I can believe in the safety of the boats on this list, but comfort? The Contessa 26 is on the list. "Bika," a Contessa 26, is currently in our harbor on the Mississippi. (Google BIKA and read their web site.) The owners have flown back to Norway to earn some boat bucks so they can continue. They have lived on this boat since May 2005, and I don't understand how! Two people in a sailbaot that measures 25 feet six inches by 7 feet six inches is not my idea of comfort! I'd much rather live on an Island Packet 465CC. But maybe that's because it's the only sailboat I've ever been on with over 7 foot headroom! It's too new to have made that list.

I'd be curious to hear of others' opinions regarding what they consider bluewater multihulls. Maybe a new thread would be better for that question, but since we're talking bluewater here...

After reading many opinions about boats here, I decided I had to approach this whole thing a touch more analytically and created a Cruising Boat Stats spreadsheet.

With respect for everyone's opinions, when it comes to offshore cruising there are some stats that can really help you understand the boat's performance characteristics.
I expanded on the data on another thread at Sailnet, and listed all the boats' basic parameters, then threw several calculations at them.
I have not checked to see if all of Mahina's boats are on here, that will take some time. But there are a lot in there!

By using Ted Brewer's and these sources I dropped in the most relevant/available formulas.
Design Basics
Sailboat Design and Stability
Ted Brewer Yacht Design

The only thing missing in the data is the ballast, which you should add for your favorite boat.

Cruising Boat Spreadsheet
This sheet can be edited by anyone.
Try not to blow away the formulas.
Insert a new row
Autofill the row based on row above (this brings down the formulas)

If this is inappropriate I can remove.
Let me know what you think!

Has anyone considered Contessa 32 or Sadler 32. Contessas are numerous in the UK, Sadlers as well. Quite a few Contessas in NA and only a few Sadlers.

Here are some sites referencing contessas.

Contessas are fairly well regarded as bluewater capable pocket cruisers... The reason Sadlers are probably a bit rare here is that they generally didn't come over from England, since people could buy the Contessas made up in Canada for less money and have the boat come a much shorter distance.

BTW, Contessa 32s are still in limited production in England AFAIK.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I think the Westerly line could use an update:

Westerly 26 36 ENG Not flashy, but fairly well built boats.

In particular, the

Sealord 39
Oceanlord 41
Ocean 43
Oceanmaster 48
Ocean 49

Should likely be there. For details:

Westerly Owners Association

Did anyone look at the spreadsheet I put up?
Is it useful to help find a cruising boat based on the Mahina, Ted Brewer and Johns Boat Stuff lists?

The one piece of data I haven't been able to figure out yet is Roll Acceleration, which requires Roll Angle. Where does one get that data on boats?

(7) ROLL ACCELERATION = (6.28/T)^2*RADIUS*(ROLL ANGLE*3.14/180)/32.2 Units of G's, where "T" is the ROLL PERIOD. From Marchaj's book, SEAWORTHINESS, THE FORGOTTEN FACTOR, chapter 4, "Boat Motions in a Seaway". The author presents a graph of roll acceleration Vs four physiological states; Imperceptible, Tolerable, Threshold of Malaise, and Intolerable. Malaise starts at .1 G, Intolerable begins at .18 G. Spending much time under these levels of acceleration reduces physical effectiveness and decision making ability through sleep deprivation. The radius term assumes an off center berth located 1.5 feet inboard from the maximum beam. The roll angle is 10 degrees. G levels above .06 are considered undesirable for offshore cruising conditions. Several light weight, large beam designs have G levels above .4, definitely "intolerable" for any length of time. The ROLL PERIOD is calculated from the equation: T = 6.28*( I /(82.43*LWL*(.82*beam)^3))^.5 , and has dimensions of seconds. The roll period is based on the moment of inertia, I, waterline length, and beam. The term (.82*beam) has been substituted for the waterline beam due to lack of data. The general rule of thumb is that boats with periods less than 4 seconds are stiff and periods greater than 8 seconds are tender. The MOMENT OF INERTIA is calculated from the equation: I = (disp^1.744 )/35.5 , and has dimensions of lb.ft.^2. An empirical term used by SNAME for analysis of the 1987 Fastnet race. The moment of inertia is very sensitive to the distance items are from the center of gravity. A heavy rig can greatly increase I, with little impact on displacement.

Mark, I for one have spent hours going over your spreadsheet. It's a great help for comparing boats. Thanks so much for sharing it with us.
