100mm D x 160mm H
Tuff-tec Mini 33
The most popular choice for boats 2.5m - 3m. The Mini 33 has half the volume of displacement than the larger Max 66.
100mm D x 160mm H
Tuff-tec Max 66
No.1 popular choice across the board. Offers the most amount of buoyancy, stability, and performance benefits.
140mm D x 240mm H

100mm D x 240mm H
The 2 types of Collars are the Original & the Tuff-tec. The major difference is Tuff-tec Collars have 2 harder/denser layers of foam compared to being 100% soft foam.
The harder layers on the Tuff-tec Collars are the outer layer, to cop all the bruises and scrapes, and the 4th inner layer, which makes the installation process so much easier.
The Collar names being; 33, 48, 66, are so called due to the amount of water they displace, per paired metre of Collar. In other words, a paired metre of Max Collar displaces 66kgs of water. Therefore, on a 3.5m boat; 3.5m x 66 = 231kgs of displacement from the Collars.
CLOSE-UP OF TUFF-TEC FOAM
Polyethylene foam; marine grade, closed-cell & crossed-linked
Quality marine grade Polyethylene foam is UV stabilised, petro-chemical resistant and has fire retardant added.
FEATURES OF TUFF-TEC KAPTEN BOAT COLLARS
Quality marine buoyancy foam
All our Collars are 100% closed-cell, cross-linked, polyethylene foam, so they do not absorb water and are non-deflatable, petro-chemical resistant and fire retardant.
Two layers of harder foam
The denser outer layer is for tough wear and a firmer surface for the external fixings. The inner layer makes fitting faster and easier and also strengthens the overall fitting.
The UV properties of our Tuff-Tec foam increases the lifespan of the foam by slowing the sun's deteriorating effects.

FREQUENTLY ASKED QUESTIONS
Weight of the Collar varies with the length of the Boat Collar and the amount of External Fixings required.
2.5m boats - 3.5m boats = 5 - 8kgs total weight added.
2.5m boats - 3.5m boats = 8 - 10kgs total weight added approx.
3.5m boats - 4.5m boats = 10 - 15kgs total weight added approx.
4.5m boats - 5m boats = 15 - 20kgs total weight added approx.
Our smallest kit size is the Mini 33, and the smallest length we do is 2.5m or 8ft 25".
No. There's no need to send several overall boat measurements - just one. We use your boat's centreline measurement - the same one that you use to register the length of your boat.
We then send you an extra 30-40cm (1ft) to allow for the curve in the boat and so you'll have offcuts. The amount of offcut varies on the boat shape, but you will have some.
For V-nose & flat nose punts, where the Collar is only fitted to the straight sides, we take 30-50cm off the centre line measurement, but you'll still have some off-cut at the back.
Prices are in AUD and include GST (delete 10% if outside Australia). Postage and fitting is not included here.

Most boats over 3m - 3.5m also require external fixings for additional reinforcement. How many and what strength your boat requires will depend on the boat, the outboard weight, the speed you travel and the conditions the boat is used in. These fixings start at $10ea. We'll discuss your boat with you to determine how many & the strength you'll need.

Is your boat one of these? Here's what you should to know
Boats over 3.5m
External fixings/plates. If your boat is over 3.5 metres and is not a tender, your Collar will need external reinforcement (minimum 1 per side).
Start at $10 each including GST and all necessary hardware.
Over 5m? All boat's over 5m are not covered with manufacturers warranty, so if any repairs are needed to be done, they're at retail price. We require photos and detailed description of large boats to make sure the fixings are suitable and extra strong.
Extra protection for your investment
Strap Protectors are custom made for your roof-topper &/or trailer boat.
The plate protectors help disperse the pressure placed on the Collars by your straps. Hence they prevent unsightly indents on the Collars and undue stress.
$79 per pair for Max & Slim Collars, including GST.
$69 per pair for Mini Collars, including GST
BC Shields are perfect for that tough-as-nails protection against crab / cray pots, oyster covered pylons etc.

$179 ea for 2.4m L, including GST.
$99 ea for 1.2m L, including GST. (pictured)
MORE FREQUENTLY ASKED QUESTIONS
All our Collars come in aluminium grey. Slight variances of grey depths appear throughout the stock, and even within the Collar itself.
However, the Collars can be painted or coated, if you really want the Collar to match your boats colour - see our Maintenance page for all the info you need.
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.
We take all precaution to avoid corrosion between the dissimilar metals of the tnnie hull & screws. All screws are coated with Tef-gel, an amazing, non-toxic cream 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, the paint will deteriorate over the years and will allow water to sit behind the paint and possibly cause corrosion.
Our advice is to frequently wash the Collar down with fresh water, and get the hose down the front of the Collar to wash any water out that's sitting behind it. You can slacken off on the fixings to give it a thorough clean and let the hull breathe & dry out, as often as you see fit.
No, for quality control, all sales go through the Nambour office in Queensland, Australia.
KBCs are great on V-nose punts, most fibreglass & plastic hulls, open single-skin canoes & kayaks, flat-nose punts, and of course the standard tinnie.
Double-skinned fibreglass hulls & big plate boats over 5m have the option of a different type of fitting, we call the Chemi-Weld method. Ask us for more info.
RIBs, jet skis & ski boats, inboard jet boats (including most bass boats) are not suitable for the Collars.
