The over all length of Lagoon is 21 feet; length on the water line, 18 feet 6 inches; breadth, 7 feet; and draft 1 foot 6 inches. The hull is of V bottom model and with construction of simple and easy-to-build characteristics. She is of transom stern type with out-door rudder, and, of course is fitted with center board.

Lagoon is rigged as a knockabout with gaff headed mainsail. It will be observed that all spars are shorter in length than the over-all 21 feet 1 inch. The principal purpose of this is to enable the spars to stow neatly on the boat if it is to be transported by trailer.

Lagoon is small; her cabin necessarily leaves much to be desired; after all one cannot expect every comfort on so small a cruiser. But there is room for two to sleep and for two to live for over night cruising. The deck house is only 6 feet long, and the headroom under its carlins is 4 feet 3 inches, however there is under the companion slide 4 feet 6 inches, and since the latter can be left open a large part of the time from the standpoint of headroom the plan is not so bad. Two berths are built in as indicated. These are 6 feet 3 inches long; the after ends being under the deck house; the forward ends abutting against the low bulkhead forward. With the arrangement as shown there is just comfortable seating room for two. With a small leaf hinged each side of the center board trunk to serve as tables here are all the comforts of home; and in addition all the charm of a small yacht's cabin.

The cockpit is sufficiently long for sleeping on the floor. Simply drop down the-two hinged seats and lay down a sleeping bag. The space beneath the bridge deck provides room for the stowage of a small outboard motor, which will be used for power, and for any other gear that is not perishable. The cockpit floor is 9 inches above the water line; therefore can be made water tight and self draining.
