of the Nina in her original rig have bowsprits, and some don't.  That's one of the many subjects for debate about this whole fascinating topic.)

Hope that helps a little.  Good luck.

On a vastly smaller scale; I remember sailing Sunfishes, sailboards with lateen rigs, they had no stays and you never worried about changing the positions of the spars when tacking. The sail just lay against the mast. I can imagine that chafing of the sail would be a problem in the long haul. 

Here are two on opposite tacks:
