Patrol boat HY830-Alu

outboardaluminumrigid hull

Product Overview
Professional 27 ft (8.30 m) aluminum patrol boat HY830-Alu designed for maritime patrol, search and rescue (SAR), beach landing support and commercial transport. Fully welded marine-grade aluminum hull and internal skeleton with a solid closed-cell EVA foam collar spray-coated in polyurea around the gunwale for permanent buoyancy and impact resistance. The 23° deep‑V hull improves seakeeping, reduces slamming and delivers a drier ride. Rated for twin outboard configurations and up to 10 persons.

Key Features

• 100% welded marine-grade aluminum hull and internal aluminum skeleton for structural strength
• Polyurea-coated solid EVA foam collar providing permanent buoyancy and high impact protection versus inflatable tubes
• 23° deep‑V aluminum hull for efficient wave cutting and improved seakeeping
• Designed to carry up to 10 persons; supports twin outboard engines (recommended twin 225 HP)
• Integrated 450 L fuel tank for extended operational range

Polyurea-EVA Collar Benefits

• Permanently buoyant closed-cell EVA core: vessel remains afloat if outer coating is compromised
• High impact absorption for pier landings and beaching operations
• Zero maintenance compared with inflatable Hypalon/PVC collars
• Excellent resistance to UV, saltwater and abrasion; closed-cell core does not absorb water

Applications

• Maritime patrol and security
• Search and rescue (SAR)
• Beach landing and shallow-water deployment
• Coastal defense, transport and logistics

• Recommended maintenance interval for professional users: every 50 hours or 6 months, whichever occurs first
• Permanent buoyancy from closed-cell EVA core ensures flotation if outer skin is damaged
