  • Description
    Built tough to work hard for rugged private and commercial use. The Achilles SU Sport Utility boats are made with an additional heavy-duty layer of 840-denier nylon Achilles CSM fabric in a two-ply technique which results in a fabric even stronger than a single base fabric of equal thickness. A number of commercial grade features such as recessed valves and a full-length, protective wear patch combine to make these boats the right choice for the toughest marine uses.
     
    The Achilles SU-18 inflatable boat is the largest of the SU sport utility series. This is a very rugged craft designed for commercial, rescue, and utility operations. Recreational activities requiring a vessel that support heavy loads suit this inflatable, since it can support up to 4,630 pounds, over two tons. Top features include a heavy duty rigid deck system, recessed valves, bailer sleeve and a full chafe guard. With the use of a 90 horsepower outboard, this boat can successfully plane with up to 11 persons.

Additional Prep/DMV Info

Dealer Engine Prep

Dealer Engine Prep is required to validate the warranty and ensure a working engine. Prep includes completing a full Original Equipment Manufacturer (OEM) checklist, test-run performed in a tank for quality assurance, and re-crating for shipment. Outboards picked up in-store may be stand-alone and no longer in the box or crate.

Pre-Delivery Inspection

Pre-delivery Inspection is required to validate the warranty and includes the necessary services & products used on each new vessel to ensure quality performance prior to delivery.

For rigged vessels: Boat Specialists will install a deep cycle marine battery, rig all steering components, and complete an electrical and systems check. A full system check includes filling the motor with oil, fluids, and fuel, then a test run performed in a tank for quality assurance.

Once everything is tuned and prepared, a sea trial is performed to achieve the ideal RPM-to-top-speed ratio, ensuring the boat gets on plane properly and all systems operate on water. Afterward, full detail is performed on the exterior, deck, and hull to be turn-key ready for the customer.

DMV Registration On Boats and Trailers - For California Residents Only

Boat Specialists will take care of your CA DMV registration including signing a Power of Attorney for each registration. We will mail temporary paperwork with the documents that require the customer's signature. The customer is to sign and return the documents in the envelope provided. Once we have received the paperwork, we will submit all required documents to the DMV to complete registration.
