Abstract
A boat shoring system for cradling and supporting a boat in dry storage comprising two or more interconnected sub-system assemblies. Each sub-system comprises a central load bearing post and two laterally spaced outside supporting stands securely interconnected with laterally adjustable and angularly directed cable or chain means tautly stretched and preferably in tension to stabilize lateral movement. Two adjacent sub-systems are further stabilized by tautly stretched center cable means. The load bearing posts and outside supporting stands are vertically adjustable and transversely movable both laterally as well as forwardly and rearwardly. The boat shoring system can be easily assembled for use or dismantled into individual components and compactly stored during non-use.
Claims21
A boat shoring system for supporting a boat out of water and in dry storage, the boat having a hull including a center keel, the boat shoring system being adapted to support the boat hull on a horizontal surface, the boat system comprising:
- at least two sub-system assemblies, each sub-system comprising a central load bearing post in combination with two biased outside supporting stands where each said supporting stand is located laterally opposite and above the central load bearing post;
- said central load bearing post having upper load bearing means for engaging the keel of the boat hull, said load bearing means secured to a vertically adjustable load bearing member operatively supported by a base plate adapted to rest on the said horizontal surface;
- each said biased outside supporting stand comprising a supporting block secured to an upwardly adjustable elongated support member skewed inwardly relative to a vertical line, said supporting block having an upper surface substantially perpendicular to said skewed elongated member and adapted to engage the boat hull, said outside support stand having a pair of outside legs and a pair of inside legs secured to an upper bracing structure adapted to operatively support said skewed elongated member between the pair of outside legs and the pair of inside legs, said pair of inside legs being shorter than the pair of outside legs and skewed inwardly less than said skewed vertical member, and said outside legs being skewed inwardly more than said skewed vertical member;
- each said biased outside support stand secured with a lateral cable means secured to the upper bracing structure of the outside support stand, and to the base plate of the central load bearing post to form a stabilizing angular cable connection between each biased outside support stand and the central load bearing post.
A boat shoring system for supporting a boat having a boat hull in dry storage, the boat shoring system comprising:
- a combination of two or more sub-system assemblies where each sub-system comprises a central load bearing post having an upper load bearing block adapted to engage the linear center of the boat hull and a pair of outside support stands where each stand is laterally spaced from the central load bearing post and includes an upper supporting block for supporting the laterally outside portion of the boat hull;
- each said central load bearing post comprising the upper load bearing block secured to a depending vertically adjustable load bearing member operatively supported by structural members secured to a base plate for resting on the ground;
- each said outside support stand comprising the upper support block secured to a biased vertically adjustable support member biased to a vertical line and operatively supported by a plurality of supporting means adapted to rest on the ground, the supporting means comprising inside supporting means and outside supporting means where the inside supporting means are shorter than the outside supporting means, said inside supporting means skewed slightly inwardly relative to the vertical line and said outside supporting means skewed considerably inwardly relative to the vertical line where the inside supporting means is skewed less than the biased adjustable support member and the outside supporting means is skewed more than the biased adjustable support member, whereby the outside support stand supports the boat hull on a bias skewed with the vertical line;
- and
- each said central load bearing post having a lateral cable means connected to the base plate thereof and further connected to the upper structural part of each outside supporting stand, and each said central load bearing post interconnected with the adjacent central load bearing post of the adjacent sub-system assembly by a central cable means.
