I've iterated it down to 700 tons (so far).

The Traveller5 definition of "Frigate", in brief, is "more guns than armor". A fuzzy definition, but I take it to mean it's not meant to stand in a line of battle, even a small one. Rather, it's meant to thoroughly intimidate unarmored vessels, or something like that.

I've only got one shift accommodated; I decided against three shifts... but argue with me.

Edit: Comments on 800 Dt ship:

Landing legs with wheels (and pads) included free with airframe configuration (B2p72)?

Structure Charged not available with configuration Airframe (B2p72)?

Jump Fuel = 800 × 20% × 80% = 128 Dt?
PP Fuel = 7 × 800 × 80% × 2 = 89.6 Dt?

Drives dimensioned for a 200 Dt hull, not 800 Dt? Should be J-drive H and M-drive Z?

Sensors apparently mounted in T2 Ext mount, so takes hardpoints? Hence the ship uses 18 hardpoints of 8 available?

A Missile in a Deployable Double Barbette mount costs MCr 2 + 4 + 3 = MCr 9, three mounts costs MCr 27?

Grapples: 3 Dt per 100 Dt gives 24 Dt for 800 Dt?

Wheels only; I prefer landing legs, which are "possible" (+).

Good catch!

Jump Fuel = 800 × 20% × 80% = 128 Dt?
PP Fuel = 7 × 800 × 80% × 2 = 89.6 Dt?

The software may have rounded up a few tons. Call it "safety margin"?

Drives dimensioned for a 200 Dt hull, not 800 Dt? Should be J-drive H and M-drive Z?

Good catch. Software again; stage affects must short-circuit when I change hull size.

Sensors apparently mounted in T2 Ext mount, so takes hardpoints? Hence the ship uses 18 hardpoints of 8 available?

Extensible antennae, not turret mounts.

A Missile in a Deployable Double Barbette mount costs MCr 2 + 4 + 3 = MCr 9, three mounts costs MCr 27?

Perhaps my data is out of date; it says AR B2 deployable missile is MCr 7.2.

Grapples: 3 Dt per 100 Dt gives 24 Dt for 800 Dt?

35t per pair; thus, 6 Dt per 100 Dt, roughly.

*CORRECTION* B2p87: For subhulls, 3 pairs per 100 tons, exactly. I.E. 6 grapples per 100 tons.

Wheels include the functionality of pads:

B2p53 said:
Landing Wheels. The ship has retractable landing legs terminating in wheels. The hull may land anywhere that Landing legs with pads can, but for the wheels to be usable, a landing strip is required.

robject said:
Extensible antennae, not turret mounts.

Extendable only applies to turret and barbette mounts:

B2p58 said:
An Extendable Mount (only Turret or Barbette) is attached to a telescoping arm; ...

robject said:
Perhaps my data is out of date; it says AR B2 deployable missile is MCr 7.2.

Without stages or range effects, you just add up the weapon (MCr 2), the mount (MCr 4), and the mount modification (MCr 3), sum MCr 9. See B2p57-58.

*CORRECTION* B2p87: For subhulls, 3 pairs per 100 tons, exactly. I.E. 6 grapples per 100 tons.

Each half of the pair is installed in the carried hull, hence 3 Dt per 100 Dt in each of the carried and the carrying hull.

B2p70 said:
Grapples. One Grapple set consists of two 1-ton Grapples (one on the Pod, Barge, or Subhull; one on the parent hull). One set is required for each 35 tons of Pod, Barge, or Subhull.

In the modern context, frigates are specialized platforms, usually defensive roles, slower and smaller than destroyers, or a large general purpose ship, kinda ersatz destroyers.

At eight hundred tonnes, this would be more a corvette.

Customs and revenue services seem to prefer cutters.

A Jump Drive can't be smaller than 10 Dt.

An Adv Jump Drive B is 10 Dt and MCr 20?

B2p77 said:
No drive may be smaller than the Drive-A of the class, even after modifications like Stage Effects.

A Power Plant-F is 19 Dt. Cost is MCr 1 / Dt. Adv stage is 1/3 the volume and twice the cost.

Volume: 19 / 3 = 6.333 Dt.
Cost: 6.333 Dt × 1 MCr/Dt × 2 = MCr 12.667?

See example B2p47.

Four layers of armour should consume tonnage, only the first layer is free?

Your ship lacks life support (B2p87, Table C) and Control Consoles.

Pilots and gunners needs control consoles; presuming a CC for the pilot and a spare CC on the bridge, the gunners have a single CC to share which seems impractical?

Shouldn't a customs ship have a small craft to dock with civilians? I assume we do not want to routinely dock with unknown ships?

I get something like:

I'm not familiar with Ship Construction beyond CT High Guard, so I'll look at the intended use of the ship. Are you planning to chase off pirates? Board merchantmen to check that their papers are in order? Visit Belters on asteroids? Enforce quarantines / starport lockdowns? Answer distress calls? Does it need Jump capability? All of these will influence the equipment your ship must carry. I see a small craft that can carry a squad of Marines as a must; also a 6-G runabout to move emergency supplies fast.

Any IRL resources (books) you can find about Coast Guard life and duties would likely help you create a ship you are happy with.

"more guns than armor" ... it's meant to thoroughly intimidate unarmored vessels, or something like that

or tempt some smuggler to get in the first shot ...

I've only got one shift accommodated; I decided against three shifts

then it will be scut duty taken only by low-rated, deficient, or retired-on-the-job personnel, or possibly by dedicated patriots.
