drupal db schema error - php

Question

In a module I'm building for Drupal 7 I'm trying to create a DB schema for the installing and uninstalling process. When enabling the module (and thus installing it) I get an error and my table is not created.
Can anybody see where it's going wrong?
<?php
/**
* Implementation of hook_schema().
*/
function wind_and_waves_schema() {
$schema['wind_and_waves'] = array(
'description' => 'Caches wind and waves data',
'fields' => array(
'id' => array(
'description' => 'The unique identifier for this item.',
'type' => 'serial',
'disp-width' => '11',
'unsigned' => TRUE,
),
'creation' => array(
'description' => 'Moment the data has been loaded',
'mysql_type' => 'datetime',
'disp-width' => '11',
),
'load_time' => array(
'description' => 'Moment the wind data has been loaded by rijkswaterstaat',
'mysql_type' => 'datetime',
'disp-width' => '11',
),
'hoek_wind_snelheid' => array(
'description' => 'Windsnelheid op hoek',
'type' => 'varchar',
'disp-width' => '11',
),
'hoek_wind_stoot' => array(
'description' => 'Windstoot op hoek',
'type' => 'varchar',
'disp-width' => '11',
),
'hoek_wind_richting' => array(
'description' => 'Windrichting op hoek',
'type' => 'varchar',
'disp-width' => '11',
),
'hoek_golf_hoogte' => array(
'description' => 'golfhoogte op hoek',
'type' => 'varchar',
'disp-width' => '11',
),
'ijmuiden_wind_snelheid' => array(
'description' => 'Windsnelheid op ijmuiden',
'type' => 'varchar',
'disp-width' => '11',
),
'ijmuiden_wind_stoot' => array(
'description' => 'Windstoot op ijmuiden',
'type' => 'varchar',
'disp-width' => '11',
),
'ijmuiden_wind_richting' => array(
'description' => 'Windrichting op ijmuiden',
'type' => 'varchar',
'disp-width' => '11',
),
'ijmuiden_golf_hoogte' => array(
'description' => 'golfhoogte op ijmuiden',
'type' => 'varchar',
'disp-width' => '11',
),
'golf_periode' => array(
'description' => 'golfperiode',
'type' => 'varchar',
'disp-width' => '11',
),
'watertemp' => array(
'description' => 'watertemperatuur',
'type' => 'varchar',
'disp-width' => '11',
),
'luchttemp' => array(
'description' => 'luchttemperatuur',
'type' => 'varchar',
'disp-width' => '11',
),
),
'primary key' => array('id'),
);
return $schema;
}
?>
The error I get:

All columns of type varchar need a length property, e.g.:
'luchttemp' => array(
'description' => 'luchttemperatuur',
'type' => 'varchar',
'length' => 11
)
disp-width is only valid for non-varchar type columns
