Hot Air Seam Welding
Hot air rotary heat-sealing is a welding process used to join thermoplastic industrial fabrics and films using very precise heat, speed and pressure settings. The correct combination of these three parameters allows for the achievement of a complete weld. In the case of hot air, heat is provided by blowing compressed air across electrical heat elements and is injected at the welding point. The tightly controlled temperature can range from
40°C to 750°C.

Optional Extras
Race Carbon Fibre / Kevlar floor boards
Custom fitted to your hull for a perfect fit $1200.00 Inc GST.

Benefits
Strength - The Carbon / Kevlar blend is used for its
strength for the compression and tension forcers that your hull
withstands under the tougher condition.
Hull Rigidity - A very noticeable difference in hull
twist even in a strait line which translates to speed. (Simple
test is to support the standard boards upright between your feet
and twist with your hands “approximately 110mm of twist per board
x 2 =220mm of hull twist).
Weight – Carbon / Kevlar boards weigh approximately ½
the weight of the conventional marine ply boards (increases your
overall acceleration “power to weight”).
Save $$$ and Time – Carbon / Kevlar boards virtually
eliminate the replacement cost of broken boards and down time of
replacement which happens to most marine ply boards.
Carbon Fibre nose cone (Aquarius only)
Custom order with new hull only - $750.00 Inc GST extra.
Benefits
Strength - The Carbon Fibre is used for its strength

weight of fibreglass saving you another 5 kilograms (increases
your overall acceleration “power to weight”).
Looks – “WOW” just look at the Carbon Fibre finished
off to perfection with large weave matting. A perfect option for
the enthusiast.
