True North Yachts сувгийн бүтээгч Лукас Сжоман өөрийн гараар угсарсан 11 метрийн урттай Helios 11 дарвуулт завьны хийцэд гарсан зургаан үндсэн алдааг ил болголоо.
Завьны ёроолын хэсэг хэт хавтгай хийгдсэний улмаас давалгаан дунд дуу чимээ ихтэй байгаа нь ашиглалтын явцад хүндрэл учруулж байна. Мөн өвлийн улирлаас зугтах гэсэн яаруу шийдвэрээс үүдэн муруй хэлбэртэй хийсэн хөлгийн хоншоор нь ус зүсэх чадварыг бууруулж, усан дээрх үр ашигтай уртыг хязгаарлажээ. Үүнээс гадна, моторын таг нь арын нарлах талбайг хувааж, ашигтай талбайг багасгасан нь дизайны бас нэгэн дутагдал болсон байна.
Техникийн хувьд бүхээгийн хаалганы өндөр 150 см байгаа нь 190 см өндөртэй хүн нэвтрэхэд хэт намхан байгааг зохион бүтээгч хүлээн зөвшөөрлөө. Арын хэсэгт байрлах сэлэлтийн тавцан нь хөлгийн урт болон үр ашгийг нэмэгдүүлэлгүйгээр зөвхөн сул зай эзэлж байгаа нь нийтлэг алдаа гэдгийг тэрээр онцлов.
Эцэст нь, нарны эрчим хүчний хавтангуудын сонголтод өөрчлөлт оруулах шаардлагатай байгааг тэрээр дурдлаа. Уян хатан хавтангууд нь илүү өндөр өртөгтэй бөгөөд эдэлгээ даах чадвар сул тул ирээдүйд суурин хатуу хавтангуудыг ашиглах нь илүү үр ашигтай гэж дүгнэжээ.

The man who built a solar-powered yacht shared an update about his boat.
But, for once, it isn’t about a new addition or a redesigned section.
On this occasion, he shared the six mistakes he made while building the boat.
Including a ‘sacrifice’ he made simply for fun.
The man behind the True North Yachts YouTube channel, Lukas Sjoman, shared an update detailing six design flaws, mistakes, and compromises in his 11-meter solar boat, Helios 11.
Some of them would’ve been difficult to predict, but there’s also one that should’ve been easy to spot from the start.
And then there’s one we can’t really blame him for.
Flat underwater sections
The first problem is the underwater sections of the hull, which are too flat and create noise in waves.
Apparently, that’s particularly annoying at anchor.
The yacht has a curved bow
The bow was built out of convenience to escape winter, but the curved bow limits the boat’s effective waterline length and wave-piercing capability compared to a straight or reverse bow design.
To be fair, he took full responsibility for this.
“The second flaw, mainly credited to my laziness or hurry to escape the Nordic winter in time, is the curved bow,” he admitted.
Split rear sundeck
This isn’t a massive deal, but it just eats up usable space in a boat that’s not particularly large.
The motor cover interrupts the sundeck, making it less functional.
A better idea would’ve been to elevate the deck and sink the motor.
“This has nothing to do with the speed. But there’s just less space,” he said.
The cabin door of the yacht is way too small
This is the design flaw that could’ve been predictable.
While there’s enough headroom in the cabin itself for people who are around 190 centimeters (around six feet and three inches) tall, the entrance is only 150 cm, which is way too small.
A hinged solar panel setup would’ve solved that problem, and in fact it might.
He’s thinking about it.
“I thought ‘I’ll fix this later’, but this is a full-time liveabord, not a camping boat. So what we need is hinged solar panels,” he said.
The yacht’s swim platform is a little inefficient
The extended rear swim platform is essentially dead space that doesn’t contribute to anything else.
“Almost all hulls have this flaw. It is an extended swimming platform that make the boat longer without increasing efficiency,” he said.
But we can’t really blame him for this.
What’s the point of a boat if you don’t have a swimming platform?
The flexible vs hard solar panels dilemma
The solar-powered yacht owner realized that flexible panels are more expensive and less durable than basic hard panels.
Roof-mounted hard panels for better cost-efficiency.
In the video, he admitted that he preferred the older ones but still decided to switch.
“I loved flexible panels in the beginning for their lightness and pretty all right efficiency, but now I would prefer to have only basic hard panels,” he said.
Despite the lessons learned along the way, Sjoman’s solar-powered yacht remains an incredible build.
