after 1d35 ran aground on beach, it's fin bulb only slipped off

Hi, there

Please understand my English..

I am a Korean sailor and new here hopping to get a solution for my 1D35.
Last week, I moored her on sandy beach but somehow it's been run on beach and lost it's fin bulb.
I checked the bottom of the keel and the bulb is just slipped off and others parts looks fine.

I've serched the bulb under water and sand for couple of days but not found.
so I am thinking to mold the bulb hear in Korea but I can't find the design on web
and the mamufacturer is carroll marine which is shut closed. 

3 questions

1. How can I get the design of fin bulb?
2. What is the best way to attach it to the lead at the bottom of the keel?
3. Any other recomendation for fixing or even sailing without it?

Have you tried to contact nelson/marek they are the designers and still in business they may be able to help or know who cast the keel bulb.

the bulb should have been through bolted to the keel foil. I would not try to sail without it. that boat has a lot of sail area and if it goes over it would be very likely to sink
I think the keel was made by Broomfield and son http://ibroomfieldandson.net
You should try posting on http://forums.sailinganarchy.com there are a lot of sailors that have owned and sailed a 1D35 on that forum

Thank you so much~
I will send a email to Nelson Mareck after this.

By the way there is no sign of bolt through to the keel foil.

I've tryed sailing at 15 knots of wind with 4 people but just little bit more of weather helm.
Anyhow I will not sail more than 20 knots though.

However isn't she head to the wind when it's over powered?

I hope to get it fix ASAP.

Thanks again.

No. With no bulb - the boat will tip over (heel) much more when over powered.

Thank you Mr. Zonker

 

However I tryed sailing her about 15 knots with 400 kgs crews for normal heeling with only main and travellar off little bit and was ok except worrying. Anyhow the ballast weight of 1145kg is whole keel weight, isn't it? so I calculated the only bulb of lead is about 345kgs (20*20*3.14*1/2*50*11). Thus the last of 800kgs of keel is still doing it's job. So I assumed it will be ok sailing under 15 knots of wind. What do you think of my thinking? Nevertheless I hope to get it fix as soon as I got the design of the bulb though.

You aren't factoring in the lever arm of the bulb being at the end of the keel.

Think in terms of foot pounds rather than just pounds.

It sounds like you only have about 1/2 the righting moment of the complete keel.
