The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 3 cabins, 6 berths, a galley, 130.0 liter fresh water capacity and toilet facility.
The Dehler 35 cws is equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a gennaker or a spinnaker for optimal speed.
The Dehler 35 cws has been built with different keel alternatives.
Wing keel
But be aware that even though a Wing Keel keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.
The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.
Deep keel
One option is a deep keel. A deep keel provide a better healing moment than a shallow keel.
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.
Dehler 35 cws can only enter major marinas as the draft is about 1.88 - 1.98 meter (6.17 - 6.47 ft) dependent on the load. See immersion rate below.
Shallow keel
Another option is a shallow keel. A shallow keel allow to sail both coastal and inland waters.
This keel is also made of iron.
The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.
Fin keel
Another option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
The boat can only enter major marinas as the draft is about 1.90 - 2.00 meter (6.23 - 6.53 ft) dependent on the load. See immersion rate below.
Sailing characteristics
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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Dehler 35 cws is 1.95, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.4 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 Dehler 35 cws is about 205 kg/cm, alternatively 1149 lbs/inch.
Meaning: if you load 205 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1149 lbs cargo on the boat it will sink 1 inch.

The ballast ratio for Dehler 35 cws is 43%.
What is Displacement Length Ratio?
The DL-ratio for Dehler 35 cws is 182 which categorizes this boat among 'light racers'.
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 36m2 (387 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.
Note: If you use a paint roller you will need more paint than if you use a paintbrush.
If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
