Material
  Wood strips
assumes bead & cove strips and you need either the 5/8" OR 3/4" strips. Not both.
Unit converter
Metric / Standard unit converter
Coverage + 'fudge factor' for waste Surface area (ft2) (m2) Total length of 3/4" strips (ft) (m) Number of 3/4"x 16ft strips Total length of 5/8" strips (ft) (m) Number of 5/8"x 16ft strips
Total area of kayak (+ cockpit) 46.5  (4,32) 894  (272) 56 1118  (341) 70
Total area + 5% 48.9  (4,54) 939  (286) 59 1174  (358) 73
Total area + 10% 51.2  (4,75) 984  (299) 61 1230  (375) 77

Notes & Tips:
  • 3/4" strip width = 1,9 cm
  • 5/8" strip width = 1,58 cm
  • 16 feet = 4,87 m
  • The accuracy of figures in the table is within (+ -) few feet
  • For custom calculation, see the Wood strip Calculator
  • The coverage based on the "+ 10%" is most recommended
  • Estimate wood for deck inlays as a percentage of the deck surface area
  • Ideal strip length is between 10 - 16 feet
  Fiberglass coverage
assumes complete coverage of inside and outside of hull and deck to make full sandwich core
 
Coverage of fiberglass
(plain weave e-glass)		 yards
(yd) 		feet
(ft) 		meters
(m) 		How to estimate
Deck - 4 oz. e-glass 11.3   10,4 two times the kayak length + 1 yard (1m)
Hull - 6 oz. e-glass 11.3   10,4 two times the kayak length + 1 yard (1m)
2" wide glass tape   71 21,6 four times the kayak length + 9 ft (3m)

Notes & Tips:
  • Minimum width of fabric is 38" - will no allow for full hull abrasion patch
  • Order 50" width of the 4oz. glass to get the extra hull abrasion patch material
  • If 50" fabric is not available, order one 'waterline length - LWL' of additional cloth (any weight)
  • Round figures to the nearest higher number when ordering fabric
  • The 6oz. glass can always replace the 4oz.
  • See different types of reinforcement fabrics
  • Glass tape is sold in 'feet' and cloth in yards (in the US)
  • Glass tape is used to bond the kayak shells and for additional stem reinforcement
  Epoxy
  Minimum total volume of epoxy mix (resin + hardener): 2 - 2.5 gallons

Notes & Tips:
  • Usage may vary (+-) 0.5 gallon as a result of the thickness of lay-up, fillet size, unused batches, spills, bad (unmixed) batches, care in application (overapplication), additional composite components such as coamings, hatch seals, rudders etc...
  • If epoxy is sold by weight, the density of epoxy is very close to water (1dm3 = 1 liter = 1kg)
  • 1 gallon = 3.8 liters
  • Learn about epoxy
