I'm pulling the stick in May when I haul out
. This is for a complete overhaul
, repaint and modifications. One of the things I am interested in doing is to do a major modification of the boom, including the following:
1. Since the Searunner
trimarans have the mast
located in the center cockpit
, all control lines are worked near the helm
. I want to install sheaves and line locks in the boom for the outhaul
and two or three jiffy reefs
, with the controls exiting at the gooseneck. I'm hoping some folks have interesting arrangements I might incorporate in my mod.
2. I have lazy jacks. I'm considering building one of those vee-shaped baskets of glassed foam or an aluminum
tube structure, around the boom, to contain the doused mainsail
. Moving the lazyjacks outboard
will help contain the sail more efficiently, allow me to install a permanent sail cover
that doesn't require slits for the lazy jacks, and will allow me to release and stow the lazy jacks forward at the root of the boom. Does anyone have a name for this type boom? I have seen a number of them locally, and they seem to perform exactly as I am hoping, yet keep the weight down.
3. The topping lift
will actually be a spare main or "skyhook", attaching at the aft end of the boom. A boom arch or structural bimini
will have hollows to support the boom when the topping lift
is released. The other main halyard
, plus staysail halyard
, roller furler genoa
and headstay genoa
halyards will all be internal. The two spinnaker
halyards will be on masthead blocks and external. There will be no pole lifts or other track devices.
4. The main sheet will either run under this basket structure, or through the interior
of the vee-base, with cut-outs to allow access.
5. The last consideration I have is for how to manage the waterfall that will occur when rain, falling down the face of the sail, is "guttered" to the chainplate area and onto the top of the hard dodger
. There seems to be no simple manner underway to keep the base of the mast
from being in a shower
mode during rainstorms. Any suggestions?
