Practical Sailor's Buyers Guide: Choosing a New Cruising Mainsail

A step-by-step look at upgrading a mainsail.

The Union Cutter 36, Melelu, is measured for a new mainsail.
The mainsail of our Chesapeake Bay test boat was intact, but, after exhausting every life-extending option available­—including patches, repairs, re-stitching, and tune ups­—it became obvious that the sail was on its last legs.
As with any big-ticket item, purchasing a new main involves a number of choices, each of which are driven by an equally diverse list of factors to consider, from the type of boat (cruiser or racer) and area sailed (inshore, coastal, or blue water) to the type of sailor you are (i.e. a performance-oriented hard charger or someone with a more laid-back approach).
To help with our mainsail replacement mission, we turned to Baxter Sailmakers Ltd., a well-respected loft located in Norfolk, Va. Owner David Baxter brought a wealth of knowledge to the project and proved to be a valuable sounding board while considering the various options available. Baxter is hardly alone in this category. Although franchise affiliates garnered the lion’s share of recommendations in our recent reader poll some of the highest encomium went to independent sailmakers like Baxter.

Sail Selection Factors

Many of the decisions we faced were easily answered based on a realistic review of our boat, future sailing plans, and a review of existing mainsail pros and cons we’d noted throughout the years. Our test boat is a 36-foot Union cutter, a full-keel, heavy-displacement cruiser reviewed in the February 2010 issue. Future sailing plans include cruising Chesapeake Bay and the East Coast, with the occasional Caribbean crossing thrown in.
Once these initial questions were answered, the actual decision-making fun began in earnest. These included decisions about sail construction (cost, cloth, weight, number of reefs, etc.) as well as possible upgrades to the flaking system, track system, reefing setup, and similar details. Here’s a step-by-step account outlining the major options and selection process for our new mainsail, along with the reasoning behind each decision. While your decisions at each step may vary, the exercise can help serve as a template for your own mainsail search.


Our old main was constructed of Dacron, and while we may have briefly fantasized about the use of some exotic fiber or laminate, in the end, polyester continued to offer the best balance of cost, longevity, and performance for our particular situation. We decided to go with a premium-grade polyester (Dimension 360AP-MTO 8.4 ounce) that was described by our sailmaker as bulletproof and virtually maintenance free.
Premium polyester is tightly woven and has a high yarn count that provides good shape retention and good performance over a wide range of wind speeds. Other benefits include durability, longevity, UV stability, softer “hand” (feel of the cloth), and lower cost.
As to cons, polyester cannot deliver the same weight savings or shape that you find in high-tech laminated or fiber-reinforced cloth; however, we decided that the materials benefits made up for any loss of performance. (You can only squeeze so many knots from a Union 36.) From a cruising perspective, we felt that laminated sails didn’t offer the best value with regards to longevity, particularly as they are still subject to delamination and mildew issues despite a number of advances in the manufacturing process.

Corners, Clews, and Eyes

A few “traditional” sailmakers feel that hand-stitched elements at the corners and clew (see photos) are the best option for cruisers, on the basis that they better spread loads and are more easily serviced or repaired at sea by the owner. Others say there is nothing wrong with high-quality pressed-in eyes, as the cloth will typically fail before the hardware tears out or fails. Our existing main used a riveted aluminum headboard and pressed eyes. As both served us well over the years with no failure, we opted to use them with our new main as well. There is a difference in quality of pressed eyes, however. We used all stainless-steel eyes supplied by the Swedish sailing hardware company Rutgerson Marin.

The original mainsail left plenty of room for improvement. The external slides (above, top), though reliable, put a lot of friction on the luff. The stack height (right) was hard to manage. The pressed eyes held up well (above, bottom), but nearly all of the stitching was pulling out.

