OSRS Bolt of Canvas Guide (Sailing)
© gamerblurb.com | Published on 11/21/2025 at 4:20 PM CST (USA)
Canvas is one of the core parts for building sails in Sailing, so knowing how to make bolts fast helps you upgrade masts and push into new seas.
How to Get a Bolt of Canvas
A bolt of canvas comes from a loom. You need level 39 Crafting and two hemp yarn. Each bolt gives seventy five Crafting experience. You can make them as soon as you grow hemp, spin it, and bring the yarn to any loom.
How Bolt Crafting Works
You plant hemp seeds in a hops patch. They take about 80 minutes to grow. When they finish, harvest them and spin the hemp into yarn. Two yarn turn into one bolt of canvas at a loom. The animation is quick and the make all option cycles smoothly. You can stack yarn and mass craft bolts for large mast upgrades later.
The Grand Exchange price can spike when new sail parts release. Some players farm seeds from salvaging ship remains, grow them, spin them, and turn them into bolts for profit. Prices shift fast, so move early if you want to sell.
What Bolts of Canvas Are Used For
Teak Mast and Canvas Sails
Sailing level needed 36
Construction level needed 26
Materials teak logs, steel nails, canvas
Canvas needed 5 or 10 depending on tier
Mahogany Mast and Canvas Sails
Sailing level needed 52
Construction level needed 45
Materials mahogany logs, mithril nails, canvas
Canvas needed 5 or 10 depending on tier
Camphor Mast and Canvas Sails

Canvas needed five or 10 depending on tier
Each mast has three versions. Higher tiers need more logs and nails but the same canvas amounts. Canvas turns into the actual sail when you build the part on the blueprints board.
How to Farm Hemp Seeds Fast
Hemp seeds drop from salvaging shipwrecks. Large wrecks give more rolls and can stack seeds fast if you stay on a good spawn loop. Salvaging crew also helps by pulling extra salvage into your cargo hold. Once you have a few seeds, start a hops patch cycle and keep it rolling. With steady planting, you always have yarn ready for canvas.
Final Blurb
Bolts of canvas stay useful from your first raft upgrades all the way to high level masts. Grow hemp, spin yarn, weave canvas, and keep stacks ready for future ship builds. The smoother your canvas flow, the faster your boat grows.
