BOAT BEACHING APRON Filed June 27, 1960 2 SheetsSheet 1 MAW Se t. 25, 1962 v. P. VALLQUIST BOAT BEACHING APRON 2 Sheets-Sheet 2 Filed June 2'7, 1960 INVENTOR. VIA/(6W7 P/l/ll/P Wilma/5r WWJ Unite The present invention relates to a marine craft accessory, and more particularly relates to a boating accessory of the type having primary utility as a beaching apron, also termable a bow and keel protector. In view of the nature of the article, such also has utility as an emergency sea anchor, as a trolling drag, as a fishing accessory, as a bumper or fender, as a protective throw cover, as a life float, and the like.

A common boating problem is presented by the risk of damage to the lower bow portion and forward keel portion of a boat when a boat is beached on a rocky or otherwise rough beach terrain, or even during passage through waters which are questionable as to depth or as to the presence of underwater obstructions. The provision of means to avoid this risk of damage to beachable marine craft is a primary object of this invention.

In terms of other and more specific objects, features and advantages thereof, the present invention provides a boat beaching apron which is light, durable, efficient, economical, readily fabricated, easy to install and use, and easily removed and stowed when not in use. The beaching apron employs means positively maintaining such in proper position against the lower bow portion and forward part of the keel of a boat until the time of contact of the bow with the beach or an underwater obstruction, and the particular elements of the beaching apron and its manner of use as characteristic of the invention also advantageously enable a boat to move somewhat on the apron after contacting the beach. Further, the apron does not impede removal of a boat from the beach. By use of the apron, the area of the boat hull most susceptible to damage and wear, ie the heel of the prow of the boat, is automatically protected at the time of beaching by not only the resilient nature of the apron but also by a light, buoyant form which can be inflatable or of a fixed form, as desired. Further, a beaching apron according to the present invention has provided in its lower portion drag means, also termable water scoop means, by which the forward motion of the boat in the water is utilized to drape the apron against the lower bow portion and forward keel portion of the boat as the boat proceeds through the water and onto a beach. In addition, it is a further advantage and feature of the boat accessory provided by the present invention that such is adaptable to other than beaching apron uses, with the water scoop means of the apron usable as a trolling drag or emergency sea anchor, with the apron and particularly the buoyant element thereof utilizable as a bumper or tender, or as an emergency life float, and with the apron also having utility as a throw cover. Yet additional utility of the apron, when utilized as a trolling drag, for example, resides in the fact that the entire apron can be of a color attractant to fish, and/ or fish attractant baits can be retained in and/ or bleed from the water scoop elements of the apron as the boat is used for trolling and the like.

These and other features, objects, advantages, and modes of utility of the present invention will be apparent from the following discussion of certain typical and therefore non-limitative forms thereof, taken in conjunction with the accompanying illustrations, wherein like numerals refer to like parts, and wherein:

FIG. 1 is a somewhat schematic view in front elevation of the bow portion of a fully water-borne boat having installed thereon a beaching apron according to the present invention, the attitude of the beaching apron as shown rates Patent ice being that occurring as the boat moves forwardly in the water;

FIG. 2 is a somewhat schematic view in side elevation of the forward portion of the boat shown in FIG. 1, showing in conjunction therewith the attitude of the beaching apron of FIG. 1 after the boat has contacted the beach bottom and is moving onto the beach;

FIG. 3 is a view in plan layout of the beaching apron shown in FIG. 1;

FIG. 4 is a view in cross section of the beaching apron shown in FIG. 3, taken substantially along lines 44 thereof;

FIG. 5 is a fragmentary plan view of a modified form of beaching apron according to the present invention, with buoyant means of fixed-form.

FIG. 6 is a fragmentary plan view of a further modified form of beaching apron, showing a typical variation in constructional arrangement of a water scoop means; and

FIG. 7 is another fragmentary plan view of the water scoop portion of a beaching apron characteristic of the invention, having associated therewith a fish attractant means.

With reference to the boat bow portion shown at FIGS. 1 and 2, it will be understood that such somewhat schematically represents and is typical of any beachable marine craft, and includes, for terms of reference, a prow 10, also termable a stern, a keel 12, and a bow edge 14, the latter also being termable the bow deck edge, or gunwale if the boat is of open construction from stem to stern. As will also be understood, that area of the bow portion where the prow 10 joins and merges with the keel 12, as indicated at 16 (FIG. 2) is termable the bottom or heel of the prow. As will also be understood, a boW edge 14 of the boat mounts several line securing means, conventional per se, such as

cleats

18, 20 and 22, for example.

