How did the 1030 come to be?
by JP Kelbert

The hull of the JPK 1030 was born on the return from the 2018 Transquadra, after my second place on the JPK 1080 against the Beepox 990 skippered by Alex Ozon.

On the one hand, a boat of 10 meters by 3 wide and 2.5 t of displacement, on the other hand a boat of 10.80 meters by 3.50 wide for 4.8t.

As 90% of the Transquadra is sailed downwind, a good VMG boat is of course ideal for winning. From this point of view, the Beepox was the perfect boat to plan early and to keep high averages above 18-20 knots, which was the case on the first and second leg of this edition. Obviously, this very typical boat is not very efficient upwind (especially in breeze) and cruelly lacks power on certain courses.

From this observation, I asked Jacques Valer to design a boat capable of planing a bit earlier than a JPK 1010 (4 times winner of the Transquadra) or a JPK 1080, but also of gaining power on the reaching, while remaining efficient upwind.
Here again, Jacques' work was not easy; several versions were made, including a very "scow" version, which was judged too typical. The rating increases very quickly when the boat is lightened or powered, so there is very little margin for manoeuvre in order to maintain versatility and save the rating in most conditions... especially when faced with boats such as the JPK 1010, which is ultra-versatile and has an interesting age allegiance!

The JPK 1030 is therefore relatively narrow, with very full forward sections and a smaller hull cavity for a more tensioned hull slope. When heeling, the hull is also well tensioned to favour heeled boat planning.

On the water, the boat is exactly where we expected it to be, super efficient on the reach, planing, but also very efficient upwind from 10 knots of wind, when below this threshold you have to accept to increase the rating by an extra surface in light airs.
The results over two seasons speak for themselves and there is still plenty of room for improvement, particularly in terms of sail configuration and design.


Construction
Made of Airex / glass / vynilester sandwich, the deck, hull and all accommodation structures are made under vacuum by infusion.
The draping plan and the choice of the different layers of fabric make it possible to optimise the weight, with substantial reinforcements in the areas subject to stress and very light structures at the top of the shell and on the deck.

Keel
Lead
Built in keel sole with garboard coverings
Fixings in the timber floor structure

Rudder head
Double rudder under counter
Sandwich construction + unidirectional fiberglass + stainless Steel rudder axle

Main tiller
Carbon type
Telescopic tiller

New vinyl hull wrap added 2023 - Grey and red. Original hull is white underneath.
