A 28'-33' monohull or multihull yacht for transport, for inland and offshore sailing...

In the past, I've owned 7-8m sailing yachts and chartered 7-15m yachts, so I have some observations and concerns...
I've sailed on both monohulls and multihulls.
Each has its advantages and disadvantages... but the most important thing for me is safety.

Anyway, there are so many variables that it would be appropriate to create a mathematical inequality, or, more simply, a pros and cons table (SWAT analysis)?

That's why I'm seriously considering building a yacht...will there be an auction?

1- monohull with water ballast,
2- catamaran
3- trimaran
2 and 3 foldable for transport, and that should weigh no more than 3500kg with a trailer, so now we'll see if;

A- according to the purchased documentation
B- according to our own documentation based on PRS guidelines

WHAT DO YOU THINK?

 

Skoota 24, extended to 28’

 

An interesting design, certainly cheap and quick to build. The appearance is less impressive, and as I mentioned, plywood... as long as it doesn't absorb water, it's fine. Then, as a rule, wherever water is absorbed, the component needs to be replaced, and I'm writing this based on my own experience. All it takes is a hole that's not properly secured or develops during the stresses of sailing.

 

For construction or design, I'll use rigid foam and the resin infusion method.

 

Boat+ trailer , why it should weight no more than 3.5ton ?
PRS ? You make me laugh. you don't need purchased docs or PRS . We have EU law already .You can build boat till 15m as you own design .And you are obligued to not to sell it during 5years or something .

 

True, the gross vehicle weight plus the gross trailer weight will definitely exceed 3500 kg. There's no other option.

Regarding PRS, assuming you don't need insurance, it's fine. However, in any other case, it's better to build according to the requirements than to "fly it." Everything is fine if you're sailing alone and you die.
Of course, insurance doesn't guarantee you'll survive, but it's about responsibility for what you do because you could hurt someone else.

I won't describe the behavior of motorboaters on the water, for example, in Masuria (their indolence... or mental impotence - the more expensive the yacht, the higher the speed).

Besides, I'm not a fan of motorboats... they don't offer freedom, unless they're powered by electricity from the sun... or wind. I worked in electrical engineering for many years... so unfortunately, I know a thing or two about this, and things always go wrong.

 

Because that's the weight limit one can tow in Europe with a normal car plus trailer (B+E) driver's licence. Total allowed combined gross weight is 7000kg, broken into 3500kg car + 3500kg trailer.
If you want to tow a trailer that's heavier you need a light truck (3.5t to 7.5t) as a towing vehicle and a C1+E drivers licence (or full C+E). This brings you into another tax bracket, both for the vehicle itself and for the road tax. It's an entirely different universe, even as a non-commercial user.

If you stay in the BE brackets the actual boat weight (equipped for travel) is going to be maxed at ~2.7-3t, depending on trailer lenght and material (steel or Al). How much weight the car itself can carry before it reaches 3.5t depends on the specific model, it usually peaks at around 1t.

 

Not too many vehicles other than trucks that can tow 3.5t. Maybe some larger suvs. I had a Chevy Traverse that could pull 5000 pounds, but after about 6000 miles towing a trailer; the tranny slipped a couple times and I sold it to the dealer.

Here in the US, in some places, trucks are 80% of the vehicles on the road, so this conversation is a culture shock for me.

 

In a nutshell you can think of it like this, everything that can legally tow something over 3500kg is a commercial vehicle requiring a commercial drivers licence even if it's used privately. For various reasons most people don't go there if they don't absolutely have to. To complicate matters in some countries its cheaper to register a 3.5t GVW vehicle with a big displacement engine as a commercial so you get crazy stuff like a luxury SUV modified and declared as a light truck because the yearly tax is significantly cheaper and offsets the increased insurance cost.
So we tow our bigger boats primarily with a mix of true offroaders and SUV's with a few small pick-up trucks and big vans to broaden the panel. Typical vehicles an american would have at least heard of are VW Touareg, BMW X5, various Land an Range Rovers, Toyota Hilux, Ford Ranger, Jeep Grand Cherokee and others. Yes you can buy an F150 or a Dodge Ram over here, but they are still limited to 3.5t towing capacity because otherwise one needs a CDL. But, american style pick-ups aren't really a thing here, simply because they aren't practical, our cities and parking spaces aren't buildt for them. Tradesmen use panel vans, and they often have to squeeze themselves out of them because there's simply no space to open the door further, and their ends stick out into the road past the marked space. Complicated parking maneuvers are a fact of life.

Another thing that bites us are emission zones, a lot of the older (and therefore cheaper) vehicles can't go into certain cities, so you either buy a newish one or a really old one that can be registered as a historic vehicle (wich is its own can of worms).

 

What are the regulations for trailers? In most American countries they allow long objects, like powerline posts, and girders to be towed with a hitch attached to one end and a dolly on the other. A boat could be towed like that avoiding the weight of the trailer frame.

 

It depends on the specific jurisdiction, but generally approved, registered and inspected, sometimes with separate insurance policy. The range varies from UK liberal where you just slap your car license plate on the back of whatever trailer you find to countries that require regular inspection intervals.
Self builds are generally possible if relevant parts are type approved (axle, brakes, lights, towbar) and rules followed (no welding on axle and towbar for example, only bolted to the frame). Some jurisdictions have additional hoops to jump trough like all welding has to be done and documented by a certified welder, etc. All countries have builders specializing in boat trailers that do full or semi-custom fabrication including all needed paperwork. The sh market is full with weird GVW ratings because owners specified or derated a trailer to match their specific vehicle. Uprating such a trailer isn't always easy, especially in some jurisdictions.

The type of separate dolly you describe I have only ever seen as a specialized log carrier for fifth wheel coupling equipped trucks.

 

I've meet german family in Cro . They travelled by old MB fire truck .
Missis touched me when she started displaying her home flowers in pots at the campsite...

I have a category C and I'm tempted by a MAN KAT. My niece's boyfriend already bought one of them, and I'm jealous. They live in Germany, which makes life easier; up to 7.5 tons, you don't pay per km like we do.
I still need to get an E+C, though. The european trailer shape fits nicely with some of my ideas.
In US you need special driving licence for 350/3500 trucks ?

 

Here in Poland they banned everything DIY . Stupid law . Previously, it was possible to register DIY cars . Now here is no room for hobbyists and amateur designers in the name of protecting the market. Stupid law because finally the Chinese will sell their cars anyway .

 

No. You only need a commercial driver's license (CDL) if the vehicle or combination is more than 11,793 Kg.

 

Here even 2500 lbs trucks exceed 3.5t GVW. And you need pay for every km of the "highways" via electronic control system .
What is really sick even RVs or veteran trucks with special plates are the same .
All right , I'm glad to not live in Japan .
