17,4m Motor Yacht Concept Design

This is a new concept design a 17,4m Motor Yacht

Lenght 17,4m
Breath 4,5m
Persons 6-10

 

I think the steps with the curved fronts are an accident waiting to happen, especially the ones on the stern. Too easy to mis-step, especially with any boat motion. Even with a square front, the curved steps on the stern are going to be difficult to negotiate carrying provisions, luggage, spares, etc.

 

It could be just the perspective, but it looks like the bow is higher than the stern. Perhaps a bit more sheer.

What will the boat be used for ? In southern regions the sun is so intense that guests never venture out of the shade. A shaded... "pull out" awning arrangement for the aft deck would be nice .

How will you store a small rib or tender ?

A boat that size would carry 6 sausage fenders ....any deck gear storage ?

For anchor handling I prefer a drop from the stem Bruce anchor . The anchor you have drawn will make it difficult to handle the bow mooring when going stern too.

 

Looks like a yacht to me. I agree the stairs are dangerous because even straight ones with two handrails are bad enough in a seaway. I like the Bruce stowage hugging the centerline hawse pipe and stem. Yes fenders in lifeline stowage usually forward because nobody goes up there underway anyway. Lifejacket locker somewhere on deck usually and probably a float off solid raft or an inflatable raft for charter use. Full awning that's really well designed and not an afterthought.

 

I dont know what the interior layout is but why not bring the morning sun light into the aft cabin with windows built into the stern . Light makes small boats feel big.

 

Smoke and mirrors help too.

 

Same things again...

Propeller clearances are too small. Bottom shape at stern should be redesigned to fit actual propeller; this prop is just too small.

Transom is submersed for half of max draft - is it semi-planing boat?

Where is mast for navigation lights, radar, etc.?

 

At that length (and equipped with a skeg) I would seriously consider fitting a stern thruster for maneuvering in harbour.

Also, hand railing at those stairs is definitely too far for normal usage / less alone bad weather.

Where are the ropes stored? I see no openings on the bow.

 

Maybe a semi-tunnel stern is what is needed, giving a much larger prop on same draft. Yes, where is the necessary 'antenna farm'?

 

Sorry but I have only now time to respond


To enter and exit with vessel that will be a gangway.

the anchor it's look better than I am design

When the future owner decided to build this vessel then I am take care a size a propeller

The bow and stern is almost on this same high.

When the future owner decided to build this vessel then I am take care a size a propeller

navigation lights and radar will be on construction of the tubes at the stern abow flydeck

That will be a deck store on bow

The interior owner will be built and designed by him self but this vessel is designed for 6 to 10 people

Whole extra equipment the owner do it by himself
