Boat Trailer Bunks and boat trailer blocks are the exact same identical item. Some trailer manufactures and resellers simply call them by different names. The end result, Bunks, Blocks, Planks, Slides they are still the same item.

If you notice worn carpet, exposed wood, cracks, soft spots, or your boat doesn’t sit level on the bunks, that’s a sign. These issues mean the bunk’s protective layer is compromised. Replacing damaged boat trailer bunks helps prevent damage to your boats aluminium & gel coat scratching and keeps your hull properly supported.

Bunks should be aligned under the boat‘s stringers or other strong hull points. Space them so there’s even support from front to back. Too wide a gap can cause hull sagging, while too close increases friction. Correct spacing ensures even weight distribution and reduces hull stress.

Length: Boat Trailer Bunks should at least cover the distance between your trailers cross sections. This ensures your bunks are well supported using the correct brackets and hardware.

Hollow Boat Trailer Bunks are often imported from overseas.

Hollow bunks are often weaker in design. Cracking and splitting is common in hollow bunks when a boat connects with the corners of the plastic profile. Manufacturers of hollow bunks try to reinforce the bunk with lengths of aluminium however, If and when the bunks do split the aluminium can be exposed and cause substantial damage to boats and trailers.

For optimal performance and reliability, it is always recommended to chose Solid Plastic Bunks vs hollow bunks.

Bunks provide excellent hull support and are simple to maintain. Rollers make launching easier, especially on shallow ramps or for solo launching. Many boaters use a hybrid trailer setup with bunks at the stern for support and rollers up front for easier loading.
