Review of Diva 355

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 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 3 cabins, 4-7 berths, a galley, 100.0 liter fresh water capacity and toilet facility.

The Diva 355 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.

Fin keel

The Diva 355 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

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 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.

The Diva 355 has been equipped with different engine alternatives.

Alternative 1:

Diva 355 may be equipped with an inboard Yanmar diesel engine at 18 hp (13 kW). Calculated max speed is about 5.5 knots

Alternative 2:

The boat may be equipped with an inboard Volvo Penta engine

The fuel tank has a capacity of 60.0 liters (15 US gallons, 13 imperial gallons).

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 34m² (365 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.
