Man peels tape from Uma’s hull, revealing sharp stripe
What this video covers
After nearly a year of keel work, fairing, and barrier coating, Dan and Kika finish the bottom paint on Uma, their Pearson Triton, and confirm the hull is ready to launch — but they choose to stay on the hard to complete interior and rigging work first.▶ 0:00 The bottom job involved five coats of ablative antifoul over the full hull, with two extra coats along the waterline band and down the leading edges of the keel and rudder.▶ 22:13 They extend the antifoul paint roughly 20 centimeters above the true waterline to cover the boot stripe, preventing the stubborn growth that ablative paint handles better than standard hull paint.▶ 25:32 Before painting, they install a Lumatech Seablaze X3 ultrasonic through-hull transducer — replacing a paddle-wheel knot log prone to fouling — and four Lumatech Seablaze X3 underwater lights, two bow and two stern, externally mounted through a single half-inch wire hole each.▶ 2:03 Dan explains underwater lights as a genuine offshore safety tool: illuminating wave trains one or two sets out in confused night seas, giving crew time to tack or steer in the troughs.▶ 4:03 All hull penetrations sit forward of a watertight v-berth bulkhead, leaving zero through-hulls below the waterline aft of it.▶ 26:58 A Makita drill burns out mid-job mixing paint.▶ 16:56
