Spectrum was an American name in welded aluminium boats, known for fishing boats and runabouts and, later on, small cabin models. Its roots are placed in Indiana in the 1970s; in the mid 1990s Brunswick folded it into its Fisher aluminium line, which is why some Fisher models appear here too. The three digit number in each name gives the length in centimetres, and the suffix tells you the layout: SL, SF, R, CLX and RLX, plus Open, Cabin and Timonier for open, cabin and wheelhouse versions.

Our model records list 31 Spectrum powerboats, four of them badged Fisher. Build years run from 1990 to 2000, so none is in current production. Lengths range from 3.35 to 6 metres, with half of the models between 4.1 and 5 metres. The CLX models run from the 411 CLX at 4.14 metres to the 485 CLX at 4.85 metres, and the R series from the 380 R to the 490 R. The cabin versions start with the 420 Cabin and end with the 600 Cabine at exactly 6 metres.

These are trailer boats for lakes, rivers and sheltered coastal water, used for fishing and day trips. Every one of them is now more than 25 years old, so value depends far more on condition than on the badge: a sound welded hull without corrosion at the transom and fittings, a straight bottom after years of beaching, and above all the outboard, which on a boat this size makes up a large share of the whole package.

Why do some Spectrum models also carry the Fisher name?

In the mid 1990s Brunswick took over Spectrum and merged it into its own Fisher aluminium line,

so boats such as the 410 SL and the 500 SF appear under both names.

What do the number and suffix in a Spectrum name mean?

For Spectrum: The three digit number is roughly the length in centimetres,

so a 465 CLX is 4.65 metres long.

Open marks the open boat, Cabin or Cabine the cabin version and Timonier the wheelhouse version.
