Stuart,
Welcome to the forum my good friend. You will find a wealth of information here as well as some incredibly nice, knowledgeable, and helpful people.
Just an FYI. It is best if you include your boat name, model, hull number and location below your signature line. This information will assist those who respond as there are variations among models and hull numbers. Additionally, knowing your location someone can often suggest services of suppliers or contractors in your area.
All the Best,
Paul Stascavage
