A departure from the dhow-junk-lug of the previous experiments. This time a Bermuda rig with loose footed main.
WHY
Why the departure from dhow-junk-lug?
The balanced lug was the only experiment that placed the center of effort in a good place for a balance boat at all stages of a reefed sail. I could secure the tiller and the boat would stay on course., but the balanced lug required going forward to hoist or lower the spar and to reef, this was not easy in gusty winds. When single handed it took too much time away from the tiller resulting in wild boat swings. The junk and dhow were not an improvement and made single handed boat handling a chore.
OK, so can roller furling work on dhow, lug or junk? Not without a lot of complication.
SO
Both main and headsail on roller furler. Mast tabernacle with boom swivel/goose neck for raked boom.
Mast will be ex- 4 x 6 x 24ft cedar, with taper from mast tabernacle pivot to top 4 x 6 to 4 x 4 (3 1/2" x 5 1/2" to 3 1/2" x 3 1/2")
Boom will be ex- 4x4 x 12ft cedar, with taper from swivel to end 4 x 4 to 2 x2.
Mail sail alternates.
24ft mast 21ft luff, 23ft leech, 10ft foot for 105sf (9.75 square meter)
or
20ft mast 17ft luff, 20ft leech, 10ft foot, for 85sf (7.9 square meter)
The original Havsfidra mainsail was
25ft (7.62m) mast, 22ft (6.7) luff, 24ft (7.3m) leech, 9ft (2.75m) foot,
for 99sf (9.2 square meter)
Mast tabernacle and boom swivel (gooseneck)
Lamination for mast in progress. 24ft long laminated from (8) 1x6 x 12 cedar and (4) 1x4 x 12 cedar
Mast weight
1lb/lf 1x6; 24ft x 4 x 1lb = 96 lbs
0.69 lb/lf 1x4; 24ft x 2 x 0.69lb = 33 lbs
Cedar mast =129 lbs
Bolts/glue/fittings 20 lbs
Total mast weight 149 lbs estimate 150 lbs (70 kg)
Progressive Epoxy ESP 155
Mast head
Mast at tabernacle
Next make-up fore and aft stays, and shrouds. These will be cut approx 12" over length. Mast cannot be raised on the hard due to overhead branches, but will be installed in the tabernacle. Swageless eye at mast head will be installed on hard and swageless turnbuckle after raising mast after splash.
Also set eye bolt and nut at 1/3 mast height from top, for extra shrouds.
Estimated splash end of April May (to much paying work taking up my time)
Former tabernacle column and hatch cover removed.
Steel tabernacle 75 lbs (34 kg)
Tabernacle set. Bolts to follow.
Weight of tabernacle 25 lbs (11 kg)
Temporary bolts set. Final will be cast eye bolts
New forward hatch because the former tabernacle removal resulted in destruction of the former hatch.
Bomar 900 Series Molded Deck Hatch
Installed
At slip waiting for mast instal
Mast raised, upper and lower shrouds installed, temporary fore stay and back stay.
Stays and shrouds installed
Mast head revision with crane block. Head of Alado furler binds againat mast, the crane block will move Alado head further away from the mast. A longer eye bolt/eye nut required.
To be installed after haulout this fall, until then hanked on mainsail using the installed Alado stay.
Alado headsail roller furler installed
Former mainsail installed with lugs on 3/16" wire. The wire was installed for an Alado furler but the furler binds at the mast head. Revision to masthead will be this fall then furler installed in the spring.

February 2024
I see I have not updated the page. It was a rather busy 2023
Head sail on Alado furler was installed.
Main sail on Alado Furler was installed.
Boom gallows removed ()not a good idea.
Work for Spring 2024
Change double wire blocks at mast head fore and aft for fore and back stay which are also for furler, for single wire blocks.
The second block in the double was use for topping lift at aft and extra halyard at fore and add single blocks at mast head port and starboard for topping lift.
Change eye bolts at goose neck and bow sprit for jaw bolt for Alado furler and back and fore stay. (to gain 2" on furler.
And the usual bottom paint
