Searching rooms

Skill used: Observation for the cursory look. Search for most of the others.

The normal times to do different types of searches in time/square:

	*  1 second: Cursory look: basically see objects behind other objects and the like. The type of search you do to see if someone left their purses or jackets or similar after a event..</description>

        <description>Alternate Delta-v for tanks

By Richard Maw

delta-v = 20 × delta-v-per-tank × ln(20 ÷ (20-tanks))

to get number of tanks needed:

tanks = (20-(20 ÷ e^(delta-v ÷ (20 × delta-v-per-tank))))

        <description>Fixes

This section is a bunch of house rules aimed at explaining things that are unclear/seem wrong in spaceships.

External clamp

(ss:15)
Is very vague on details. So it seems is that an external clamp can hold the mass of the ship with the clamp at any acceleration expected of the given Tech level.  It is even then way too massive. So for my games I use smaller clamps as follows:</description>

These are modifications to existing modules over and above the ones in the originals.

Armor

New Armor types:

Beam-Adaptive Armor (UT 190): at $2 million/ton it will be very rare, but allows 3x the normal DR against one type of damage.</description>

These are new optional systems you can add to the spacecraft.

Maneuver thrusters

(TL7)[Hull]

In some settings some craft are very nimble compared to other craft. Such craft can buy the maneuver thruster system. Select a reaction and reactionless drive you wish to use as thruster in your setting. The drive is instead a huge number of small drives spread all around. The cost, workspaces, energy use and such are as for the normal drive.  Typically the system is built on a high thrhu…</description>

The following values/power point for different sizes are calculated from the weapon damages with the base weapons being 25% efficient and one shot/20 seconds and the improved versions as 50% efficient to get the extra rof with same energy.</description>

        <description>Gurps Spaceships Unofficial Companion

An unofficial addendum to the GURPS spacehips series 

Introduction

Gurps spaceships series of PDFs provide a fairly simple system for making spaceships for science fiction games in the Gurps system.  This document is meant to give more options and ideas to builders.</description>

        <description>System size

The base system assumes that each subsystem is 1/20th the total ship mass. However it is fairly easy addition to have modules of different sizes. Below are working rules for adding smaller or larger subsystems to ships. 

Not all systems can be different sized. Note that the SM of subsystems does not indicate the SM of the system, instead it indicates the size of the craft where that system is “normal sized” and thus 1/20 of the ship mass.</description>

Ammo weight/capcity

Ammunitions weights for 10mm guns: 10mm CLP is listed as 0.014lbs which is 98 grains a modern day 10mm round has 155-200gr for the bullet alone. In addition to that there is some weight for the propellant.</description>
