A design for an attractive auxiliary sloop arranged for simple construction and the generous use of plywood.
Although the plans for Hilaria show her as being planked with waterproof plywood, there is no reason why this little auxiliary could not be built using regular planking. Since the plywood planking is made up of two layers of 3/8 inch material it would mean that the ordinary planking should be about 11/4 to 11/2 inches thick. Plywood is supposedly about 40 percent stronger than ordinary wood for an equal thickness, hence the difference. The boat itself is a typical vee-bottom having fairly steep sections forward and is 24 feet 3/4 inch over all with a beam of 8 feet 81/2 inches. If ordinary planking is used, the beam would be increased a little. Draft is 3 feet 31/2 inches and total sail area is 225 square feet, with 64 square feet in the jib, and 191 in the main. A larger overlapping jib could be used and it would be quite possible to arrange a spinnaker from just below the jumper strut . The arrangement plan shows a short after deck with a locker under it, then a nice cockpit with seats down each side. The tanks as shown, one to starboard and the other to port, will hold about 15 gallons each. Both will fill from the side decks. A flush hatch in the after end of the cockpit will give access to the lazarette.
