There are basically two hull configurations of small sailboats, each with both daysailing and performance types.
Most sailboats are monohulls, meaning that they have a single hull floating the boat.
Catamarans, boats with twin hulls, are also very popular as small beach boats. Daysailors are normally categorized as boats that are comfortable and easy to sail for a fun day on the water. Performance boats are usually faster, more complex, tippier, and less comfortable. Hull Design Small monohulls can come in a variety of sizes and shapes depending on what is expected of a boat. The main variables are weight, length, width, and hull cross section.
