I am potentially planning a Great Loop Trip in my Hatteras, 70', draft is 5' and bridge limit is variable, I can put mast down, but it is big hassle. How often will I need to put the mast down? How low do I need to get for safe clearance limit? Can it be done in this boat? Is there a single source document or web site that gives a good overview and potential problem areas? Thanks for the input. Best regards, J. Michael MERMAID TALES 70' Hatteras CPMY

Technically, the lowest bridge that you must be able to clear is at 19.1 feet just downriver of where the Cal Sag and the Ship and Sanitary Canal merge SW of Chicago. It is a swing-style railroad bridge that is inoperative and no longer opens. -Ryan On 3/3/2014 9:14 AM, Michael Liddle wrote: > I am potentially planning a Great Loop Trip in my Hatteras, 70', draft is > 5' and bridge limit is variable, I can put mast down, but it is big hassle. > How often will I need to put the mast down?
