It may be down to actual operating conditions - boat stove flues are generally too short - if the bridges had
more headroom then we could have taller flues & stoves would work better. Whilst a throat plate is intended
to stop excess heat escaping, it also reduces airflow and sometimes has to be placed "out of position" or even
removed to get a stove to draw properly - some days it will work fine, others particularly like todays foggy start,
it will be difficult to get going with a throat plate fitted as intended.