Turning now to a consideration of the beaching apron shown in FIGS. l-4, the apron is suitably fabricated from flexible, comparatively heavy sheet stock, such as rubber, plastic, ruberized canvas, or the like and, as shown, is preferably of generally hexagonal shape in its main body portion 24, the general configuration providing an upper edge constituted by the two adjacent sides 26 and 28, two outboard sides 3% and 32, and two trailing

sides

34 and 36. Securing

lines

38, 40 and 42 are fastened as by lashing to the said upper edge of various spaced points along said sides 26 and 28, as by

grommets

44, 46 and 48, with the strength of the sheet being suitably reinforced around said grommets, as desired, such reinforcement as shown in the beaching apron illustrated at FIGS. l-4 being by means of an extra ply of the sheet material, as provided at St and 52 around

outboard grommets

44 and 48, and as provided for central grommet 46 by the additional ply 54 applied in forming the inflatable buoyant element of the assembly, as discussed more fully below.

In the upper central portion of the apron, said additional ply 54 is in the general configuration of an inverted, shallow V and attached around its edges to main body 24 of the apron, to provide an inflatable buoyant element, as generally indicated at 56. Attachment of

plies

50, 52 and 54- to main body 24 can be by any suitable procedure, such as cementing or vulcanizing. The inflatable space 58 (see FIG. 4) defined by the sealed edges of ply 54 is inflatable by means conventional per se such as an inflating tube or valve 60, the attitude of the inflatable element when deflated being generally shown at FIG. 4 in solid line and the attitude when inflated being generally shown in broken line at said FIG. 4, as indicated at 55.

In the lower portion of the apron, and specifically in the proximity of the lower, outboard corners of the apron, a pair of drag means, also termable water scoop means,

pockets or pouches, are provided, as generally indicated at 62 and 64'. Each such scoop means can be suitably fabricated by cementing or vulcanizing the edges of re spective

additional plies

66 and 68 of the sheet material to the main body 24 along the sides and bottom of the scoop means, as shown, leaving the upper edge open so that the scoop means exerts substantial drag in the water as the boat moves forwardly, the open nature of the scoop means being apparent from the illustration thereof at FIG. 1, and also at FIG. 4. With respect to said scoop means or pockets 62 and 6 5, it has been found desirable to provide such with bleed holes or water escapement means, near the bottom thereof, such as indicated at 7th and 72, to relieve some of the water pressure therein and to facilitate drainage. Such bleed holes or water escapement means 79 and 72 also augment the utility of the apron when fish attractants are placed in the scoop means or pockets, as discussed more fully hereinafter in connection with FIG. 7.

Typical use of the accessory illustrated in FIGS. 14 as a beaching apron proceeds as follows. Assuming the apron has been in stowage on board the boat, the apron is unfolded, the buoyant element 56 inflated, and the apron is hung forwardly of the bow with lines 33, 4d and 42 secured to

cleats

18, 20 and 22, leaving said securing lines rather slack, substantially as shown in FIG. 1, for

example. Then, as the boat proceeds forwardly toward the beach, water scoop means 62 and 64 exert sufficient drag to sweep the apron back under the bow and drape the same against the lower portion of the bow and forward portion of the keel as well as the adjacent prow and bottom areas. At this point of the operation, it is important to note that the apron is prevented from sweeping too far rearwardly, i.e. too far under the bow, by action of the buoyant member 56, in that said buoyant member supports the weight of the apron and keeps at least part of the apron above the water line (indicated at WL at FIG. 1). At this point, also, the inverse V configuration of buoyant element 56 serves the very advantageous function of being self-centering against prow 10 of the boat, maintaining the trailing portion of the apron also substantially centered. When the boat is fully waterborne and proceeding toward the beach, the position of the apron as shown in FIG. 1 can be thus established and maintained by the conjunctive action of buoyant element 56 and water scoop means 62 and 64, and not by

lines

38, 40 and 42.

