Definitions
- the unique bow rudder keeps the top heavy ship stable when sailing with outriggers pulled in and allows the ship to turn on a dime without listing.
- This design provides the advantages of a trihull with large cabins and resistance to rolling in side swells with the advantage of a good length to width ratio of a standard hull for less drag and better maunerverability.
- a trimeran hull has more drag.

Abstract
The CONVERTABLE OUTRIGGER TRIMIRAN allows a trihull cofiguration for anchoring with outriggers extended to stabilize the top heavy and spacious cabin deck and with outriggers withdrawn has a narrow hull for sailing manuverability and fuel economy. The bow V rudder provides torque for stability and steering when sailing with outriggers withdrawn. The bow V rudder also allows the ship to turn on a dime.
Description
- In attempting to design a somewhat normal hulled ship with large cabins I came up with this design which allows a 16 foot wide hull at the waterline to have a 32 foot wide main deck which allows 14 foot wide cabins on both sides of a central corridor on a smaller than normal yaucht.
- The unique bow rudder keeps the top heavy ship stable when sailing with outriggers pulled in and allows the ship to turn on a dime without listing.
- This design provides the advantages of a trihull with large cabins and resistance to rolling in side swells with the advantage of a good length to width ratio of a standard hull for less drag and better maunerverability. A trimeran hull has more drag.
- The bow V rudder keeps the ship from listing when turning and gives sure response to keep the ship stable when sailing with outriggers withdrawn. The V rudder not just stableizes but allows the ship to turn on a dime without listing.
-
FIG. 1 shows three views of the basic hull and maindeck with outriggers withdrawn and extended and the bow V rudder. -
FIG. 2 shows the outriggers with hydralics which when withdrawn or extended will not tend to weep. -
FIG. 3 shows starboard outrigger with hydralics exended and attachment points curved about the hindge to limit seepage into the cabin level through the deck. -
FIG. 4 shows bow rudder configurations with turning hydralics. -
FIG. 5 shows water pressures in a starboard turn from the bow perspective effecting turning and a righting force. - The outriggers
FIG. 1 1 when extended 2 make a trimarin hull which makes the topheavy ship stable when anchored or moving slow. This allows verywide cabins 3 with a narrow crusing hull. The hydralic attachment plates FIG.2 5 are curved about thehindges 4 allowing little seepage to enter the cabin level through slots in the deck. - The hydralics are extended when the outriggers are withdrawn limiting hydralic weeping and as the center of boyancy of the outriggers when extended 6 is outside the hindges there is little pull on the hydralic rods also limiting weeping. The bow rudder
FIG. 5 10 when put to starboard creates not only steering thrust but creates torque 9 to keep the ship from listing. Very tight turns are possible. This V rudder also makes for responsive correction to listing when sailing with outriggers withdrawn.
Claims (2)
1. A system of extending outriggers from a basic ships hull so as to allow for a main deck wider than the hull thus allowing large cabins.
a system of hydralics to effect the extension of the outriggers which are arranged to limit weeping and seepage of water into the cabin level.
2. An arrangement of a V bow rudder which stabilizes the top heavy cabin deck when the outriggers are withdrawn and moving and allows the ship to turn on a dime.
