Read the boat-cover price guideChoosing a cover for the Seamaster 813
Request replacement Seamaster 813 canopy canvas or a fitted cockpit cover using the enclosure on your own boat as the starting point. A canopy protects seating and controls while preserving access; a separate tonneau closes the cockpit when it is not occupied.
Give the full 813 designation rather than only Seamaster. The catalogue also lists Seamaster 8, 820 and 840, but those names do not establish equivalent supports or canvas. Show your cabin edge, canopy roof line and rear closure before choosing which sections to replace.
Cover options for the boat as fitted
Whether a cover follows an existing frame, secures to existing fasteners, or fits another existing arrangement depends on what is actually on this boat. Confirm its fittings before choosing; UK Boat Covers supplies the cover, not framework.
What to include with a quote request
Take clear photos of the individual boat and its present fittings. The model name alone cannot confirm the pattern or fit.
- Confirm the complete Seamaster 813 designation.
- Show the fitted roof profile from both sides.
- Photograph cabin attachments and rear-panel corners.
- Identify sections to retain and any moved supports or fasteners.
Can a cover be copied by post?
For Seamaster 813 postal copying, photograph the canopy fitted and label the connecting panels before removal. Describe any sagging or tight edges and explain changes made to the boat since the cover was produced. An incomplete sample needs an agreed assessment; do not substitute an 820 or 840 cover based on its name.
Postal copying uses your existing cover as a pattern; it does not include supplying or installing support framework.
Fitting and measurements for the Seamaster 813
Check the Seamaster 813 enclosure with roof, sides and rear secured together. Show the corners where panel tension changes and mark any zip that no longer closes easily. Existing support positions and the cabin attachment are the useful references, not a length estimate inferred from the number 813.
Contact us before measuring: agree the attachment points, panel joins and photos needed for this cover. Do not send unsupported dimensions or remove fittings to match a different boat's pattern.
Read the measurement guideMarine canvas, windows and fastening details
Marine acrylic is an option for a breathable canopy with clear windows where needed; marine PVC can be discussed for a separate cockpit closure. Compare the fabric's handling with how often your panels are removed.
Specify window renewal, entry zips and fasteners after assessing their existing positions. Reinforcement may be appropriate at support contact points or tensioned corners; photographs help identify these rather than assuming one standard 813 layout.
Quick Answers: Seamaster 813 Covers
Can I use a Seamaster 840 canopy sample for a Seamaster 813?
The model names do not demonstrate a shared pattern. Provide the 813's own fitted sample or agree measurements around its supports and attachments.
Can you replace windows while retaining my Seamaster 813 canopy?
Send close-ups of the windows and surrounding cloth together with an overall fitted view. Repair can be discussed if the remaining canvas is suitable.
Does 813 provide enough information for canopy measurements?
No. We need the actual cover boundary, panel junctions, support positions and fasteners. The model designation is an identification, not a measured canopy specification.
