Covers for Hulls and Mast

For road transportation or moored at the dock or awaiting sailing on the trolly on land a cover is what you looking for. Now we have made super duper covers for mast, boom, crossbar, front beams, floats and mainhull. Also available is the special cockpit cover that let you keep the hatches open, sails on the seats for drying out and sun protection. Works a treat!

Boom Cover works on land or…

…in the wet.

First SeaCart 26 in Norway

A bright April morning we went west to launch a newly striped SeaCart 26 trimaran. Here’s the picture story in reversed direction from floating sail test in Oslo to striping in the work shed outside Stockholm, Sweden. We look forward to post updates from training and racing sessions. Until then enjoy this!

Nice docking space at the KNS dinghy plant.

Just a small push and she’s afloat.

Removing the last straps around the main hull.

Both sides out. Furling lines getting in place. Covers already removed. Looking good!

Mast in place and one side is folded out. Take up 30–40 cm on the shroud to get her leveled.

A-Frame in place, mast goes up.

Ready for the road.

Checking the straps.

All looking good on deck. Covers do their job perfect.

Graphic waves in place.

Flag and number now on the floats.

Inside float graphic.

Outside float graphic.

Those guys know how to do bend the corners.

High concentration is the only way to get this right.

Journalist Flemming Thomsen visited the factory in December 2011 and had a long chat to Calle Hennix, the man behind the SeaCart Trimaran brand. The result just landed in the Danish shops. Six loaded pages with text and pictures. Text in Danish but still lot of interesting pictures from the factory to scrutinize for those not understanding Danish. Enjoy!

Racing Systems as Standard!

The SeaCart 26 is a piece of racing art fitted with the best brands in the business

The SeaCart 26 is a One Design racing boat that comes with advanced racing systems as standard. This reflects Oceanlake Marine’s philosophy where we strive to deliver the best and most effective solutions and systems on our boats – So there is no need for an extensive refit to get your boat up to racing level after delivery!

– Carbon beams, carbon rudder heads, carbon reinforcing on the three hulls
– Carbon mast in two parts, single spreader, Dyform diamonds stays (single adjustment)
– Custom built, pre-stretched, 12 tonne rated shrouds. Hull lashing through Antal rings
– Carbon boom including reef system, outhaul and all lines needed
– Harken under deck jib furler
– Most of the sailing hardware, such as blocks, cleats etc. from Harken
– Dyform furling forestay in two pieces

Here you can check out many detailed equipment pictures.

Sailing Systems Liros Dyneema, Karver, Custom made…

– Floating jib sheet points. Adjustable Antal sheet rings on each side. One line adjusts both sides
– Jib halyard system. 1:24 to cleat on jib tack
– Jib sheet big trim (1:2) and fine tune system (1:24). Fine tune lead up to windward float
– Main halyard through Spinlock at mast for easy hoist and reefing
– Main sheet big trim and fine tune system. Fine tune lead up to windward float for trimmer
– Extensive cunningham system adjustabe from windward side on each float

The Code 0 systems (extra equipment)
The Code 0 are hoisted onto a Karver halyard lock. The deck Karver KF1 furler is attached to a 1:4 line system that goes through a side mounted Spinlock on deck, then to winch. This provides a high load purchase system (as on a VOR 70) to tension the halyard. When the tension is taken off the forestay (jib) the Code 0 luff loar is OK.

Code 0 Extras
– Karver KF1 furler including 1:2 tack sheeve
– Karver halyard lock, attachment point at mast is standard
– Code 0 sheet inhaul through hull fittings and harken cams at each side of mainhull
– Code 0 sheet outhaul attachment point at each float into cams at mainhull
– Antal Code 0 sheet clev rings
– Large Harken turning blocks at aft beam
– Dyneema highest quality racing sheets
– Endless furling line in Dyneema

SeaCart 26 Test by Torvar Mirsky and Gustav Morin

Torvar Mirsky and Gustav Morin put the SeaCart 26 to the test. Tim Shuwalow took Torvar and Gustav out for a spin on a late gusty summer day. Check out the result by clicking on the picture. Don’t miss if you would like to know how you can do boat tests in a fun and informative way (site in Swedish).

