Frequently such operations result in an entanglement of one or more of the flukes with roots, rocks, debris,
underwater cables,
pipe lines and the like making it impossible to release the anchor by conventional methods.
In order to render an anchor releasable several methods have been employed in the past but each has undesirable features that greatly limit their effectiveness.
This extra effort generally discourages the use of this method, especially since it cannot be used in crowded conditions due to space limitations and the danger of the float being destroyed by boats in the area.
While such yieldable latches may render the anchor releasable from undesired entanglement, it is likely that undesired release of the anchor may occur when the pulling force on the anchor line exceeds the bias of the yieldable latch and the anchor is rendered unusable until it is brought back onboard.
This arrangement may result in undesired release of the anchor due to a change in the direction of wind or tide which causes the ring to slide to the crown of the anchor.
This method introduces a potential weak link in the anchor / rode connection and renders the anchor unusable until it is brought back onboard.
This becomes a distinct
disadvantage and inconvenience if, for instance, the boater doesn't want to leave the slider on the anchor rode at all times but rather only wants to use it occasionally.
An anchor rode can be many hundreds of feet long and threading from the end distant the anchor can be laborious and
time consuming.
Parting the rode or disconnecting the rode from the anchor can also be laborious and
time consuming.
If care is not taken through inattention or haste, the safety of the boat and
crew can be put at risk.
Another short coming is the need to manually remove the retriever from the rode before a retrieved anchor can be brought onboard in the usual fashion over the bow roller.
Due to the bulk and complexity of the retriever, it may not easily pass through the bow roller.
In ideal conditions, it may be nothing more than an inconvenience to have to lean over the bow of the boat and remove the retriever before bringing the anchor onboard but conditions are rarely ideal.
Any of these conditions can create a situation that puts both
crew and the boat in danger.
If there is any kind of wave action, trying to manually disengage the retriever from the anchor rode while the anchor is swinging at the bow of the boat can be very dangerous.
If the
crew is inexperienced or if the boat is being handled solo, these dangers are greatly increased.
Leaving the anchor hanging at the bow until it is safe and convenient to disengage the retriever and bring the anchor onboard is also a dangerous option.
Depending on conditions, the anchor can do serious damage to the bow of the boat.
