NB Tranquillity 1 Posted October 8, 2020 Report Share Posted October 8, 2020 The existing cratch on my narrowboat is built from softwood and is ,as you would expect, going rotten. I want to have it replaced in varnished hardwood so any suggestions on which hardwood to use? Gary Link to comment Share on other sites More sharing options...
Machpoint005 Posted October 8, 2020 Report Share Posted October 8, 2020 The one you can get? Are we talking about the cratch (vertical board at the front) or the king plank (horizontal, front to back)? Link to comment Share on other sites More sharing options...
NB Tranquillity 1 Posted October 8, 2020 Author Report Share Posted October 8, 2020 Vertical triangularish shape at the front, plank on top and roof board(?) at the bulkhead. I can get oak which looks great but have been told it doesn't like water and turns black. Link to comment Share on other sites More sharing options...

Tracy D'arth Posted October 8, 2020 Report Share Posted October 8, 2020 Or Keruing. Meranti for colour. Link to comment Share on other sites More sharing options...
jacko264 Posted October 17, 2020 Report Share Posted October 17, 2020 I worked with Keruing for years and it’s a good tight grain wood but it’s terrible for resins coming out of it so it’s no good to varnish on graham Link to comment Share on other sites More sharing options...
dave moore Posted October 17, 2020 Report Share Posted October 17, 2020 I’ve made deckboards out of ply, then treating them with West System resin before painting. Just a thought.... Link to comment Share on other sites More sharing options...
