Abstract
Abstract An arrangement for preventing the capsizing of trimaranes, and to facilitate their righting, comprising a main hull, two stabilizing hulls pivotally connected to the main hull by a pair of arms and further including a pair of extensible elastic members to restrain the upward movement of the stabilizing hulls and a plurality of flexible, non-extensible members to restrain the downward movement of the stabilizing hulls.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
84 words
Trimaran comprising in combination a hull, a pair of floats, a pair of arms each being pivotally connected to said hull and fixedly attached to one of said floats, a pair of extensible elastic members each being connected to said hull and one of said arms and capable of elastically restraining the upward movement of its corresponding float, and a plurality of flexible and non-extensible members each connecting one of said arms to said hull and capable of restraining said arm from pivoting downwardly.
Claim 2
Dependent Claim
84 words
Trimaran comprising in combination a hull, a pair of floats, a pair of arms each being pivotally connected to said hull and fixedly attached to one of said floats, a pair of extensible elastic members each being connected to said hull and one of said arms and capable of elastically restraining the upward movement of its corresponding float, and a plurality of flexible and non-extensible members each connecting one of said arms to said hull and capable of restraining said arm from pivoting downwardly.
Claim 3
Dependent Claim
125 words
Trimaran comprising, in combination, a hull, a pair of floats, a pair of arms each having an end portion pivotally connected to said hull and a second end portion fixedly attached to one of said floats, a pair of elastic members each being attached by one end portion to the second end portion of one of said arms and having a second end portion attached to said hull and capable of elastically opposing the pivoting upwardly of its corresponding float, said members each having an extensible elastic portion and an inextensible flexible cable being connected to said extensible portion, and a plurality of flexible and non-extensible members each connecting one of said arms to said hull and capable of restraining said arm from pivoting downwardly.
Claim 4
Dependent Claim
125 words
Trimaran comprising, in combination, a hull, a pair of floats, a pair of arms each having an end portion pivotally connected to said hull and a second end portion fixedly attached to one of said floats, a pair of elastic members each being attached by one end portion to the second end portion of one of said arms and having a second end portion attached to said hull and capable of elastically opposing the pivoting upwardly of its corresponding float, said members each having an extensible elastic portion and an inextensible flexible cable being connected to said extensible portion, and a plurality of flexible and non-extensible members each connecting one of said arms to said hull and capable of restraining said arm from pivoting downwardly.
Claim 5
Dependent Claim
155 words
Trimaran comprising in combination, a hull, a pair of floats, a pair of arms each being pivotally connected to said hull and fixedly attached to one of said floats, a pair of extensible elastic members each being connected to said hull and one of said arms and capable of elastically restraining the upward movement of its corresponding float, each of said elastic member having a pair of rings, an elastic band connecting said rings, each of said rings having a bar, a pair of parallel rods being connected to one of said bars and slidably extending through the other of said bars, a second pair of rods being connected to said other of said bars and having lateral ends with said first pair of rods slideably extending through said lateral ends, one of said rings being connected to said hull and cable connecting the other of said rings to its respective one of said arms.
