Can I convert my boat to a Cutter Rig?


Question: I am in the process of refitting a 1975 Chris Craft Caribbean 35, which is a later version of Mark's Chris Craft Sail Yacht. Among the projects I am considering converting it from a sloop to a cutter rig. I would be interested to know if Mark has considered doing this, and what his views are on such a conversion for this boat. I beleive that S&S specified a slightly taller rig for the Caribbean 35 than the Sail Yacht. I am based in the Chesapeake, but plan to cruise the ICW to Florida and the Caribbean. I would also be interested in any other deck plan modifications Mark might suggest.

Answer: I write only with the experience of our boat in its present state and we were happy with its performance overall. All of the previous owners of my boat have kept it pretty traditional. As far as converting yours to a cutter rig, it’s within the realm of possibility, but how well it sails will likely only be known with certainty after the conversion is done. My sense is that the boat was designed that way for a reason--the advantages of cutter rigs were known at that point, too. Going to windward, I think a roller reefed working jib reefed down would be just as effective without the extra work. And off the wind the sail area is pretty small and can’t see a big boost in performance. When the wind piped up, we found that a double reef and a small working jib worked for our cruise through the Eastern Caribbean and back up to the West Coast. There are other factors to consider as well. Dinghy storage is one--we kept our hard nesting dinghy on deck, which wouldn’t have been possible with a cutter rig. And tacking a genoa around an extra stay on deck can be something of chore. It’s a project that sounds simple from the onset, but one which could become expensive and time consuming: modifying the rig, there’s also the added cost of the hardware involved, beefing up the deck, roller furling if you go that route, another set of winches, and so on. Not that it can’t be done, only how effective it will be is sort of a mystery.

Good luck with the refit. Take lots of pictures if you decide to go forward with it, and let us know how it turns out. I’d also recommend getting some opinions from knowledgeable hands on our e-mail discussion lists. I’m on the Chris Craft list and it be great to have a few more sailors on it as well.

I was sailing my Catalina 310 along the Gulf coast of Florida last spring on a light day. I had recently purchased a new-used storm jib and by God I was going to use it! I rigged a bridle from the bow cleats that are 18 inches or so aft of the forestay and hoisted my wire luffed storm jib behind my 135 genny. The sheeting angle was a bit off, but I was close reaching and able to test the configuration in 12 knots apparent wind. I set the autohelm to wind vane mode at 70-75 degrees. I set the "staysail" and checked speed, heading and windspeed. I left the main and genny alone, and doused the staysail. I found a 0.7-0.8 knot improvement with the second head sail with no loss of helm control. I wanted to test the storm sail on this bridle set up for heavy weather use, but I may have found a good coastal or off shore upwind set up. Amazing what one can acomplish with eight or nine hours of nothing but wind and water to amuse one's self!

If your roller furling headsail doesn't reef well it might be worth while to install an inner stay that attaches just below the forestay on the mast and just aft the forestay on deck. It would have a quick attach/detach fitting on deck and would be detached when using the roller sail. When the wind pipes up and the roller furling starts to lose its shape then roll up the headsail and deploy the inner stay and hank on the spitfire or other stay sail. This isn't a cutter but it solves a problem that roller furled sails present.

Having owned two cutters (an Eastward Ho and a Bayfield) as well as two sloops (a Columbia and my current Bristol) I can attest that the entire design of the boats are different. On the cutters, the mast is further aft (generally comes down in the middle of the cabin, through a hole in the table), the ballast is further aft and the head sail is generally out on a bow aprit with the stay sail being located about where the head sail is on a sloop. If you add a second head sail to a sloop you will not have a cutter, you will have a double head sail sloop. The extra work of sailing a cutter is not worth the small advantage of being able to move the center of force closer to the ballast - unless you are a dedicated offshore sailer. A sloop with a quality roller furler and double reef points on the main is less costly and more convenient to sail. I have sailed both the Eastward Ho cutter (in Buzzards Bay) and the Bristol sloop (Gulf of Mexico, on the way from Galveston and Vera Cruz) through a full gale and I cannot say that one was significantly better handling in weather than the other.

I'm not knowledgeable enough to be dangerous as yet, but having a boat with an inner, removeable, staysail rig, this topic has interested me in the past.

It seems that to be a cutter, the mast placement has to be further aft than in a sloop or ketch rig. Anything else is just a (sloop, cutter, schooner) rig with (one or more) inner forestay which carries a sail.

There's a formula, discussed in a not-too-long ago article in one of the print mags, which defines where the mast must be in order to qualify a dual-headstay boat as a cutter. I've not taken out the tape measure, but I think ours (Morgan 461) probably qualifies - but I wonder, if it wasn't designed and rigged that way, if one can call it a cutter, despite the measurements being in line?
