Which block type gives the best balance between weight and defense?
This chart shows the weight and defense value of each block type side by side, so you can easily compare which materials give you the best protection without making your boat too heavy.
Balance is key when building your boat
This chart shows that metal blocks offer the highest defense but also come with high weight. If you want to stay “safe” and still float well, combining lighter and stronger blocks is often the best strategy.

Block stats compared
Here’s a quick comparison of the three most common blocks:
| 🧱 Block Type | 🛡️ Defense | ⚖️ Weight | 🪙 Cost |
|---|---|---|---|
| Wood | 1 | 1 | 5 |
| Metal | 5 | 4 | 10 |
| Gold | 3 | 2 | 15 |
Example: 3-block combo
10x Wood, 5x Metal, 2x Gold
Total blocks: 17 • Total defense: 41 • Float rating: Safe ✅
Tip: Light builds float better!
Too much weight can make your boat sink. Try mixing block types to stay balanced.
How much does each block affect your boat?
Different blocks have different effects on how strong and heavy your boat is. Here’s how they compare when you use more of them:
| 🔢 Amount | 🧱 Block Type | 🛡️ Total Defense | ⚖️ Total Weight |
|---|---|---|---|
| 20 | Wood | 20 | 20 |
| 10 | Metal | 50 | 40 |
| 5 | Gold | 15 | 10 |
When to use which block?
This guide helps you choose the right material depending on your goal:
| 🧭 Goal | ✅ Best Block | 💡 Why? |
|---|---|---|
| Light and fast | Wood | Low weight, floats well 🟢 |
| High defense | Metal | Survives more hits 🔩 |
| Balance of both | Gold | Medium weight & defense ⚖️ |
Smart tip: Mix your layout!
Use metal for the bottom, gold in the center, and wood on top. That way, you float better and still survive some hits!
Scenario: Sinking risk too high?
Total weight over 60
You might get a “Too heavy” rating. Try replacing some blocks with wood.
Can you make the perfect boat?
There’s no perfect answer – but this calculator helps you get really close. Try different combos and see how your stats change. More defense? Less weight? It’s up to you.
Quote: Simple boats often work best
“Don’t overthink it. Sometimes 15 wood blocks float better than 30 gold ones.”
