SIMPLY RADICAL 

French WIND magazine likes the board for its “liveliness” and because it “offers radical rides in all types of conditions”. And British WINDSURF states that the “carving flow and response seem almost supernatural” and “in clean cross-offshore conditions, it was simply a revelation”!
Morgan Noireaux sailed a Radical Thruster Quad to win the only true down-the-line PWA wave event –the Aloha Classic– two years in a row.

The deep double concaves in the bottom are the distinguishing shape details of this design. Their deepest parts sit right under the straps creating long flat planing sections. Together with the wingers –which slightly widen the planing surface– these concaves enhance acceleration to a surprising speed. You’ll enjoy the lively and “light” feel based on the very short wetted planing area.

The Vee cushions the ride and creates a well rounded bottom curve at the rails. As a result, the board turns tight easily offering ultimate rail bite. It instantly responds to every little input from the rider. The inexperienced wave rider will consider the board’s speed of reaction as nervous, while the targeted, advanced wave rider will love this liveliness, just as much as he will adore the super fast change from rail to rail.

The Radical excels in side to side off-shore conditions and keeps getting better and better, the stronger the wind and the bigger the waves get. Its strength? Firstly, it is the feeling that there would be absolutely no limits for radical riding. And secondly, the excessive amount of speed it can carry into the bottom turn in total control, remaining all time ready to smoothly adjust the turn in order to hit the lip where wanted at maximum pace.

The boards come with the proven quad fin setup enhancing the grip and drive in fast wave carves.
The rear center fin box for a thruster setup can be used for more power in light or side shore conditions or for more control in real big waves – currently Jason Polakow’s favorite setup for big waves and Antoine Martin’s favorite setup for European PWA events.

>> According to our pro riders unmatched for real down-the-line wave riding! You’ll be blown away by your high speed carving top and bottom turns. The board provides all the needed grip, control and liveliness throughout your wave moves.
It rewards an active riding style with turns that you used to dream of. Every advanced waverider will simply love them as they take his riding to the next level.
Go and get radical!


The boards additionally come with plugs to cover all fin boxes.
PRO EDITION in S-Glass Technology with stringers and carbon rails.

The RADICAL THRUSTER QUADs, WAVE SLATEs and THRUSTER QUADs feature 5 fin boxes:

  • 3 Slot Boxes with 2 covers and
  • 2 side fin Mini Tuttle boxes with 2 covers
The boards are equipped with the fins which suit their character best. Still, you can acquire additional spare fins to trim the boards according your requirements or the given conditions. So, each board can be used in every possible setup: quad, thruster, twinser or even single-fin. To cover the same range of use, the main thruster- or the 2 twinser fins should be 2 cm bigger than the quad fins, and the single-fin should bigger again - minimum 2 but up to 5 cm.

Advantages of each setup:

SINGLE: "Drive", directional feel, good planing.

THRUSTER: The maneuverable version of the single fin setup with better control. The best on- to side-shore wave riding option overall.

QUAD: the best side-offshore down-the-line wave riding option overall

TWINSER: Livelier version to the quad setup.

LIMITED FINISH - LESS IS MORE

Since 2004 the first JP PRO Edition boards have a (SUPER) LIMITED FINISH. By reducing the amount of paint (sanding off) the weight is decreased. Consequently, the boards have a custom look with certain "imperfections" in the paint, thus the material below might shine through. Sometimes they even look as if repaired. This is also true for the Full Wood Sandwich boards as they now feature a LIMITED FINISH, too. You won't find two boards exactly the same. We believe this is worth it as the weight reduction is substantial and there's no loss of durability or strength.

STORAGE

Store your board in mild (neither hot, nor cold; not exposed to sunlight), dry places ! Winter storage: non-freezing (constantly above +5 C). Note: Avoid storage in closed, damp conditions like in a wet boardbag! So, after windsurfing and safe transport put the board out of its bag and let both dry separately - otherwise your board will suffer from osmosis and blisters (bubbles) will show up on the boards surface. And your bag might start to smell.

AIR VALVE

airvalveWe highly recommend to open the air valve screw when the board is not used. Reason: Due to high pressure differences the sandwich construction suffers from high stress and can delaminate long term from the board's core. This will result in a soft spot and start absorbing water. Pressure differences are caused by high temperature variations or other pressure variations from e.g. aero planes. Do not forget to close the air vent before going on the water!

NOSE PROTECTOR

UNI-Noseprotector-BLACK-neu02 Damages caused by impacts are not covered under JP-Australia's limited warranty. Therefore, JP-Australia highly recommends the use of a nose protector.

Especially recommended for novices and everybody, who wants to protect the board nose.

The universal protector: Made of EVA, the UNI NOSE PROTECTOR is a very light yet strong protection. It is easy to handle as it is simply glued onto the nose.

The set consists of 6 pieces: 2 side parts (one left and one right), and 4 connections in sizes Small, Medium, Large and "Wave Slate".

By combining the two sides with the appropriate connection at the front, noses of almost all standard board sizes and shapes can be covered efficiently.

This makes it an universal protector not only for JP boards but for most boards available on the market.
