Interlake 18′

Never before have comfort and performance been so successfully integrated into a one design sailboat. Not only is the Interlake an exciting and challenging boat to race, it is also the perfect boat for a leisurely sail with family or friends. Its efficiently designed cockpit allows you to daysail comfortably with 2 to 6 adults. The large, dry storage area under the front deck provides lots of storage space for racing gear or picnic supplies. The hard chine hull adds stability without adding weight, while the rocker keel allows quick turning, tacking and exceptional maneuverability in tight places.

Generous sail plan makes for a fun boat to sail in light to medium air. – MICHAEL

About Interlake Sailing Class Association

The Interlake Sailing Class has something for everyone, and has been providing the best of racing and fellowship for nearly 100 years! Our goal has always been to be a Midwest regional class and to promote high-level competition in a friendly atmosphere. Members not only value the feel and performance of the boat, as well as the competition, but also enjoy the festivities which surround the events. This philosophy has served the class well for over seventy years. “Extremely tactical” is the way multi-class champion George Fisher describes Interlake racing. “The stiff mast makes a great equalizer,” says George. This fact also allows the skipper to tune into the great feel and responsiveness of the boat and concentrate on wind and tactics . . . not tweaking the rig. Interlake racing is tight!

“Our mission is to create an environment that promotes keen and friendly competition with an emphasis on teaching and assisting the entry-level sailor. The ISCA is committed to growth through the managing of sales, distribution, and marketing of the Interlake boat.”

• Sailboat Guide

Interlake is a 18 ′ 0 ″ / 5.5 m monohull sailboat designed by Francis Sweisguth and built by Customflex starting in 1933.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The Interlake was commissioned by the Sandusky Sailing Club in 1933. Francis Sweisguth, who had already designed the STAR, was hired to develop a boat for the waters of Lake Erie and Sandusky Bay. Spinnaker area: 200 sq. ft. Still an active class in the mid west USA.

Custom Flex Interlake Boats for sale in Delphos, Ohio

Custom Flex Interlake Sailboat 18 ft with Pamco Trailer

Delphos, Ohio

Make Custom Flex

Model Interlake

Length 18.0

Posted Over 1 Month

This boat is a 1975 Custom Flex Interlake sailboat. The boat is complete as far as I can tell and includes the mast, boom, rudder, tiller, main and foresail and a Pamco trailer. I am the third owner of this boat, I have not sailed it but the previous owner was sailing the boat in 2013. The hull needs some fiberglass work done where the centerboard pocket is on the hull, and the floor has delaminated. The sails, rudder, mast and boom are in good condition. The tiller is in working condition but should be replaced.The Pamco trailer is in excellent condition and only needs tires and paint. I would probably replace the wooden guides also. The boat has a title, the trailer is registered. Local pickup only. Delivery might be arranged depending upon distance. No returns unless item not as described.
