What are the differences between a jib and a gennaker?

The Jib is a relatively flat, rugged headsail designed primarily for upwind performance. It optimizes laminar flow over the mainsail to maximize speed and pointing ability. The jib also makes tacking easier and provides precise control over the sail plan. The Gennaker is larger, has a deeper draft (more “belly”), and is made of lighter fabric than the jib. It provides a significant speed boost on reaching and downwind points of sail. The gennaker is best used in light to moderate winds.

Which is the better option: the Jib or the Gennaker?

It mainly depends on the sailing conditions and the sailor’s preference.

Generally, the jib is more versatile than the gennaker. The Jib Kit includes two cam cleats to be mounted on the forward wings for the jib sheets. Once the jib is set and the sheet is locked, the sailor has both hands free to manage the tiller and the mainsheet.

The jib adds nearly 28% more sail area compared to the unreefed mainsail. This provides a substantial power boost, especially in 10-12 knots of wind. Because of this extra power, the sailor needs to be very reactive to wind shifts. The Tiwal 3R Max will plane much faster with the jib.

The Gennaker is installed on the Tiwal 3R with blocks at the front and rear of the hiking wings. Gennaker sheet tension must be constantly adjusted by hand based on the wind and the boat’s heading. The gennaker is easier for a solo sailor to manage in light air.

Do I need to change the mast?

Yes, you must replace the three bottom sections of the mast. These new sections are structurally reinforced through their constant-section cylindrical shape and a specific carbon fiber layup. The original Tiwal 3R mast is not designed to support a headsail. The new bottom section includes a new mast protector, adapted bushings, and the necessary lashing blocks.

Can I use both the Jib AND the Gennaker while sailing solo?

The Jib and Gennaker options are designed to be installed together on the Tiwal 3R Max. They can be used separately or simultaneously. Using both headsails at once is best for light air or will require a high level of skill from the sailor! You’ve been warned…

How do I stow the headsails while on the water?

Simply pull the furling line, and the sail will roll up around itself. Both the jib and the gennaker are equipped with their own furler. A swivel at the head of each sail completes the furling system. You will need to install one cam cleat per headsail on the Tiwal 3R’s central frame along the daggerboard trunk. This requires drilling a new hole, which is a quick and easy DIY task.

Can I start by buying the Jib Kit and add the Gennaker later (or vice versa)?

Yes.

Do I need to replace my mainsail?

No, any Tiwal 3R mainsail model can be used with a headsail. You simply need to make a small cut in the sail sleeve with scissors and apply the provided self-adhesive Insignia patches to reinforce the edges.

How long does it take to rig the Tiwal 3R with one or two headsails?

The assembly process is quite straightforward.

The Arm Adapter is a one-time installation on the central frame. The furler remains permanently attached to the jib boom. To set up the jib, click the jib boom into the adapter and secure it to the hull using a line attached to the towing ring via a Clamcleat. Before stepping the mast, pass the jib halyard through the block at the top of the mast. Once the mast and mainsail are in place, clip the jib’s tack to the end of the jib arm. Attach the jib to its halyard, hoist it, and lock the halyard into its Clamcleat. Finally, install the jib sheets and run the furling line through its dedicated cleat along the daggerboard trunk. This process should take 5 to 10 minutes. The procedure for the gennaker is very similar.

Does adding a headsail change the boat’s balance?

Adding a jib changes the boat’s initial longitudinal balance, mainly because it is used for upwind sailing. This shift in balance is compensated for by the sailor sitting slightly further aft. This new position also helps keep the bow out of the water and reduces the risk of “pitch-poling” or stuffing the nose in wavy conditions.
