Not really.  I am not sure there are any in Germany. Not sure if any of the dutch are left after they tried to add twin wires, racks and asymmetric kites in the early 2000s...

I am also not sure they would have met our "requirements" regarding crew weight and self draining cockpit.

Last week we sailed with > 190 kgs  crew weight and the int14 hull was still doing fine :-)

Hi
have you considered a Hornet?
Meets most of your requirements, it is actually in the class rules that you can sail 3 up without the trapeze.
With the right deck layout you could have a competitive 3 person race boat in certain conditions

Great for the kids and your wallet

Our "detuning-projekt" is still alive:

Over the winter my wife made an upper cover, we replaced some cleats and the standing rigging.
At the same time a mouse built a nest in the cockpit structure holding the pole in the bow even though the hull was upside down...

This week-end I sailed it with my 30 kgs daughter so about 120 kgs between the two of us in very shifty and gusty winds (at least force 6 gusts in "forum wind" Big smile), so I opted for the cut-down main (about 8 sqm) and a borrowed jib of a 420 (2,8 sqm). That changed the nature of the boat dramatically compared to the standard int14 sail area and worked very well.

Maybe the hull shape of a 1990s int14 was still better suited to such a small sail area anyway?

Yesterday we tested the „entertaining the kids” aspect:

•     Towing an inflatable “unicorn” worked surprisingly well
•     Using the newly installed “free to us” second hand hiking straps to bend over backwards until the head touches the water surfaces worked
•     Trapezing worked
•     Changing to off-boom sheeting and removing the helm’s trapeze wires in combination with the mast mounted far forward and absence of side decks creates sufficient room for 2 adults and a kid even on only 14 foot hull length.
•     Furling the jib adds the area in front of the mast, e.g. when the kite is up

(bullet points sorted according to decreasing importance from my daughter’s point of view )

So overall I think the “detuning” worked 

The name on the kite is most likely a measurer rather than the owner.

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...

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.

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.

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.

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.

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!
