Modification of the over cover and cockpit cover

Since taking delivery of a new over cover and a new cockpit cover from R&J Sails in 2013, a number of the modifications made to Tra Bhui have compromised the fit and effectiveness of each cover.

Despite having fallen heir to a hand operated sewing machine, after discussion with Dick Hannaford at R&J Sails I decided that the best option would be to measure what changes were required and send the covers along with sketches and photos back to R&J Sails and ask Dick to make the required alterations rather than try and make the changes myself.

The Brief given to R&J Sails was:-

Alterations required 

Over cover 

The over cover fits the original boat very well, however it needs to be altered to accommodate the outboard and also a boarding ladder that I have fitted.

  • The outboard modification should I hope be fairly straightforward. The sizes are set out on the attached sketch. The outboard sticks up 400 mm above the gunwales. It is 350 mm wide. 
  • The boarding ladder is a stainless steel ladder that folds up against the outside edge of the gunwale (Port side). It is 300 mm wide and is positioned 920 mm from the top corner of the gunwale. Could you make a cut out in the cover to accommodate this while maintaining the edge chord (possibly making the chord disconnect able via a hook and eye)?. I have shown the position of the ladder on the sketch and I have attached  some photos - Brief has since been modified to allow option of fitting eyelet to top of cover to allow boarding ladder to be tied up when cover fitted. This would save cutting the cover back
Cockpit Cover

Since the original cover was made, I have added a tabernacle at the bottom of the mast and increased the height of the instrument cluster at the rear of the centre board housing.

The tabernacle needs to be accommodated simply by an enlarged mast opening. Sizes are given on the attached sketch. I have related everything to the centre line of the Samson Post as this is already catered for by the cover.

The instrument cluster requires an bit of a box shape to be inserted into the cover in a similar manner to the way the outboard is accommodated in the over cover. Again I have shown the required dimensions on the attached sketch.

  • Mast opening to be enlarged to accommodate a 250mm x 150mm tabernacle. The mast in it's down position is just over 280mm above the cover so an up stand of approx 200 mm would be ideal. There are a number of cleats on the tabernacle so a "baggy" cut would allow these to be accommodated - see pictures.
  • Box to be inserted into cover to accommodate enlarged instrument cluster - see sketch and pictures
I hope the above along with attached sketch and the additional pictures which will follow shortly makes the scope of the alterations clear. If you need any further information, please let me know.

Instrument Consul - sits well above cockpit seat level.

Boarding Ladder - stops over cover fitting properly

Outboard - Over cover does not accommodate this - possibly due to increase in size of outboards over the years


Cockpit cover - originally made to fit mast now needs to fit Tabernacle



The covers are due back in December - this post will be updated to show the altered covers when they are returned
