Function and Style
Wally Power Passerelle
La Scala Gangway Series
Our first “la scala” was built for the 118 foot wally power. This is a fully automated unit using a remote control pad. It can be used as a flat platform for sun tanning or to pass to the dock with the same level. The angle of the stairs is individually controlled via hydraulics. Therefore the steps can be adjusted independent from the angle of the frame structure. All our scala models have this feature. The up and down angleis +/- 40°. The large aft step is just above the water when the gangway is in its lowest position, allowing the guests to take a swim using a small bathing ladder. The platform is 2.0 x 2.5 metres. The all up weight is 147 kgs (as opposed to 700 kgs for a metal unit) the work load on this gangway is 600 kgs
Four different Scala types are available:
Fully automated with longitudinal in and out action from 600mm x 3 metres to 2.0 metres x 3.0 metres.
Fully automated pivoting unit. The passerelle is stored transversal in the stern and pivots out 90° using a torlon ball bearing pivot housing in machined aluminium. Up and down movement is +/- 40° . The step angle is individually adjustable to use the gangway as a bridge. When lowered 40° the lowest steps are in the water to make it convenient to access the water without a bathing ladder. Passerelle size 3.0metres x 600mm x 350mm. Weight 68 kgs, working load 300 kgs.
For the sailing yachts we developed and manually operated system. The passerelle is stored under the stern floor. To access the passrelle a hinged hatch is opened, the passerelle is attached to carbon gooseneck hinges at the stern and lifted up by hand and pivoted aft. The masthead topping lift is attached to take the load and to controll the up and down angle. Weight 37 kgs, working load 400 kgs.
The forth unit is the Scala Reale, the kings stairs.This gangway has been developed for superyachts above 30 metres and cruise ships. It is stored underneath the side deck and is fully automated. It moves transversal out of its storage place and is then lowered 45°. This allows the crew to access the quay from a higher deck level or, when anchored to access the yacht with the tender.Weight 185 kgs, workload 500kgs.
Manhattan Passerelle
The Manhattan model is a development of the Newport passerelle, but it has a fixed storage place in the stern deck similar as the scala gangways. Its size is between 3.0 and 6.0 metres x 650 to 800mm wide to allow access to the yacht with a wheelchair.
It is either fully automated or hand operated. In and out movement with an electric winch or using a block and tackle with ropes. The up and down movement is controlled hydraulically or with the masthead topping lift. As an optional feature we offer also an additional transversal pivoting action +/- 40°.
The 3.0 x 600mm automated Manhattan weighs 68 kgs with a working load of 400kgs and the same size manual Manhattan weighs 38 kgs with a working load of 400kgs
Newport Passerelle
The Newport passerelles are available either in one piece, or foldable, flat or curved. The flat model is built in sandwich with 25mm foam between the carbon prepreg laminate. The curved Newport does not have a foam core. The top surface is very slim monolithic laminate. This surface is then reinforced underneath with a u curved u-channel box also monolithic. All Newport gangways have to be stored manually in a storage room.
When approaching the yacht this passerelle looks very thin and fragile, when in reality it is very stiff and strong.
Bowsprit
The bowsprit/anchor support for S.Y.Sapphire Knight has been built using carbon prepreg. The cured part was then glued to the bow with high strength two component epoxy adhesive. The final lamination, transferring the loads from the gennaker and anchor chain to the hull, was done in wet layup. The original hull has also been laminated using wet layup. Epoxies used for wet layup lamination have a lower temperature resistance than prepregs. This means that it is not possible to put enough heat around the laminated area to cure a prepreg part without the risk of distorting the hull. We post cured the final lamination at 60°c for 12 hours. Applying prepreg we would have needed 90°c.
The gennaker attachment has been engineered to withstand 8 tons of vertical load and the anchor part for 10 tons chain load.
