Towiing
I have an R-27 Ranger Tug Classic (diesel inboard). One of my prime requirements was the ability to tow. Another requirement was the ability to stay-a-board for extended trips (without having to convert the bow berth to seating, or the dinette table into a berth, twice daily). I think this boat works well for a couple, as I intended. It'll never be a live-a-board. If two couples are on an extended trip - they better be really good friends.
If you are interested in towing a Ranger tug, read on, if not, then skip the rest of this post:
The R-21 variants all have a 6'8" beam. I consider this an overnighter (weekend, week long) vacation boat. Towable anywhere trailers are allowed.
The R-23, R-25, R-27/C-24, C-26, C-28 all have an 8'6" wide beams. They are legal to tow in all states on federal interstate freeways without a permit. Most (but not all) states allow towing on all roads. A few states still restrict towing to 5 miles off the freeway only to get to gas, food, lodging, etc. (old school). Some local restrictions may apply, like no two-lane roads less then 12' wide, or low bridge roads, or congested toll ways, etc. - essentially anywhere a Class A motorhome is allowed.
R-29, R-31/C-30 models all have a 10' wide beam. A wide load permit is required to tow in (virtually) every state. Restrictions vary by state: Wide load banners, flags, lights, no traveling at night or no holiday weekend towing, road restrictions, etc., etc. (In contrast, buy an annual permit in Florida for ~$15.00 and they almost don't care less what you do.) There are companies that specialize in getting all the permits for you to tow to your cross-country destination - for a fee. If you tow infrequently, to and from your favorite boating location each year (for example, down the east coast to Florida and back) - not that big of a deal. If you plan on towing all over the country, check the laws in every state you might tow through to help you decide if its worth the hassle to you.
The R-41 model has a 14' beam (included for the sake of discussion only). I don't consider this a "towable" boat, but a boat that could be delivered to the owner's destination. It would require a commercial hauler, permits, flags, flashing lights, and private or law enforcement escort vehicles, road closures, etc., etc. By the time you get to this size, I think Ranger loses it's niche advantage and your choices of manufacturer are wide open.
OK that's the Ranger/Cutwater line up (that I can remember). Happy hunting.
