Lead ballast in bow - why?
 

I am going to assume that you are talking about a 120hp Ford Lehman diesel,
and that the vessel is a powerboat, not a sailboat? If that's the case,
there just doesn't seem to me to be any rational argument for the lead
ingots . I would pull them. They can only add to the pitching moment.

hi all

I have a Halvorsen Island Gypsy 30 displacement cruiser built in 1978. The
boat has the original Ford 120hp engine. I have owned the boat for a
couple
of months. Someone has placed about 10 ingots of lead in the bow "v" which
sit unsecured but somewhat wedged and immobile.

The boat sits quite level (if anything with a slight bias toward being low
in the bows - not surprising) and floats within its marked waterline
(apparently fine).

Does anyone know if this is a standard fitting or has someone just had a
bright idea at sometime and should I take it all out? I would have thought
this would have been glassed in if it were deemed necessary by the
manufacturer . . . Kong and Halvorsen.

thanks all

The Ford is similar to a Lehman but it is a 120 hp 6cyl "Tempest" - There
were a few different types of Ford conversion engines as I understand it:
Lehman, Lees, Tempest and Bowman. Yes it is a displacement cruiser, a power
boat. A trawler style/passagemaker as folk seem to be calling them these
days.

I have had a reply from the manufacturer Mr Halvorsen himself and I will
include it below as this thread has attracted some interest.

Many thanks to all for your considered responses.

Dear Shawn,
I'd take the lead out. Someone may have put them there to trim out for the
dinghy and davits, but if she trims OK now then get rid of it. These boats
are better if kept lighter in the bow, i.e. better to be down by the stern,
rather than by the bow. Happy boating.
Regards Harvey Halvorsen.

Placing lead in the bow of a boat is a relatively common practice.
Especially with large boats. The lead helps keep the boat sitting level and
helps it plane easier with smaller engines. I had a 68' Luhrs Sport
fisherman with a 318 Chrysler crown and it had a little over 500lbs of lead
in the bow. You can remove it but will find the boat will not be as stable
in rough water and will not plane as easily. I would leave it and if you
are concerned with it moving around then pour some A/B foam around it. That
stuff is so "sticky" it now use as an adhesive in some applications...

Hey Mark,
The guy said "Displacement Cruiser"! That means it DOESN'T plane.


me who actually reads the posts first......

Who snips the Q so nobody can use the thread, except avec toi, eh?

And complains, instead of contributing. Talk about me, me, me.

Lowering the bow may raise the transom reducing suction behind it,
feeding a prop a little better and lengthening the waterline a
little, especially with a swept stem.

My row boat, a 14' cartop Alumi, goes easier with the mate in the
bow than in the stern thwarts.

all fixed folks and thanks. I have removed the lead which was completely
unnecessary in a displacement cruiser and it is sitting more level and I
think steers a little sweeter in a following sea. Thanks all.
