113 Yvette

I have taken the following information from research I have undertaken and in particular extracts from letters sent to me by:                               Lars-Olof Norlin                                      Marine Engineer                                         Naval Architect/R.I.T. (1956)

Mr Norlin was a friend of Olle Enderlein and also competed against him while racing in the 1960’s. Mr Norlin surveyed Yvette for me in 2007 before I bought her and also sent some general information about the type of yacht and the development leading to her design. I also spoke to him several times on the phone especially about the rig.          

Yvette designed by Olle Enderlein.


“She is developed from the American yachts of ‘Shoretender’ type, which Olle Enderlein became familiar with when he was employed by the Sparkman and Stephens office in the USA.”

“In Sweden the development of the type is named as a ‘Coast Cruiser’ (sail mark KR) running parallel to the international denomination of ‘Skerry Cruiser’ (sail mark SK), originally designed for sailing in the semi-protected waters in the Swedish archipelagos. However in 1925 new building rules were introduced for the SK’s in order to make them more seaworthy through strongly built hulls, strong keel bolts, properly dimensioned chain plates and rigging etc. These new 1925 rules for building have since been applied for most of the yachts built with the intention of cruising.”

“The KR’s are also intended and used for ocean racing in the Baltic as well as in the North Sea. Olle Enderlein’s designs have proven to be well dimensioned, easy to sail and successful when racing. S/Y Yvette built in 1964 is a typical yacht of that period. manufactured by quality craftsmen in a well know Swedish yard.”

Sail number H7

“(H=Hav (Open Sea) 7=7 metres (Measured by SHR/Swedish Ocean Racing Rule. Compatible with the rule of RORC)”

Note: When viewing Yvette she is obviously no more than a sweet looking fast cruiser. I do not think that Yvette is an actual 7 metre racing machine, (If that’s what they were.) she may have a really nice hull but she has a deck stepped mast and coach roof etc. she is definitely fitted out for cruising. I am not familiar with the 7 metre class and can’t find much when searching the internet. I don’t know the dimensions that make up to a 7 metre to the rule of RORC, so can’t check with the physical measurements of Yvette, but figure that Yvette is a cruiser, although I hope she will prove to be fast.

Until I bought her Yvette had spent 8 months of the year every year out of the water. This is what they do in Sweden because everything freezes over. She therefore spent two thirds of her life out of the water and under cover. The hull has not needed any attention other than painting.

I purchased Yvette from the 3rd owner. He had sailed Yvette with friends since her launch in 1964 he was a friend of the original owner they sailed with another friend. The original owner died and the 2nd friend bought the boat, he died and the 3rd friend bought the boat. All 3 friends apparently knew Olle Enderlein the designer of Yvette.

Since purchasing Yvette in May 2007 and sailing her back to Cardiff from Stockholm I have worked away steadily under taking a refit while having short cruises in the summers. I have completed every facet of the work myself from installing the engine to sewing the covers and curtains it has been incredibly enjoyable.

The major change is to the rig. Yvette started out life as a sloop. Sometime during the 2nd or 3rd ownership of Yvette the owners discussed tuning her into a ketch with Olle Enderlein. They got his blessing, he said that a small bowsprit would also be required to enable the correct balance etc. When I picked up Yvette she had a bow platform affair with huge amounts of stainless steel that you could walk out onto. It was well manufactured and fitted but obviously sent a lot of weight where you don’t need it.

The mizzen mast was stepped in the cockpit sole. The arrangement wasn’t good and the compression had distorted the cockpit sole to such an extent that it let water in and was rotten. There were no chain plates for the mizzen they used the main backstays for the mizzen backstays and installed a couple of little eye bolts for the main mast back stays. The mizzen shrouds were put to the stanchion bases. The mizzen mast was aluminium painted white and they painted the wooden main mast to match. She also had 2 roller furlers which were poorly conceived. It was all pretty shoddy and I spent several days making everything safe before the trip back to the UK..

I spoke to Olaf Norlin about the rig and he agreed with me that Yvette would sail well and efficiently with a main, mizzen and bowsprit, he seemed to know of this type designed by Olle Enderlein and having this rig. Mr Norlin said as long as the bowsprit didn’t have all the cumbersome weighty bits and the mizzen was properly stepped and rigged, the mizzen is so small and light that trim would not be effected.

Anyway I have configured a mizzen and mizzen staysail etc. I can then tweek the helm balance easier. I have moved from a ketch with the mizzen stepped on the cockpit sole to a yawl with the mizzen properly deck stepped with appropriate under-deck support. The main mast has been completely renovated and has gone back to being varnished. I made the bowsprit, mizzen mast and mizzen boom from Douglas Fir. She looks splendid.

To summarise the other work I have completely renovated the cockpit area, installed a new engine, new electrics all new batteries and charging system etc, new navigation gear and electronics, updated all the safety gear. Made a new cockpit table and a new saloon table, moved the fridge from the inside to a cockpit locker thus creating a small navigation station. Taken off the old gas cooker system and installed a pair of non pressurised spirit burners. Made new seating, curtains and other furnishings. Installed a new full size toilet, new freshwater system, new bilge pump systems etc.
