ABL-11a a. Demonstrate your knowledge of personal safety equipment needed while cleaning, maintaining or repairing your vessel.
Safety Equipment • Safety goggles / face shield • Protective clothing • Hard hat • Dust mask • Safety harness • Life jacket • Always work in pairs!
Other Issues • Some jobs are adult only (bottom paint, etc.) • Working on the mast, those below wear hard hats • Not just the lightest person on the mast, best to do the job • Working in the water requires an observer • Youth doing the actual work may be less efficient, but much more learning takes place
ABL-11b b. Know the names, uses, sizes, and proper care of the common hand tools used by your ship.
Pliers • What do these varieties do?
Wrenches • Many kinds (what kinds?) • Select for the need • Metric or SAE? • Put them back in order
Screwdrivers • Identify the types • Some sized SAE • Some (Phillips) by number • Some metric
Hammers Plus • What kind? • Why different ones? • What would you use a hacksaw for? • How would you use a rigging knife? • Does it have an emergencyuse?
Power Tools • G2SS 2015 rules • 14 & up – paint roller/sprayer, Dremel tool, screwdriver, hand sander, etc. Drills? • 16 & up – lawnmowers, line trimmers, edgers, leaf blowers, hedge trimmers, belt sanders, pressure washers • 18 & up – power saws (any kind), routers, chain saws, log splitters, wood chippers
Teaching • Do not assume a youth knows how to use a tool • Tell them how, then monitor their use until you are satisfied they are safe and effective
Working at Height • Up to 4 feet – OK • Over 14 – up to six feet following ladder standards • Over 18 – scaffolds or open platforms with fall protection • Does not address bosun chairs
ABL-11c c. Identify and explain the use of the following: thimble, shackle, turnbuckle, pelican hook, and other ship's hardware and fittings commonly used aboard your ship's vessels. Describe how each is sized.
Pelican Hook • Overcenter & latch • Upper hook sized by length • Lower hook by wire diameter • Used on lifelines • Some other uses • Bottom hook quick release
Shackle • Clevis shackle – mainsail or anchor attachment • Sized by clevis pin • Swivel shackle and twist shackle are varieties • Snap shackle – jib attachmentor other quick release job • Sized by inner diameters
Thimble • Rope thimbles – anchorline, other wear points • Sized by line size • Can turn a sharper bendthan a wire rope • Wire thimbles – runningand standing rigging • Sized by wire size • Loop is larger for the diameter
Turnbuckle • Attaches standing rigging to deck and chainplates • One thread is RH, one LH • Twist the buckle to tighten / loosen • Insure cotter pins / screws installedto prevent unwinding • Sized by bolt size and body length
ABL-11d d. Demonstrate proper surface and coating preparation, coating techniques, care of stored coatings, and cleaning of brushes and tools used to maintain surfaces on your ship's vessel.
Surface Preparation • Remove old paint / varnish if needed • Sand smooth and clean • Use sealer on new wood • Surfacing compound to fill in any flaws • Primer to bond the paint • Apply coat(s) of paint / varnish • Agitate paint well, not varnish • Apply on a clear day, 60°-85°
Storage • Clean lids and cans • Seal lids tight with rubber mallet • Paint gets old in a year or two, don't use old • Do NOT store paint (or other flammables) on a boat • Find an outdoor locker or garage • Well ventilated
Cleanup • Water-based - • Rollers can be cleaned with hose nozzle • Until NO paint comes off • Brushes – hose or bucket – NO paint coming • Oil-based - • Thinner – takes time – no paint coming • Brushes - • Hang up by handles • Never leave standing on bristles
ABL-11e e. Explain techniques used for the maintenance, protection, and repair of hulls and decks on your ship's vessel.
Fiberglass Repair • Recommend doing this with Sunfish and similar boats, they often take a beating • If every boat available is in good shape, this can be done with plywood or other materials for practice • Buy fiberglass patch kit at hardware store • Caution: Activator must be put in glass / metal cup and used within very few minutes
Fiberglass Repair (2) • Prepare the hole – sand a clean surface 2” out • Prepare the fiberglass – pre-cut your patches to match hole and / or larger area, • Mix your resin • Apply a coat to hull as an anchor, dry tacky • Soak first fiberglass layer, apply • Smooth with broad putty knife, outward • Allow to cure • Repeat as required
Fiberglass Repair (3) • Finish with layer of resin, cure • Sand down and feather edges • Use 240 grit, then 400 grit wet-or-dry sandpaper • Let cure • Paint as needed
