Have you ever wondered how we get the grain pattern on our bulkheads to match the doors? It’s easy really, our doors are cut out from the bulkheads. Our bulkheads are laminated in place, they are made of two, 15mm thick marine grade plywood panels bonded together, there is also 0.9-1.2mm thick Sapele mahogany veneer on each side. This is the wood you see once the bulkhead is finished and we like it to match the door, perfectly. Before the bulkhead can be fitted, if there is a doorway, it needs to be added. This poses a few problems. Because every boat is individually built, one boat differs from the next so each yacht uses wood from the same tree, and this keeps the colour and grain pattern consistent throughout, but cutting out a door from a bulkhead would cause the bulkhead to flex. Even at over 30mm (1 1/4 in) thick a little flex could cause a problem and make it difficult to close a door once it’s installed. For this reason, we cut out the door, add the laminated Sapele mahogany frame to the bulkhead and 6mm of solid Sapele mahogany around the door and then fit the door into the bulkhead and secure the two together. Only then do we fit the bulkhead into position on the yacht. Once the bulkhead is securely laminated in place, the doors are removed and labelled before varnishing. The doors and the bulkheads are varnished separately. The bulkheads remain unvarnished to allow the GRP laminate and glues that attach the bulkhead to the hull to bond fully with the wood. Once the bulkheads are laminated in place, then they can be varnished, by hand and brush to give a thick, hard-wearing finish. #wearesirius #SiriusWerft #Sirius #siriusyachts #Yacht #Yachting #Sailing #Sailboat #Decksaloon #decksalon #BluewaterCruiser #OffshoreCruiser #LiftingKeel #Twinkeel #BilgeKeel #Handbuilt #Sailingyacht #Sailingboat #BlueWaterSailing #GoAnywhereCruiser #Swingkeel #OceanSailing #Circumnavigation #DreamYacht #Segeln #SailingLife #SailingLifeStyle #LiveABoard #SailingInstagram #YachtingWorld

The Alpine butterfly knot, also known as lineman's loop, butterfly loop, butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope. There are multiple ways to tie the Alpine Butterfly knot, in today's video we will teach you the wrap method where we form the knot by creating three loop around you hand to form the base of the knot. It can be tied without access to either end of the rope, this is a distinct advantage when working with long sheets or halyards. The Alpine butterfly knot is an excellent mid-line rigging knot, it handles multi-directional loading well and has a symmetrical shape that makes it easy to inspect. The Alpine Butter fly knot is great for creating temporary purchase systems which can help secure items with additional holding power. Making it great for tying down dinghies, spars, sails or just about anything you can loop your rope around. The Alpine Butterfly knot will tighten on itself making a secure loop or purchase system, it can be easily undo even after heavy load is applied making it a great temporary solution when a loop is needed. The team at bottom up boats hoped you enjoyed this Know Knots shorts video demonstration where we should you how to tie an Alpine Butterfly Knot. If you have a suggestion for other must know knots you would like a short for drop us a comment at the bottom of the video and we will give it a go. #bottomupboats
