Daggerboards are high aspect for maximum upwind pointing ability.
Angled at 5deg outboard, they are raised and lowered manually via a simple
Rudders also raise and lower manually via a rudder/quadrant design.
They are high aspect and offer perfect helm feedback due to the large wheel
and quadrant set up.
Overall the TAG 50 is designed for high sailing performance and
enjoyment and this feature should not be overlooked.
5.0 Deck layout
Starting in the bow, the TAG 50 has a removable 1.5m bowsprit tip. This is so you
can reduce the vessel length to an all-important 15m (49’3″) this allows you to
moor it within a 15m berth. The carbon bowsprit end is a tapered socket design
with a single pin and no stays, so very easy to remove and insert when you need
The Code Zero/Gennaker furling unit line is lead to the aft cockpit, so no one
has to go forward to furl these sails. The self-tacking headsail is also lead aft to the
The anchor system is built within the bowsprit and the chain and anchor winch
is located aft by the main cabin to move this weight as close to the vessel centre of
gravity as possible. There is a hatch to access the winch and chain storage. All very
neat and easy to operate.
The trampolines each have a solid tramp material at the cabin/foredeck
juncture to help restrict spray when traveling at speed. The tramp is attached to the
hull/cabin with a boltrope and is tensioned only on the forward and inboard edges.
All deck hatches are flush Lewmar hatches with built in moulded drains. The
main cabin windows are moulded and flush fitted also. The centre window is fully
opening and features a large moulded drain system and double seals for 100%
watertightness. Each side of the hatch are a set of steps cleverly moulded into the
cabin giving easy steps to the mast area.
The mast area has a self-tacking jib track and notably a rebated central area of
the cabin, which does a few things. It gives a good foot hold if working around the
boom area, directs all rain water from the rig – forward and down to the large
drains which could optionally be set up with a scupper/valve to direct fresh water to
the tanks. The rebated area can also be set up with an array of flexible solar panels
for trickle charging the batteries.
The mast has two winches mounted on the side. One is for halyards and the
other for reefing lines. The boom is low and easy to reach when reefing also. The
mainsheet track is located on the cabin-top where it is safe and effective.
6.0 Sailing cockpits
The vessel is set up with two sailing cockpits and sailing controls led to both
sides. The helm position and crew can reach the mainsheet traveller, mainsheet and
jib sheet with ease. The headsail furling lines are also aft. In effect you can sail the
vessel single-handed. Under the winches is a large rope locker so all sheet tails etc.
can be stowed safely and tidily out of the way.
The TAG 50 has a created a large useable area aft by not having the more
traditional built in steps. By building in the passerelle and swim ladder, we have
extended the cockpit useable area and kept it all on one level.
The helm has a side seat so you can comfortably perch yourself here
and have a very secure and comfortable place to sail from “keelboat style”.
The 1m wheel /large quadrant gives excellent feedback and a waterproof
chart plotter is built into the carbon pedestal with engine controls rebated
outboard and engine starting panels under the seat.
The helm position is ideal for looking at sail trim, steering through waves
and as it’s a long way aft, the bow spray misses this area (and even more so
with the unique wing design built into the hull topsides). Manoeuvring the
vessel couldn’t be easier as you are aft and can see both sterns and directly
down the topside. This compares favourably to amidships/forward single
One of the great features of this design is that you can enjoy sailing with
friends being part of the action. The outboard settee is very sociable yet well
protected from spray and wind. It really is an ideal arrangement. Such a
great place to sit and enjoy sailing.
Under each settee is a moulded locker for storage of rods, snorkel gear
and a variety of uses including an optional drinks fridge or icebox. The seat
backs/seat/upholstery are one item that hinges at the top edge making it
quick and easy to access the locker.
Forward in the cockpit and each side at the cabin end are two large
utility lockers for storing cleaning equipment, hanging wet coats and other
daily use items. Under the locker is a large opening port for the guest cabin
The engine room access hatch is built into the cockpit sole and is a
large hatch so lots of air and light can enter this area when working there.
