Deep Blue 80 electric outboards for Ophart workboats

A German company has developed a new approach to building workboats. Instead of doing the whole of the construction in a boat yard, Ophart Maritim builds a range of hulls in aluminium and supplies these to owners or other shipyards for completion and fitting out.

The Opship hulls are supplied as the basic open hull, what the company calls a Boat Chassis, which gives the recipients a proven design on which to develop their own ideas for the completed vessel.

The aluminium hulls are designed in three sizes and they are all based on a unique hull design that features a moderate vee hull with wide chines for easy planing. There is a deep narrow forefoot to improve the low speed handling and a flare in the bow to provide a dry ride.

The hulls are primarily designed to accommodate outboard power with up to triple 300 hp outboards on the largest of the hulls to give high speeds. To fit these power units a bolt-on module is attached to the transom. Fuel tanks can be specified if required. Alternatively the hulls can be specified for electric propulsion using the range of Deep Blue 80 electric outboards produced by Torqeedo and with a battery pack to offer range of over 50 miles at low speeds but with the larger electric outboards, a speed of 12 knots can be achieved but with a more limited range.

The aluminium hulls are fully welded using 8 mm plating and fitted with closely spaced transverse framing. This framing is both welded and glued in place, the glue creating a form of insulation that is designed to reduce the sound. An interior deck can be supplied over the frames or these can be left exposed for the final builder to complete as required.

The concept of the hulls developed by Ophart Maritim is to offer an advanced and tried and tested hull concept at an attractive price. These hulls are designed to meet the demands for a wide variety of workboat roles from fast patrol boats to rugged harbour workboats. They are currently produced in sizes from 8 metres up to 12 metres and one of the main advantages is the quick delivery time. Also by focussing on just producing hulls in aluminium Ophart is able to invest in advanced construction techniques.
