Player workbench

Find the Broadside Cannons Number Ultimate Plan at The Blue Hole when a stable side-on pass needs a fuller salvo.

If the Jackdaw sinks before firing, hull strength or approach is the blocker; if a clean side-on pass fires too few guns, the cannon-number lane is relevant.

Why this entry is useful

A cannon-count-versus-survival choice, Blue Hole wreck dive and same-angle firing test.

The Resynced wreck lead is The Blue Hole around 440, 145, not the older 471, 170 point or San Ignacio's hull route. Verify the live wreck, pickup and harbourmaster menu.

Safe first move

Check that the Jackdaw survives and reaches broadside range, then read the Cannons Number menu line before sailing to The Blue Hole.

Finish line

Broadside Cannons Number Ultimate Plan appears by name and a repeated side-on pass shows whether the larger salvo, not positioning, was the needed change.

How to use it

The two wreck plans are not interchangeable

The Blue Hole cannon-number route answers a fuller-salvo need; San Ignacio hull armor answers survival. Confirm the exact Ultimate-plan name and ship symptom before another dive.

Recovery path

I found hull armor instead

If the wreck pickup is hull armor or the Blue Hole marker is absent, keep that result separate and read the current cannon-number menu hint. If the plan installs but the salvo still underperforms, repeat a side-on firing line before shopping again.

Salvo need → Blue Hole dive → firing test

Before the dive, separate a short salvo from a ship that dies before firing or cannot close range; only the first makes this plan the immediate lane.
Use The Blue Hole wreck marker and diving-bell access around 440, 145; San Ignacio is the separate hull-armor dive.
Confirm Broadside Cannons Number Ultimate Plan by name, inspect install prerequisites, then compare the same firing pass before spending on another lane.

Route Plan

How to use Broadside Cannons Number Ultimate Plan – The Blue Hole

Use The Blue Hole wreck for the Broadside Cannons Number plan, not the San Ignacio hull-armor route. Confirm the dive marker near 440, 145 and the named underwater pickup before paying for the final cannon-number upgrade.

If the Jackdaw survives and reaches side-on range but needs a fuller salvo, inspect the Broadside Cannons Number line; sinking early needs hull or positioning first.
Check diving-bell access at The Blue Hole around the Resynced 440, 145 wreck lead; San Ignacio is the separate hull-armor lead.
Read the exact underwater pickup and harbourmaster menu names, then retest the same broadside angle after any install.

Save Checklist

Use these checks before marking Broadside Cannons Number Ultimate Plan – The Blue Hole complete.

Entry type: Jackdaw Upgrade.
Recommended check: Check Jackdaw menu.
Main risk: A San Ignacio repeat dive cannot prove a Blue Hole broadside pickup and can waste both route time and materials.
Confirm the marker, reward, or requirement in the current Resynced build.
Open next: jackdaw upgrades.

Upgrade Lane

Treat this as a ship-power decision, not just a map pickup.

Confirm whether the upgrade improves storage, armor, broadside, mortar, ram, fire barrel, harpoon, or heavy shot power.
Use 440, 145 for the map check before leaving port.
Match the upgrade lane to the naval fight that is actually blocking you.

Before Spending

The Jackdaw menu should decide whether this route is worth the sail.

Check whether the upgrade is already installed or still locked.
Compare the plan against your current failure: sinking, low damage, weak range, bad approach, or storage pressure.
Group nearby treasure maps and location checks into the same route.

Naval Retry Prep

Use the upgrade only when it changes the next sea fight.

Restock ammunition before retrying forts, contracts, or legendary ships.
Use mortars for safer openings when close approach is the problem.
Return to Naval after the plan is installed so the fight route matches the new ship power.