Batten Banter

One of the first post-cloth decisions you’ll have to make is whether your new main will utilize full-length battens. There are a number of pros and cons regarding full-length battens and a wide range of opinions on their merits for cruising. Some cruising sailors choose to forego battens altogether, but if you want your mainsail to have a decent amount of roach, you’ll need some form of batten support.
On the plus side, a full-battened mainsail holds its shape longer and is easier to stow (particularly with furling devices such as lazy jacks, etc). Battens allow more roach, which enhances sail performance, and also dampen sail flogging, which increases sail life and reduces noise during hoisting, dousing, and reefing.
On the downside, full-battened sails are more complicated to build and add considerable expense to the sail. Fully battened sails are also a bit more difficult to race with, as the sail is “locked” into one shape, reducing adjustment options. It’s also more difficult to tell when a full-battened sail is out of trim. Battens can chafe the sail and the pockets that hold them, and they are prone to hanging up on standing and running rigging when the mainsail is raised, reefed, or doused. Batten pockets are a primary source of mainsail repairs. Battens put significantly higher loads on the track and cars, and they also increase the stack height of the sail luff.
Our old main had full-length battens, and in our mind, the benefits provided by a battened main outweighed the negatives. However, in light of our experience with a full-battened main, we decided to try a hybrid approach — a “2-plus-2” configuration, with two full battens at the top, and two partial battens at the bottom.
On the plus side, partial battens make the sail more adjustable with minimal loss of performance (as compared to a full-batten sail). The sail is also easier to trim when hard on the wind. Since the top two full battens are still relatively short, they don’t hinder the raising or lowering of the sail.
The two partial battens still distribute the load across the sail well, but their shorter length means there is less compression at the luff. This reduced friction on the luff track makes it easier to reef. A partially battened main is easier to remove from the mast—when the need arises—than a full-battened one. It is slightly cheaper to build, and matching the length of the partial battens with the longest full-length batten reduces the number of spare battens needed. A well-made and well-cared-for, partially battened sail can deliver 10-plus years of good service.
As to downsides, a partially battened main is not as easy to stow as a full-battened one, and while the 2-plus-2 setup dampens flogging, a full-batten main does it even better. This also means the partially battened sail will lose its shape quicker.

1. Schaeffer Battslide batten receptacles (shown with Strong Track slides) can be tensioned at the luff, allowing for closed batten pockets at the leach. 2. The new Strong Track system greatly reduced slide friction. 3. Earrings at the tack cringle take the sweat out of reefing exercises. 4. Over many years, UV rays can degrade the Strong Track, causing crazing. The owner of this track estimates its age at more than 12 years. Tides offers a small discount on replacement track out of the warranty period.

Reef points

Once we decided on our batten style, next up was the number and position of reef rows to reduce mainsail area during heavier winds. Our existing main had three reef rows, each consisting of a secondary tack and clew cringles and intermediate reef points used to secure the bunt of the sail when reefed.
The primary decision with our new sail was the number of reef points. While the existing three rows may have provided more reefing options, we rarely (if ever) used the third reef, which also complicated things by adding additional running rigging.
After discussing the pros and cons with our sailmaker, we opted for two reefs rather than three. The first reef reduces the mainsail area by 15 percent, while the second is at 29 percent. Some sailmakers might suggest an even deeper reef (say 40 percent), to allow the main to function as storm trysail.
Baxter’s opinion was that trying to make the main do everything was not the best approach in our case, particularly since reefing the main to the size of a storm trysail would result in poor sail shape and less-than-ideal performance. He suggested that two reefs in conjunction with a proper storm trysail would better serve our occasional bluewater aspirations should the weather turn heavy. (For more on trysails, see “A Tale of Two Trysails,” August 2008.)
Another upgrade we made was installation of “quick cringles” (aka “easy reefs”), which consisted of a length of webbing through each reef cringle with a stainless-steel ring sewn in on both sides. The rings make reefing quicker and easier than trying to fit the reef cringle over the reef hook, while also reducing sail chafe and distortion. Some cruisers have added Dacron straps at the luff and small blocks at the clew to help pull down the main for reefing, but we opted not to have these features.

Loose Foot or Fixed

Another change from our old sail was the decision to go with a loose-footed main. Our old main had a substantial outhaul car and was also attached to the boom along its entire length, a belt-and-suspenders approach that our sailmaker deemed unnecessary. In addition to being easier to bend on and remove, a loose-footed main offers other advantages, such as easier and more efficient sail trimming. One possible downside would be the higher loads placed on the outhaul car (if not sufficiently robust).

