Abstract
A float includes a body portion having a first side surface and a second side surface, an inner surface and an outer surface, the first and second side surfaces being generally planar and forming an acute angle therebetween, the inner and outer surfaces being non-planar, and the body portion configured such that when positioned laterally adjacent an inverted second float and vertically adjacent a third float, the first side surface of the float abuts a surface of the inverted second float, and the inner surface of the float engages an outer surface of the third float.

A float arrangement, comprising:
- a plurality of first and second floats each including a body portion having a first side surface and a second side surface, an inner surface, an outer surface, and at least one strap receiving recess which extends into the outer surface, the first and second side surfaces being generally planar and forming an acute angle therebetween, the inner surfaces being non-planar and having an inner radius between a first inner edge and a second inner edge, and the outer surfaces being non-planar and having an outer radius between a first outer edge and a second outer edge, the first side surface extending from the first inner edge to the first outer edge, the second side surface extending from the second inner edge to the second outer edge, the inner radius being smaller than the outer radius, the at least one strap receiving recess forming a recess in the first outer edge and the second outer edge, and
- the plurality of first and second floats arranged in a plurality of rows and columns, at least one row containing alternating first floats having the inner surface facing upwards and second floats having the outer surface facing upwards, such that the body portion of each of a plurality of the first floats is positioned laterally adjacent an inverted second float and vertically adjacent another first float, with the first side surface of each of the plurality of the first floats abutting a second side surface of the laterally adjacent and inverted second float, with the first outer edge of the first side surface of each of the first floats contacting the second side surface of the laterally adjacent second float at a midpoint along the second side surface between the second inner edge and the second outer edge of the second side surface such that the first outer edge is offset from the second inner edge and the second outer edge in the direction of the second side surface, with the first and second inner edges of the inner surface of multiple first floats contacting the outer surface of a vertically adjacent first float, and with at least one outer column of first floats or second floats having the respective at least one strap receiving recesses align vertically down the outer column.
