Analysis of Your Needs
WINDSLYCE has a wide rang of RCB & Heavy Duty slider hardware for full batten mainsails. We and a number of our Associates have considerable experience with various systems and we are making this available in our FBM clinic. This works by the respondent filling out the form, giving details of difficulties. This will be looked at by our operators and a response which may ask more questions will be sent. This service is at the moment free, but qualified to limit our liability. We are happy to field queries in respect of non WINDSLYCE products or at least the common systems in Australia that we know. Being professionals we will try and avoid the obvious temptations.
There are many systems on the market and most have their field of application. Factors to be considered are:
- Maximum righting moment for mono hulls or sailing weight and centre line beam for cats
- Size of roach or leech round
- Size of mainsail
- The headboard pull off load
- Will it be desirable to reef or lower main other than head to wind?
- Is the boat a racing boat with plenty of strong crew or is it intended to cruise short handed
- What apparent wind strength will full mainsail be carried in?
- Is operating convenience not prime cost the paramount factor?
We comment on these as follows
- If the answers to 2, 3 and 4 is big & to 5 and 8 is yes & to 6 no, you are looking at the right web site.
- If you give us the give us the E (sail foot) P (sail luff) and maximum apparent wind that full sale will be carried we can calculate full sail headboard pull off force. NB The pull off for reefed sail will be greater by luff ratio for same heel angle!.
Factors which should be examined with any option are:-
- Is connection Batten / Car adequate for load.?
- Web on is strong, but with big batten forces can jamb against mast
- This is a common point of breakage
- Can the mainsail be conveniently separated from mast. ( not a great problem with sliders )?
- Will sliders allow the sail to be lowered with batten compression load laterally applied?
- What is the height of stack with sail lowered? Is this convenient ( e.g. for halyard connection)
- Is reef tack position sufficiently remote from a car/slider location?
- Has the mast track got the minimum number of joints?
- Is the headboard and just as importantly is the track and it's fastenings strong enough?
As a rough guide we give the table below. It is most important to realise that all application information given on this site can not be guaranteed unless a specific request is made with full data in writing and a specific engineering fee paid. Alternatively we will liaise with a Navel Architect or other Yachting Professional of your choice to give a complete analysis of your application. You must be aware that many yacht systems are selected on what breaks is too weak, what doesn't break is too strong. This does result in problems for the unwary.

Ronstan Series 26 and Harken B take B_R_85 cars but they are a slightly different gauge. Sorry about units 1 metre = 3.28 ft. Australians think boat length in feet, everything else in metres!
WINDSLYCE CODE 7/B, 1_SL, C_SL
This is a range of slider bodies using PTFE rods, only suitable for FBM systems. It was introduced originally at the request of Various OEM's who had stock mast sections with Ronstan 7000 track integrally extruded.
We found that by using slightly smaller rods the same car body works with Harken B systems. The PTFE rods slide very easily and have given 8-10 years service on charter boats. There are approximately 1,000 boats with these systems. The majority are catamarans.
