Each daggerboard has a whole drilled through it at a point that will be just above the deck when the board is in the raised position. A line is run between the two daggerboards and dead ended on the outside of the board with a figure 8. The trunks have grooves that allow the knot and line to go down into the hull when the board is in the down position. To raise, you just yank on the line for the high side and it pulls the board up.
