ALMOST EVERY BOAT IS DIFFERENT
External fixings (or plates) are the visible plates that are fitted onto the outside of the Collar. These plates add extra strength as they squeeze the Collar towards the boat and reinforce the foam. They're also needed if internal access is not available.
External fixings is what helps make Kapten Boat Collars so versatile, that they can be fitted to suit a wide range of different boats.
All the hardware you need, such as extra long drill bit series, are provided in your kit.
SIZES OF BOATS AND THEIR FIXINGS
2 External fixings per side, at seats.
These fixings have the long external screws go through the foam and anchor into the hull, where each seat is placed.
The screw heads are concealed under the seats, and nylon dome washers can be fitted for extra protection. These fixings don't need to be pre-drilled, so the hold is very tight on the screw.
PROVIDED: 4mm x 100mm x 150mm aluminium plates that are shaped, painted and countersunk with 150mm stainless steel bugle batten screws, hex head driver bit and nylon dome washers.
$10 per fixing.
4 External fixings per side, evenly spaced.
If there's 1-2 bench seats, then 1-2 of the fixings go into the seats, as above, but for these biggerr/heavier boats, an internal plate is needed for the 150mm screw to pass through. If there's no bench seats, all external fixings will be anchored into the internal plates, with shorter 120mm bugle batten screws.
4mm x 100mm x 150mm aluminium plates (shaped, painted and countersunk), 150mm stainless steel bugle batten screws, hex head driver bit.
If you have bench seats, we'll also supply nylon dome washers and a 6.5mm extra long drill bit series for the guide hole through the internal plate.
For the other fixings we supply 5mm long series drill bit to pre-drill the internal plate. We also supply an extra screw to be used as a guide screw to start the thread on the fixing.
$10 per fixing.
BOATS OVER 4.5M
External fixings spaced 600mm apart
Most boats over 4.5m have larger engines, venture further abroad and in rougher conditions and carry a heavier load - such as internal structures like forward windscreens and decks.
Therefore, we increase the amount of fixings to be approximately every 2nd internal plate, or every 600mm, starting from the transom end.
This even, continued pressure applied to the outside of the Collar, strengthens the foam a lot. Fixings are like the ones shown previously/above.
$10 per fixing.
2.4m BC Shields +single fixings
The BC Shield is an option for those who wish to protect their Collars from crab pots etc, but is also an alternative to flat bar (see below) on smaller boats as it encases the Collar and therefore strengthens it a lot.
BC Shields are made from 3mm pressed aluminium and include several stainless steel bugle batten screws per side.
For boats over 4.25m, a pair of 2.4m long BC Shields: $358 inc GST (or $179 ea).
For a smaller pair of BC Shileds, at 1.2m long: $198 inc GST (or $99 ea).
FLAT BAR FOR BIG, HEAVY BOATS
As flat bar can't bend and twist like the Collar can, it can only be used down the rear, straighter sides of the boat. Single external fixings are required at the bow. These are spaced and allocated to be fitted every 300mm.
Flat bar, 4mm x 100mm + single fixings
Usually for boats 5m +, the use of aluminium flat bar requires every internal plate to have an external screw, so for a boat to have this many fixings, it is reserved for larger, heavier &/or faster travelling boats.
4mm x 100mm Flat bar, to the length you need. Flat bar is roughed up and painted (so paint adheres to it), and not countersunk - as the internal plate positions will vary boat to boat. Enough stainless steel bugle batten screws will be provided for a fixing every 300mm. Hex head driver bit & the necessary long series drill bits are also provided.
You also require 2 or more single external fixings per side at the bow area, 4mm x 100mm x 150mm & the corresponding screws and hardware that they need to be fitted.
4mm x 100mm flat bar kit = $160 for both sides.
4mm x 100mm x 150mm single external fixings = $10 ea
Flat bar; 6mm x 125mm + single fixings
Wider and thicker flat bar offers greater strength and coverage for larger &/or heavier boats.
Due to the weight of the flat bar, this upgrade in flat bar is reserved for bigger boats at least 5m long.
6mm x 125mm flat bar kit = $220 for both sides.
6mm x 125mm x 150mm single external fixings = $14 ea
Flat bar; 6mm x 160mm + single fixings
The largest and strongest external fixing provided.
The 160mm high flat bar covers most of the 240mm face of the Collar, applying optimum, even pressure distribution.
Due to the weight of this flat bar, it is reserved for very strong & heavy boats.
This external fixing is required with the Chemi-Weld fitting method (see Fitting page for more info).
6mm x 160mm flat bar kit = $280 for both sides.
6mm x 160mm x 200mm single external fixings = $16 ea
TUFF-TEC FOAM IS TOUGH INDEED
The inner and outer harder layers help disperse the pressure applied to the Collar from the external fixings.
