The 5 Most Expensive Mistakes

1

Underinsuring Your Boat

Setting a sum insured that's too low to save on premiums

❌ Consequence

Inadequate payout in total loss situations, leaving you financially exposed

✅ Solution

Use professional valuation or recent sale prices for similar boats

Potential Cost: Could cost $10,000s in uncovered losses

2

Ignoring Navigation Limits

Not understanding where your policy covers you to operate

❌ Consequence

Claims denied if accident occurs outside covered navigation area

✅ Solution

Clearly understand your navigation limits and extend if needed

Potential Cost: Entire claim could be denied

3

Choosing Wrong Excess Amount

Selecting very high excess to lower premiums without considering affordability

❌ Consequence

Unable to afford excess when claim arises, delaying repairs

✅ Solution

Choose excess you can comfortably afford in emergency

Potential Cost: Could delay critical repairs by months

4

Not Disclosing Modifications

Failing to notify insurer of engine upgrades, electronics, or structural changes

❌ Consequence

Policy void or reduced payout due to non-disclosure

✅ Solution

Declare all modifications and upgrades promptly

Potential Cost: Policy voidance or reduced claims payout

5

Assuming "Agreed Value" Means Guaranteed Payout

Misunderstanding how agreed value policies work in practice

❌ Consequence

Disappointed when market depreciation affects claims settlement

✅ Solution

Understand policy terms and review agreed value annually

Potential Cost: Significant shortfall in total loss payout
