CD-3.5 Hinged Sailgate: SP-375:
Original cast aluminum hinged assembly has sliding SS pin which, when lifted allows the
1 1/2" gate section to swing open. Designed to be mounted above the height of the
stacked mainsail slides, the sail is loaded by putting the lowest slide in first.
Cast in 356 Aluminum with clear anodized finish. |
|
Sailgate Stop: K-10424:
SS internal sliding gate stop assembly has spring plunger pin and slides in the mainsail
track. Slide is 3/4" wide x 2 1/2" long. As the slide is longer than the gate
cut-out it is held captive in the track and is locked in front of the gate cut-out by a
hole drilled in the track there. Pulling the SS plunger allows you to slide the stop
down and open the gate. Designed to be mounted just above the Gooseneck Bracket, the sail
is loaded by putting the top slide in first, and sliding the stop up to cover the gate
after the last (lowest) slide is in. RR 73-97
|
|
| Although it adds a few inches to the height of the
sail stack, this system offers numerous advantages over the original hinged sailgate in
that it is totally captive (can't be lost), unobtrusive, and never needs replacement.
Most importantly it simplifies sail raising and lowering, and especially reefing, as the
sail slides have no obstacles as they slide up and down the mast.
Please NOTE: Although it offers a nice choice on a new spar this is a difficult
item to refit in place of the original hinged unit, as it requires that the original
cut-out be filled in carefully. |
