J chain chaser is used to recover anchors from the seabed when the anchor and the chains are detached from the buoy or the pennant has broken.
For the purpose of avoiding the damage to the chain and wire, the material of the chaser is not as hard as the material of the wire and chain.
J chain chaser is attached by a work wire to the winch of the anchor handling tug and at approximately 1/3 of the water depth.
After “snagging” the anchor chains, is towed into contact with the anchor shank and flukes enabling the tug to lift and board the anchor.
It will handle anchors to 30tonnes in weight and stud link chain up to 4-1/2inches diameter.

Ship Proportions
L/B
The ratio of the length and breadth can differ quite dramatically depending on the type of vessel. Common values:
Passenger Ships |
6-8 |
Freighters |
5-7 |
Tug Boats |
3-5 |
A larger L/B value is favorable for speed, but unfavorable for manoeuvrability.
L/D
The length/depth-ratio. The customary values for L/D varies between 10 and 15. This relation plays a role in the determination of the freeboard and the longitudinal strength.
B/T (T=Draught)
The breadth/draught -ratio, varies between 2.3-4.5. A larger breadth in relation to the draught (a larger B/T value) gives a greater initial stability.
B/D
The breadth / depth ratio, varies between 1.3 and 2. If this value becomes larger, it will have an unfavorable effect on the stability (because the deck will be flooded when the vessel has an inclination) and on the strength.
