There are two ways to make your gear stronger: in the Shipyard's Upgrade section you raise decks and cannon kinds grade by grade, and in Mastery you master each cannon, armour and sail with gold alone. Both add up.
Deck grades#
Each ship's deck can be reinforced up to grade 4; each grade adds +6% to that ship's hull. The grade belongs to the ship: on another ship its own grade counts.
| Ship | 1 → 2 | 2 → 3 | 3 → 4 | Total |
|---|---|---|---|---|
 Sloop |  10,000 | 20,000 | 35,000 | 65,000 |
 Brig | 30,000 | 60,000 | 105,000 | 195,000 |
 Schooner | 70,000 | 140,000 | 245,000 | 455,000 |
 Frigate | 160,000 | 320,000 | 560,000 | 1,040,000 |
 Galleon | 340,000 | 680,000 | 1,190,000 | 2,210,000 |
 Man-o'-War | 1,200,000 | 2,400,000 | 4,200,000 | 7,800,000 |
Cannon grades#
Each cannon kind is graded on its own, and every gun of that kind you own gets stronger together. Gold guns are graded with gold, crystal guns with crystals.
| Cannon | Per grade | 1 → 2 | 2 → 3 | 3 → 4 | Total |
|---|---|---|---|---|---|
 Bronze Cannon | +13.3% | 6,000 | 12,000 | 21,000 | 39,000 |
 Iron Cannon | +12.2% | 25,000 | 50,000 | 88,000 | 163,000 |
 Steel Cannon | +11.1% | 120,000 | 240,000 | 420,000 | 780,000 |
 Royal Cannon | +8% | 700,000 | 1,400,000 | 2,450,000 | 4,550,000 |
 Dragon Cannon | +11.5% |  60 | 120 | 210 | 390 |
 Kraken Cannon | +8% | 150 | 300 | 525 | 975 |
Mastery#
Every cannon kind, armour and sail you own can be mastered from +1 to +10. Mastery is bought with gold only and every level costs more than the last: a long-term goal for your gold. From level 20, a red count on the Shipyard button tells you when your gold covers a mastery.
