Don’t think that the stump was original, the Ovy Howlett that we had 1301 still had a hog stepped mast

Hmm, yes, I very much doubt that setup is original, but I would definitely want lowers with any distance of gooseneck above mast. The kicker load is going in the mast whatever.
The big question is what are you planning to do with mast and sails. And a second question, which you probably can't answer, is how well does the rig you've got actually work. A mainsail for a properly designed twin spreader rig will have entirely the wrong luff round to be used without caps, but there was a tendency in some classes and some places to just bung caps on a single spreader rig to hold up a kite downwind without much thought about upwind. In my opinion that was not a good rig, but if you have one taking caps off isn't an issue. |

This
week-end we weighed the hull: About 89
kgs is pretty goodto me, considering some blocks and the mainsheet base are missing
it should be more or less the minimum weight of 30 years ago. |

It took some time to realise there were better ways of doing things. Its not so much that space frames are bad per se but that those big fabricated aluminium constructions were expensive and heavy, especially compared to having the same strength built into internal framing with carbon. And also the 14 rule set of the time tended to push people down odd paths. Neither expensive nor heavy were significant issues for the 14s of that period!

Until the 1996 unification foredecks weren't allowed, so spaceframes were very much the thing.

That space frame looks identical to the one we had in 1188, I think that boat went to Belgium?????
I'm sure the number will be in the hull somewhere. 1188 was a single trapeze rules converted to twin trapeze rules, great boat but the mast was long, heavy & didn't bend at all! |

We do not really know the sail number of our current i14 as the paperwork is lost and we did not find any number on the hull yet. But it looks like it was built for asymmetric kites right away, so it should be after the rule change in 1989.
The aluminum
mast would still qualify as heavy (though shorter as it is stepped on top of
the space frame) but I hope it will bend somewhat at the top due to being
tapered.
There are
probably only 2 or 3 RS400 in Germany so spare riggs will be hard to find. Sail
area would be on the high side of what we are targeting and I am not sure how
well they would take a single trapeze.
However we
looked at the suggestion to use a 29er rig again: Actually there are quite a
few 29er for sale to due to “serious” youth teams moving on. Maybe we should
talk some of the teams into selling their spare parts/sails separately and
build a rigg from that??? I guess that would break our “low budget approach” and we would end up paying ten times the money for rigg & sails
compared to what we initially paid for the boat J
Today will
be another day putting glass&epoxy on rudderblade and daggerboard, at the same time the parcels
with parts for the “bespoke” rudder stock we are intending to build are arriving…. Good news
is that pressure testing the hull went kind of o.k., even though the hull does
not meet the class rules from back then anymore. |

We had the first customer Ovy Howlett 1B, 1302, and that was stumped from new. At my request the spaceframe included an aluminium plate underneath the rectangular section, on top of which I put the mast step and underneath a section of old mast as the stump. I don't believe it's the one in the pics as the plate on which the step sits is somewhat smaller.
If it is a Howlett 1B then it will be 1990 or later. The first one was built & demoed in 1990 and production started that winter. |

Another
update: Kite We
hoisted the one that came with the boat. The front leach is way too long. It
also says “2003” and a name of a guy that also took part in the 2003 POW/Euros
at Hayling Island that we watched from our first Penultimate (I cannot really
claim we “competed” in any way, we just have been there out on the water…). The
guy had a current boat back then so the kite most likely is intended for
post-95 rules rigg. But
a RS800 kite fits quite well. We
figured out a single line system for the kite pole. These boats still had an
extra line to extend the pole when they were built, but all the blocks and
cleats had disappeared anyway. Our new halyard/retrieval line is a little thin
but ok when wearing gloves… Rudder We
(kind of) finished our DIY lifting rudder based on the partially rotten
original fixed rudder. It looks pretty agricultural (everything mounted to two
rectangular 3 mm aluminum sheets), but it works… Mainsail One
was very tired below the sail numbers, so my wife simply cut it horizontally
and is now putting the reinforcements for clew and tack on the lower corners of
the upper part. The upper part should be about 8 sqm so together with the 5.5
sqm jib it will be a decent sail area for a single trapeze boat. First sail We
used the other main sail that came with the boat. It is in far better condition
so we will leave it like it is for now. In the light winds it yielded some
welcome extra push... To me it looks like some mast pre-bend
induced with the uppers is necessary to avoid an excessively “deep” sail shape. The
smaller kite together with the big kite sock and the thin halyard worked really
well. Unfortunately
the daggerboard did not fit the case properly anymore, so the vang just cleared
its upper front edge when fully releasedL.
After many hours of sanding down both daggerboard and case it is still an
issue… The case ( or actually the
insert) looks like they used some kind of paper based material back in 1990... Edited by skslr - 01 Jun 21 at 6:59am |
