Consider these 3 factors to select the roller that will provide maximum protection for your boat.
There are two types of brackets (they cost the same) FLUSH MOUNT and OFFSET.
Four foot, six foot and eight foot models are available. The length needed is determined by the area that needs to be protected. Besides the rubrail, the swim platform and the bow rail need to be taken into consideration. Allowance needs to be made for the load in the boat and weather conditions.
Three inch and six inch diameter models are available. The three inch models are recommended for boats up to 30 feet in length. The six inch models are recommended for boats over 30 feet in length or smaller boats where the conditions are especially rough.
