Padeyes

I decided to weld to the deck a number of padeys to be used as shackle, block attachment ad for safety harness connection when working at the mast, staysail, bowsprit, wind vane and so on.

We made them with a 10mm baseplate and a 10mm round of alu.





Staysail padeye and blocks dry fit





This is the aft double block that will bring the sheets to the winch with the proper angle



Spinnaker guy and sheet blocks









Mainsail blocks and spinlock






uhmmm, the was an error.  We will drill new holes!







Forepeak and WTB

Finally we had to complete the closures to the forepeak.

This includes the deck hatch to anchor locker and the watertight door on the bulkhead

We choose a strong, simple and reliable closure method, I think (?!)















Head Sails Rails

The rails for the genoa and stay sail were a real suffering. There are too many holes on the deck!
I wish I had done it in a different way, but here we are.

Urethane and duralac an go!


First whe had to drill the 10mm reinforcement plate placed under the deck.















Then create the space for the nuts in the foam



Duralac and urethane



Bolting

Winches

It is now time to turn this boat into a real sail boat.

Placing the winch posed a new issue. as usual when a new step arrives, new questions and doubt arise.
The is not much experienced people around well informed on aluminium construction.

Here the question again was sealing the through deck holes and galvanic insulation.
It was complicated by the fact that the winches mechanism are in bronze.  Bronze should be very carefully isolated from aluminum. The external body is aluminium that poses no problems except for the two motorized winches near the mast.

So agin the choice was: Urethane for sealant, Duralac on bolts, and teflon to insulate different metals.

More attention had to be given to the positioning of the winch gear an respect of the 8 deg angle of attack for ropes.

Despite the fact that we did all the calculations when preparing the position of winches, placing of reinforcement plate, and drilling of holes some corrections where necessary.



This is an aluminium frame winch






And this is a bronze one.





Power winch





Without forgetting the proper orientation. Some will fit in different orientations.




And in the case of the mainsail winch we had wrong holes!



Final Check simulating the genoa sheets
