Design and Construction
What defines the Raider 35 as a cruiser is not her numbers in isolation but how they cluster. The displacement-to-length ratio of 443 marks her as an ultra-heavy cruiser anchor, and combined with a length-to-beam ratio of 3.33 she is a beamy, voluminous hull rather than a lean racer. The motion comfort ratio of 34.9 and an immersion rate near 890 pounds per inch speak to a boat that carries load soberly and rides steady in a seaway. Her capsize screening value of 1.73 anchor is within the range where a boat could be considered for offshore passage work by that formula alone, and the theoretical hull speed of 6.6 knots sets the upper bound for her underbody. The wetted surface of the bottom runs about 26 square meters, a figure that matters more to the owner with a bottom job than to the sailor at the helm.
Rig and Handling
The Raider 35 is built with a masthead rig anchor, and the standing and running recommendations from the period record are precise enough to be useful decades later. Jib and genoa sheets are called out at 10.7 meters with a 14 mm diameter, the mainsheet at 26.6 meters, and the spinnaker sheet at 23.4 meters, all on 14 mm line. Those lengths tell you something about the cockpit geometry and the sweep of the sail plan: a mainsheet long enough to lead comfortably and a genoa sheet sized for a deep foretriangle. Under power the picture splits by engine choice. With a Yanmar 3GM30 driving through a shaft drive the calculated maximum speed is about five knots; with a Universal M35 on the same shaft-drive arrangement that figure rises to 5.7 knots. Either way the boat is happiest near her displacement hull speed rather than above it.
Accommodations
Below, the Raider 35 offers a toilet facility and a headroom described as above average for the type anchor, which on a 35-foot hull with that beam translates to a cabin that does not force the crew to stoop through the main saloon. The sources do not itemize berth counts or chart the galley, but the combination of above-average headroom and a beamy hull suggests a livable interior volume rather than a stripped weekend racer. For a cruising couple or small family, the space is part of what the ultra-heavy-cruiser classification promises.
Refits and Ownership
Ownership considerations are dominated by the boat's mass and wetted area. A 14,300-pound solid-fiberglass hull with a 26-square-meter bottom means antifouling and blister vigilance are recurring costs, and the shaft-drive Yanmar or Universal installations are straightforward mechanically but benefit from routine driveline inspection. The skeg-hung rudder is a robust arrangement for a cruiser of this weight, and the lead fin keel is a simple, repairable form.
The Verdict
The Raider 35 is a deliberately old-fashioned cruiser: heavy, beamy, and built to the standards of late-1960s Dutch production in solid glass. She will not win a buoy race, but her comfort ratios, capsize screening, and above-average headroom make her a sensible candidate for coastal and potentially offshore cruising on a budget of patience rather than speed.
Pros
- Ultra-heavy displacement and 1.73 capsize screening suit her to loaded cruising
- Above-average headroom and beamy hull give real interior volume
- Solid fiberglass hull and deck with skeg-hung rudder and lead fin keel
Cons
- Hull speed and engine calculations cap her near 5 to 5.7 knots
- Large wetted surface raises bottom maintenance effort
- Masthead rig and heavy displacement limit light-air performance