Directly inboard is an easy access ladder and note that the engine can be
removed through this hatch if needed.
The foredeck is reached with two easy steps. The pulpit is located here
and gives a strong handhold going forward. Also in this area each side is the
filler for fuel. Note that the water filler is further forward to avoid confusion/
spillage issues etc. The mid- ship springs cleat is also located in this area.
7.0 Main living areas
To understand this layout it’s important to note that the cockpit and
saloon areas combine into this massive living area. We recognised that most
of the time spent on- board is in nice anchorages and warm climates. In this
regard there is no better layout than the TAG 50.
The full beam of the vessel is used to good effect with the outboard
cockpits. The central seated area is always fully shaded and the outboard
cockpits can be left exposed or optionally you can add simple sunshades to
cover this area that can even be left up while sailing…
Visually and one of the TAG 50s biggest features is the immense feeling
of space this innovation offers. The cabin fully opened is simply stunning and
unlike any other vessel. The side panels slide forward, the twin rear windows
drop down for unobstructed views and an open feeling. Note that the front
panels can open individually to allow quick access in wet weather without
opening the entire cabin. The side panels interlock to create a weather tight
The main reason we do this is so that when the weather is bad, we can
simply close the cabin and be left with one of the biggest saloons and living
areas seen on a catamaran this size and certainly on a performance vessel
like this. The saloon lounge/dining area is massive and well positioned for
views outboard as well as internal living. The galley is very large also. So by
creating this flexibility of space usage to suit the weather, the ideal
compromise has been found.
Instead of creating an internal dining area a similar exterior dining area
we have been able to create a single large area that combines these spaces
and similar needs for greater use of space. The saloon can seat 10 people
with ease as well as 8 for dining (great for when you have guests on-board).
The dining table is a special design that has 4 modes:
- Coffee table with cup tray built in to keep drinks safe when sailing
- 50% dining table for corner seating when raised to table height
- 100% full size dining table that can seat 8 people with real comfort
- Table can be lowered and set up as a large day bed with 2 fill in
cushions. Ideal for watching movies or simply relaxing.
- Similar to the much larger TAG 60, the Galley unit has a built in 42″ flat
- Underneath the seats are moulded storage compartments for long
term food storage. The seats hinge upwards easily to make it very
easy to get into these spaces.
7.6 The headroom in the TAG 50 saloon is outstanding with 2.3m in many
places, 2m is the minimum. What’s unusual is that normally cats have cabins
that are wide and short fore and aft, the TAG 50 enclosed living area is very
large and unusual for this size of catamaran.
7.7 The galley is not unlike its larger sister – the TAG 60. The central galley
bench is 1m wide, which has created a lot of useable bench space. There is
room for 4 x fridge draws, proper rubbish bin and under bench storage one
side and on the other significant dedicated crockery and appliance storage
7.8 Outboard is the stove bench and again this has significant bench space
for a large electric cook top or gas cooktop, with a built in convention
microwave oven and/or grill. Full set of large draws, pots and pans storage
and a daily use food storage pantry. Above the stove is an extractor with
food storage lockers each side.
7.9 Overall the galley is exceptional and you can really live on-board and
create wonderful meals and circulate freely with the open plan design. Quite
unusual on a cat this size and performance.
7.10 The navigation/office table is to port and has a large enough table top
for normal size paper charts, laptops etc. and with lid storage, large storage
locker under and an instrument unit large enough for a chart plotter and all
necessary vessel gauges and communications, this is the nerve centre for
running the on-board systems.
7.11 Each side of the cabin forward are easy/wide stairs down to the guest
cabins. The doors slide open and this alone gives a greater feeling of space
as you descend into the cabin.
