"Let me tell you about my boat"

LA 35 is designed by Henning Laurén 1971 at Parainen

La 35 is a sloop type, a single mast sailboat with two sails. It normally has one rectangular triangle -shaped main sail and one head sail, the size and model of which can vary from a narrow storm sail to head sail, a Genua, which extends to the half of the main sail.

Simman has ordered and built bt Bo Sigfrids from Parainen at the turn of the 70s and 80s. Simma has cost FIM 50,000 on the frame and cover (fiberglass). The original engine has been the Yanmar 2GM20: 2 cylinder, 1.1 L, 22 hp, 220 kg and seawater cool. Simma is registered in the ship register on January 1, 1981, when it was completed and the engine warranty period has begun. The engine and the maritime gear lasted 38 years!

How does Simma differ from other Laurens?

Lauren LA 35 boats have been made in Parainen a 30 boat series. S/Y Simma is a unique boat distinguishing from this series with a streamlined deck. Although fiberglass boats are made with mold but Simma's deck is not made with mold.  Unlike vertical Lauren's decks, Simma's deck is streamlined as in racing boats and is completely covered with a teak.

There are many Laurens, but only one Simma.

Rarer than rare <3

Ocean Cruiser

The 35-foot sailboat is just the right size for crossing oceans with family, but also for solo sailing.

There is plenty of space for the smooth shape, and as a fin-keeled boat, the weight is suitable for handling in different conditions.

Tapio Lehtinen sailed in Golden Globe Race 2022 -the same size Asteria boat around the world. Or well almost. The boat hit a semi-reckoned container in the Indian Ocean 700 km southeast of South Africa. The probability of winning the lottery twice is greater than this.

Classic lines

Boats from the 70s and 80s are classic and sleek in shape. There is not as much space as in modern boats, because after the middle the hull narrows towards the stern, unlike in boats designed after the 2000s and 2010s, where the hull practically does not narrow towards the stern at all.

In practice, a boat that is 10-20 years younger has, in addition to one aft cabin, as much room inside as a second aft cabin. A 21st century boat after 30 foot is as big inside as a 35 foot boat from the 80s. But otherwise, a 30-footer is a 30-footer and a 35-footer is a 35-footer.

Simma's performance values

Sail Area / Displacement Ratio: 16.97 (Genoa III), 19.48 (Genoa II), 22.39 (Genoa I)

<16: under powered
16-20: good performance
>20: high performance

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes.

Ballast / Displacement Ratio: 41.82

<40: less stiff, less powerful
>40: stiffer, more powerful

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Displacement / Length Ratio: 228.81

<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond.

Comfort Ratio: 24.15

<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness.

Capsize Screening Formula: 1.95

<2: better suited for ocean passages
>2: better suited for coastal cruising

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions.

Hull Speed: 8.17 knots (15 km/h)

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power.


I want this boat! And I'm going to win it!

When I found Simma, everything fell into place except that Simma had already been sold to another person. There was no need to bet, let alone dance, but it required a good story and a suspense drama of the day before we could write the sales documents.

The lesson of the story is that when you want something, pay a down payment and make a deed of sale. Otherwise, an old Swedish salty sea dog might grab a good deal.

Simma has been bought for the same amount as it originally cost Bo with the frame and deck ready before 1981.

How did the idea for Sunset Sailing Tours come about?

In the summer of 2019, I was on vacation in Portugal and watched sailboats going by Cais do Sodré beach in the evening sun. The sails up, the deck full of people, they were going with engine in a calm harbor pool back and forth. I thought I would do it much smarter, but it seems to sell like crazy. It gave rise to the idea of a similar service that was stewed for a couple of years. Originally called Gast.events, but Gast, to which the name of the service refers, is not a very well -known term more broadly. Although the visitors came to the site quite nicely, it was often the lost who were looking for casting, that is, a modeling agency and not sailing. So the name changed to more and better descriptive form.


My mentor

Seppä Risto has been an valuable help with the boat. There is no such thing that he does not know, and the result is better than in boat repair shops. If you ask Risto, I don't owe him anything. If you ask me, I owe him everything for his unsolicited help. The thing with a boat is that no matter how much money you have for maintenance and doing things, you just can't buy everything. It is good or even necessary to have a mentor who knows how and shows how to do things. Youtube is of course helpful, e.g. by following the sailing channels offering on behalf of DIY, but there is still a long way to do things yourself.


The sauna was designed by a Russian space engineer. It is not only incredible that this three-four person comfort facility fits in a icehockey bag in a boat, is erectable in one quarter and warm (80 degrees) in the other, but that he has been able to create a better sauna in the darkest corner of Siberia than anywhere else in the world. In addition to the sauna tent and the stove, the sauna naturally includes benches, a water heater and an outdoor tent, which forms a sheltered and warm dressing room/shelter around the 2 x 2 x 2 m sauna tent. A 40 L sack of wood and 20 L of fresh water will comfortably last you through the weekend.

Swedish masseuse

The ship's crew includes, among other things, a Swedish masseuse. 

Check out the whole crew here.

Kitchen has the latest tools

In addition to hot running water, the kitchen naturally has a dishwasher and gas stove with oven and grill, ice maker, Margarita mixer, refrigerator, freezer, Cappuccino machine, sous vide and charcoal grill.

