Read post #76, where I provided precisely this evidence. If you have any proa based evidence that counters this, please let us know.
For cruising boats, the drag difference between stayed and unstayed masts is much less important than the lack of maintenance
and the unstayed rig advantages of being able to tack and gybe, hoist, lower, raise and completely depower the sails
regardless of wind
strength or direction.
And the reduction of stress for all involved that this level of ease and safety
The speed difference is not about the drag. It is the ability, with the unstayed rig, to carry full sail at night, in squally conditions, when shorthanded or the forecast
is bad, knowing that, whatever the wind
strength or direction you can safely and totally depower the boat by releasing the sheet, then safely and easily reduce sail (or not, and still maintain a comfortable speed and be able to manoeuvre ) at your leisure.
I am not being coy about the weights or the cost of the Cruiser 60. I don't know them. When I do, I will make them public, the same as I do for all aspects of harryproas.
I do know that the 18m/60' leeward hull requires 3 infusions: one for each hull half, and one for all the bulkheads, bunk tops, etc. These include all the bulkhead and shelf landings, hatches, doors, joins, rebates for windows, local beefing up for beams, masts, rudders and fittings, all edge treatments and a void free laminate with no excess resin.
There is no mould polishing, cutting or grinding of cured fibreglass, laminating post infusion, bogging or fairing prior to painting inside and out, apart from the small nose pieces which are built conventionally.
I'd be interested to know how much material and time any of the builders on this thread estimate they would have saved if they had used a technique with these benefits.
it is hard to believe a discussion is happening comparing the "cost of a 30' cat" (varies from a few grand to several hundred), "space of a 40'ter" (varies from nothing to apartment size), performance of a 60'ter (varies from dead slow to extremely quick).
The original comment was not a promise, it was an indication that the Cruiser 60 will perform well, have enough space and not cost much.
Spacious enough for a family
of 5 to live in it in 4 seperate cabins, with 3 toilets/showers. It will sleep 8 if required, comfortably feed 16 in the saloon
and party 50+ outside, with somewhere for most of them to sit. Any 40' cats that can do this? or 60'ters?
The speed will depend on what extra weight goes in it, but it will weigh <4 tonnes rigged and empty so should get along ok with 120 sq m/1,200 sq' sail area.
The cost won't be known until it is finished, but if the build method works as well as it did on the 6m/20' and 12m/40' hulls we built to sort out the bugs, it won't be much. See above and estimate the savings.
