Re: fairing block

Minaret;
Yes the ready made may last forever but I believe this isn't really complicated.
I'm a better than fair woodworker.

Iooking at buying some teak for other projects and I'm sure their will be enough cutoffs to make a 6" diameter clyinder.

Under water glue anyone?
Resorcinol?
And coated w/ epoxy.?

Re: fairing block

LoL So we've come full circle.
A Polyurethane glue.
Wood core.
An epoxy protective coating.
Adhered to hull with 5200.
Sounds right.

Amazing site with a lot of knowledge.
Thanks all

Have to measure it but for this conversation i imagine a 6" diameter cylinder 3" or so high. a 2" hole for the transducer and after cure shaped for the deadrise of the hull.
Thanks again


Remember you will need a block on the inside as well, make your cylinder twice as tall and cut it in half at the right angle (after boring the hole!), then you will have both pieces. 3" would barely be enough on a boat with an almost flat bottom. The more deadrise, the bigger the block must be.


Why a cylinder though? Make that sucker fairing block shaped instead. Like a torpedo level. A 6" cylinder will create a ridiculous amount of resistance and turbulence. More likely to hit something and break too.

Re: fairing block

Thanks: Yes completely understood.
I'll even coat this bugger in epoxy.

At the beginning of this journey (18 years ago) my biggest fear had to do with sinking.

Oddly....
that's still my focus.
Lol.

With this post this question has been eclipsed.
Now it has to do with my repairs outliving me...and there will be but one more. clorox bottle sailboat still floating...

When my boat comes up for sail....one day,.... and someone asks about a bluewater round the world cruiser....don't send them to my boat.....LoL.
Capable Coastal.....you bet.
Cheers
