thwart and rowlocks for use when under power and rowing. Several versions of the Otter were manufactured. The original design consisted of a single skin glass fibre hull and a Gunter rig (without spinnaker). Later models used the more successful Bermudan rig (with optional spinnaker), and a double skinned 'unsinkable' hull with integrated buoyancy tanks. The hull weight and sail area depend on the version. The adjacent picture shows the original wooden masted Gunter sailplan. The otter dinghy no longer appears in the official Portsmouth Yardstick List., however, during production it had a PY of 134, placing it similar to but slightly fast than the Topper with a PY of 136. According to Noblemarine, the Otter has a PN of 1275, but this source of this information is unknown and may be unreliable since the other dimensions quoted are contradictory to the manufacturer's description. In 2007 the RYA also quoted the Otters PN as 1275 but have since removed the boat from the list.
