Wait I looked closer and it looks like they remain attached to the boom but if that is the case is some portion of them stretchy or is there a block with extra line somehow?
OK I looked again.
You have a standard lazyjack setup with permanent attachment to the boom the very top line instead of being terminated 1/3rd from the top of the mast has a block at that point so the tail end can come down the mast and terminate in a cleat reachable from deck.
Did I get that right?
The latter paragraph is correct. There is a cleat on either of the mast, just below the gooseneck. In the picture the lazy jacks have been eased and passed under the cleat, then belayed. To deploy the lazy jacks, the lines are freed from the cleat and then tensioned. There are pad eyes under the boom through the lazy jack lines pass.
As a bonus, a normal sail cover can be used. The lines do not
bang the boom or the mast.
