"It is really nice to have a big boat like YC at sea, a genuine delight to sail because the boat will take care of you"

YC / Tripp 90 is a carbon fibre sailing yacht and when you go down below on the boat you are immediately hit with the smell of wood and the scent of leather, it is a wonderful environment. This is a boat for sailing with a short crew, with three sailors on board, you can easily go sailing around the world. 

The Tripp 90 is a boat to go sail around the world, it is going to be a great adventure where the boat takes off for places unknown, crossing the oceans, discovery islands.

We are very honored that Toby Hodges liked Prevail so much as he is one of the most experienced yachting journalists worldwide and has an extensive sailing background

YACHTING WORLD Test review by Toby Hodges

One of the most respectable journalists, beside others in the yachting industry, is Toby Hodges from Yachting World. He took the time to look at and review our Tripp 90 from our custom devision.

Toby has sailed all his life, from family sailing in various dinghies as a toddler/nipper to racing and teaching during school years. Following University, he crewed large yachts professionally to make some money and see the world before getting an apprenticeship with Yachting Monthly, where he worked his way up to Test Editor over five years.

Toby then made the switch to the sister title Yachting World nearly 15 years ago, where he has remained responsible for boat tests and new yacht coverage and the gear and equipment pages, as well as editing the Supersail World and Multihulls supplements and filming most of the yacht tours. He also sits on the European Yacht of the Year jury.

CUSTOM Build Carbon Sailing boat Tripp 90

The latest example of the ability of our Custom Division is YC Tripp 90 a 90-foot-long carbon sloop designed by the American naval architect Bill Tripp. The interiors are outfitted by Winch Design, superyacht design leader based in London. The yacht has been recently launched in May 2021 for an international customer that intends to sail in regattas as well as cruising worldwide. 

On one hand, we have been trying to ensure the best-in-class interiors, with volumes equivalent to 100 footers. On the other hand, avoiding exaggerate lengths, Tripp 90 can perfectly suit with a human dimension, keeping away useless spaces that are difficult to manage and maintain. 

A boat with a lot of value and beautifully finished with great sailing capabilities. It is a boat designed to go sail around the world for long and fast cruises. It is going to be a great adventure where the boat takes off for places unknown, crossing the oceans, discovering islands.

YYachts has managed to produce a yacht that can be sailed safely with impressive sailing characteristics, high speed potential and yet simple operation. 

What about the new Tripp 90?

Hi, I am Bill Tripp, the designer of the new 90 that is just launched by Michael Schmidt Yachtbau. I am really happy to have helped arranged the building of this boat with this yard it has been a great collaboration. The new boat here I think is really a new goal that other people are going to have to try to meet now. A boat with a lot of value and it is really beautifully finished that sails really well so far. I am really excited about what this boat will do with for our client. It is a boat to go sail around the world, it is going to be a great adventure where the boat takes off for places unknown, crossing the oceans, discovery islands. It is going to be a great time for everyone involved and the yard is really step up with this boat, I am really happy to be here.

Sailing the Tripp 90 what is unique?

Really this is a boat for sailing with short crew, I think with three sailors onboard, this is a boat you can take pretty much anywhere. Of course, do watch when you go at sea but I would say with three people you can sail with this boat pretty comfortably with. A boat of this size, we find the biggest trick is getting the boat in and out the dock. We have got thrusters and the boat handles really well. I think the boat as soon as is out of the harbour, the boat really is easy to sail. It is really nice to have a big boat at sea, because the boat will take care of you.

What is your favorite feature on the Tripp 90?

I think the way we have been able to proportion the boat with the yard in term of building the boat out of carbon, putting a lift keel on the boat, with the twin rudders, we are able to get a boat that while it has all the equipment of a true cruising boat it is a boat that will sail really well. In power boats you are always saying are we there yet and in sailboat we are here. I think the enjoyment of the use of the boat will come first.

What was the hardest part on the Tripp 90 project?

I think the hardest part of putting together a project like this is to make the technology invisible, because you want all the technology makes the boat very very usable, but you don’t want to see it. It is like in an I phone, you don’t want to know what it is inside. In here we want the lifestyle of the boat to come through, the use of the boat to come through and you do not want to see what makes it work, and getting all of them integrated into the boat, hiding them away in the spaces has been a challenge but also very rewarding.

