Garboard and broad strake on planking tutorial

[Jim M]

Good evening,

 

I have a quick question regarding the garboard and broad strakes in general.

In the planking tutorial we split the garboard into two planks and the broad strake into three. The remaining planks are then split into four.

 

My questions are:

 

1. When the garboard is created is it generally 50 feet? Or would the ship makers use the same length as the planks of 25 feet? Similarly with the broad strake?

2. Would the planking patten then be in play if this is the case?

3. Are planks generally joined with scarf joints?

 

would the garboard and broad strakes be double the length ok the planks when the ship is being built. It seems to be unrealistic that a 50’ guard boards are installed but more realistically a 25’ boards would be and the planking pattern would adjusted accordingly. Am I correct here?

My understanding is that the garboard was just like any other plank, it was just wider. Steel does not mention anything in particular about them. Also most planking expansions I have seen, the garboard looks much like the other planks following the usual shift.

The garboard strake may be just another plank, or possibly a little wider than the ordinary planks (but there may be several widths of planks on a hull side). But I have seen cases where the garboard strake was a plank that was wider and a bit thicker than an ordinary plank. And on the MSI model I am building the garboard strake was a very complex shape several times thicker than an ordinary plank and had a variable (non-rectangular) cross section from bow to stern.

 

So the size and shape of the garboard strake depends upon the type of ship, the period, nationality and whim of the ship designer.

The garboard plank on my current model is convex in shape along the wider frames. This gives it a really nice transition from the keel but is a bit tricky to make.
