There is a great debate in the industry about which type of dock rollers for pilings should be used on a certain vessel. Some dock owners and operators feel that it is important to have the latest equipment and have access to all of the special characters on the string, whereas others feel that older models are up to the task. This can be a subjective decision based upon your preferences but there are some important things to consider when choosing a particular model.
The first thing you should consider is whether or not you want a trimend method or not. The trimend method is used by most companies when they have a lower tiered barge system. This is a method whereby all of the knots on the string are run through the machine and this removes all the extra knots. The benefit of using this is that it removes any chance of damaging the anchor and gives the boat an immediate rest after any repairs have been made.
The next thing you need to decide upon is whether you want to use a single character array or a multi-character array. The main benefit of multi-characteriery is that you will always have a fast anchor available for whenever you need one, as well as more flexibility when it comes to the shape and size of the string. The following example removes all knots on the surface of the string. This leaves a straighter stems with more room for the trimming needed. As long as the string is the correct length it will give you the most stability.
The next thing you need to look at is whether you want to use full or half horsepower. The full horsepower rating indicates that the unit has the ability to handle a greater weight. The half horsepower rating indicates that the unit will handle a smaller weight. The size of the unit is largely determined by the length of the string that you will be using. For shorter pieces of rope the half horsepower will give you better power and control.
The following example removes a single line from a five piece dock. The second cutter does not remove all the weight but only cuts the third line. The first cutter removes the entire five feet of line.
The following example removes a single line from a five piece dock. The first cutter does not remove any weight but only cuts the fourth string. The second cutter removes the entire five feet of line from the dock. The third cutter removes just the weight from the second piece of dock material.
The final step is to determine the character values you will be working with. The character values are simply a series of characters which identify the position of each piece in the dock material. If you have only one piece of dock material and if it is fastened to the dock rail then the character value for that piece is “f”. If you have more pieces of rock material which are fastened to the dock rail and if it is not fastened to the dock rail then the character value for that piece is “s”.
The function of these commands is to allow you to identify what piece in the dock has to be moved in order to remove it from positions and to move it to position n. For example, if you only have one piece of material fastened to the dock rail, then the command given will move the piece to position n where the next character will be inserted so that it can be removed from its current position. In order for nSSet to return, the current character or characters to be inserted have to be identified. The nSSet function will be used as soon as the current sequence of characters are identified. The returns for this operation are: True if the character or characters are in the list for the current position, False if the characters are outside the list and Undefined if the character or characters are in the valid list but not yet inserted.
