Boston Whaler

Setting up a boat lift for your 2018 Boston Whaler Conquest 285 requires attention to the size, weight distribution, and hull design of the boat. The Conquest 285 has a length of 28'8", a beam of 9'6", and weighs approximately 8,100 lbs dry weight (without fuel, gear, or passengers).

Key Steps to Set Up the Boat Lift

1. Bunk Spacing (Wood Beams are 4" x 8") 

• The bunks should align with the flat, reinforced portion of the hull (typically the chines or stringers).
• For a Boston Whaler Conquest 285, a general rule is:
  • Outer bunks: Spaced approximately 3-4 feet apart (measured center-to-center).
  • The bunks should support the outer hull near the chines without contacting the hull's V-shape.

2. Bunk Length

• Use 12-foot bunks or longer to ensure proper weight distribution.
• Longer bunks will provide extra stability and reduce pressure points on the hull.

3. Bunk Angle and Position

• Adjust the bunks so they match the hull's deadrise (approximately 20° on the Conquest 285).
• Use adjustable brackets to angle the bunks and ensure maximum contact with the hull.

4. Weight Distribution

• Position the lift's cradle so the boat's center of gravity aligns with the lift center. On the Conquest 285, the center of gravity is roughly:
  • Midships, slightly aft of the midpoint due to engines and fuel tanks.
• The weight should be evenly distributed across all bunks.

5. Bunk Material

• Use marine-grade lumber or aluminum with carpet or composite covers to protect the hull.
• Avoid sharp edges or protrusions that could damage the boat.

6. Load Capacity

• Ensure the boat lift's capacity exceeds the Conquest 285's fully loaded weight:
  • Dry Weight: ~8,100 lbs
  • Add fuel (200 gallons at ~1,400 lbs), water, and gear: Total ~10,000–11,000 lbs
• A 12,000-lb capacity lift is recommended.

7. Guide Poles

• Install guide poles or PVC pipes to assist in centering the boat when docking. Place them near the bow and stern.

Next Steps:

• Consult the Manual: Refer to Boston Whaler’s official specifications and diagrams for weight distribution points.
• Contact the Lift Manufacturer: If you have a specific boat lift brand, their customer support can recommend bunk spacing for your Conquest 285.
• Hull Map: Boston Whaler or a dealer can provide a hull diagram to align bunks correctly.
• Professional Setup: Consider hiring a boat lift specialist to avoid damage.
