Soling 50 (RC Model)

Soling 50 (RC Model) is a 4 ′ 2 ″ / 1.3 m monohull sailboat designed by John & Laurie Converse/J. Lange and built by Vortex Model Engineering (USA) starting in 1970.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The SOLING 50 is sanctioned by the national American Model Yacht Association and has active fleets racing in California, Florida, Michigan and Texas.

​Description

 

FOR RACING IN THE AMERICAN MODEL YACHT ASSOCIATION – SOLING-50 CLASS.

The Soling-50 is a radio controlled model of the Olympic class Soling which is a 27 foot, 3-man keel boat designed by Jan Herman Lingle of Olso, Norway in 1964.  The Soling-50 is an AMYA one design class boat.  It is a great starter boat, easily transported with removable keel and detachable sail rig weighing a minimum of 17 lbs.  Radio equipment is an inexpensive 2 or 3 channel surface radio.  The soling-50 fleet offers close and competitive sailing in moderate and stiff winds.

. Reason: added P.S
might give you a good idea of what the double arm setup should be like. Just a hunch, but the arm needs to aligned with the servo spline a particular way and perhaps it was incorrectly aligned when you first tried it out. Also make sure the rotation direction is the correct, mayhaps the previous owner has his servo reverse switch flicked.

Otherwise post a good picture of the set up you have or draw out a schematic of what you see there if a picture won't work. You should be able to work out the correct arm swing without the radio first. Just turn the servo arm by hand.

  1. SOLING 50 (RC MODEL) - sailboatdata

    Designed to determine if a boat has blue water capability. The CSF compares beam with displacement since excess beam contributes to capsize and heavy displacement reduces capsize vulnerability. The boat is better suited for ocean passages (vs coastal cruising) if the result of the calculation is 2.0 or less. The lower the better. CSF = Beam ...

  5. All things Soling 50 home thread - Let's see your boat! - RC ...

    I won my Vortex Soling 50 on ebay, a barely used boat that was all original. Dacron Sails, travelers, boomless jib. When I showed up at the seller's house to pick up the boat, there was a full size Soling in his driveway!

  6. Bigg's Soling Build and Refit - RC Groups

    Setting up your Soling is not a one time thing. As with all rc sailing, the boat should be adjusted for the conditions at the lake. Some guidelines for a basic setup are as follows: 1. With sheets fully closed (close hull), the tip of the boom should point to the port or starboard corner of the transom.
