This article on how to make a kontiki has been submitted by Grant Kirby. Grant.Kirby@telecom.co.nz and we must thank him for sharing his information with all anglers.
For those who are unsure what a Kontiki does, it is used by beach anglers to tow a long line with multiple hooks on far out to sea where the sail drops down after a predertimend time and the long line is left to fish for whatever. It is then wound or pulled back in and all the fish are removed!!!!
There are plenty of designs that work, consisting from using a large rubbish bag to Kontiki’s with hollow PVC pontoons.
One basic design consisted of a wooden H shape, which are attached lengths/blocks of polystyrene on the bottom of the sides of the H to form 2 pontoons. These are obtained from old packaging inside boxes etc. from TV’s, Appliances etc..
Sail - A small rectangular sail is framed with typically wood, and placed so that when you look at a plan view ofthe H it sat across the bar of the H. This is hinged to the H at each side so that when retrieving the Kontiki thesail drops forward so you do not have the extra wind resistance of a solid sail design.
Setting up the sail - To get the hinge to drop down once the Kontiki was launched, a suggestion is to run say two lines from the top corners of the sail frame. (Drill a small hole in the rear of each pontoon large enough to thread your line through but small so the “lolly” does not pass through) When launching raise the sail into the vertical position and thread both lines through each respective hole. Tie on a barley sugar/lifesaver to each thread at the bottom of each pontoon. The idea is that once the Kontiki has been set, the “lolly” gradually dissipates in the water and once both lollies have dissipated the 2 lines are free and travel up through each hole allowing the sail to drop. Using two lollies ensures that the Kontiki gets out before a premature release.
Attaching the Kontiki - As for attaching the mainline line, you can run a short line off the back of each "pontoon" to a decent snap forming a Y to which the mainline can be connected at the bottom of the Y.
With this arrangement these short lines can be adjusted so that you could get the Kontiki to sail at an angle to the wind.
Attaching traces to the mainline – Proper Clips can be a bit costly, and an idea is to get lengths of suitable wireand bend into a shape as such.
Start by bending the bottom curve then the two corner curves, each end should now be lying parallel to each other. Bend these around a central point to create the bit sticking up. Allow say 20mm so for the mainline to loop over.
Attach your trace to the bottom of the clip, and to attach to the mainline just pass the mainline through the centre an up and over the short vertical.
