New notes are dated because the details matter. Use this page for recent explanations, then follow the rubric or fieldbook resource behind each one.

25 August 2026 · Sailcloth & Materials

woven vs. laminate sailcloth

Woven polyester and laminate cloth solve different problems. Start with the load path, handling pattern and repair expectations, not a material slogan.

Dacron sailcloth weight

A cloth weight is one useful clue, not a durability score. Read it alongside boat size, cut, loads, handling and the sail's exposure to sun.

23 August 2026 · Sails & Design

mainsail vs. genoa

The mainsail and genoa work as a pair, yet each changes balance, handling and reefing in a different way.

22 August 2026 · Sails & Design

crosscut vs. radial sails

Panel direction is a load-path decision. Crosscut and radial layouts distribute cloth, seams and reinforcement differently.

21 August 2026 · Rigging & Trim

mast tuning basics

A mast tune is a sequence of observations under load, not a single tension number copied from another boat.

mainsail trim controls

how to inspect sails
