This refers to the vast array of smaller vessels that form the filler of the flotilla. They are primarily old, junky sailboats, though rowboats, lifeboats, and dinghies are also well-represented. Generally speaking, no single boat in the sprawl exceeds twenty-five feet in length, and none are vessels designed for long hauls or lengthy habitation. The inner sprawl is densely packed, but likely safer for it; should a student fall overboard, something will always be close to hand, though the risk of getting trapped or crushed between boats is high.
