RedactedNarrative: V1 passed under the Boca Raton Inlet bridge south bound heading to the Atlantic Ocean, while recreationally cruising. 
  
  On the south side of the inlet bridge, the City of Boca Raton dredge (V2) was in full dredge operation mode and pumping. V2 does not have propulsion, it is maneuvered using submerged cable system and is "Restricted in Ability to Maneuver (RAM) USCG Rule 27-b-2. With this designation it is required by regulations that V2 have day shapes of ball-diamond-ball prominently displayed at a clearly visible point, the day shapes were in place and easily visible. 
  
  OP1 stated he saw the dredge and started heading slowly (the tide was going from high to low causing an outward current). This also added to V1's headway speed pushing 1/1. OP1 stated he saw the dredge personnel waving him on. I asked if he contacted the dredge by VHF 16, due to it's RAM condition for clear direction and an understanding between both vessels. He stated he did not because people were waving to him. 
  
  I asked OP2 if V1 used sounds signals per Rule 34 (a) Maneuvering and Warning Signals, to indicate his intentions since no VHF Channel 16 contact was made between vessels. He stated V1 did not. OP2 and crew members all stated they were not waving to Vi to pass as stated by V1's people, rather the two crew members of V2, both standing on the port and starboard bow of V2, said they were waving V1 off due to the dangerous position that OP1 had put V1. 
  
  OP2 stated that Vi was attempting to pass on V2's west side initially. Once V1's operator realized it was impassible due to large floating pipe obstructions. V1's course correction from a south-westerly direction to south-east was too late. OP2 noted that V1's vessel width was too wide in order to pass between V2 and the sea wall to the east. Visually to V2's crew, V1's course correction to rectify his approach using propulsion was too late in order to avoid a collision with V2. 
  
  V1's starboard side, center-line hull (fiberglass), impacted the starboard bow corner (steel construction) of V2. Significant damage occurred with the impact to VI. There was no damage to V2. There were no injuries on either vessel due to V1's impact of V2. 
  
  *** Vi is a USCG Documented vessel that has failed to properly register with the State of Florida, home port is marked as Delray Beach on the stern as required. VI also violated USCG Navigation Rules that ultimately led to the accident Rule 7 (a) & (c) "Risk of Collision", Rule 8 (d) & (e) "Act to Avoid Collision" and Rule 16 "Action by Give-Way Vessel". Due to the significant damage to V1, verbal warnings were issued to OP1.
