FIELD OF THE INVENTION
The present disclosure relates to recreational boats and wake tow towers for installation on recreational boats.
BACKGROUND OF THE INVENTION
Many people enjoy recreational watersports and boating activities. Boats used for towing wakeboarders and water-skiers may include a wake tow tower installed on the boat to provide a rope tow connection point. Need exists for improvements of wake tow towers to expand the uses and functions of boats equipped with such wake tow towers.
BRIEF SUMMARY OF THE INVENTION
The disclosed subject matter includes a platform system (hereinafter “system” or “platform system”), and platform apparatus (hereinafter “platform” or “platform apparatus”), for a recreational boat. Embodiments may include a platform system, including a wake tow tower, configured for installation on a recreational boat. Embodiments may include a boat having an installed platform system including a wake tow tower.
A platform system as disclosed herein may provide additional space above the main deck, where people may stand, sit, or lie when aboard a recreational boat. A boat having a platform system as disclosed may have more passenger area than an identical boat lacking such a platform system. A platform system may provide an elevated tanning deck. A platform system may provide shade to areas in the passenger compartment of the boat, which may be desirable for those who would like to reduce sun exposure. A platform system may provide an elevated, stable, position from which individuals may jump or dive into the water surrounding the boat on which the platform is installed. A platform system may provide an elevated springboard for diving or jumping. A platform system may provide seating area and standing area above the main deck. A platform system may provide deployable stabilizing keel assemblies for reducing uncontrolled motion of the boat, such as resisting displacement of the boat at rest on the water, and reducing rocking of the boat at rest. Such uncontrolled motion of the boat may occur, for example, when individuals use the elevated platform, jump or dive from the elevated platform, or move about the boat, or when waves and wind exert forces that tend to cause uncontrolled motion or excessive rocking of the boat. A platform system may provide stabilizing keel assemblies that may be removed from the water and placed in a stored, raised position, or stowed, when the boat is operated to run across a body of water.

Platform system 100 may include a pair of stabilizing keel assemblies 196L, 196R. Each of the stabilizing keel assemblies 196L, 196R may be supported for deployment to a lower deployed position shown in FIGS. 1-6. Each of the stabilizing keel assemblies 196L, 196R may be supported for storage in an upper stored position shown in FIGS. 7-12. Each of the stabilizing keel assemblies 196L, 196R may include at least one stabilizing fin 197 and an elongated fin-supporting member 198. Referring to FIG. 25, fin-supporting member 198 may include an upper end 202 spaced above a lower end 204. Fin-supporting member 198 may be supported at the upper end 202 thereof by being mounted in supported relationship with at least one of lower structure 120 and hull 12. Fin-supporting member 198 may be selectively moveable between a lower deployed position (shown in FIGS. 1-6, 25, 26 and 29) and a raised or upper stored position (shown in FIGS. 7-12, 27 and 28). In the particular embodiment shown in FIGS. 1-12 and 25-29, fin-supporting member 198 is selectively moveable in pivoting relationship with lower structure 120 about a pivot joint 206 between the upper stored position and lower deployed position. In the particular embodiment shown in FIGS. 1-12 and 25-29, pivot joint 206 may be a locking hinge or locking hinged joint, which may be releasably locked in the upper stored position or lower deployed position. In the lower deployed position (shown in FIGS. 1-6, 25, 26 and 29), the at least one stabilizing fin 197 is located at least partially below the waterline 208 (shown in FIG. 29) and at least partially submerged in water adjacent to the hull 12. The at least one stabilizing fin 197 may have a pair of opposed major vertical surfaces 199 oriented to engage the water to oppose uncontrolled horizontal displacement of the hull 12 across the water in the lateral direction. The at least one stabilizing fin 197 may have a pair of opposed major horizontal surfaces 201 oriented to oppose vertical displacement of the hull 12 in the water in the downward and upward directions. When each of the stabilizing keel assemblies 196L, 196R is deployed with each of the at least one stabilizing fin 197 located in the water adjacent hull 12 in the lower deployed position shown in FIGS. 1-6, proximate the opposite left side 22 and right side 26, cooperation of the stabilizing keel assemblies 196L, 196R with the at least one of the lower structure 120 and hull 12, causes the water to exert upon the major surface 199 force resisting uncontrolled movements. As used herein, “uncontrolled movements” may include, without limitation, rocking, rolling, wobbling, pivoting, sliding, turning, side-to-side, lateral displacement, vertical displacement, and horizontal displacement of the hull 12 from an initial position, orientation, attitude and location in the body of water. In an embodiment (not shown), any of the following: the stabilizing keel assemblies, at least one stabilizing fin, and the fin supporting member may be selectively may be selectively positionable in a lower deployed position as described and illustrated, or removed and stored in the vessel. In an embodiment (not shown), the at least one stabilizing fin may be selectively affixed directly to the hull in the lower deployed position, or removed and stored in the vessel. In such embodiments, for example, the stabilizing fin may be affixed with hook and loop fastener combination or other suitable fastener combination.
As best shown in FIG. 25, in an embodiment each of the stabilizing keel assemblies 196L, 196R may include a complex stabilizing fin 197 having both a first vertical major surface 199 and opposed second vertical major surface 199′, and both a first horizontal major surface 201 and opposed second horizontal major surface 201′. It will be understood that each one of such major surfaces may be disposed for engagement in opposition with the water, to oppose uncontrolled horizontal displacement of the hull 12 across the water in both the left direction and in the opposite right direction, and also to oppose uncontrolled vertical displacement of the hull 12 in the water in both the downward direction and in the opposite upward direction.
