NEW COURSE COMING SOON – WORKBOAT STABILITY!
WHO NEEDS THE MCA SMALL CRAFT STABILITY COURSE?
The MCA Approved One-day Small Craft Stability Course was originally launched to satisfy the Workboat and Pilot Boat Code of Practice, however the concepts are equally useful to skippers and mates of all small craft (sail yachts, motor yachts, fishing vessels, rescue craft, pilot boats and workboats). We recommend this course to the following;
- Skippers of any workboat which is required to carry a stability book (mandatory)
- Skippers of workboats operating more than 60 miles from a safe haven (mandatory)
- Skippers of workboats carrying more than 1 tonne cargo (mandatory)
- Skipper of workboat fitted with a crane or dredging gear (mandatory)
- Skippers of workboats operating in ares prone to icing, i.e. Northern European winter (mandatory)
- Masters of sea going pilot boats (mandatory)
- RYA/MCA Yachtmaster Offshore candidates (recommended)
- STCW Master 200 candidates (strongly recommended)
- STCW OOW 3000 candidates (strongly recommended)
- MCA Fishing Class 1 or 2 COC candidates (recommended)
- Skippers of sea going fishing vessels (strongly recommended)
- RYA Cruising Instructors (recommended)
- RYA Yachtmaster Instructors (strongly recommended)
- RYA Navigation Instructors (strongly recommended)

WHAT IS COVERED ON THE MCA SMALL CRAFT WORKBOAT STABILITY COURSE?
This one-day classroom course includes plenty practical demonstrations and exercises. While this is traditionally a mathematical/scientific subject our Instructor will assume you have no formal stability training, he will keep formulas to an absolute minimum and focus on ensuring you leave with a working knowledge of small craft stability. The course content is;
- General terms in use
- General Principles of Transverse Stability
- Location of CoG, K, M, CoB
- Rolling and shift of CoB
- Theory of Moments, Righting levers, List & heel
- Equilibriums
- Adding, removing and shifting weights
- Simple calculation of transverse stability and effects on draft
- General understanding of change of trim
- Trimming moments
- Longitudinal Metacentre & LCF
- Importance of monitoring of any changes, regular checks
- The Stability Booklet
- Stiff and tender vessels
- Use of cranes and shift of CoG
- Free Surface Effect
- Tanks
- Consumption of fuel and water
- Water on deck
- Critical KG calculations (Transverse Stability)
- Inclining Test
- Deck edge Immersion
- Catamaran stability
- Risks associated with Tug and Tow
- Risks associated with deck cargoes
- Wind & Ice accretion Effects

INCLUDED IN THE COURSE?
- Day of training (& assessment)
- MCA Certification
- CT Stability Course Handbook
- Motor, Sail & Fishing Vessel Stability Notes
- Use of model boats, test tanks etc.
- Tea and Coffee
- Free (on street) parking
NOT INCLUDED IN COURSE?

WHAT IS THE TEACHING RATIO FOR MCA WORKBOAT STABILITY?
We run this course with a maximum of 12 students per Instructor. Each pair of students has use of their own model boat, weights and water tank for the duration of the day to run the various scenarios themselves.
