Preassembly Rigging Parts Check/Tools
Tools You Will Need
MKIV Furlers are shipped with 3M 5200
adhesive. Use adhesives on dry connectors
and foils using the special injection system
described in the assembly section. Parts
may immediately be exposed to rain. Cure
is best at 70F (22C) with 50% humidity.
Do not apply at temperatures below 40F
(5C) and above 100F (38C).
Although adhesive has not cured it will
remain in place on foil joints whether
they are left on the ground or raised up
on boat. Foils can be raised immediately
after assembly and sails fitted.
Note: A small amount of adhesive may
bulge out of injection ports. If possible
let system sit for a couple days before
sailing. If adhesive gets on sails remove
using acetone. For faster-curing adhesive,
purchase 4200 Fast Cure.
Note: Damaged foils can be repaired.
Use a hand-held propane torch to heat
joints until foils can be pulled apart.

*Requires some beveling of bottom edge of deck hole to provide a good fit. Alternatively a smaller hole may be used to fashion a socket in deck to conform
to ball shape. This may improve appearance and reduce amount of water that enters. A 4 1 / 2 " (115 mm) hole saw may also be used if no beveling is desired.
