The cutter rig sailboat has two jibs, the foremost one usually a high-cut yankee set on the forestay and the other a staysail set on an inner forestay. It's a flexible, easy to handle rig, which is why I - along with a lot of other cruising sailors - am such a fan of it.
Admittedly a cutter rigged sailboat is not quite as efficient to windward as a sloop rigged version, but its other benefits outweigh this small mark against it.
Often both foresails are on furling gears, but I prefer to have a furling gear on the forestay only so that I can get rid of the hanked-on staysail and replace it with a hanked-on storm jib if I need to.
The inner forestay (or cutter stay) exerts a forward load on the mast which has to be resisted. This usually achieved by either aft-intermediate stays or running backstays.
There are two variants of the cutter rig:~
One where the yankee is set on a bowsprit and the staysail attached to the bow.
This arrangement is normally found on heavy displacement sailboats, as a way of increasing the size of the fore triangle without having to extend the height of the mast.
The other where the whole rig is contained inboard, with no bowsprit like the sailboat on the right.
Examples of these are shown below:~
This is slightly more complicated than with a sloop as you've got two headsails and an extra pair of sheets to deal with when going about. Here's how we do it on Alacazam:~
Many staysails are set on a self-tacking boom, which means that going-about is simplicity itself.
Reefing a cutter in deteriorating conditions usually goes like this:~
This will leave you with a deep reefed mainsail and a staysail set on the inner forestay, which should serve you well right up to full gale conditions. It's storm jib and trysail territory after that.
On a reach you'll find it very easy to balance your sailboat perfectly with a cutter rig, such that the windvane self-steering gear will have no difficulty in keeping her on course.
But when the wind drops and falls well aft of the beam the staysail (now blanketed by the mainsail) starts to flap and disturbs any airflow into the yankee, you're effectively sailing under mainsail alone.
With a sloop you'd probably pole the genoa out to windward in these conditions and sail wing-and-wing.
This isn't an option with the cutter rig as you'd be under-canvassed with just a yankee set on the forestay - you'll need a spinnaker, a prospect that doesn't fill some sailboat cruisers' hearts with joy.
On Alacazam we just drop both sails and hoist our colourful asymmetric spinnaker, which is a classy name for a cruising chute.
Alternatively you could turn your cutter into a slutter...
Slutter isn't a formal term - it sounds a bit derogatory - but most cruising sailors will know what's meant by it.
It's so called because it's a combination of a sloop rig and a cutter rig, the crucial difference being that a furling genoa is set on the forestay in place of the yankee, but no staysail is set (initially) on the inner forestay.
This is a sloop rig at this point, so windward ability isn't compromised at all, and the genoa can be poled out when sailing downwind.
The inner forestay is likely to prevent the genoa blowing through smoothly when you go about, so it's best to roll it in a few turns before you go through the wind.
Reefing a slutter in deteriorating conditions might go like this:~
As with the conventional cutter you've now got a deeply reefed main and staysail which will sail through all but the most depressing conditions.
So what's it for you, slutter or cutter rig sailboat? We usually set the cutter rig on Alacazam, as it's a great reaching rig for cruising through the Windward and Leeward Islands of the Caribbean.
