Wide Beam vs Narrow Beam

[wolfenzee]

As a little kid I remember looking at my father's porn magazines (like Yachting) and porn books (like the Proper Yacht) etc....

I own a Perry Designed Islander 28, 1976 with a dark blue hull. We love this boat- routinely get compliments on her lines. It's been a privilege to just hear the thoughts of Mr. Perry on this topic. He's one of our boat world heroes! Never miss his columns in the sail mags...

You mean her stern is pointed at your bow?

If you are that concerned about safety, go to "Sail Calculator."
This way you can see ALL the inportant data.

Aventura:
What a nice thing to say, thanks.

Looks surprisingly similar to a 26'er I have seen somewhere ...

this link give lots of different types of calculators
Capsize Formula

here is another that also has production boats so you don't need to find out your specs, which also give an explanation of what all the ratios mean
Sail Calculator Pro v3.53 - 2000+ boats

don't rely on this info too heavily it is best for comparative purposes
I find these ratios very informative and they make me feel alot better about my boat.
My "angle of of vanishing stably" is 184 which I guess means I have to go 4 degrees past completely upside down before I come up on the other side?

[S&S]

Ours is 48' x 12'x 8' . If I were looking, I'd like 10' more length, same beam and a foot more draft.

On a beamy boat, sure you'll get more righting arm, until it goes negative. Remember the Fastnet?

A higher righting force means more acceleration as the boat rolls. If you sail in smooth water who cares, but it can get uncomfortable quick as the waves build.

Dorade was able to average 1.88 x sqrt of LWL. across the Atlantic.Why? She is really skinny.
52' x 10' x 8'6 IIRC.

So put me on the long, skinny and deep side of this discussion. I'm not a big fan of primarily "form stabilized" boats.

I am an Alberg junky. Does that say anything.

Fairhaven Newspaper in a vault in the library, I read this in 1982. Held the original old paper from the time.

" Capt Slocomb was run down by a steamer at night "

Go to the library and look it up like I did. How many historians looked there.

They had proof to back it up in the news story. He never ran with lights.

One hundred posts later and not a mention.
My toy boat has an lwl of 20 feet but the waterline beam is almost full width of the o/a beam which is 9 feet. Not far off 2:1 and this boat steers like a pig.
So the fact that directional stability hasn't been mentioned means that it shouldn't be part of the equation?

My only point was about the "Spray"

Doing research in the 1982 I came upon the newspaper in Fairhaven Mass.

Makes sense that he could have been run down at night Slocum never had any lights.

While this is alive again. Any thoughts on Brent Swain 36, looking at one for sale. Anyone have experience on one?

A cruising friend owned one many years ago and he sailed it down from Vancouver to Mexico and on to New Zealand. Damn thing actually sailed better than it should have, these are home made boats so it will depend on the quality of the build but the design is more than adequate.
