Summary Analysis of the Design Ratios for the Rustler 36

1. A Sail Area/Displacement Ratio of just 11.4 suggests that the Rustler 36 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.

2. A Ballast/Displacement Ratio of 45.3 means that the Rustler 36 will stand up well to her canvas in a blow, helping her to power through the waves.

3. A Displacement/Length Ratio of 385, tells us the Rustler 36 is firmly in the ultra-heavy displacement category. Load her up as much as you like and her performance will be hardly affected. Few if any sailboats are built to this displacement category these days - but they remain popular with some long-distance sailors.

4. Ted Brewer's Comfort Ratio of 36.2 suggests that crew comfort of a Rustler 36 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.

5. The Capsize Screening Formula (CSF) of 1.7 tells us that a Rustler 36 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

The boat has a spacious cockpit that can accommodate four people comfortably and has a tiller steering system that gives direct feedback from the rudder. The cockpit has two large lockers that can store sails, fenders, lines, etc. The cockpit also has a sprayhood that protects the crew from wind and spray.

Mast and Rigging
The mast of the Rustler 36 is made of anodized aluminum and is keel-stepped for strength and stability. The mast has two sets of spreaders that support the masthead sloop rig. The mast has internal halyards that run through sheaves and exit at the mast base. The mast has an optional spinnaker pole that can be stored on the mast or on the deck.

The rigging of the Rustler 36 is made of stainless steel wire and is attached to the mast and the chainplates with swaged terminals. The rigging consists of a forestay, a backstay, two upper shrouds, two lower shrouds and two intermediate shrouds. The rigging is tensioned by turnbuckles and secured by split pins.

The sails of the Rustler 36 are made of Dacron fabric and are triple stitched for durability. The sails consist of a fully battened mainsail with three reef points, a furling genoa with UV protection, a staysail with hanks, and an optional spinnaker or gennaker. The sails are controlled by winches, clutches, blocks, tracks, cars, cleats and lines.

Keel and Rudder
The keel of the Rustler 36 is a long, deep keel that gives the boat stability and directional stability in a seaway. The keel is made of cast iron and is bolted to the hull with stainless steel bolts. The keel has a ballast of 3.4 tons, which gives the boat a ballast ratio of 45%. The keel has a draft of 5 feet 6 inches, which allows the boat to access most harbors and anchorages.

The rudder of the Rustler 36 is a skeg-hung rudder that protects it from damage and provides good steering control. The rudder is made of GRP with a stainless steel stock and pintles. 

The keel and rudder of the Rustler 36 are designed to match the hull shape and performance characteristics of the boat. They provide a smooth flow of water around the boat and minimize drag and leeway. They also provide a comfortable motion in waves and reduce pitching and rolling.
