According   to   Triad   Trailers,   one   should   first   load   a   trailer   by   placing   most   of   the   weight   (80-­‐
90%)   on   the   keel   as   it   sits   in   the   trailer’s   keel   tray.      Then   screw   each   individual   hull   support   up   to   
the   hull   just   until   light   contact   is   made.      Do   this   for   each   of   the   six   individual   hull   support   stands   
(on   the   Triad   Trailer).      After   all   six   stands   are   touching   the   hull   release   the   lifting   straps   so   the   
boat   is   now   mostly   on   the   keel   with   the   hull   support   stands   preventing   the   boat   from   tipping   side   
to   side.      Adjust   each   hull   support   stand   upwards   towards   the   hull   to   a   point   where   you   are   only   
able   to   spin   the   carpeted   top   on   the   hull   with   a   good   amount   of   force.      After   each   hull   support   
stand   is   properly   adjusted   tighten   the   set   screw   on   each   of   the   6   hull   supports.      This   set   screw   
prevents   the   wing   nut   handle   from   vibrating   down   during   travel.            

Be   particularly   careful   when   strapping   a   boat   down   to   the   trailer.      It’s   not   uncommon   at   regatta   
venues   to   see   boats   quickly   hauled   and   lowered   onto   their   trailers,   with   little   time   to   get   the   boat   
aligned   and   sitting   properly   on   the   poppets,   then   strapped   down   hard   onto   the   trailer   with   
powerful   ratcheting   webbing   straps   and   then   driven   off.      In   short,   the   hull   is   being   pulled   down   
hard   on   top   of   the   keel/sump   and   in   a   very   short   period   of   time   is   potentially   subjected   to   
excessive   stresses   and   strains   on   the   entire   hull/keel/sump   structure.      If   you   have   a   bow-­‐stop   on   
the   trailer,   use   shorter   strap   runs   (running   nearly   vertical)   over   the   boat   rather   than   long   
diagonal   straps   through   the   bow   and   stern   rails.      This   reduces   the   possibility   of   trailer   flex   
contributing   to   any   excess   strain.   

Docking   &   Mooring

   -­‐   care   should   be   taken   to   avoid   mooring   or   docking   your   boat   in   locations   that   

can   result   in   the   keel   being   occasionally   imbedded   in   the   mud/sand/silt   when   at   low   tide   or   low   
water.         A   combination   of   the   keel   bulb   imbedded   with   any   sort   of   wave   action   against   the   hull   
can   cause   undue   stress   to   the   hull   and   structure.      The   same   is   true   for   boats   that   use   special   
dockside   hoisting   systems   to   hoist   the   hull   out   of   the   water,   while   the   keel   remains   underwater   
and   unsupported.            

Maintenance   Considerations   

Care   should   be   taken   to   avoid   having   standing   water   in   the   bilge.      Not   only   does   standing   water   
accelerate   corrosion   of   wiring,   fasteners   and   keel   bolts   over   time,   it   ruins   floor   boards   and   
interior   woodwork.      As   the   gelcoat/   paint   ages   in   the   bilge   area,   bilge   water   can   eventually   seep   
into   the   fiberglass   laminate   by   way   of   pin   holes   in   the   gelcoat   and   weaken   the   fiberglass   laminate   
structure.   The   process   of   hydrolysis   can   be   initiated   in   the   fiberglass   laminate   anytime   there   is   
ingress   through   cracks   in   the   paint/gelcoat   in   the   bilge.      The   process   of   hydrolysis   is   persistent   
and   invisible-­‐   it's   water   that   chemically   degrades   the   quality   and   strength   of   the   laminate   over   
time.      Bilges   (all   areas   under   the   floorboards,   not   just   the   centerline   bilge)   should   be   cleaned   
thoroughly   once   per   year   and   then   every   five   years   recoated   with   fresh   gelcoat   or   epoxy   paint   to   
ensure   proper   protection.      In   northern   climates,   water   turns   to   ice   in   the   winter.      If   moisture   gets   
into   the   laminate   and   freezes,   this   can   rapidly   accelerate   deterioration   in   the   laminate.      The   New   
Hampshire   Materials   Testing   Labs   website   (www.nhml.com)   has   an   informative   article   on   
hydrolysis,   see   Newsletter   of   May   1,   2006.         

In   any   cored   hull,   take   special   care   to   avoid   having   any   fasteners   penetrate   the   inner   hull   
laminate.      Water   in   the   bilge   area   can   easily   weep   through   the   fastener   into   the   laminate   and   
cause   core   damage.      If   you   need   to   secure   a   fitting   or   wire   tie   to   the   hull,   the   best   fastening   
method   is   to   glue   a   piece   of   epoxy   coated   marine   ply   to   the   hull   and   then   fasten   into   the   ply.   

A   growing   trend   amongst   active   one-­‐design   racers   is   to   use   a   dehumidifier   to   keep   the   inside   of   
the   boat   dry.      This   extra   step   not   only   keeps   the   boat   a   little   lighter,   but   helps   everything   from   
wiring,   to   woodwork,   to   sails,   last   longer.
