Hull Maintenance Technician HT2 Practice Exam 2026 – Complete Prep Guide

Water management at hull joints is the key idea. A drip edge creates a small drop-off that makes water run off the edge instead of sitting on a joint, while a weep hole gives any trapped water somewhere to escape. Together, they keep moisture away from seams, reduce intrusion, and help prevent corrosion at the joints by drying out the area and limiting the time water is in contact with fasteners and sealants. Keeping these areas clear of paint, debris, and sealant buildup is important because blockages defeat the purpose.
