Sunset Dawn
General
Originally build as the Antelope, the Sunset Dawn is a three masted Barquentine, that means the fore mast is square rigged, and the main and mizzen are fore and aft rigged. The hull is made from steel, and the spars are all made out of carbon fibre.
The deck is steel with impregnated softwood planking glued ontop of it. Also the top of the deckhouses are covered in this wood.
Nameing

Aurora
Sunset Dawn
The name Sunset Dawn was thought up by captain Peter James Jacobson, It's a contradiction as dawn ofcourse happens at sunrise and not sunset. It's a jest towards the hidden nature of the ship, being a pirate vessel but often posing as a superyacht.

Power Generation
Propulsion
Main propulsion:
4.613,36 m² / 49.657,79 sq.feet sail area (excluding light weather extra sails)
Auxiliary propulsion:
Two Yanmar 4-stroke marine diesel engines of 1.340kW / 1.822 HP @ 1.940 rpm each.
Type: 12AYM-WGT
V-12 direct injection, turbocharger & intercooler.
On variable pitch propellers.
Consuming 300 L/h each at full load.
Weapons & Armament
24 guns on the gun deck (12 on each side)
Rheinmetall Rh120 L/55 mounted on a carriage positioned rails so that they can slide in and out trough gunports in the side of the ship.
The elevation is limited to +10° / -6°
There is no side to side movement possible.
The Sunset Dawn does not posses over a fire control system, also the guns not stabilized. The gun's are aimed by sight of the crew, elevation is set by hand driving gears.
The gun carriage is pushed out / pulled back by an electric winch. The recoil is caught in the gun's own recoil system, the carriage has brakes that clamp onto the rails during fireing.
The guns can be fired from stored position, fully pulled back, position, as long as the gun port is opened. The only downside of this is that a lot of smoke is caught in the gun deck. As the muzzle is a few centimetres behind the gun port in this position.
Additional & auxiliary systems
hydraulic winches for sail handeling.
Manual powered Capstan, but unliked traditional capstans, there is no rope leading to it. It drives a hydraulic pump, charging a accumilator, that then can be used for the winches.
Hangars & docked vessels
Both with two 100hp outboard engines.
Helm station with two seats behind it, and four seats in front. while still having ample deck space for other passengers. Extra rubstreaks around the foam filled heavy duty tubes. The tubes are covered with antislip material to aid the crew. The engines are protected with a bar that wraps around them in the stern connected to the A frame. A tow point in the stern and sturdy mooring bolder inthe bow.
Two lifting points for connecting to the davits. Single operating from the helm station to release lifting points.
After making the gunports, maximum cargo load has been reduced to 1.200 mt.
Values at minimum draft (T= 4,45 m)
Sheer values at stations
Mast postitions
Measured along the deckline. (Aft of Fpp)
So cool! What is the relationship between freeboard and draft? Is draft below the waterline?
Thank you
The vertical distance from the keel to the deckline is the (moulded) Depth.
The distance between keel and water line is Draft.
The distance between the waterline and deckline is freeboard.
Depth = draft + freeboard.
