MC Scow Parts

West Coast Sailing is your source for MC Scow sailboat parts, rigging and accessories. The MC-Scow was conceived by Harry C. Melges, Sr., in 1950 and was based on the M-16 hull. In 1965, Harry and son, Buddy Melges, designed today's fiberglass MC- Scow. The MC is sailed single-handed most of the time, but a crew member can be added depending upon the skipper's weight and strength of the wind. Skippers range in age from youths to sailors in their 70s. MC Scow sailboat parts, rigging, and accessories with rigging guides, technical information, extensive selection, and fast shipping to help you get back out on the water.

Rigging Diagram

Use the diagram below to reference Harken part numbers to appropriate application on your MC Scow sailboat. Parts recommendations are offered as a guide for common applications.

mc-scow-rigging-img.gif

Ratchamatic Mainsheet

Use a Ratchamatic® as the second block (furthest aft on the boom) in your 4:1 Carbo mainsheet system. It provides holding power in heavy air, but becomes free-rolling when the wind is light. Ratchet engagement adjusts to suit muscle power.

Cam-Locks: Locking headposts let you fix blocks parallel to the boom to prevent the mainsheet from twisting.

Cascading Vang System

This powerful double-ended 16:1 system features high-strength, lightweight Carbo blocks to give you fingertip sail control from both sides of the boat.