7.12 Each side of the master cabin door entries is an illuminated mode
lighting panel. The idea is to have either blue white or red lighting to create
special affects when having guests on-board or sailing at night.
7.13 Each side of the mast post is a sliding door. These disappear sideways
and fully open up the cabin to the main living area. Not unlike a studio
apartment. During the day you leave the doors open and can have good
views forward, not to mention allow massive air movement when the master
cabin window/hatch is opened.
8.0 Master cabin
8.1 The Master cabin on the bridge deck level is something not seen before
on a cat this size. First you have to consider this is a performance sailing
catamaran with reasonably narrow hull shapes. Normally on a catamaran like
this you are faced with a small cabin with a double bed you must climb into/
over that is sometimes too small.
Having said that – this concept will take a bit of getting used to and won’t
suit everyone, yet I think that if you look at the overall concept – what it
gives you outweighs any perceived disadvantages:
The master cabin has a large volume and feeling of space.
Guest cabins are private and considered master cabins in their own
right on any
other cat this size.
When you are in a “hot humid climate”, you can fully open the forward
hatch above the bed to have maximum air inside the cabin. This is a
huge advantage in my opinion compared with hull cabins and air
The hatch is glass and would normally create massive heat in the
vessel as part of the sleek cabin shape. However as it can open, it
allows hot air to escape and avoid the normal build up. When locked
for long periods, the window has blinds on the inside and a window
shade cloth on the outside or if cruising, I would set up a shade
awning over this area and leave it open all the time.
9.0 Guest cabins
9.1 One cabin to each hull and yet you still have 3 en-suite cabins on-board. That’s
luxury. No wasted space trying to squeeze past a bathroom so small you can’t even
move around in. By creating a single cabin in each hull – we not only have better
cabins and bathrooms, we can also maintain our performance package of slim,
performance hull shapes.
9.2 The feeling of space starts as you descend the stairs – instead of reaching the
base of the stairs and having a door forward and aft and a wasted “landing” space,
the cabin uses up all the available space to give good visual and real volume.
9.3 Directly aft is the double berth 2.1 x 1.5m. The mattress sits in a special “tray”
that is hinged at the aft end to give excellent access to the moulded under bed
compartments. The moulded spaces under the bed can in fact fit most normal
suitcases and offers significant long-term storage.
9.4 Please note that these cabins can also be (optionally) set up as single berths as
9.5 Each side of the bed is a narrow shelf to put books, phones etc. as needed.
The cabin has a large opening hatch to the cockpit that helps air circulate and
provides extra light. However – what is unique is the way the cabin receives
abundance of light form the side cabin windows above. It’s a bit like a chimney of
light helping the cabins feel light and less claustrophobic.
9.6 Aft of the main bulkhead is the daggerboard case. It has a furniture unit to
hide it, complete with shelfs and optional flat screen TV…. (I think we have enough
Tv’s already though! Note that hull port is a large size for good views outboard.
9.7 Forward of the main bulkhead is a dresser and another hull port outboard.
Shelfs under the bench top. There is a deck hatch in this area also.
9.8 Inboard is the main wardrobe with full height door that has an optional mirror.
Inside the wardrobe is a hanging space but also a set of shelves for clothes
storage. Some space for shoes also.
9.9 The bathroom is really great. Here you have a great toilet space and hand
basin area with good storage under bench and full size mirror. Outboard is a set of
towel rails and large port, however it’s the shower that is truly great. 2.2m
headroom, full size foot space and spacious. Makes you feel 100% at home.
9.10 The bathroom also has its own deck hatch and with these hatches open and
the master cabin/cockpit hatch open, a good flow of air can be created through the
cabin when at anchor.
9.11 Under the soles are built in Fuel, water and black water tanks. To access the
fillers, vents and plumbing connections, we have a deck hatch fitted into the sole
(as well as bilge pump). This makes life easy should you ever have a problem or
need to do maintenance.
