Description
- This application claims the benefit of Provisional Application No. 62/353,458, filed Jun. 22, 2016, which is hereby expressly incorporated by reference in its entirety herein.
- Docking a boat can be one of the most stressful tasks you will perform, especially for new boaters. The boater needs to get the boat right up to the dock, but not too hard, to avoid any damage to the boat or to the dock. The approach to a dock will depend on the space available to dock, as well as wind and currents.
- Typically, the boater will deploy fenders and lines on the side of the boat that will be adjacent the dock. The boater will typically approach the dock at an angle, applying power intermittently to approach the dock at a slow, controlled speed. As the bow is nearing the dock, with the engine in neutral, the boater will turn the wheel away from the dock, then go forward at idle speed for a few seconds; then go back to neutral. The bow will turn more parallel to the dock. Momentum should then carry the boat towards the dock. A brief burst of reverse at idle speed may then be applied to stop the forward motion, and the prop wash should push the stern towards the dock. To successfully perform the docking, without damaging equipment, the boater must learn to use intermittent power to control the speed of the boat, and to turn at the proper time such that the boat ends up next to the dock If the boater turns too soon, the boat will not end up next to the dock If the boater turns too late, the bow may hit the dock before the watercraft turns.
- Many boaters will not undertake docking without having a second person on board to assist with the maneuver, for example, by leaping from the boat to the dock with a mooring line to either prevent the boat from impacting the dock, or to pull the boat towards the dock. Therefore, boaters are unable or unwilling to take the boat out by themselves, which can greatly limit the opportunities for boating.
- The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
-
FIG. 1 illustrates a docking system in accordance with a first embodiment of the present invention; -
FIG. 2 illustrates the docking system shown inFIG. 1 , as the boat is engaging the docking system; -
FIG. 3 illustrates the docking system shown inFIG. 1 , with the boat positioned at the dock; -
FIG. 4 illustrates a second embodiment of a docking system in accordance with the present invention; and -
FIG. 5 illustrates the docking system a second embodiment, with the boat positioned at the dock. - A first embodiment of a
docking system 100 in accordance with the present invention is illustrated inFIGS. 1-3 , installed near aconventional dock 90 in position to be engaged by aboat 99 that will be moored at thedock 90. In this embodiment aswing arm 102 is attached to, and extends away from, a shore ordock walkway 94 and into the body ofwater 94. Theswing arm 102 in this embodiment is configured to pivot or swing about its proximal end. Thearm 102 may be temporarily attached to the shore ordock walkway 94, for example, by lashing theswing arm 102 to thewalkway 94, e.g., at an attachment fixture, such as a post or acleat 95A. The distal end of theswing arm 102 is biased away from thedock 90 with an elastic or partiallyelastic line 104 that is secured to asecond attachment fixture 95B on the shore ordock walkway 94. For example, the elastic line may comprise a conventional nautical line attached to a bungie-type of elastic member. Optionally, one or more elongate buoys orfloats arm 102 to improve the visibility of theswing arm 102 and to maintain theswing arm 102 at or above the water surface. - A
first line 106 is secured at one end to acleat 95C on thedock 90 and extends towards a distal portion of theswing arm 102. Thefirst line 106 is secured to one or more floats orbuoys short line 108 to theswing arm 102. In one embodiment a connector ring is provided for connecting thefirst line 106,floats short line 108. In one embodiment the floats orbuoys - Another connecting assembly comprising a
second line 110 that extends from thedock cleat 95C towards theswing arm 102, that engages two or more buoys orfloats swing arm 102 through theshort line 108. The buoys orfloats second line 110 and thefloats first line 106, for reasons that will be apparent from the FIGURES. Athird line 112 extends from thewalkway cleat 95A to theshort line 108 and, may also engage the ring limiting the distance thefloats walkway 94. - The operation of the
docking system 100 will now be described, with reference toFIGS. 1-3 , which show theboat 99 engaging thesystem 100. The boat approaches thedock 90 anddocking system 100, generally as shown inFIG. 1 . InFIG. 2 , as theboat 99 begins to engage the docking system it first passes over thefirst line 106, which is thereby urged under theboat 99 pulling thefloats 1Aboat 99, on the side opposite thedock 90, causing theswing arm 102, which is biased outwardly byelastic line 104, to pivot towards thedock 90. As theboat 99 continues to move forward, thefloats boat 99 and gently urge the bow towards thedock 90. - The
second line 110 is longer than thefirst line 106, and is therefore initially relatively slack. As theboat 99 continues forward the bow of theboat 99 engages one or more of thefloats second line 110 to become taut. Thefloats boat 99 and works together with thefirst line 106 to urge theboat 99 closer to thedock 90, and to impede the forward motion of theboat 99. As thefloats boat 99, theline 110 swings inwardly toward thedock 90, aiding in correctly positioning theboat 99. The impeding force provided by thefloats boat 99 towards thedock 90. Thesystem 100 therefore permits a single user to easily dock theboat 99, as shown inFIG. 3 , without requiring assistance from a passenger or others on thedock 90. - When the
boat 99 is backed away from the dock, thethird line 112 secures the float assembly, limiting the distance the floats can move (upwardly, inFIG. 3 ). The elastically coupledline 104 urges theswing arm 102 away from thedock 90, maintaining the vacateddocking system 100 in position to receive theboat 99 on its return. - A second embodiment of a docking system 200 in accordance with the present invention is illustrated in
FIG. 4 . The docking system 200 is similar to the docking system shown inFIGS. 1-3 , with anelongate arm 202 spaced away from thedock 90 and extending into the water, afirst line 206 extending between theelongate arm 202 and the dock with thefloats boat 99 during docking, and asecond line 210 withfloats boat 99. For brevity and clarity, the aspects of the system already described above will not be repeated. It will be appreciated that in both of thedocking systems 100 and 200 thesecond line boat 99 to impede, prevent, and/or stop the forward motion of theboat 99, even when, for example, using engine power to urge the stern end of theboat 99 towards the dock. - The second embodiment differs from the
system 100 in that theelongate arm 202 is installed at a generally fixed orientation in the body of water, and thelines 206, 210 (with connected floats) extending between thedock 90 and theelongate arm 202 are biased towards the elongate arm by a weight oranchor 209 connected to a line that extends through a passageway, eyehole or pulley in theelongate member 202. The stopping buoys orfloats - In the docking system 200 shown in
FIG. 4 , the buoys orfloats second line 210 are configured to provide improved holding power over the embodiment ofFIGS. 1-3 , for example, to accommodate larger watercraft and/or to guard against an operator's use of too much engine power during docking. - The bows of different boats may have different shapes. For example, a bow may be “plumb,” sharply “raked,” or a “spoon” bow.
Different buoy configurations third buoy 2C, which provides better stopping affect, as described below. - In the docking system 200 shown in
FIG. 4 thefirst line 206 may be provided with one ormore weights 207 along its length, such that theline 206 is partially submerged prior to engaging theboat 99 to prevent the first line from snagging on the bow and facilitate its passage under the bow, to pull the floats orbuoys boat 99. - In the docking system 200 the
elongate arm 202 is secured to thewalkway 94 at its proximal end and with athird line 204 that does not elastically bias toelongate arm 202 towards an open position, but rather secures thearm 202 at a desired orientation in the water. The first andsecond lines third line 214 that slidably extends through a passageway on thearm 202, for example, through an eyehole screw or pulley. Thethird line 214 is secured to a weight, for example, amushroom anchor 209 such that the first line 206 (and buoys orfloats elongate arm 202, in position to receive theboat 99 for docking. - A particular advantage of some embodiments of the present docking system is that the
