Interlake Class Info

Developed on Lake Erie for open water, Quantum’s Interlake sails are versatile enough to excel in open, choppy water while maintaining their edge and speed in flatter, inland lake sailing. Our powerful shapes have the ability to power through the whole range.

Interlake Mainsails

Interlake Main

Developed for open water sailing, this versatile main is the perfect multiuse sail. It’s great on open, choppy water, but it also excels in flat, inland lake sailing. Made with 180 square weave, the sail comes with RBS tapered battens, vision windows, sail numbers, and a sail bag.

Interlake Jib

This all-weather jib was developed on Lake Erie for sailing in choppy waters, but its powerful shape has the ability to excel in lighter air on inland water. Made with 180 square weave, our jib is available with a Burkhart system or furling option and can be made with roller furling battens or RBS tapered battens.

Interlake Spinnakers

Interlake Spinnaker

A class, max sized sail, our spinnaker’s round, deep, powerful shape projects higher for lighter air sailing. Built from Superkote 50, the combination radial and cross cut design makes this spinnaker the perfect complement to Quantum’s versatile class main and jib sails.
