CoverQuest.com has already applied Bimini's to many year, make, and models of boats eliminating the need for measuring! We recommend certain size tops guaranteed to fit your specific year, make, and model.

For the boats we have yet to recommend a specific size for, or for the customer who wishes to choose their own dimensions - tops are offered in a range of heights, lengths, and widths to offer the best fit for your boat. Shop Now by Your Custom Dimensions!

If you need to measure for your new boat top, the first thing to consider is what portion of the boat you wish to cover. Keep in mind that the top's mounting point will be the center point of coverage. For Example, a 6' top will have 3' of coverage in front of the mounting point and 3' behind the mounting point. Top lengths will be different for every boat, depending on your use and preference. A 6’ long (3 bow) top is standard for most runabout and center console boats, but if you have a smaller ski boat you may want something in the 5’6” (2 bow) length. Pontoons will require a much larger top, this is where the 8’ (4 bow) top is typically applied.  Once you have decided your points of coverage and length, you will need to find your mounting width.

To find the mounting width, measure across the boat at the center point of your coverage area. This point will also be the center point of your top (example: If you select a 6’ top you will have 3’ of coverage in front of and behind the point where you are measuring from). CoverQuest Bimini's can be mounted to virtually any surface from the windshield, to a railing, and of course the standard gunnel application. Once the mounting width is determined, measure from that same mounting point up to a height that is comfortable for you to stand, sit, or fish under. Keep in mind that the higher you go, the more shade you lose. Our advice is to stay as low as possible. This will not only give you better sun protection, but will maintain the sleek, low profile look of your boat. You should now have the length, width, and height needed to select your new top!

Laying Points 

When you lay your top down, either forward or backward, the top actually becomes longer. This is the result of the top's bows nestling together. This measurement can be important when you have equipment and other items to consider. Please refer to the chart below for each top's “laying length”.

3 Bow Top's

1. Lay the canvas out on a flat, clean area, with the bottom side up. Sewn-in label indicates the bottom, or inside, and the back of the top.
2. Identify the hook shaped, long, medium, and short bow side frame parts. Using the long bow side frame parts, and one of the center bow frame parts, assemble the side bow and center bow parts as shown, aligning the pre-drilled holes. Use the 1/2”, no. 8 screws to connect the bow parts securely.
3. Repeat this procedure for the medium and short bows, aligning the pre-drilled holes and securing them with 1/2”, no. 8 screws.  Caution: If screw heads become burred, cover heads with duct tape to avoid damage to canvas.
4. With bows assembled, first pass medium bow assembly through sleeve in front of top.  (This is the sleeve opposite the end with the sewn-in tag.) Note the position of the single pre-drilled holes on the bow frame.  (Holes should be facing in.)
5. Pass the short bow assembly through the small sleeve in the center of the top and the long bow assembly through the sleeve at the back of the top. Again note the position of the single pre-drilled holes on the long bow frame. (Holes should be facing in.)
6. Pass the buckled end of the adjuster strap through opening in fabric and around long bow. Thread looped end through buckle. Pass the looped end of the strap over the end of the short bow and slide down into position directly across from opening in fabric where buckled end is attached. Leave at maximum length.  Repeat this step for the second strap.
7. Pass looped end of each hold down strap over each end of the long and medium bows. Use a no. 8, 1/2” screw to fasten strap to bow frame at each pre-drilled hole position as shown. Position strap over hole and insert screw, with finish washer, through center of strap and into pre-drilled hole.
8. Connect short frame ends to jaw slides on each side of long bow frame.  Repeat for medium frame ends, jaw slides should allow short bows to pivot, but be tight enough to hold securely.

