Review of Dehler 35 Cruising

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The interior is like nearly all boats made of wood.
The boat is equipped with 3 cabins, 6 berths, a galley, 150.0 liter fresh water capacity, toilet facility and 60.0 liter waste water capacity.

The Dehler 35 Cruising 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.

Full keel

The Dehler 35 Cruising is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat 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.

Dehler 35 Cruising may be equipped with an inboard Yanmar 3 diesel engine at 27 hp (20 kW). The speed is 8.0 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.

The fuel tank has a capacity of 70.0 liters (18 US gallons, 15 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Dehler 35 Cruising is 1.93, 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 Cruising is about 203 kg/cm, alternatively 1139 lbs/inch.
Meaning: if you load 203 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1139 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Dehler 35 Cruising is 23.0.

What is L/B (Length Beam Ratio)?

The l/b ratio for Dehler 35 Cruising is 3.18.

What is a Ballast Ratio?

The ballast ratio for Dehler 35 Cruising is 43%.

What is Displacement Length Ratio?

The DL-ratio for Dehler 35 Cruising is 182 which categorizes this boat among 'light racers'.

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.
