1. I do feel that per the breakaway hull instruction that 2% of the combined hull is required for the extra bulkheads and connectors for should have been applied the the combined 400 ton hull not the combined pod displacement tonnage. I would also like to suggest that the 2% be applied to all of the breakaway hull sections instead of just the combined hull.
Maybe this should have been made clearer in High Guard but it should be 2% on each breakaway section per connection, so if say a 400 ton hull has two 100 ton breakaway sections that connect to it this would be 2% of 400 x2 and 2% of each 100 ton section.
From HG 2e page 12/PDF page 13;"....This whole process consumes 2% of the combined hull tonnage for the extra bulkheads and connectors needed, and costs an additional MCr2 per ton consumed. Hull points of each section will be proportionate to the total Hull points of the ship."

I feel that the instructions are very clear that the extra bulkheads and connectors are 2% of the combined hull and based on the hull point instructions each section's extra bulkhead and connector tonnage can also be calculated separately.

1. Extra bulkheads and connectors
The combined Fessor 400 ton hull requires 400 c 0.02 = 8 tons.

The Fessor's 204 ton core hull requires 204 x 0.02 = 4.08 tons of extra bulkheads and connectors.
A 49 ton pod requires 49 x 0.02 = 0.98 tons of extra bulkheads and connectors. With all four pods attached the total is 3.92 tons. Core hull 4.08 tons + 4 pods 3.92 = 8 tons.

2. Hull points
A combined 400 ton hull has 1 hull point per every full 2.5 tons of hull for a total of 160.

Each 49 ton Pod has 1 hull point per every full 2.5 tons of hull for a total of 49 / 2.5 = 19.6 round down to 19 ( 19 x 2.5 = 47.5 tons leaving 1.5 tons which is not a full 2.5 tons). The combine pod hull point is 19 x 4 =76.

A 204 ton hull has 1 hull point per every full 2.5 tons of hull for a total of 204 / 2.5 = 81.6 round down to 81 (81 x 2.5 =202.5 leaving 1.5 tons which is not a full 2.5 tons).

Combining the core hull points of 81 + 4 pods combined hull points of 76 = 157 hull points which means we are missing 3 hull points. The combined pod tonnages is 49 x 4 = 196 / 2.5 = 78.4 hull points rounding down the 78 + 81 = 159 hull points, which is now off by 1 point from the combined 400 ton hull.

Oops I forgot to correct the count for my possible errata and as another question concerning the Fessor core hull's power plant fuel requirement.

Shouldn't the 2 tons actually allow the power plant to operate for 8 weeks?
Don't know the size of the power plant, but for fusion power plants it should be 10% rounded up per 4 weeks. So say a 12 ton power plant would require 2 tons for 4 weeks, 4 tons for 8 weeks.
The Fessor's core hulls power plant is 17 tons x 0.1 = 1.7 (rounding up, minimum of 1 ton) = 2 tons of fuel and is listed as being able to operate for 4 weeks.

In other versions of Traveller 1 ton of fuel allows for 4 weeks of operation

At first the instruction for power plant fuel on HG 2e page 17/PDF page 18 of "Other power plants require fuel tankage of 10% of their size (rounding up, minimum of 1 ton). This provides enough fuel for the power plant for a month (four weeks)...." seem to indicate the same requirements.

I've just taken a quick look at the examples in HG 2e and they appear to indicate that the Power Plant x 10% rounding up, minimum of 1 ton results in 4 weeks of operational duration.

Yes, it is 2% of the combined, just split between the hulls as it is needed on both sides (which is what isn't entirely clear).

I'm thinking that to make the instructions clearer the text might be re-written as something like "each breakaway hull section requires 2% of its hull tonnage for extra bulkheads and connectors"
