A universal framing system for a boat dock generally includes at least one standardized dock frame. The standardized dock frame is in a rectangular shape. Each of the standardized dock frames include a standardized left side member, a standardized right side member, a standardized front end member, and a standardized back end member. The standardized left side member may be on a left side of the rectangular shape. The standardized right side member is on a right side of the rectangular shape. The standardized front end member is on a front end of the rectangular shape. The standardized back end member is on a back end of the rectangular shape. The standardized left side member, the standardized right side member, the standardized front end member, and the standardized back end member are configured to connect together to create the rectangular shape.

A boat stand to support a boat above a support surface. The boat stand includes a support column and a top pad pivotally mounted to the support column. The top pad includes a plate, a mount with a receptacle that receives a head of the support column, and at least one wing with an opening to connect a chain.

An alignment guide for a pontoon boat lift that includes a pair of laterally spaced rails, where the spacing corresponds to the spacing between the pontoon floats. The rails are attached to the boat lift by adjustable brackets, so they are positioned at an elevation above the waterline of the pontoon floats, and below the deck that is supported by the floats. A stop bar is positioned at an elevation above the boat motor and extends between rail extensions that are directed downwardly and rearwardly from the spaced rails.

A jack-up platform is described having a horizontal working deck that may be jacked up out of the water by moving its legs to a position wherein they take support on an underwater bottom. The jack-up platform further comprises a mooring system for mooring a floating vessel at a mooring side of the jack-up platform. The mooring system comprises an elongated support means for supporting a hull part of the floating vessel, and guiding means connected to the hull of the jack-up platform at the mooring side. The guiding means are able to rigidly hold the elongated support means in a support position, in which the elongated support means is within reach of the hull part of the floating vessel to be supported when the hull is jacked out of the water and the jack-up platform rests on its legs. A method for mooring a floating vessel using the jack-up platform is also described.

Disclosed herein is an alignment system which is tractable by amateur boat builders and flat-packable for shipping, to assist such builders in assembling plate-based boat hulls free from hull skin warping, such system comprised of (a) longitudinal and transverse skeleton elements, such elements employing half-lap or similar joints and (b) an alignment jig comprised of a horizontal plate with intruded deep slots corresponding to the thickness and location of upper edges of the skeleton elements. The jig is set atop a planar surface (i.e., concrete floor or worktable), with the slots facing upwards. The skeleton elements are inverted, mated with each other at the half-lap joints, and inserted into the slots in the plate jig. The slots and the skeleton joints work together to maintain precise location and rotation of all skeleton elements, such that the edges of the freestanding skeleton present a developable arc for hull skin panel installation.