The last addition is a gas pizza oven that heats up to 300 degrees for 10 minutes. It prepares restaurant-quality pizzas with a crispy base in 60 seconds. The pizza bases go well in the freezer of the boat, Mutti's mashed tomato in the dry cupboard, Latte Di Mozzarella in the fridge and the only green plant on the boat, Basil, thrives well in a pot in the boat's microclimate. When grilling  gets boring, Margherita con Salame pizza has never tasted so good. For the next restaurant day, I should probably get pizza boxes and start the best pizzeria on the island. There is no doubt that the pizza will sell like crazy.


Naturally, there is a fireplace and a library on board, with e.g. the complete works of Jacques-Yves Cousteau's Secrets of the Seas.

Who could tell us more about the seas than the old gentleman of the French Navy, who invented scuba diving 80 years ago and was a pioneer in the protection of the seas and nature. He saw over 60 years ago the traces of human activity on his adventures in the seas of the world and making documentaries for us about it.

Oh, and that fireplace produces 1000 W heat and 1 MW atmosphere. 0.4 l bioethanol burns for over an hour and costs a euro. No need for chimney, wood,... safe, neat and handy.


Cutting room

Working on the board is comfortable. If you want to work on boat's bow with a pad, laptop from a birth or need a bigger screen and a better keyboard/mouse, then there are alternatives to the projector's 40 -inch screen in the ship's salon.

Or take your laptop to the island because the boat's Wi-Fi covers hundreds of meters.

Underwater observation bubble

In addition to diving, Cousteau invented e.g. underwater observation bubble to Calypso, underwater photography, underwater scooter and much more.

Today's sonar technology is so advanced that with the Real Vision 3D sonar you can see under the ship as if you were looking below the surface from a glass-bottomed boat.

Fishing becomes really easy when you can use the echo to locate a school of fish, put the hook in the mouth and reel in the catch. From the link below, you can see how Juho and Sohvi from the Alluring Arctic boat handle the procurement of food in just over a minute.

A real life fish story



Porpoises often swim around the ship. However, I have only noticed almost uncertain signs of this a couple of times.

The world's smallest species of toothed whale lives regularly in Finnish waters, but only a few have seen it. "But they do live here in our waters," assures Olli Loisa, the special expert responsible for monitoring porpoises.

Helsingin Sanomat has the story.

Engine room

The main machine of the boat was replaced in 2019 with the new Volvo-Penta D1-20 engine with a sea gear. This 0.8 L, 3 cylinder, 19 hp Perkins manufactured, a freshwater cooled 130 kg diesel engine completely utilizes the energy of 1.25 L diesel/h (2000 rpm): 5 knots speed, 115 A power and 20 L hot water boiler heating, 10 kW interior and interior and 5 kW cockpit heating of engine waste heat.

When you go with motor, the cost is a couple of euros per hour, the journey is about 10 km, and in addition to the previous ones, 115 A power can make 60-70 L of clean water in the fresh water tank with the watermaker and wash dishes or machine laundry and dry them. Yes, there is a Daewoo Mini 3.5 kg tumble dryer on board.

Of the diesel's 1.25 liter 15 KW calculated energy, not a single watt is wasted.

On the other hand, the boat's solar panels and the wind generator produce as much electricity as the engine, so you don't have to burn diesel because you can enjoy these little luxury of life at sea. For example, a vessel 5000 BTU (power requirement 560 W MAX) air conditioner runs with a flow of 1400 W of solar panels and keeps 15-25 square meters insulated interiors in a pleasant and dry even in trophy.



Every sailor who produces content usually has a drone to record the incredible scenery from a bird's eye view.

Fortunately, in today's world, things are much easier than in Cousteau's time. When the number of hands is limited, flying the drone becomes challenging. Fortunately, controlling the DJI Mavic Pro is an app on the Raymarine Axiom multifunction screen, i.e. the so-called on the chart plotter.

When there is also a 360-degree camera, everything can be captured at the press of a button, and later in the editing phase you can decide in which direction you want to save the camera image or let the viewer decide with VR glasses, for example.

Mini sub

What is still clearly missing from the ship's equipment, in order to stay at the sharpest point of Maslov's hierarchy of needs, and which is really an important and handy piece of equipment, is a diving robot, i.e. ROV or underwater drone. FIFISH represents the latest generation of these products. With it, you can check the ship's hull, propeller, rudder, anchor, search for and rescue a mobile phone, camera that has fallen into the water... and of course, at a dive site, such as a wreck, do a pre-dive and check that you are in the right place and what the visibility is like before you start weighing the frogman's equipment on.


Underwater gadgets

I started diving in 1986 (CMAS) and graduated as a diving instructor in 2008 (PADI). I have left the training to the younger ones, but I like to dive on trips to southern waters with Risto, whom I have introduced to the most intimate areas of diving.

The ship has diving equipment and, of course, a high-pressure breathing compressor for refilling oxygen bottles. This too has its own story to tell, but for me, this third compressor left over from the dive shop has perhaps the most cherished meaning, in addition to the brand, the year of manufacture: 1976.


She didn't really love me :(