Taming The Main

Our old mainsail utilized a Dutchman stowage system (installed by a previous owner). We considered other flaking systems for our new main (lazy jacks, lazy jack/sail cover combos, etc.), but we’ve been pleased overall with Dutchman system and decided to use it with our new main as well.
One change we made was to go with the Dutchman’s 40-3A system, which has three control lines, instead of the previously installed two-line model. Based on conversations with the manufacturer, the 40-3A was the correct system for our sail and would provide better control and performance. By sending in the tabs from our old Dutchman, we qualified for a 30 percent trade-in discount.
For more on mainsail handling options (including the Dutchman system) check out the February 2008 issue.

Slippery Upgrades

Once the basics of our new mainsail were decided, the next step was to review possible upgrades to the system as a whole. After discussing the various options available, our sailmaker stated that the biggest “bang for the buck” upgrade we could make would be to eliminate our friction-inducing external slides by installing a Tides Marine Strong Track and Slide System. The system is a mainsail luff track and slide assembly that greatly reduces the friction normally associated with raising and lowering the mainsail. The track is a single length of low-friction, ultra-high molecular weight polyethylene plastic (UHMPE) that is machined to slide onto your existing mast track. Installation is simple, straight forward, and the results when raising and dousing our new sail are nothing short of amazing.
Another great recommendation by our sailmaker was to upgrade our batten cars to Schaefer Battslide receptacles. The Battslide units (which accept both flat and round battens) allow front-end loading and batten adjustment at the mast. Front-end loading allows you to keep the leech of the sail closed (making it impossible for a batten to slip out through the leech), while the batten-tension adjustment feature makes it easier to maintain proper sail shape.
Although Schaefer doesn’t make a slide that fits the Tides Marine Strong Track system, the Tides Marine #400 slide fit the Battslide cars perfectly and provided full articulation, which makes raising and lowering the sail easier while reducing batten compression loading.


Purchasing a new main is big deal for the average sailor, an event that most cost-conscious cruisers go through only a handful of times in their sailing life. This infrequency makes it a heady experience, one that’s equal parts anticipation and trepidation as you wade through the various options and select those that will (hopefully) produce that perfect sail. As with any major project, combining your own experience with research and the advice of a professional will go a long way toward ensuring you reach mainsail nirvana. At the heart of this experience is the relationship with the sailmaker. A good sailmaker will patiently listen to your expectations and explain the various options, and more importantly, will stand by you after the sale. For those just starting their search, a list of reader-recommended sailmakers that appears online with this article is a good place to start."

"Sail" Video

So not too long ago I saw a video that had the song "Sail" by Awolnation as the background to some pretty sweet racing footage.

I've been searching for several days but can't seem to find that video anywhere. If anyone could find it, that would be awesome and they should definitely leave a comment about where to find it.

Anyway, here is the official video for the song which isn't nearly as good but what can you do?

Hace Calor!

So can we all agree that this weekend was ridiculously hot?

Yes? Ok good.

As counter-intuitive as it sounds, I spent most of my weekend outside. 

Saturday, I hung-out poolside like a dehydrated lounge lizard. The coldest the pool got was lukewarm, which was why, after about 30 mins, I opted to stay in the shade and pray for the occasional breeze.

Sunday was more interesting with a racing practice on Mazel Tov, the J/120 I'm racing on for the Governor's Cup. It was my first time with an asymmetrical spinnaker and let me tell you; boats with a bowsprit are soooooooooo much easier to gybe than symmetrical spinnakers with the pole. Hauling up and dousing are about the same but the gybe is relatively nice and easy which is good, since with an asymmetrical spin, you can't go dead downwind, which means you end up gybing quite a bit more.

The crew, aside from myself and the other foredeck guy, are older but seem to be quite a bit of fun so far.

I came back from practice dehydrated again but fixed that after about 3 more liters of water (3 Nalgenes) 

Next weekend is the Great Bay Race and then the weekend after that is the Governor's Cup. I'll try to take some more pictures so I can share with my scurvy readership.

How You Like Me Now?

Haven't been out sailing in far too long. Work and life have been getting the best of me lately. Hopefully I have some races coming up though including The Great Bay Race, Gov Cup (down to St. Mary's), Battle of the Chesapeake, Annapolis Race Week and, of course Wednesday nights.

Throw in a business trip to New Orleans and the start of law school and you have something close to my busy schedule. Maybe I'll be able to fit in reading a booking this weekend?
