Ok the Dragon article "Flying boats...." was published and "Going for a Swim" will hit in 18 Also in issue 18 will be some material on two planets that have lots of water. So I thought a vehicles entry on some sailing ships/boats would be a good compliment.

That said, I dont know jack squat about sail boats.

I was hoping there were some members that could work up some sats and or rules on some fairly simple craft: A small 4-5 person craft, a cat or trimaran and a sloop. so that a referee could grab it out of the SFman and use it in an adventure.

Any sailors out there?
I might not be a dralasite, vrusk or yazirian but I do play one in Star Frontiers!

Well, I'm no sailor either - sorry. However, I have compiled a comprehensive list of all the watercraft that I have found stats for regarding Star Frontiers. Don't know if this will help at all, but I figure it can't really hurt. There is one vehicle listed below that I made up, the Personal Watersled. You'll notice that power armor is mentioned in my personal watersled description - that is because I have significantly altered the power armor(s) as presented in SFMan and this vehicle can be added to power armor if so desired in my SF universe. Of course, if that is not acceptible to whomever reads this simply delete that bit about power armor - if it does interest you and you'd like to see what I've done, let me know and I'll post or e-mail the specifics. Otherwise I believe that all the vehicles listed below have been gleened from multiple sources. I have descriptions all compiled together as well if those are needed, but for the sake of space I figured I'd not do that unless someone actually needed them.

Most of you will probaly notice that a couple categories have been omitted from the chart below (m/turn and accl/decel). The reason for this was that not all the sources had those listings and I frankly haven't gotten around to filling in the blanks yet - so for now I'm just omitting them and will figure that information out at a later date if I should ever have a need to do so.

Personal Watersled: This is a single-person underwater form of conveyance which is not enclosed, leaving the user exposed to the fluid environment. It can transport one person (or a person wearing power armor) through the water (surface or underwater) at a top speed of 10kph, cruise speed of 5kph. The rider simply lies on top of the board, grasps the handles and is propelled forward by twin power fans. It takes two (one for each motor) 20SEU power clips to power (or can be plugged into a power backpack or beltpack) and consumes 2SEU’s per hour. Weighs 5kg.

SAILING 

The speed of a sailboat depends on many factors, including, but not limited to wind speed, water conditions, and hull drag. Obviously the more wind, the faster the boat will go, however, each boat has what is called a "hull speed", the absolute maximum speed the boat will travel. The rougher the seas, the more the boat will bounce, and as a result, will be slowed.  Also, a smooth hull will go faster than one with a lot of sea junk stuck to it. Catamarans and Trimarans accelerate to top speed faster than monohulls of the same length because they spread their weight and have less drag. The trade off is that monohulls make better headway when heading into the wind (tacking) than either catamarans and trimarans.
The higher the wind speed, the rougher the seas usually are.  So you have one force trying to speed you up, and one trying to slow you down.

Hull speed (for a displacement hull) is a mathematical formula based on the length of the waterline. Hull Speed (in knots) = 1.34 times the square root of the waterline in feet. 1 mph = roughly 0.869 knots.


The difference between length and waterline length will vary drastically depending on the design of a particular boat. Since it all depends on many outside factors, for game purposes, an average speed of sailing vessels with a good wind is 20 mph.

 Waterline of Boat Average Speed (knots)Average Speed (mph)
   
 4 ft. 2.50 knots 
 9 ft. 4.00 knots 
 16 ft. 5.50 knots 
 25 ft. 7.00 knots 
 36 ft. 8.00 knots 
 49 ft. 9.50 knots 
 64 ft. 11.0 knots 
 81 ft. 12.0 knots 
 100 ft. 13.5 knots  
 121 ft. 15.0 knots 
 144 ft. 16.0 knots 
 169 ft. 17.5 knots20 mph 
 196 ft. 19.0 knots 


Wind Speed

As the force of the wind will affect a sailboat's speed, one simple way to determine its effect is to use a system of windspeed multipliers to a sailboat's hull speed.

WINDSPEED/HULLSPEED MULTIPLIER*

00 - 09 mph / unable to sail
10 - 20 mph / hullspeed x 1.0
21 - 25 mph / hullspeed x 1.5
26 - 30 mph / hullspeed x 2.0
31 - XX mph / unable to sail

WIND DIRECTION (1d10) 

1&2 = North
3 = Northeast
4 = Northwest
5 = East
6 = West
7 = South
8 = Southeast
9&0 = Southwest

*A sailboat moving against the wind direction (tacking) moves at half normal speed.

Thanks Capt Raggs that's exactly the kind of information I was hoping for.
I might not be a dralasite, vrusk or yazirian but I do play one in Star Frontiers!

When the course is laid and the anchor's weighed 
A sailor's blood begins racing 
With our hearts unbound and our flag unfurled 
We're under way and off to see the world!

Do'knots Captain Rags, he's right on the money!
:-)

Hey, do'knots it man.

To knot, or knot to knot. That is the question.

Two knots walk in the bar... one says, "I see you got frayed ends mate." The other replies, "I'm a frayed knot man."

Yazirian anti-hair knot = Norelco Speedrazor TZZ.A from Issue 9.

Ask knot what the Frontier can do for you, ask what you can do...um...for uh... Cool

Don Knots? Money mouth

You might try talking to Art Eaton on starfrontiers.org.  As a former Navy sailor and contractor, he could probably give you any information you need.
