Hi Steve,
thanks for the compliment on my boat seen at Rooney Point. I would have been happy to show you the boat if you had come aboard. Maybe next time.
I was un my way home to Bribie Island after my coastal
passage up to Lizard Island and back.
As you know WilPower is a Bob Oram design, 10m waterline length by 4m width, allowing me access to 12m mono berths at
marinas. Its designed with wave piercing shaped bows. The simple sailing rig was always going to happen.
The roller furled headsail is 26.5 sq m designed by Doyle
sails Sunshine Coast Qld as a screecher with high cut clew to clear the
cabin and
sheets back level with the
mast (tabernacle is above the rear main bulkhead)
The 7.5m
mast drops forward to be level with the bows (to get under the Bribie Bridge).
I can do all the sailing using one
self tailing winch on the roof by standing on the
helm seat
head and chest through a large
hatch on the roof.
To lower & raise the mast I have to get up on the roof but the auto
helm keeps me slowly headed into the
wind for this. Takes 5-10 minutes to go down then up again for the Bridge.
The lack of
mainsail, boom and
rigging is a substantial cost saving.
I sail with one
motor running. I have crafted a
rudder but its not yet fitted. I hope then to be able to sail at 4kts in 10 kt breeze.
Typical motorsailing with apparent
wind to 60 degrees is achieved depending on wind gives extra 2nm/hr (eg 7.5 kts using 5.5 L/hr depending on sea conditions.
Typical motorsailing down (wind at 15kts) gives me a boat speed of 7.5 -9 kts using about 0.8L/nm. The fast
passage from Tin Can Bay to Bribie on saturday was with reactively no wind, mast down and with both motors at around 3900rpm gave boat speed of 12.5 -15kts using total less than 2l/nm over 9 hours.
Boat is built of DUFLEX (balsa core) took 14 months built in a shed at Burpengary and Ive been working to finish her during last 18/12 including my travels.Hope this satisfies your curiosity.
Happy
boating.
