Here is a comparison table:
Measurements may vary slightly especially around grip diam as it depends on grip thickness.
Brands usually state tube diam.
Carbon Wave Booms: AL360 slim vs Streamlined:
AL360 vs Mauisails:
Mauisails vs Streamlined:
Carbon Slalom Booms:
Traditional/classic boom shapes (Mauisails) with a front curvature closer to the luff, usually comfortable for those that favor an underhand grip on their forward side. Modern C-Shape booms (AL360 and Streamlined) allow the wrist to remain straight, less fatigue in the forearm/wrist especially with a overhand grip. The slightly wider shape up front will deliver more power/control with a more upright rig farther away from the body.
