Reinke Super 10 again

[mireland]

Has anyone sailed a Reinke super 10 (37Ft) with steel hull? I am interested to know how they sail. Have looked at the Reinke site but gain very little from it. Seems to say that Reinkes are stopped by short coastal seas?

I have not sailed one but am butting in as I will be away for the rest of the week and I saw you did not get much reply last time you posted on this.

If the builder says it does not go well in short seas, as he says on his site, then one must assume that he is correct - designers/builders are not normally open with those things.

While it is hard to tell from a study drawing and photos it would appear to me that the comment is correct - the boat is relatively beamy (3.5 m on a 9 m waterline length) and that appears to be placed well forward and carried towards the bow. Coupled with a moderate canoe draft (draft without keel) and comparatively narrow stern section it may also be a pitcher (in my view a short waterline length boat needs broad sections at one end to dampen pitching in short seas - if that is so then obviously the stern is the best place for that).

I may be wrong but the builder seems to be saying the same. Looks a nice boat if that ability is not of concern.

No comment/knowledge on your post, but could you please post the URL for the designers site?

Thanks

Thanks for your replies. It all comes down to a sea trial then I guess - in a short steep sea! I am not experienced enough to be able to make many comparisons though so still crave info from someone who has sailed the blighters.

URL for Reinke is www.reinke-yacht.de

They have shortened a 12M hull to 9M waterline but retained the beam for accomodation so far as I can see. They say this might slow her down in a short steep sea. I am not racing and she seesm seaworthy but I do want a boat that will tack without exhausting everyone!

Thanks again,

Mike

The following comments may be of some help if not known already.

When sailing to windward one is usually at 40 something degrees to the waves and this makes a very big difference to the boat's motion (much less tendency to pitch as the effect is to lengthen the frequency of encounter with the waves) and its energy loss though pitching is much less than if the same waves are head on or very close to it.

In my opinion a useful test is to motor the boat directly into steep seas of wavelength much less than your waterline length and see how it behaves. If performance in steep short seas is important, and assuming moderate availability of power you should be able to drive the boat directly into close spaced seas as high as your forward freeboard (from trough to crest so they will not be on average be cresting quite as high as your freeboard) and into the wind driving them without coming to a stop through pitching action and should be able to maintain at very least 1/2 hull speed on average. A well found steel yacht should also easily be able to withstand the strains of this and not feel or sound as if it is struggling in any way. If the boat has low forward freeboard so that the seas are smaller when doing this trial than one would expect to be able to handle regularly then you either have to be prepared for having a very wet boat to sail or getting one with more freeboard forward.

Once the wavelength of the seas extends out beyond around the the same as the waterline length of the boat any boat will then proceed to go up and down over them and I am assuming that is not the case you are concerned about.

Contrary to ones natural inclination, carrying alot of weight in the bow (anchors, chain, warps, etc) will significantly reduce pitching due to the increase in longitudinal mass moment of inertia gained. There is a speed penalty in smooth water from carrying such weight in the ends of the boat but it is small and in my view of no consequence to a cruising boat.

Thanks so much for your detailed reply- very helpful indeed. I have now found a 2000 Reinke Super 10 for sale in the Netherlands. It has an Aluminium hull and is selling at £50000. The boat I am looking at is 1985 in steel and is offered at £27000. I like the boat but worry it may be too pricey. Now I know why people buy Nics or Contessa's or Sadler's etc!!!

Thanks again.
