Abstract
A boat alignment device including a clamp for attachment, to a support and a block pivotally attached to the clamp. The block is provided with an aperture of elliptical cross section. A telescoping arm has an outer tubular member of elliptical cross section snugly, yet slidably positioned within the aperture in the block. The telescoping arm also has an inner tubular member of elliptical cross section nested within the outer member and capable of being withdrawn therefrom.

A boat alignment device, comprising:
- a retaining bracket including:
- a clamp for attachment to a support, said clamp having a retaining arm from which a flange extends;
- and,
- a block pivotally attached to said retaining arm adjacent said flange, said block having top and back surfaces that can selectively be engaged with said flange, said block being provided with an aperture of elliptical cross section;
- a telescoping arm slidably attached to said retaining bracket, said telescoping arm including:
- an outer tubular member of elliptical cross section snugly, yet slidably positioned within said aperture;
- and,
- an inner tubular member of elliptical cross section snugly, yet slidably positioned within said outer member and capable of being withdrawn therefrom;
- whereby said elliptical cross section provided to said outer tubular member permits such to be rotated into a tight, binding engagement with said pivot block permitting the length of said outer tubular member projecting from said aperture to be selectively fixed;
- and,
- whereby said elliptical cross section provided to said inner tubular member permits such to be rotated into a tight, binding engagement with said outer tubular member permitting the length of said telescoping arm to be fixed.

- a clamp for attachment to a support, said clamp having a retaining arm from which a flange extends;
- and,
- a block pivotally attached to said retaining arm adjacent said flange, said block having top and back surfaces that can selectively be engaged with said flange, said block being provided with an aperture of elliptical cross section;
- a telescoping arm slidably attached to said retaining bracket, said telescoping arm including:
- an outer tubular member of elliptical cross section snugly, yet slidably positioned within said aperture, said outer tubular member having a first transverse aperture for receiving a lever for rotating said outer tubular member;
- and,
- an inner tubular member of elliptical cross section snugly, yet slidably positioned within said outer member and capable of being withdrawn therefrom, said inner tubular member having a second transverse aperture for receiving a lever for rotating said inner tubular member;
- a pair of end caps secured to the opposed ends of said telescoping arm, said end caps dimensioned to prevent their passage through said aperture in said pivot block.
