Grinde Sailboat

[Imke]

Boththe hull and the deck is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The deck is a double deck which improves the indoor climate.

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.

The boat is equipped with one cabin, 7 berths, a galley, 90.0 liter fresh water capacity and toilet facility.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

The keel is made of iron.Many people prefer lead keel in favour of iron.The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag.In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.As the surface of a fin type keel is just a fraction of the total wet surface,the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

The theoretical maximal speed of a displacement boat of this length is 6.7 knots.The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster.The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level.The immersion rate for Grinde is about 158 kg/cm, alternatively 889 lbs/inch.

Meaning: if you load 158 kg cargo on the boat then it will sink 1 cm.Alternatively, if you load 889 lbs cargo on the boat it will sink 1 inch.

This section is statistical comparison with similar boats of the same category.The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

The Motion Comfort Ratio for Grinde is 20.9.

Low High 54% 0 50 100Comparing this ratio with similar sailboats show that it is more comfortable than 54% of all similar sailboat designs.This comfort value is just above average.

The l/b ratio for Grinde is 2.63.

Slim Wide 92% 0 50 100Compared with other similar sailboats it is more spacy than 92% of all other designs.It seems that the designer has chosen a significantly more spacy hull design.

The ballast ratio for Grinde is 40%.

Low High 50% 0 50 100This ballast ratio shows a righting moment that is higher than 50% of all similar sailboat designs.This righting moment (ability to resist heeling) is spot on average!

The DL-ratio for Grinde is 222 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 58% 0 50 10058% of all similar sailboat designs are categorized as heavier.A light displacement requires less sailarea and has higher accellerations.

When buying anti-fouling bottom paint, it's nice to know how much to buy.The surface of the wet bottom is about 27m2 (290 ft2).

Based on this, your favourite maritime shop can tell you the quantity you need.

The Grinde is a moderate weight sailboat which is slightly under powered. It is very stable / stiff and has a low righting capability if capsized. It is best suited as a coastal cruiser. The fuel capacity is originally very small. There is a very short water supply range.

I bought my first sailboat, a pram called A-jolle, the poor cousin of the Optimist, at the tender age of 5 1/2. The following 45 years I have sailed any boat I could afford or yachts willing to let me come along. While the kids was small and income scarce I sailed sailboard and spent hours waiting for wind at the beaches surrounding Stavanger.

go dag! dette er din yngste datter som gjerne vil ha sin kropp tilbake p sidens bilde fra kockpiten i SALT. vil du venligst sette den p igjen? s skal jeg nk beske siden igjen. den var veldig fin!! seilerhilsen fra danmark

Hi Douglas Jones,

I am sorry, but I have never heard of any Kaskelots outside of Scandinavia and Germany. I had a Grinde before I bought Salt and the difference is not as much in size and room, as it is in sailpower or more correct in power to pound through the waves. So you might think twice about the huge amount of dollars you have to pay for the extra feet.

If not entirely wrong Peter Bruun only made 49 Kaskelots, while there are more than 750 Grindes. At the time beeing I only know about one German Kaskelot for sale. The following is a copy of and e-mail from the German Grindeclub:

Hallo Grinde freunden,

Mein Freund hat seine Kaskelot bau nr. 49 mit Grinde aufbau zu verkaufen.

Dieses Schif ist absolut die schnste den es berhaupt gibt. Bauwjahr 1990.

Espen, Thank you so much for your response and good information. Perhaps a trip to Germany is in the future! I read your story about your diesel heater with interest. I installed a kerosene heater on Avalon ( my Grinde ) and have been very happy with it. It certainly makes cold weather sailing comfortable to go below and have a warm and dry cabin. Here in Maine it is used quite a bit. Thanks again- Douglas

Thank you for your honest comment !

At this moment I am still in New Zealand and will be flying back to Holland this week.

I have allways loved the Grinde and Kaskelot designs.

In the past I have sailed the Spaekhuger a few times on AEro in Denmark.

Are there any Kaskelots for sale in Scandinavia ?

Hi Guys

New Zealand calling

Just searching for some information. Own a Kaskelot for 5 years now. I am interested in finding out some technical information. More then likely none around but somebody may have done the calculations.

STIX value

GZ curve

IMS Stability Index.

My Kaskelot previously called SV Njord now renamed SV Wiropet based in Wellington NZ.

Dear Tom.

We have tried to answer your question, but we must admit, that we do not know anything about this subject. In denmark we have a similar handicap system, like IMS. We can supply information about this system.

In Europe the danish grindeclub i forum for marsvin, grinde and kaskelot owners. We would like to invite you into our club, where you can share information about your boat with other kaskelot owners.

All I need is your postal adress. If I receive this information, I will send you the latest edition of our newsletter and an invitation to be a member of the club. The anual fee is app. 40 US dollar

Se

Sincerely yours

Joergen Binzer

Chairman of the grindeclub

My husband Bill and I went through a similar journey in 2009 when we finally bought our Crealock 37, Terrwyn. We absolutely love her and she has proven to be both sea worthy and sea kindly having taken us 2/3 around the world (she is now waiting for us in Simonstown, South Africa). We plan to sail her to Trinidad starting this November and leave her there for a season (good excuse to do some exploring of the Caribbean!). After that we plan to sail back to New Zealand and keep Terrwyn there at our New Zealand residence (yet to be purchased!).

Really good article you guys! You really take the reader through the whole process. We have shared it through the Distant Shores TV Facebook Page since we know it will be of great interest to anyone going through the boat-buying process themselves.

3) Based on your experience as an Outward Bound captain, do you have any other information/views on their pros and cons? My understanding is that Outward Bound is going to a somewhat different design in fiberglass. Also, could they reach hull speed in 15 knot winds and would you think they could handle 6 foot waves offshore if weighed with rock ballast or stores?

2) I also looked at the Outward Bound sailing course years ago but decided to take some ASA courses instead because they taught how to handle the more commonplace sloops. However, I am reconsidering that.

3) I tend to look at the original intent of tools. The sailboat is the only tool that originally let one haul heavy loads of provisions for long distances with low technology (iron chisels,etc.) Yet today the Coast Guard has to constantly haul people out of trouble even with accurate weather forecasts and diesel engines. What would people do without NOAA forecasts, radios, and mechanical engines?

4) The East Coast has hundreds of miles of sandy coastline (Assateague island in Maryland, Hatteras in North Carolina, etc.) that could be a refuge in a storm and yet almost none of our sailboats can land on a beach through heavy surf.