What about the unique technologies onboard the Tripp 90?

Well, the lifting keel would be one example of it, integrating the location of the lifting keel into the interiors so that you do not realize that the boat has a lifting keel it was one of the first places we had to start. Having the engine room under the saloon, so that you have the whole volume of the boat all the way through, and you do not lose it into an engine room.

What is the benefit of a lifting keel?

The benefit of a lifting keel is we can sit here inside the shallow harbor and have this lovely conversation, and you can do that in Saint Tropez or you can do that in Black Island. When you go out of the harbor and put the keel down, the boat is much easier to sail because of it.

What is special about a light boat?

A light boat makes the boat much easier to use, and the advantage of a light boat is that we start virtuous spiral, where we are able to have a bit smaller rig, wider engine, less fuel, and we evolve the boat into a boat that is easier to use, and less complicated.

Lignia Wood what is this?

This is the second boat we have done with Lignia Wood, the wood here is quite a beautiful looking, veneer over the deck it is great to walk on, it does not get hot, it feels and looks like teak and we are not cutting down trees in Burmese for it. I hope that this becomes the future, here we are using less wood to do the same thing.

What is special about the way the Tripp 90 is built?

Sitting here on a carbon composite boat, it is built in epoxy, it is not a plastic boat and when you go down below on the boat you are immediately hit with the smell of wood and the smell of leather, it is a wonderful environment, it no longer smell like stirring, it is a completely different world, you feel like you are in luxury hotel, you feel like you came to a place where you really want to stay.

90 feet of pure smooth sailing

What about the design of the Tripp 90?

The linear design of the boat incorporates a very long pilot house for inside the boat, and we managed to put vertical windows of the boat, what that does is that expands in feel of inside volumes of the boat, and also prevents slides from hammering into the interior needing to run more air conditioning in result.
In this way the light comes in and keeps the boat cool in the same time, so that is of course, more energy efficient, it also means run the generator less, it means you can go with battery power more often and therefore you burn less fuel and you can go further with the same amount of fuel. So again, that is another example of virtuous spiral.

Thanks to an advanced hybrid diesel-electric drive and a large battery bank. Perhaps the YX PURE is the greenest research vessel in the world. Its two-bladed propeller allows the batteries to be recharged under sail even at hull speed.

Custom-project reserach vessel „EUGEN SEIBOLD“

One of our most demanding projects to date was the construction of the "Eugen Seibold", a highly innovative yacht designed for environmental research. We received this commission from the Swiss Werner Siemens Foundation and handed over the completed yacht in autumn 2018. 

Since this time the "Eugen Seibold" has been managed by the renowned Max Planck Institute to enable global scientists to conduct climate and marine research. Professor Gerald Haug, today's President of the LEOPOLDINA (German Academy of Natural Scientists), Director of the Max Planck Institute, and Professor at ETH Zurich, navigated many obstacles to direct this ambitious project into today’s welcoming waters. 


The hull is mostly made of classic glass fibre, with carbon fibre reinforcements. Her elegant lines come from the pen of Lorenzo Argento. Nevertheless, the requirements for the "Eugen Seibold" are very different to those of a private yacht. Due to an oversized hull, the research sailer weighs a maximum of 44 tonnes fully loaded with equipment.


Research vessels are few and exploring oceans is expensive. As a solution, YYachts developed the 22-metre research yacht YX Pure.

The "Eugen Seibold" is named after a German marine researcher, and supports scientists and others in researching climate change. Its main task is to carry out long-term observations in certain marine regions with a comparatively low budget.

Sail controls are hydraulic, as well as the lifting A-frame gantry on the transom. This unique fitting can drag nets or raise water samples from up to 2500 metres’ depth. The samples are packaged below deck and deep-frozen. In addition to a 170hp six-cylinder diesel, a 288 Volt generator and two electric drive motors with lithium-iron-phosphate batteries were also installed.

The interior is user-oriented and practical. Key features include the second companionway to the aft deck, as well as the deckhouse. Eight berths are offered by the YX PURE, in addition to some laboratory space.

The "Eugen Seibold" was financed by the Swiss Werner Siemens Foundation, which specialises in research funding. The sponsor is the German Max Planck Institute.
