Are there other ways to increase effective traveler purchase?
Three things reduce effective traveler purchase by adding friction. First, If you don’t use a car and traveler control line blocks with free-rolling ball bearing sheaves or very low-friction bushings, you will need a larger purchase than normal to overcome friction. Second, using a line diameter that’s too large for the sheave will decrease effective purchase. Third, a poor lead to the cockpit, such as one that fouls on a cam cleat, runs between two sheaves, or chafes against the traveler beam or other hardware, will add unnecessary friction. Check for these problems before buying a bigger block for a higher mechanical purchase. What size line should I use for my traveler controls? Small-diameter lines create the least friction, but you’ll usually want the largest diameter line the sheave is designed to accommodate. Large lines are easier to handle , but check the block’s Max line Ø spec to make sure you’re not adding too much friction. How do I adjust my trim angle to improve boat spe