As the boat proceeds toward the beach with the beaching apron in the bow and forekeel draping position shown at FIG. 1, when the heel of the prow and forekeel of the boat reach ground at the beach (the beach being indicated at B at FIG. 2), forward movement of the boat over the ground causes the prow to come out of the water and the apron to be momentarily arrested on the ground, until relatively rearward movement of the apron causes

lines

38, 40 and 42 to become taut, whereupon the bow moves farther onto the beach with the apron sliding over and taking any sharp impact from obstacles on the beach ground. With respect to this beaching action, it is important to note that the initial slackness of lines 38, 4t) and 42 has permitted movement of buoyant element 56 into a position substantially at the heel of the prow (i.e. over heel 16 as shown at FIG. 2) which is the point of greatest risk of damage and wear by beach roughness and irregularities, and which point is thereby protected not only by the resilient nature of main body 24 of the apron, but also by the inflated nature of buoyant element 56. Further, it is to be observed with respect to the relative movement of the apron as the boat hits the beach ground that the initial movement of the boat onto the beach is facilitated because the prow heel and forekeel slide initially on the wet apron surface and not on the beach ground itself.

FIG. 5 illustrates a typical modification of the buoyant element of the beaching apron, the element retaining ply 54' afiixing to main body 24 of the apron a fixed-form float 74, such modified buoyant element being generally indicated at 56'. Said float 74 can be of any suitable type, such as Styrofoam or cork block of preferably oval lateral cross section, for example.

FIG. 6 presents a fragmentary view of a typical modification of one of the scoop means or pockets, as generally designated 64'. In this modification, the open or unattached edge 76 of the pocket is curvilinear and the outboard edge 78 of the pocket is longer than inboard edge 34) to provide that most of the water spilling from the pocket when in drag attitude (cf. FIG. 1) leaves the pocket on its inboard side, the resultant drag force having an outward directional component to aid in maintaining the apron laterally taut under the bow. In this modification, bleed hold 72 is suitably at the lower outboard cornor, as shown at FIG. 6.

FIG. 7 illustrates a further use variation with respect to a typical scoop means characteristic of the invention, wherein a fish attractant means is retained by the scoop means. Thus, choosing scoop means 64' of FIG. 6, for example, bleed hole 72 retains a porous sack or bag 82 of leachable fish attractant such as a scented fish meal, the retention being by means of string 84 and pin 86. Obviously, the retention of the fish attractant can be either externally or internally of the scoop means, a further variation in this respect involving a loose fish attractant such as bait eggs or other fish feed simply loosely deposited in the scoop means and gradually escaping through bleed hole 72'.

To utilize the beaching apron for trolling drag purposes, as is often desirable where a relatively small boat is powered by a relatively large motor which will not idle sufiiciently slowly to give a desired trolling speed, the beaching apron is hung forwardly over the bow of the boat, as shown in FIG. 1, and the drag action of the scoop means slows the speed of the boat quite materially. As will be obvious, this utilization can occur with or Without conjunctive utilization of the scoop means for fish attractant purposes, as discussed in connection with FIG. 7. Also, as will be apparent, the color of the apron can be any color desired for fish attractant purposes, such as a fluorescent green or red.

With respect to utilization of the beaching apron simply as a bumper or fender, it will be apparent that

lines

38 and 42 provide means by which the apron can be draped at any desired location on the boat when approaching or mooring to a dock or the like and that the apron and particularly the buoyant element thereof will in such position perform the same function as a conventional bumper or fender. The buoyant element of the apron also provides, at least to some extent, an available life float in the event of emergency need for such. Likewise, the substantial area of the apron permits further utility thereof as a weather cover over any portion of the boat, such as a seat, cockpit, or motor. A brightly colored apron can also have utility as an emergency signalling device, to attract attention.

The scoop means of the apron also have a degree of utility for use as an emergency sea anchor, the drag of the apron and its scoop means being of aid in reducing drift, maintaining a desired bow direction and calming water on its lee side. For such use, the apron is of course turned over so that the scoop means still face downwardly when the boat to which the apron is secured drifts at a distance from the apron.

In view of the widely diverse nature of the various utilizations attributable to a beaching apron characteristic of the invention, and because of the various functions it performs, it will be apparent that many modifications in specific construction and design are possible. Thus, by way of further illustrative example, the upper edge of the apron can be further or otherwise reinforced, and a wide variety of buoyant elements and considerable latitude as to their exact size, shape and placement are possible. Also, considerable latitude is possible with respect to the placement and configuration of the scoop means, and the outline shape of the apron, consistent with the desired manner of operation and function it is to perform in a particular instance. As will also be apparent, any suitable material and fabrication technique can be employed to form the apron and its components, consistent with the desirability as to its durability, lightness in weight, resilency, and flexble nature.