In the particular embodiment shown in FIGS. 1-6, the left and right stabilizing keel assemblies 196L, 196R in the lower deployed position may have stabilizing fins 197 located at least partially submerged below waterline 208 in direct contact and engagement with the water when the boat is floating in a body of water in an initial position or location, and occupies an initial attitude relative to the body of water, when a person is using the elevated platform. The portions of the stabilizing fins 197 that extend below the surface of the water may assist in reducing uncontrolled motion of the boat such as, for example, uncontrolled rocking from the initial attitude of the boat relative to the body of water or uncontrolled lateral displacement of the boat from the initial position or location on the body of water, that may occur when one or more persons occupies the platform 150 or when a person departs the platform 150 such as by diving of jumping off the deck surface 155 of the platform 150 or from the springboard member 192 into the body of water.
In the embodiment shown in FIGS. 1-6, left and right stabilizing keel assemblies 196L, 196R having stabilizing fins 197 may be located and supported to be deployed proximate each of the two major, opposite left and right sides 22, 26 of the hull 12. In embodiments, each stabilizing keel assembly 196L, 196R may be may be moveable to be raised, or may be removable, to be stored or stowed out of the water in a secured, raised position during operation or running of the boat 10 across the body of water under power. In embodiments, in order for the stabilizer fins to oppose and reduce lateral motion while minimally impacting the normal forward travel during running of the boat, each stabilizer fin may be shaped to present a large surface area that is aligned in parallel with the longitudinal axis and centerline C-C (best shown in FIG. 2) of the boat 12, and a small surface area that is aligned perpendicular to same. It will be understood that having the small surface area aligned perpendicular to the centerline C-C may enable running operation of the boat, for example at low speeds, in the forward or backward directions, will limit water drag on the stabilizing fin 197 and thus limit corresponding twisting forces exerted on the extension member and tower supporting the stabilizing fin 197.
In embodiments, such stabilizing fins 197 may have a multi-surface or complex cross sectional profile for also drawing the boat downward into the water during use of the platform 150 by a person, and such as during use of the platform 150 and springboard member 192 for diving or jumping into the body of water. It will be understood that the stabilizing fins 197 may be shaped and positioned to engage the water for the water to exert force against at least one portion or surfaces of the stabilizing fins 197 for the stabilizing fins 197 to resist movement relative to the water in at least one direction. It will be understood that the stabilizing fins 197 may include, for example, an enlarged head portion or enlarged foot portion to provide effective horizontal surface area engaged with the water in a horizontal plane, in addition to the stabilizing fin having an effective vertical surface area when in floating, submerged relationship with the water. In embodiments, the stabilizing fin 197 may have both effective vertical surface area portions to resist movement of the stabilizing fin 197 relative to the water in at least one horizontal direction and effective horizontal surface area portions to resist movement of the stabilizing fin 197 relative to the water in at least one vertical direction. It will be understood that, in an embodiment (not shown) a stabilizing fin 197 may be deployed below the waterline 280 directly beneath the hull 12 of the boat 10, such as directly below the centerline, and may be supported by an extension member extending under the hull 12 from the platform supporting structure 105 or hull 12. In embodiments (not show), a stabilizing fin 197 also may have at least one inflatable portion (not shown).
In embodiments (not shown), the platform system 100 may have an airfoil cross sectional shape along the front side 170 defining a forward edge, for shedding airflow around the platform system 100 from the front side 170 to the rear side 175 of the platform 150, and preventing such airflow from catching against the underside of the platform system 100 and exerting undesirable forces on the platform system 100, such as exerting an undesirable lifting force against bottom 160 of platform 150, so as to impede operation or running of the boat under power.
In an embodiment, as shown in FIGS. 1-12 and 25-29, platform system 100 may include a moveable ladder 220. Moveable ladder 220 may be installed in any of multiple locations to enable individuals to climb up and down between the platform 150 and passenger compartment 30 or hull 12. Moveable ladder 220 may be installed in any of multiple locations to enable individuals to climb up and down between the platform 150 and the body of water at the left side 22 or right side 26 of the boat 10.
In an embodiment, as shown in FIGS. 1-12 and 25-29, platform system 100 may include a safety structure 240 configured to be mounted on one of the platform support structure 105 including wake tow tower 110, and the platform 150. The safety structure 240 may have a safety rail 244 located at a safety rail vertical position spaced above the platform 150 and corresponding platform vertical position. The safety structure 240 may be configured to retain a person on the deck surface 155 in relation to the perimeter 165 of the platform 150 and to stop a person from falling off platform 150. Safety rail 244 may be oriented and proportioned to be manually grasped by a person on the deck surface 155. A shown in FIG. 27, safety rail 244 may be removable to be stowed away, or moveable to a stored position, during running operation of the boat 12 across the body of water.
In embodiments, platform system 100 may include the stabilizing keel assemblies 196L, 196R each having elongated fin-supporting member 198 that provides or defines a selected lever arm distance between the platform support structure 105, or hull 12, and stabilizing fin 197, wherein the lever arm distance is selected or determined to increase or cause desired stabilizing forces to be exerted on the platform support structure 105, or hull 12, from the elongated fin-supporting member 198 supporting the stabilizing fins 197, where such forces are exerted through the stabilizing fins 197 engaged with the body of water.
