Abstract

A fishing vessel especially suitable for fishing in icebound waters, said fishing vessel having a bow bulb, said bow bulb being rhomboid in crosssection, the edge of the said bulb being provided with an ice-ramming edge, said fishing vessel having, in the stern section of the hull, a longitudinal vertical cut-out, a fixed or an adjustable slipway being accommodated in the said cut-out, said adjustable slipway being hinged along the head edge of the said cut-out, an equipment being installed at both sides of the said cut-out, in the midship and the stern section of the hull, said equipment designed for holding of trawl ropes and of fishing gear in the water channel which is free of ice, and for holding of the trawl ropes themselves above the working deck or above the water line, said fishing vessel being equipped with a propeller situated in the stern section of an even hull. There are one, or two, recesses provided in the bottom of the hull, said recess or recesses going deeper in the direction from the midship section toward the place where the propeller is situated, so as to effectively direct the water stream to the cut-out.

Description

l

The invention relates to the shipbuilding Nij and relates to the design of fishing vessels for fishing in ice.

An ice fishing vessel is known, containing a hull with a bow and a longitudinal stern notch whose length exceeds its width, in the nose of which there is a slip and propeller, and along the sides of the longitudinal notch there is a device for keeping trawl cables and tools free from ice the longitudinal notch is partially blocked by the 1J.

However, fishing in the ice with the help of such a vessel is ineffective due to the exposure of the propeller to the unloading effect of broken ice, the invariance of the inclination of the fixed slip and the insufficient ice-breaking properties of the ship’s bow,

The purpose of the invention is to increase the efficiency of ice fishing,

The goal is achieved in that in the ice fishing vessel the propeller is located in the diametral plane of the hull under the slip, which is pivotally fixed to the hull in the bow of the longitudinal notch, and 8 the bottom of the hull on the sides of the longitudinal notch has two tunnels for supplying water to the the propeller, which is profiled with increasing cross-section towards the stern, the bow end of the hull being diamond-shaped in cross-section and provided with a cutting edge in its diametral oh plane.

FIG. 1 shows a stern eye of the proposed vessel, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 - the bow end of the vessel, side view; in fig. View B in FIG. 3; in fig. 5 building

vessel, top view; in fig. 6 - the same, side view; in fig. 7 - semi-projected hull of the theoretical drawing of the vessel in width from the propeller to 5 of one of the sides of the hull.

The vessel has a hull 1 with a bow end 2 and a stern longitudinal notch 3. The length of the notch 3 is greater than its width. In the bow of the neckline 3

10 are located a slip k and a propeller 5. Along the sides of the notch 3 is a device 6 for holding trawl cables and tools (not shown) for fishing in ice-free water. Cutout 3

15 is partially overlapped by surface closure 7 for ease of catching and increasing rigidity of body 1. The screw 5 is located in the diametral plane of the hull of the vessel under the slip. The slip is fixed 20 hinged at the base 8 of the notch 3 across the latter. At the bottom of the case 1 along the sides of the notch 3 there are two tunnels 9 for supplying water to the screw 5, profiled in side of the stern.

The extremity 2 can be made diamond-shaped in cross section and provided with a cutting edge 10 in the diameter of the plane of the hull 1 of the vessel. When operating in ice, tip 2 splits the ice cover and diverts broken ice away from the stern end of the vessel. Slip "changes position relative to the horizontal plane, which increases the convenience of fishing, carried out with the help of device 6. Tunnels 9 contribute to increased screw performance

40 5 under ice conditions.

The technical and economic effect of the implementation of this invention is that fishing is facilitated under the conditions of the presence of broken ice in water and improves the working conditions of the propeller in water with broken ice. f
