Below: click to see your style of boat with a KBC.
Don't like the idea of screws? See if your boat qualifies for the Chemi-Weld fitting method instead.
WHICH FITTING METHOD SUITS YOU?
1. CHEMI-WELD METHOD
Fixed from the outside
- Some aluminium boats (must be large enough boat to handle the extra weight of the external fixings).
- Fibreglass & timber boats (under 4m, with less than 15hp).
- Great for large plate & fibreglass boats with limited internal access (such as high floors, double skinned etc).
Small fibreglass boats can have the Collar simply glued on with super strong T-Rex Power: Fast Grab adhesive with no external fixings required.
For Max size Collars only, adhered to the hull with box-sections (glued or welded to the hull) & large flat bar & external fixings.
More expensive but strongest fitting method. No internal/screw fixings required.
2. MECHANICAL (common) METHOD
Cheaper & easier to fit
- all vessels with good internal access & single skin hulls. e.g.;
- plastic boats
- fibreglass boats
- Aluminium boat

FITTED IN 5 BASIC STEPS
STEP 1 - mark and drill your boat
- Mark fixing points every 300mm inside your hull, using your supplied template as a guide.
- Drill where you've designated the screws to fix.
STEP 2 - strap Collar to your boat and mark the Collar.
- Strap the Collar into the correct position.
- Mark the Collar by stabbing it with a thinner drill bit through the fixing holes (indicates where the internal plate needs to go).
STEP 3 - remove Collar and hammer in plates
- Remove Collar from your boat and place it upside down on the ground.
- Line up plates above your "poked" marks and hammer them in alongside the inner hard layer (only available with Tuff-Tec Collars).
- (if Original Collar)- cut each pocket with a long knife.
STEP 4 - glue the plates inside your Collar
- Squeeze 1-2 pumps of Liquid Nails Original into each plate pocket & to seal openings.
- Set aside in the shade and allow glue to thoroughly dry (4 - 5 days).
STEP 5 - strap Collar to boat and fit it off.
- Strap the Collar to the side of your boat again, in the same position as last time.
- Apply Tef Gel to the screw tips and under the dome washers for non-corrosive and water-repelling properties.
- Fix the Collar to your boat by tightening the screws into the plates inside your Collar, from the inside of your boat.
- *boats over 3.6m > apply a bead-line of T-Rex Power: Fast Grab adhesive to the underneath.
- Now you've got that BIG BOAT stability.

FREQUENTLY ASKED QUESTIONS
Liquid Nails is the only one we recommend or cover with warranty as it chemically bonds to the foam - (think melting together with the foam) - so the foam actually tears before the glue will ever let go - and it takes a LOT for the foam to tear.
Sikaflex on the other hand will stick to the Collar, but under pressure it will peel off the Collar, leaving an almost perfect impression of the foam on its surface.
Therefore, only Liquid Nails Original (or its brother, Parfix), should be used to glue in the internal plates.
The full-length is a major feature that makes KBCs work as well as they do. #1. It turns down the spray, for dry rides. #.2 It produces bow lift, to protect against nose-diving. #3. It provides maximum overall buoyancy.#4. IMPORTANT: if a Collar stops short (is not full length) on a chine fitting, 'green' water can get on top of it during a turn, which has the potential to make it dig in and flip the boat. A proper-length Collar does the opposite, allowing the tightest, most level turns possible.
No, because all screws are coated with Tef-gel, an amazing creamy substance that remains tacky for years, to keep a protective barrier between the stainless steel screws & your aluminium hull.
The Collar itself is fitted tight against your hull and is non-corrosive, being foam. If you use your boat up very dirty creeks or flood waters, and are concerned about debris wedging against your hull, you can run a strip/bead of Sikaflex or silicon around the Collar to seal it, if you want.
Regarding painted boats; factory painted or boats that have been prepped and painted with quality marine paint, won't have a problem with a Boat Collar being fitted. BUT, if you have a hull that's painted cheaply, like with house paint, that was also poorly prepared, it's almost guaranteed the paint will deteriorate and allow water to sit behind the paint and cause corrosion.
Yes, absolutely. Most Collars will fit underneath side pockets, but if the side pocket covers the fixing area, a small pilot hole is required to be drilled through the side pocket (about 12mm diameter). This allows for the long drill bits to pass through, allowing you the right angle etc on the screw heads.
You'll only have to lift your main floor if the floor is 40mm or more above the chine line (side plate meets bottom plate). Most tinnies have the floor sitting just above the chine bar, so doesn't need removing.
If your floor is sealed and/or can't be removed, and is higher than 40mm - you can either;
- Raise the Collar so the bottom fixing sits just above your floor.
- Use external fixings to anchor the Collar below your floor.
- Or, you may be eligible for the new Chemi-Weld fitting method (only suitable for large boats) that requires no internal fixings. Ask us for more info.
If your boat is over 4.5m long and have either pressed or flat sides, and is either fibreglass or aluminium - yes, you may be able to glue it or weld it onto the sides of your boat, using our new Chemi-Weld fitting method. Ask us for more info.
