Sailboat

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
100 lb	SS	1 round	50	11	-

The smallest stellar ships, sailboats can be crewed by a single person. These ships often transport small amounts of cargo or passengers. They're perfect for pleasure cruises, as they're easier and less expensive to operate than larger vessels. Sailboats are defined by having only one mast and by being far too small to host an Aetherscopic Engine.
Travelling to other islands is possible in a sailboat, though it leaves one entirely at the mercy of solar winds.

Cutter

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
500 lb	SS	1 round	100	12	-

The difference between a cutter and a sailboat is hard to tell for those unfamiliar with ships, but a close examination will reveal that cutters are longer, with their mast proportionally much closer to the bow. This layout, combined with the small size of a cutter, makes cutters extremely maneuverable compared to other ship designs. Most cutters are large enough to have an enclosed cabin, a luxury that sailboats lack.
The maneuverability of cutters in conjunction with their inexpensive cost make cutters a popular choice as patrol boats. A common sight when nearing an island is a handful of cutters patrolling the area.

Corvette

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Threshold
2 tons	SS/AE	2 rounds	175	13	5

Corvettes are the smallest type of ship capable of holding an Aetherscopic Engine. Most corvettes available for purchase have two masts, both filled with solar sails to feed the engine. Most corvettes are typically found in military service, but it's not uncommon to find corvettes converted into fishing vessels, with the engine replaced with cargo space for the fish.

Clipper

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
7 tons	SS/AE	3 rounds	250	13	10

Clippers are the most common vessels seen in Astaria, and are instantly recognizable with a distinctive narrow profile and a clean deck layout. Clippers are defined by having three masts, which makes for a very quick vessel, at the cost of some maneuverability.
Most ships created before the discovery of solar sails were clipper-sized or smaller.

Schooner

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
18 tons	SS/AE	4 rounds	400	14	15

Schooners are a versatile ship, being well-suited as merchant vessels, naval ships, and even yachts. Their medium size enables them to be outfitted to nearly any purpose.
Schooners have four masts, and a lean profile.

Frigate

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
30 tons	SS/AE	6 rounds	600	15	20

Frigates are large merchant vessels, designed to carry massive amounts of cargo over long distances.
Frigates have five masts,

Galleon

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
50 tons	SS	5 rounds	500	16	20

Most navies in the galaxy are made up of galleons, as they represent the pinnacle of naval might for systems not in possession of a dreadnaught. Galleons have tall, wide hulls, and are shorter in length than other comparable ships.
Galleons are also popular with pirates, as their large hulls can hold lots of cargo in addition to their naval might.

Steamer

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
80 tons	AE	8 rounds	700	15	15

Steamers are the largest merchant ships in Asteria, combining a large length with a massive cargo capacity. A steamer is the largest size a ship can go and still be made of wood.
Unlike smaller ships, steamers don't require solar sails to supplement their engines - steamers are large enough to have an entirely self-contained Aetherscopic Engine.

Dreadnaught

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
150 tons	AE	1 minute	1500	17	25

Owning a dreadnaught firmly establishes oneself as a major naval power in Asteria. These ships are immensely powerful, being capable of laying siege to small islands single-handedly.
24 Thaums of the dreadnaught's power have been set aside for weapons.

Carrier

Cargo Capacity	Propulsion	Turn Time	HP	AC	Damage Treshold
230 tons	AE	2 minutes	1200	16	20

Carriers are the largest - and most expensive - ships currently sailing through the galaxy. Only a handful of carriers exist, none of which have yet been proven in combat.
Carriers, as their name would imply, can hold smaller ships within them - each carrier has enough power to carry up to 60 thaums worth of ships. For example, a carrier can hold up to 12 corvettes, or 3 frigates.

Ship Upgrades

Ships aren't made in a vacuum, and the shipyards at Ecumenopolis are more then willing to refit, modify, and alter your ship to your needs. As shown in the Power sidebar, ships can accommodate any number of upgrades so long as the ship has excess power slots remaining. Each upgrade has a gold cost and an amount of power it will require, as shown in the Gold and Power columns, respectively. Here are some upgrades you can have installed on your ship:

Shields	3	5000	Shields are the pinnacle of large-scale abjuration magic, creating a magical barrier that surrounds the entire ship. Each Shield adds +1 to a ship’s AC, up to a maximum of +3.
Armor	*	*	Armor is an extra layer of defense for the ship, making it more resilient to damage. Armor takes up 1/8 of the ship’s slots (rounded down), and adds 50 hp to the ship per slot used. Armor costs 500gp per slot used.
Warp Drive	10	20000	When you use this module, the ship spends 1 minute activating the module before teleporting the ship and its occupants to a previously designated location. You may designate a location by spending 12 hours configuring this module while the ship is stationary.
Naval Ram	1	1000	When installed, the ship has advantage on all saving throws relating to crashing when it crashes into a creature or an object. Any damage it takes from the crash is applied to the naval ram rather than to the ship. These benefits don't apply if another vessel crashes into the ship. On a hit, the ram deals 1d6 damage for each Power slot the ship has.

Target: This weapon fires a single projectile towards a 5ft square target. On a hit, the target takes that much damage, and any creatures in the square must make a DC 15 Dexterity saving throw. On a successful save, the creature takes half damage.

Line: This weapon fires in a straight line, with the radius of the line determined by the weapon. Every creature in the line must make a DC 15 Dexterity saving throw. On a success, the creature takes half damage.

Area: This weapon affects a large circular area upon impact, with the radius of the circle determined by the weapon. On a hit, the target takes that much damage, and each creature within the area of the impact must make a DC 15 Dexterity saving throw. On a success, the creature takes half damage.

Parts of a Ship

Crew

Each ship requires a minimum amount of crew to run, as defined in the Crew column. You don't need to worry about paying them; part of the initial payment for the ship goes towards hiring their services for the duration.

Passengers

Each ship can carry a set number of passengers, as defined in the Passengers column. Smaller ships tend to have more cramped quarters for the passengers, but larger ships can afford to have private rooms for each.

Cargo

The table indicates the maximum tonnage each ship can carry.

Propulsion

Each ship is powered by either solar sails (SS) or an Aetherscopic Engine (AE). Certain ship types can be powered by either, or both. Ships that are powered by both don't use solar sails as propulsion, but rather as a means to generate power for the Aetherscopic Engine.

Turn Time

This column indicates how long it takes for the ship to turn 90° when traveling at full speed. Smaller ships can generally turn faster than larger ships.

Damage Threshold

Most ships are too large to be affected by small weapons, and the damage threshold reflects that. A ship has immunity to all damage unless it takes damage equal to or greater than its damage threshold. Damage that fails to meet its damage threshold is considered superficial damage and doesn't reduce the ship's hit points.

Power

Every upgrade applied to a ship requires a base amount of magical power to function. One unit of magical power is referred to as a Thaum, and is enough to propel a small sailboat. As shown in the Power column of the ship table, ships can produce several Thaums on their own, through either solar sails or an Aetherscopic Engine.
Most ships produce thaums far in excess of what is needed to propel the ship, but propulsion isn't the only thing a ship needs. These excess thaums can be used to power auxiliary functions, such as cannons, shields, and even recreational activities. Merchant vessels may have refrigeration modules installed, for instance, whereas larger vessels may even have amenities such as lounges and bars.
