good shit mate

This is really one of your simplest and best additions that should be added to all Kayaks

Nice movie. However you can make it yourself. Just google woodprix and learn how to do it easily.

This time I'll use woodprix instructions to make it by myself.

I think it is shock cord

I love that you demonstrate these techniques in choppy water. It's really useful to see it in the sorts of conditions you're more likely to need them in, rather than a calm millpond. :D

Genial vìdeo !! Super didàctico y ùtil !!

This is really one of your simplest and best additions that should be added to all Kayaks.
I agree with david below, the added Bungee would be a welcome modification.

Do you not include a short length of shockcord heavy duty in your tow line? I find that when towing in heavy seas that the occasional backwards tug you get whether it be attached to your kayak deck or waist when your kayak is on the front of a wave as the one being towed rides off the back of the crest can sometimes have a stopping effect deadening effects tomforwards motion the inclusion of a heavy duty bungy cord allows both kayaks extra play in stretch of tow line absorbing any conteadictory movements ie you going faster forward whilst those being towed are holding riding off the crests moving back as you are trying to go forwards at even speeds i find this type of towline auto absorbs the negative drag or energy as you try to do your thing in towing
Automatically reducing the level of hard if attached to your waistline gut wrenching jolts you can get in heavy following seas
Its only a very simple addition to existing no stretch cordline but makes your tow line infinitely more comfortable to the gen feel also tends to go easier on the decklines i like to attach mine to a deck cleat reinforced from underneath as decklines arent always strong enough to absorb the powerful forces involved in boisterous or contradicting water
Flow and patterns whilst towing
The type of bungee cord is hard skinned type not type you get for roof racks you bind another cord around twist it around bungee making it stiffer than just using one core width you double it up bind it then work it into your static cord tow line by 8-9inches in length the static line takes the weight the bungee the stretch between wave tops
Makes up the difference!
Saves leaving your guts behind for the sharks or having bellyache after you get back home if youve had misfortune to be an instructor and been towing kids along on your waistline allday
As theres only so much of that anyone can take including anyone with a sixpack
The reinforced deckcleat to rear of cockpit is good point acts as fulcrum balance point on kayak two is better either sides as can alter sides i also attach several points incl tip tails near toggles for other kayakers to sidle alongsides n fix too without any needs for my direct involvement in attaching use a clever clip that when pulled from cockpit releas

interested in making a contact tow line.  what did u use to close off end of the cordage?  looks like red tape in the vid? ty karen