10.0 Bow lockers
10.1 The TAG 50 has long, slender bows, however there is sufficient room in
each bow to storage all the necessary items such as fenders, Gennaker, Code
zero, spare halyards/sheets plus a range of water-sports equipment such as
inflatable kayaks, paddleboards, dive equipment and so forth.
10.2 Access is via the deck hatch and alloy ladder. The locker has a sole that
is set above the waterline complete with valve so it can even be hosed out to
clean it and it will self drain. Storage of equipment is via a SS rail and nets
attached to the hull sides.
10.3 Do you want a fourth cabin? Maybe useful for chartering or as an extra
cabin for the extended family/children. One of the bows we can sacrifice and
create twin bunks one above each other and put a door into the guest
bathroom shower so both cabins share the single bathroom. Storage would
be limited to being under one of the bunks, so I don’t consider it a long-term
11.0 Engine rooms and systems
11.1 Due to our unique layout, the engine rooms are a great size and
located further forward in the vessel for better weight distribution, yet not
inside the sleeping cabins at all.
11.2 Access is via the cockpit hatch and a set of steps. Currently being
designed, the engine room will be home to all mechanical and electrical
components with great access and a clear, easy to understand layout.
11.3 Please refer to the vessel specification for the standard specification
11.4 Directly aft, the lifting rudders are raised manually within a rudder
case. What’s nice about this system is the 700mm quadrant to give great
mechanical advantage for the steering system. We are expecting exceptional
helm feedback. The system itself is pretty simple and rugged.
11.5 Daggerboards are raised and lowered with purchase systems within the
daggerboard cases and the daggerboard posts. Yes you do have to leave the
cockpit to manually raise or lower them, but overall it’s a simple easy system.
11.6 The RIB max size is 3.8m, which is pretty amazing for a cat this size.
There are no davits. Instead the RIB is hoisted via a purchases system within
the cabin overhang back to the traveller winches. Again nice, simple and very
12.0 Sailing the TAG 50
12.1 The TAG 50 is a genuine performance sailing cat. It belongs to the new breed
of sailor who wants to have their cake and eat it. The basics of a performance
sailing multihull are:
- Light weight with optimal weight concentrations
- Sufficiently large sail area
- Slender hulls with high bridge deck clearance, easily driven through a range of
wave states, with lots of low down buoyancy forward/wave piercing bow
- Stiff structure (less platform torsion for improved rig tensions)
- High aspect, performance foils for greater lift for less drag
- Light, stiff rig
- The sum of all details in all aspects of vessel design and construction
Combine these needs with the needs of handling and safety and you have
the TAG 50.
12.2 The TAG 50 will have 3 x rig options:
- Alloy mast and boom to suit lowest budget. Smaller sail plan than other 2
rigs and lower modulus sail material. SS 1 x 19 rigging
- Carbon mast and boom. Non-rotating mast and park ave boom. Simple and
the lightest rig. PBO rigging
- Rotating full carbon wing mast for highest performance and most fun sailing
and for racing. Boom is a carbon V shape design.
12.3 The TAG 50 is designed for a code zero and furling Gennaker to cover most
downwind angles and wind strengths. The furling unit is permanently fitted to the
bow and the sails interchange with a fast pin. There is no downhaul; luff tension is
from the 2:1 halyard.
12.4 The mainsail halyard is 2:1 and the mainsail head is square, so will use a
similar headboard design as the TAG 60.
12.5 Reefing is done at the mast with conventional reef lines to the winch. The
mainsail lazy jacks guide the sail up and down so minimal flaking is needed.
12.6 The Cunningham is lead aft to each cockpit and is an important sail shape
12.7 The self tacking headsail has a 2: 1 sheet split to each cockpit, the track
allows up to 10degres of upwind sheeting angle (8deg optimum). To sheet this sail
wider for blast reaching, we have a folding pad eye and snatch block purchase and
attach the code zero sheet to the sail to move it wider and still keep good leech
