Oostende Vor Anker

[Javelin]

Hmm, need to get Sprit finished then for HISW.
She currently looks like this....

No pressure...........

Henry mentioned the scallops for the bowthruster. I see what he means now!

Quite a complex solution.

Be interested to see if it produces less drag than the traditional 'eyebrow'.

Not convinced you'll notice any difference on a boat like a Nic39.

 

[Javelin]

I don't want it to make a difference, I guess that's the point.
We usually expect to see a drop of between 1/2 to 1 1/4 knts with a conventional bow thruster tube.
The addition of eyebrows in my experience makes little if any difference.
When I did the first one of these on a Southerly 38 we saw no noticeable speed loss.
We had the same result on one I did on an Ovni 38

 

[Tradewinds]

I bow to your greater knowledge.

I also didn't appreciate that a tunnel made that much difference to boat speed.

Will follow with interest.

PS. Is that Mac's Ovni?

 

[Javelin]

yes

Thanks for that, Javelin, it's fascinating. Makes sense that it's the aft edge of the tunnel that causes the drag.

I didn't see any speed loss with our bow thruster fitted but then we're built for comfort not speed

More like Rock n Roll than speed.
Are you going into the Montgomery dock again this year

 

[Otter]

Are you going into the Montgomery dock again this year?

Nope, Dorset the CI's again this year. Dogs make foreign destinations complicated.

I have a nephew getting married on the Saturday.
I am ushering, and witnessing signatures so it's a three line whip...

As Black Adder would say... bugger

Shame, in your boat you could have got there, come back & done the wedding and returned to Ostend before anyone noticed you were missing from either event!

Very much hope to go but depends on the weather forecast, got a cardiology appointment on the 30th
