No, this boat doesn't have them. Surprises me too. CLC makes a similar boar called the southwester dory that has a lot of flotation built in. I think for this boat they are relying on how stable this boat is supposed to be. I'd be apprehensive in heavy air to have no flotation and no way to self rescue.
The build instructions from Chesapeake Light Craft calls for flotation added under each seat. I have floatation under the stern seat in this one but didn't want the foam under the other seats because it will get too beat up. I have a photograph of an old Life Saving Service dory that had canvas tubes filled with flotation attached to the gunnels. I plan to add something similar to this boat using old firehose filled with pool noodles.
Winter Blues just to be clear, the daggerboard is the thing which the sailor pulls upward on at minute 2:56. It extends down into the water probably 2-3 feet. A daggerboard is a type of keel, of which there are an number of styles depending on the size, style, weight, and capabilities of the boat: Centerboard, daggerboard, leeboards, wing keel, etc. all of these serve the same purpose, they allow the boat to sail in directions other than down wind. A person in an inner tube holding a t shirt up in the air can sail downwind. If you want to sail in any other direction, you’ll need some kind of keel. Picture yourself sitting in a sailboat with no wind. Then the wind picks up coming at the boat from the side, or the beam as sailors call it. The sails will fill and the boat will start to move slightly forward and slightly in the direction of the wind. The water underneath the boat will be forced backwards under the hull and across the keel. The boat as it picks up speed will generally convert most of that wind energy into forward motion, with a far smaller amount moving off to the side. That force of water moving over the hull will push the boat forward rather than sideways in the direction of the wind. It basically causes lift the same way an airplane does, except one wing is the sail and one wing is the hull and keel.
