Alternative build

Post by Richard98 » Fri Mar 09, 2018 6:01 pm

Decided to use up my old stock of cedar planks ( at least 3 boats worth) and build a modern One Metre. Thanks Brad, have gone for your "Alternative" design. Super efficient looking lines and looks a little tricky to plank up.
Picture of starting point. Note the string passing through the 2mm datum holes in each shadow, each one is aligned by shining a bright light from the end and sighting down the hull.

Thanks for the comment Mike.
Thinking of a lowered deck aft of the mast to avoid a mast well. I know the current fashion is back to flat aft decks but It is easier, lighter and stiffer for a timber boat than a multi part well or inserting an Ikon or similar moulding.
Some more pics of progress. Rough trimmed and sanded hull.

Finished the easy bit last week; planking the hull. Epoxy coated and 50 gsm lined. Weight a constant factor. The peel ply on the inside removed 35grm of surplus resin !
Fiddly bit now: setting up mast / fin box.

Good work the photos are very helpful. I'm about to start planking an Ellipsis and am a bit concerned about the process, I understand the planking but not sure about what epoxy to use etc etc. Please update as you move forward.

Stephen, sorry for delay in responding. Boat has been on "back burner" for last few weeks.
Everyone has their favourite adhesives. I use the following:
SP 106 for structural filleting etc.
XCR coating epoxy from Easy Composites for coating. It has built in UV protection.
Aliphatic resin from Deluxe adhesive for planking. Easy clean up so all excess can be removed with the usual eye to keep weight off. It sets waterproof.

Picture to date. Ready for deck.

Hull finished, just requires tidying up and a final thin coat of epoxy, which will be flatted back with 1200 wet and dry. Then setting the trim for ballasting the fin.
Note that I have straightened out the centre line of the fore deck. Brad's drawing shows a sharp curve towards the bow. The sheer retains the sharp upturn but the deck would have been tricky in wood and heavier to achieve; requiring intermediate deck frames. The drawing does show these however.
