The correct answer is B) commence tow at a slow bell and increase speed incrementally. This is the correct approach because starting a tow at slow speed and gradually increasing the speed helps overcome the effects of static forces between the two vessels. Sudden application of high tension on the towline can cause the line to part, especially when the vessels have vastly different tonnages. By starting slow and increasing speed gradually, the tension on the towline is built up gradually, allowing the vessels to adjust to the towing forces and preventing the line from parting. The other options are not correct. Option A is not necessary, as a bridle is typically used for stability, not to overcome static forces. Option C of altering course is not the best approach to overcome static forces. Option D of rapidly increasing speed to "jump start" the disabled vessel can create excessive tension and cause the line to part.
