Lets have a discussion on sealable walkway hatchs

The quick-acting steel doors used on navy ships do work like a champ. The spin type are easiest to use, but the lever type work nice too. All crew should be trained like religion on how to use them. In calm waters they can be left open so the crew can move about, but if you see rough seas in the forecast it's best to go into safety mode & keep them closed.

It's been a long time and I don't remember the Navy terms, but most ships have codes for designated sailing conditions.

e.g.

Code Red: Rough seas - hatches & portals closed, loose items stowed, life vests on.

Code Yellow: Moderate seas - loose items stored, life vests on

Code Green: We're at anchor in paradise and nothing could possibly go wrong. No need for a life vest unless you can't swim.

Of course, all crew should be well trained on how to rapidly secure all hatches, locate fire extinguishers, etc. They should know these drills like the back of their hands.

 

Safety drills, you hit the nail on the head there JT.

These are by far the most effective way for crews to become effective.

 

One way to avoid the midnight anchorage , thunderstorm imminent, up anchor and put to sea with the portholes open scenario, is to string the porthole dogs with light chain and lock them.

When unlocked PORT OPEN" , the key stays in the padlock. A quick view of the bridge key rack as you hustle out of the anchorage instantly spots the " missing " key...port side aft quest cabin..... and disaster is averted.

Guests can not open a port hole without asking for the key... ARE YOU CRAZY..I DONT CARE HOW HOT IT IS, WE ARE SAILING , YOU CANT OPEN THE PORT HOLE.....

the missing key.

Do you have any ideas what it cost to build a 120' Aluminum Sailing yacht? You are worried about cost of hatches? The rudder with steering gear alone will set you back $10,000. How about the keel, or the motors, or mast, or sails. The hull aluminum alone will be several $100,000. A naval architect is an absolute necessity. I am not sure what they would charge for a 120 boat, but a lot more than some hatches.

Dude your looking at a 5 million dollar boat before you launch it, not including electronics, or interior, and it won't be yacht finish at that price.

 

You can buy one for allot less then that ...lol I have already priced out the general aluminum cost form my normal supplier and I believe your pricing is again a bit on the high side of course that could depend on who you buy form or what alloys your getting I know I recently got some 7075-t6 for another build that the 12x4 sheets cost me more then 5086 8x24 sheets I get.

yes I am worried about the cost of everything like you said it cost money. I know it every part cost money trying not to get extravagant on all the little parts will help control my overall expense , for example just say your looking at buying a commercial made fixed porthole the first one you like cost $500 (just for a rough number) the next one you see and like does the same job but only cost $100 ..... now you need 10 portholes total so either 10x$500= $5000 OR 10x$100= $1000 now you can see this is just one part consider all the stuff required in a build this size then maybe you can understand how all the little things add up quicker then one or two big things or at least that is how I have always seen it, of course the cost of aluminum, mast , gear , electronics etc etc etc when not the topic of this thread

 

actual thinking about it the mahogany is going to cost me more then the aluminum...lol
