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

17. 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

18. 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

19. 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

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

26. 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

27. 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
