Taping the Hull Chines


Good effort Gerry. We are definitely at one of those stages where a days work doesn't seem to show much progress... chin-up!!

Without wanting to repeat Gerry's good blogging here are the salient pics and words from yesterdays effort (we snuck an afternoon off!).




Here is extruded NACA 0012 section Gerry was reffering to that we are using for the keel fin. This is a quite conservative section but will be adequate for our purposes and puts a great big tick in the "Budget Sportboat" - we could have spent time drawing a perfect section for our needs but at 250 quid.... Also using a NACA section means that everyone (who might build one) has access to the data. Can't wait to stick it in the boat.


What we should have done is left the filling of the outside chines and bogged them as we put the tape down - this would have saved us a sanding (rather green expoxy) job. There's a few hours of my life I won't get back!


A real pain as the taping went on so quickly - all we have to do is wait for this to go off..... is it time to turn her over now???

!Top Tip: We discovered that heating the resin before using made it lovely and thin and easy to use...

Stuff we used today:
80 Grit Sandpaper
Long(ish)board
Pliers & sharp knife (to remove the last of the cable ties)
50mm wide glass ape (160g)
Ampreg Epoxy and Hardener etc
Roll of Peel-ply
A couple of electic heaters

  1. What painfully great lessons you're learning (the kind that you remember, alas!)