Installing your Bimini Top on your Boat

1. The top is now ready to be inverted and positioned on the boat. This is easier with two or more people, one to hold the top in place, while another marks the positions of the hinges to be attached to the gunnel of the boat.
2. Measure the marked position of the hinges carefully to make sure they are exactly opposite each other. If not aligned properly, the top may become warped or damaged and unstable while in use, or look unbalanced.
3. Use a drill with a 9/64” bit to drill the pilot holes for the deck hinges.  If drilling into fiberglass, hollow out the pilot hole to avoid cracking fiberglass when installing the screws. Secure the deck hinges with 1”, no. 10 sheet metal screws provided.
4. Place top on boat, attaching the long bow ends to the hinges securely. raise top to desired upright position and adjust each hold-down strap. Straps should be adjusted to a length that attaches to the boat at approximately 45º to 60º angles to hold the top securely to boat.
5. Mark the position of the eye straps on the gunnel of the boat, measuring to make sure they are exactly opposite each other on the sides of the boat. Use a drill with a 9/64” bit to drill the pilot holes for the eye straps. Be sure to hollow out the pilot holes with the drill bit if drilling into fiberglass. Secure the eye straps with 1”, no. 10 sheet metal screws provided.
6. Attach the snap hook to the eye straps and adjust the hold down straps.
7. Desired crown on Bimini can be achieved using adjuster straps after installation is complete.

Please Note: The process of assembling the bimini frame may cause the width of the frame to expand or retract at the mounting points. If the frame appears too wide or too narrow when you are ready to mount the top on the boat, simply mount one side and, with minimal force, push or pull the opposite side to fit the mounting point on the gunwale.  Important note to Top Installer/User: Be sure all set screws, fittings and pre-installed hardware are tight.

We also offer Fully Assembled Bimini Tops!

Using Quick Release Pins

Quick Release Pins allow you to easily detach your top from the mounting brackets. These are a necessity for boaters that remove their Tops after each excursion. Please see the directions below on how to install your quick release pins:

First remove the bolt from the deck hinge. Drill out the bolt hole with ¼” drill bit. Place tab on cable underneath deck hinge –secure with 1” – no. 10 screw.

Place the outside eye end of top or brace kit in deck hinge. Push pin in hole until metal ball passes through to keep the pin in place.

Thru-Bolting

To prevent the possibility of personal injury or damage to your boat do not exceed 35 MPH with your top deployed without thru-bolting. Be aware of wind speeds and reduce speed accordingly when wind is present. Lower and secure your top when trailering.

If you need to travel at a speed higher than 35 MPH you may thru-bolt your top. We do not recommend traveling at speeds higher than 45 MPH in this case.

• Use Stainless Steel fittings, for added strength.
• Thru-bolt the eye straps and the deck hinges. You will need a longer bolt that will go through the fiberglass and extend to the underside. You can then add a washer and nut for extra security. This is necessary because of the friction from the wind. This friction causes the screw to wear at the fiberglass resulting in the Bimini coming loose.
• Check the angle of the top. The front of the top should be angled down, to do this pull the front hold down straps tight.
• Check all straps and fittings for tightness before use.

Cutting Down your Bimini's Frame

The following size tops can be shortened in height by the recommended measurements below. All other tops can be shortened up to the first jaw slide.

• 35” High- Up to 5”
• 46”High- Up to 10”

If you wish to shorten the height of your top you may do so by cutting the desired length from the ends of the long bow using a hacksaw. Note: Do not shorten past the first jaw slide. Once the top has been shortened, use a 9/64” drill bit to carefully drill the hole for the rivet. Be sure the eye end is set in the correct position before you drill for the rivet. Use a rivet gun to set the rivet in place.

Additional Hardware Includes:

• 2- 3/16” Rivets
• 2- 7/8” Outside Eye Ends

*DO NOT attempt to cut any more length than what is recommended.

*DO NOT attempt to alter the short or medium bows.

 

Protect your investment by following our Bimini Top Care Tips:

• Check all screws and fittings regularly and tighten as needed.
• Make sure hold down straps are tightened.
• When trailering, fold down your top and stow in the Storage Boot.
• We do not recommend exceeding 35 MPH with the top deployed without thru-bolting your top.
• Keep your top looking its best by regularly brushing away any loose dirt or debris with a soft brush, then rinse with lukewarm water.
• Clean your top as necessary using a solution of lukewarm water and a mild soap such as Ivory. Rinse thoroughly and allow to air dry. 
• Always allow top to dry thoroughly before folding for storage.
• We highly recommend 303 Fabric & Vinyl Cleaner which is safe and effective. Be aware that repeated cleanings can diminish the water repellency of certain marine canvas. Apply 303 High Tech Fabric Guard to restore water repellency to factory-new levels.
