For those following entire thread, I did contact NA mate in NZ and got this back:
""Good to hear from you,
I would say ‘cast a piece for either side and turn the current
keel into a bulb without increasing the draught’ (the word ‘draft’ refers to that which comes under the door!) is a good idea,
An additional retractable centreboard (see attached photo) might be worth considering.
The tenderness of the boat is a design issue and (you are right) the keel should be deeper and/or heavier.
If you like send the drawings as an email
attachment and I’ll give it some more thought.
(A side profile with the waterline, weights and centres of gravity of the boat and the keel and the sail plan with centres of effort of the sails
would be good).""
But I don't have the info he wants, but nonetheless now I know when I order a "draft" beer
it will be a cold one..
Correct on mast
height, 63'. Shortening it not really an option, would need new sails
, although did think if I did that would switch to a leisure boom and ditch the in mast
mast, like the idea of these although not sailed with one. Even in the marina the windage on the wider "in mast" mast does really roll her over and weight is lower too furled on in boom. However not going that far, already spent too much on mods.
I don't want to add more ballast and alter the waterline so putting lead in the bottom of the hull is a no no, the tankage is all wing tanks, deisel 1500L and water
1500L with crossflow pumps, I think the previous owner who spec'ed the design knew she would be tender with 1.8M, so sailed her half full, pumps are very slow though, wouldn't want to tack up wind using this technique although once i did a Uligamu, Maldives
to Oman in Jan a few years ago in previous boat,2 weeks on one tack enough upwind of a beam reach to really put me off long distance sailing, 4 knots ave, miserable single
handed voyage, got barnacles
upto the toe rail, water
ballasting would have been handy on that one.
Boat is a one off, a sort of copy of a Cheoy Lee
pilothouse. If I had a sister to learn from I would have. (The rudder
has the same draught as the keel BTW, presently.)
Every boat is my last boat!!! Who buys a boat thinking about the next one? (I suppose you are right, its true, its after you have bought it you think about the next one.)
I see there are a few responders who would have made good commercial
divers here, the ones who would just weld on some more keel and see what happens!
My last boat was very similar, very high inmast, steel pilot house. When I first sailed it it would broach at the slightest opportunity, I was sailing with too much up there but also I brought the mast top forward nearly a foot and this cured it, I did think that I could possibly overcome any balance issues after adding keel using similar tactics, just by adjusting the rigging.
I am into £.25M apprx so far on this boat so not really into too much risk going forward as now recently retired with limited top up facilities, so am going to take on board everything I have from this discussion, and procrastinate some more. And sail her a bit more upwind and see if I can get more from her as she is before doing what I already know needs doing, ie: get out the welder.
Meanwhile will also try harder to find original designer
, I need a dutch sailor to help me, who speaks good english
and is in holland
