Section C. Collar System
Introduction
The patented SAFE™ (Secured Around Flotation Equipped) collar system is
designed to provide flotation, fendering, and stability. The collar core is
constructed of solid, closed-cell, polyethylene foam. The coating is
exceptionally tough, scuff-resistant, UV stable polyurethane. If damage to
the collar occurs, it is easily repaired at the unit level. The collar is capable
of absorbing major impact and returning to its original shape. Damaged
sections can be easily repaired or replaced as necessary.
The water-contacting surface of the collar is protected by an aluminum
flange, which protects it from damage.

Attachment
The two side collar sections are bolted (Figure 3-23) directly to the outside
of the hull using stainless steel lag bolts. On the RB-S, the collar attachment
bolts thread into ultra high molecular weight (UHMW) plastic blocks located
at the collar attaching gussets.
The bow section on the RB-HS (Figure 3-24) is bolted through the hull and
the bow collar reinforcement bracket (BCRB) for improved impact
resistance. On the RB-S only, the collar bow section is outfitted with a
protective cover (Figure 3-25) equipped with a rub strake.
