• For any stat that progresses x10 for +3 SM, multiply the stat by the square of the cube root of the ratio of mass to that of the next smaller official hull.
• For any stat that progresses x10 for +2 SM, multiply the stat by the ratio of mass to that of the next smaller official hull.
• For any stat that has a linear progression, use the stat of the smaller official hull if the mass ratio is less than 1.8, and that of the larger official hull if the ratio is 1.8 or larger.
• Be careful that many stats have substantial rounding or minima at the low end. It may be necessary to figure out the progression and calculate a theoretical value for your base hull, the reapply the rounding and/or minima after modifying for your actual hull. For example, SM+6 habitat should have 0.6 cabins.

So a 260 ton vessel would have 1.37 times the DR, 1.89 times the open spaces areas, and 2.6 times the cargo capacity per component of a 100 ton ship, and would have the handling and computer complexity (and SM) of a 300 ton ship. There are a few odd progressions, like hangar bay launch rate (though if you look carefully, you may note that if you express launch rate as seconds per hangar, you get a neat x10/+6 progression).

works for me. :)
