Our winch spools are very strong and will handle high line pressure. However, a line with a high stretch factor can damage a spool. We recommend to always use a low stretch line such as our Alvey Deck Winch Line. This is made specifically to have a very low stretch factor. Low stretch line does have low knot strength so we recommend using crimps for attaching your rig which can be out of any line. Deck winch line comes in bulk spools approx. 1.5kg. Sizes available are 60lb, 80lb, 100lb, 150lb, 200lb. Capacities of reels are shown in main charts.
