 Kiteboat advantages


More Apparent wind

A kite is a sail that you can fly through the air or just park it in the air.  As you fly a kite, it is speeding up and will have lots of aparant wind!  Creating more power when you want to, how awsome is that! As sailors know it is all about apparant wind.  Using a flying sail or kite is the utmost example of  using apparant wind!

Less heeling momentum:

Masted sail boats have a central point of forces in their sails, some meters above the water. Therefore creating a higher/bigger  heeling momentum. (and we should not forget the pitching momenum forward)  A kite is generating order forces. A kite has a low heeling momentum as it is attached low on deck. So you can have more m2 sail when kiteboating, compared to masted sailing. Guess what is faster then.

How I came to this;

As being a sailor originally,  I took a kite lesson around somewhere 2011,  just because I wanted to know how it worked and felt.  After an hour I felt the huge extra power of a flying sail. So there is the point where I started kite sailing, an amazing new sailing sport. After several try outs on existing dinghies with more experienced kiters, it became clear that  kiteboating is totally different and needed her own hull. After a couple of protoypes and hours on the water, years later;  the plugs and moulds have been developed and constructed in 2015.

Hull Shape:

Because forces are totally different when sailing with a kite, a Kiteboat does need a wide planing surface on the aft and it requires less volume in the front below the waterline. Most masted dinghies are designed with a large volume in the front to cope with the pitching and a smaller planing surface on the aft. (laser, Finn joll, 470, etc)

It resulted in the most accessible kiteboat dinghy, a monohull off course because it is much more playfull, The Kitetender 400


Kitetender essentials;

  1. Depending on what kites you use you can achive boatspeeds over windspeed and beating therefore all other masted dinghies
  2. If an well experienced crew, you can go over 20knots of boatspeed
  3. You can manouvre better with the Kitetender then any other masted sailboats.
  4. You need  wind in order the kite stays in the air.

What skills are needed to Kitetender?

  • A bit of dinghy sailing would be an advantage. Sailing with a kite is like sailing a big gennaker, you have too much presure, go downwind, If you need pressure, go upwind.
  • Kitecontrol is a neccessary skill.  If you can fly a 4 or 5 depower kite on land and  you are confident with it, you can have a go.
  • Allways make sure you start in easy waters and with a small kite in moderate winds and circumstances to get to know kitesailing.
  • Be seated all times, have at least 1 foot in the footstraps, accelerations can be huge
  • Go out preferrable with the people who have Kitetender experience and teaching abilities, like the Kitetender Centers mentioned !

Pre cautions and more (active) safety issues are:

  • Crew competence is the most important safety issue onboard!
  • kite knowhow & control is essential, if you do not have it don’t go out!
  • Allways wear the standard safety releash fro JOBE, which is delivered with your kitetender.
  • Start slowly with a smaller kite and get used to kitesailing first. After some good sessions and confidence as a team you can build up performances and choose for more wind and or bigger kites.
  • For sailors!, beware of huge accelerations when the kitepilot is powering/flying the kite.
  • Allways be seated and hold tight. By powering the kite forces can be up to 8 times a normal static sail! (based upon standard line length 25 mtr)
  • Allways wear sufficient sailingclothes, wetsuits and rescue vests and a knife!
 If you do not have the know how as mentioned above, do take lessons first! Do not try it out first!