Torvar Mirsky: Often compared to the likes of match racing superstars such as James Spithill and Peter Gilmour, Torvar Mirsky is the new young gun to take the sailing world by storm.
Torvar on Facebook

Gustav Morin: Gustav Morin has always found his inspiration of journalism in being a part of the action– instead of standing on the side watching it. In 2007 he joined the Victory Challenge team for the America’s Cup in Valencia as a grinder. The pretty unique mix of experience in yachting and media now got him the opportunity to experience the ultimate sailing adventure – joining Ericsson 3 as the media crew member for the Volvo Ocean Race 2008-2009.

Flow & Membrain Runs On the SeaCart 26

The team behind the SeaCart 26 has not saved any energy or expense in our aim to provide the market with the best sports multihull package possible. To make sure the mast and sail shapes are optimized an extensive flow and membrain program have been run using input from test sailing sessions and racing the first SeaCart 26. The findings have been implemented on boat No 2 which is now out sailing.

This sounds like a lot of mumbo jumbo but it is in fact extremely valuable if you are serious about your intentions. For those who would like to read further into the matter we have posted North Sails notes on the subject below. When you read on you get the picture that this is not an task done quickly in a few minutes, to the contrary, it’s seriously time consuming and highly scientific. Pictures in the article show a SeaCart 26 under OD Gennaker.

DESMAN [TM] … rig and sail modeling. Desman creates a complete rig/sail model in a three-dimensional environment. In Desman, North designers can specify mast size, rigging position, rigging attachment points at the deck and trimming locations. The modeled sail/rig system incorporates the mechanical properties of the spars, standing rigging, running rigging and sails in terms of moments of inertia, sail and spar surface area, materials stiffness and resistance to stretch. Later in the process, Membrain (described later) uses the Desman model to determine deformation under load for the sail and every piece of standing and running rigging, right down to stretch in the sheets and halyards. Link to North Sails Desman.

3D LAYOUT [TM] … define the structure of sail. 3D Layout is used to define the structure of a sail in terms of yarn layouts, panel layouts, tape layouts, yarn density, and/or film types. Output from 3D Layout is used to shape 3DL molds or provide seam curves for paneled sails. All yarns are plotted in the same 3-dimensional space they will assume when sailing. 3D shapes are translated into panel layouts for downwind sails. 3D Layout also has powerful analytical tools which can be used independently or in conjunction with Membrain. Link to North Sails 3D Layout.

FLOW [TM] … applies wind pressure to 3-dimensional sail mold. Using Flow, wind pressure is introduced over the sail’s three-dimensional “mold” to produce a pressure field on the sail’s surface. The pressure varies over the surfaces based on the size and shape of the sail and the strength and direction of the air flow. The resulting pressure field is then linked directly to Membrain for finite element analysis. Flow also reports the drive and moments developed by sails, which can later be used by either the North Sails VPP or other VPPs for sail performance analysis. Link to North Sails Flow.

MEMBRAIN [TM] … balances wind pressure, sail shape and rig. Membrain takes the sail/rig model from Desman and applies pressure fields from Flow, deforming the mast and sail as a single unified structure. As the sail/rig structure is deformed, the shape of the sail changes, so Membrain then links back to Flow to acquire new pressure fields for the deformed surface. This changes the sail shape in Membrain yet again, so the process is repeated until there is stable balance between pressure and rig/sail deformation. Membrain can be used to test sail shapes, optimize mast design and rig tune, create sail shapes to test in North VPP, check loads for designers, and more. Membrain applies pressure to the integrated rig/sail system and then iterates the results back to Flow until pressure and sail deformation achieves a stable balance. Link to North Sails Membrain.
