Hey guys, I'm back.

Here's a new thread for discussing my newly designed Canadian ocean liners, MV*Newfoundland * and MV *Labrador* .

I based them off White Star Line's 1922 ocean liner RMS*Homeric* . They are about the same size (a bit bigger perhaps) but are diesel-powered with a 23-knot service speed, not bad for the cruise market I aim them for, as well as the occasional Altantic crossing.

Please evaluate my design and give me feedback.

**MV Newfoundland and MY Labrador, Canadian Express Ocean Liners. **

My two new ocean liners MV Newfoundland and her sister ship MV Labrador are 35,500-ton beauties of the sea that will service the ports of Québec City, Canada and Southampton, England. They will also offer numerous cruises during the winter, when the St. Lawrence freezes over. Their intended service is 23 knots with a capability to make 26 knots. As far as appearance goes, these two ladies will be very special ships, sporting two tall funnels that make them instantly distinguishable, a black-painted hull and white superstructure. The funnels are painted red with white top bands, and the finishing touch: a beautifully round stern. Passenger capacity is intended to be a modest 1000 people, due in part to modern regulations of safety and comfort. This allows unprecedented luxury for all passengers onboard these two floating palaces.

Gross Tonnage: approx. 35,450 gross tons

*grabs special spreadsheet*

- GRT would be... *throws numbers into spreadsheet*... 50240.

- Not 100% sure about my observation skills, but looking at the picture, I think that there would be a little bit more of the 12000 tons miscellaneous weights "above deck" than 500 tons.

- While this is not given in the SS notes and thus not mandatory, I personally like to stick to a higher figure for 1st class passengers than the 2nd class passengers in order to make a clear difference between the two classes. But that is how I work.

A quick question, how did you arrive at the 50,240 gross tonnage figure?

According to my research on the RMS Homeric (34,351 grt), and according to my dimensions, would assume that my ships would be a bit over 35,000 tons, which fits nicely with the 35,450 grt figure i came up with from my calcs.

Not to disprove your *special spreadsheet* but a 50,000 ton figure would require a ship bigger than the Olympics, even then closer to Imperator-size, and looking at the dimensions, seems a bit odd that the gross tonnage of my ships would be that high.

Just my opinion...

Also, I will rework the miscellaneous weight by puting, say perhaps, 1000 tons as "above deck" weight, put keeping the same total 12,000 tons miscellaneous weight.

Many thanks, RMSCANADA

For a Cargo Ship (for those interested):

## Quoted

To determine gross registered tonnage, make the following calculations:

1) Multiply "loading submergence" (listed below the weights table in the ship report) times ship's freeboard (listed under hull strength in the hull characteristics section.)

2) Add the result to normal displacement.

3) Multiply by 35, then divide the answer by 100. This is the gross registered tonnage for a typical cargo ship.

For and Ocean Liner:

## Quoted

When you compute gross registered tonnage, add 10-20 percent - this allows for the extensive superstructures of liners.

Displacement + (freeboard x loading submergence) / 2.5 is a handy formula to use, and adds 14 percent to the standard cargo ship figure.

The gross registered tonnage of a liner should be at least equal to her displacement, typically about 20 percent more (the Normandie had a registered tonnage close to twice her displacement).

The baseline gross registered tonnage of a liner built in 1900 or earlier should be 15 tons per cabin passenger and 5 tons per steerage passenger. Multiply this by the same formula as above for ships built later than 1900.

... and the mentioned formula is "multiply figure by 1 plus (date - 1900) / 25."

Well, here are the differing figures I came up with:

1. Using the formula for the cargo ship (+14 percent), I came up with a gross tonnage figure of**35,131** .

2. Using the +20% rule for gross tonnage for liners, I come up with a figure of**39,240** .

*The above figure I believe is better than originally calculated...I estimated "around 40,000 tons" when starting the design*

3. When comparing Normandie's gross tonnage to her displacement (79,280 vs. 71,300 tons -- a factor of 12 percent), on my ships it comes out to**36,624**.

--- If you average those three numbers, the figure comes out**36,998 tons** , nearly 37,000 ---

Personally, I think that the second figure is the most correct estimation for the gross tonnage of my vessels. Looking at various liners, I came up with Gross Tonnage restricting criteria:

- Based on her dimensions, she must be larger than Homeric (34,351 gt) but cannot be larger than the Olympic (45,324 gt).

- The mean of those two numbers is 39,387 gt, being only 39,387-39,240 = 147 tons off from the second gross tonnage figure.

To conclude this issue, I think the best gross tonnage estimate we can make is "around 40,000".

Also, a couple questions for those evaluating...

1. How many decks (practical) could I put on these liners?

2. Any ideas for public rooms? Anything to make them stand out from the competition?

3. How many lifeboats should I put?

*Anything else you guys want to add concerning my ships is welcome...
