The Grinde is a seaworthy sailing boat with a keel shape reminiscent of the back and fin of a whale.
history
The origin of the Grinde can be seen in the small sister boat , the Spaekhugger , constructed in 1969 by the Dane Peter Bruun . This extremely successful boat was followed in 1972 by the rare large Kaskelot. In 1974, the then 24-year-old designer Peter Bruun brought the prototype of the Grinde into the water.
In 1975 the series production of the Grinde began at the Flipper Scow shipyard, where the majority of the boats were also built. Most of the boats are from the years 1976–78 (approx. Up to serial number 380). In 1979 Peter Bruun took over production and the shipyard was henceforth called Peter Bruun Baadebyggeri. Fewer and fewer boats were built over the years: in 1982 the serial number was 444, the year 1984 the 465. The last shipyard-built grinde was built in 1989 and has the serial number 481. The highest and very last hull number 482 has a self-made grinde from 1989 .
85% of the boats are shipyard buildings, the remaining 15% are self-built boats.
There were not many modifications in the series: The water drainage of the front hatch was changed from the hose to the gutter (from 1978), a few boats were built with dinette facilities (U-shaped sofa).
Construction
The Grinde, drawn by Peter Bruun, is a pointed gate with a spoon bow in GRP construction. The fuselage is solidly laminated with isophthalic resin using the hand lay-up process and has a laminate thickness of 16 layers under water and a laminate thickness of ten layers above water. The deck laminate has a sandwich construction with a balsa wood core. She has a solid plug mast with just one Saling . Originally a boat diesel of the type Bukh DV10 with 10 HP was used as auxiliary drive , later a Yanmar 2GM20 with 18 HP. The hull speed of 6.7 knots reaches the Grinde with 14.5 HP.
The salon
The Grinde has an enormous space below deck. The large width of 3.12 m in the saloon area enabled the installation of seven berths and a pantry area, which was spacious for the time, with a cool box, two-burner stove and large kitchen cupboard as well as a very comfortable navigation area. Very small overhangs made it possible to use almost the entire length of the hull.
The Grinde therefore looks like a 10 m boat below deck. The standing height of 1.80 m in the forecastle and 1.85 m in the saloon underlines this impression. The saloon berths are 1.90 m long and have been installed as a lengthways or U-shaped sofa. The extra-large dog bunk has a length of 2.20 m with a shoulder width of about 1 m. Two pilot berths in the original version enable a safe sleep for night trips.
The forecastle
Contrary to today's standard, the Grinde does not have a closed toilet room. It is only possible to separate from the salon. This is certainly to be regarded as a disadvantage in some situations, but enabled the installation of a very large forecastle triangle of 2 m × 1.80 m. There is a stainless steel washbasin with a foot pump, spacious shelves under the washstand, a large closet, a high wardrobe behind the toilet, two large sailing boxes under the forward berths and an anchor locker in the bow. The large forward hatch, which enables the sails to be changed safely even in a storm, has proven to be particularly practical and seaworthy.
Sailing characteristics
It is its sailing properties in particular that have made the Grinde such a popular and well-known boat. Thanks to the relatively modern underwater hull, the sailing characteristics are very good compared to other family boats of this year or size. The Grinde reaches above-average speeds on all courses and runs a very good height on the wind. She is fast, stiff, can take a lot of wind and is always safe to sail. With its sails load rating of 4.72, it is clearly in the performance range.
